Customer Reimbursement - For US
Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to be submitted to the dealer
by December 31, 2013, unless otherwise specified by state law. If this is not convenient for the customer, they may mail the completed Customer
Reimbursement Request Form and all required documents to the GM Customer Assistance Center. Repairs must have occurred within the 10 years
of the date the vehicle was originally placed in service, or 120,000 miles, whichever occurs first.
All reasonable and customary costs to correct the condition described in this bulletin should be considered for reimbursement. Any
questions or concerns should be reviewed with your District Service Manager - Aftersales prior to processing the request.
When a customer requests reimbursement, they must provide the following:
- A completed Customer Reimbursement Request Form. This form is mailed to the customer or can be obtained through GM GlobalConnect.
- The name and address of the person who paid for the repair.
- Paid receipt confirming the amount of the repair expense, a description of the repair, and the person or entity performing the repair.
Important
GM requires dealers to approve or deny a reimbursement request within 30 days of receipt. If a reimbursement request is approved, the
dealer should immediately issue a check to the customer and submit an appropriate warranty transaction for the incurred expense. If a
reimbursement request is denied, the dealer MUST provide the customer with a clear and concise explanation, in writing, as to why the request
was denied. The bottom portion of the Customer Reimbursement Request Form may be used for this purpose. If the denial was due to missing

Refer to the following General Motors website for dexos 1(TM) information about the different licensed brands that are currently available:
http://www.gmdexos.com
GM dexos 1(TM) Engine Oil Trademark and Icons
The dexos(TM) specification and trademarks are exclusive to General Motors, LLC.
Only those oils displaying the dexos(TM) trademark and icon on the front label meet the demanding performance requirements and stringent
2010 Cadillac Truck Escalade AWD V8-6.2L Page 347
quality standards set forth in the dexos(TM) specification.
Look on the front label for any of the logos shown above to identify an authorized, licensed dexos 1(TM) engine oil.
GM dexos 1(TM) Engine Oil Specification
Important
General Motors dexos 1(TM) engine oil specification replaces the previous General Motors specifications GM6094M, GM4718M and
GM-LL-A-025 for most GM gasoline engines.The oil specified for use in GM passenger cars and trucks, PRIOR to the 2011 model year
remains acceptable for those previous vehicles. However, dexos 1(TM) is backward compatible and can be used in those older vehicles.
In North America, starting with the 2011 model year, GM introduced dexos 1(TM) certified engine oil as a factory fill and service fill for gasoline
engines. The reasons for the new engine oil specification are as follows:
- To meet environmental goals such as increasing fuel efficiency and reducing engine emissions.
- To promote long engine life.
- To minimize the number of engine oil changes in order to help meet the goal of lessening the industry's overall dependence on crude oil.
dexos 1(TM) is a GM-developed engine oil specification that has been designed to provide the following benefits:
- Further improve fuel economy, to meet future corporate average fuel economy (CAFE) requirements and fuel economy retention by allowing
the oil to maintain its fuel economy benefits throughout the life of the oil.
- More robust formulations for added engine protection and aeration performance.
- Support the GM Oil Life System, thereby minimizing the replacement of engine oil, before its life has been depleted.
- Reduce the duplication of requirements for a large number of internal GM engine oil specifications.
Corvette Engines Built at Wixom That Require the Use of Mobil 1(TM) Oil
The following Corvette engines built at Wixom, Michigan are equipped with an OEM oil fill cap that identifies Mobil 1(TM), SAE 5W-30 as the
engine oil that is required to be used in these engines.
- Corvette Engines Built at Wixom - RPO LS7 and LS9 for the Z06 and ZR1
- Corvette Engine Built at Wixom - RPO LS3 for the Grand Sport Coupe with Manual Transmission
International Lubricants Standardization and Approval Committee (ILSAC)
GF-5 Standard
In addition to GM dexos 1(TM), a new International Lubricants Standardization and Approval Committee (ILSAC) standard called GF-5, was
introduced in October 2010.
- There will be a corresponding API category, called: SN Resource Conserving. The current GF-4 standard was put in place in 2004 and
became obsolete in October 2011. Similar to dexos 1(TM), the GF-5 standard will use a new fuel economy test, Sequence VID, which
demands a statistically significant increase in fuel economy versus the Sequence VIB test that was used for GF-4.
- It is expected that all dexos 1(TM) approved oils will be capable of meeting the GF-5 standard. However, not all GF-5 engine oils will be
capable of meeting the dexos 1(TM) specification.
- Like dexos(TM) the new ILSAC GF-5 standard will call for more sophisticated additives. The API will begin licensing marketers during
October 2010, to produce and distribute GF-5 certified products, which are expected to include SAE 0W-20, 0W-30, 5W-20, 5W-30 and
2010 Cadillac Truck Escalade AWD V8-6.2L Page 348
10W-30 oils.
Corporate Average Fuel Economy (CAFE) Requirements Effect on Fuel Economy
Since CAFE standards were first introduced in 1974, the fuel economy of cars has more than doubled, while the fuel economy of light trucks has
increased by more than 50 percent. Proposed CAFE standards call for a continuation of increased fuel economy in new cars and trucks. To meet
these future requirements, all aspects of vehicle operation are being looked at more critically than ever before.
New technology being introduced in GM vehicles designed to increase vehicle efficiency and fuel economy include direct injection, cam phasing,
turbocharging and active fuel management (AFM). The demands of these new technologies on engine oil also are taken into consideration when
determining new oil specifications. AFM for example can help to achieve improved fuel economy. However alternately deactivating and activating
the cylinders by not allowing the intake and exhaust valves to open contributes to additional stress on the engine oil.
Another industry trend for meeting tough fuel economy mandates has been a shift toward lower viscosity oils.
dexos 1(TM) will eventually be offered in several viscosity grades in accordance with engine needs: SAE 0W-20, 5W-20, 0W-30 and 5W-30.
Using the right viscosity grade oil is critical for proper engine performance. Always refer to the Maintenance section of a vehicle Owner Manual
for the proper viscosity grade for the engine being serviced.
GM Oil Life System in Conjunction With dexos(TM) Supports Extended Oil Change Intervals
To help conserve oil while maintaining engine protection, many GM vehicles are equipped with the GM Oil Life System. This system can provide
oil change intervals that exceed the traditional 3,000 mile (4,830 km) recommendation.
The dexos(TM) specification, with its requirements for improved oil robustness, compliments the GM Oil Life System by supporting extended oil
change intervals over the lifetime of a vehicle.
If all GM customers with GM Oil Life System equipped vehicles would use the system as intended, GM estimates that more than 100 million
gallons of oil could be saved annually.

Refer to the following General Motors website for dexos 2(TM) information about the different licensed brands that are currently available:
http://www.gmdexos.com
GM dexos 2(TM) Engine Oil Trademark and Icons

GM dexos 1(TM) Engine Oil Specification
Important
General Motors dexos 1(TM) engine oil specification replaces the previous General Motors specifications GM6094M, GM4718M and
GM-LL-A-025 for most GM gasoline engines.The oil specified for use in GM passenger cars and trucks, PRIOR to the 2011 model year
remains acceptable for those previous vehicles. However, dexos 1(TM) is backward compatible and can be used in those older vehicles.
In North America, starting with the 2011 model year, GM introduced dexos 1(TM) certified engine oil as a factory fill and service fill for gasoline
engines. The reasons for the new engine oil specification are as follows:
- To meet environmental goals such as increasing fuel efficiency and reducing engine emissions.
- To promote long engine life.
- To minimize the number of engine oil changes in order to help meet the goal of lessening the industry's overall dependence on crude oil.
dexos 1(TM) is a GM-developed engine oil specification that has been designed to provide the following benefits:
- Further improve fuel economy, to meet future corporate average fuel economy (CAFE) requirements and fuel economy retention by allowing
the oil to maintain its fuel economy benefits throughout the life of the oil.
- More robust formulations for added engine protection and aeration performance.
- Support the GM Oil Life System, thereby minimizing the replacement of engine oil, before its life has been depleted.
- Reduce the duplication of requirements for a large number of internal GM engine oil specifications.
Corvette Engines Built at Wixom That Require the Use of Mobil 1(TM) Oil
The following Corvette engines built at Wixom, Michigan are equipped with an OEM oil fill cap that identifies Mobil 1(TM), SAE 5W-30 as the
engine oil that is required to be used in these engines.
- Corvette Engines Built at Wixom - RPO LS7 and LS9 for the Z06 and ZR1
- Corvette Engine Built at Wixom - RPO LS3 for the Grand Sport Coupe with Manual Transmission
International Lubricants Standardization and Approval Committee (ILSAC)
GF-5 Standard
In addition to GM dexos 1(TM), a new International Lubricants Standardization and Approval Committee (ILSAC) standard called GF-5, was
introduced in October 2010.
- There will be a corresponding API category, called: SN Resource Conserving. The current GF-4 standard was put in place in 2004 and
became obsolete in October 2011. Similar to dexos 1(TM), the GF-5 standard will use a new fuel economy test, Sequence VID, which
demands a statistically significant increase in fuel economy versus the Sequence VIB test that was used for GF-4.
- It is expected that all dexos 1(TM) approved oils will be capable of meeting the GF-5 standard. However, not all GF-5 engine oils will be
capable of meeting the dexos 1(TM) specification.
- Like dexos(TM) the new ILSAC GF-5 standard will call for more sophisticated additives. The API will begin licensing marketers during
October 2010, to produce and distribute GF-5 certified products, which are expected to include SAE 0W-20, 0W-30, 5W-20, 5W-30 and
2010 Cadillac Truck Escalade AWD V8-6.2L Page 348
10W-30 oils.
Corporate Average Fuel Economy (CAFE) Requirements Effect on Fuel Economy
Since CAFE standards were first introduced in 1974, the fuel economy of cars has more than doubled, while the fuel economy of light trucks has
increased by more than 50 percent. Proposed CAFE standards call for a continuation of increased fuel economy in new cars and trucks. To meet
these future requirements, all aspects of vehicle operation are being looked at more critically than ever before.
New technology being introduced in GM vehicles designed to increase vehicle efficiency and fuel economy include direct injection, cam phasing,
turbocharging and active fuel management (AFM). The demands of these new technologies on engine oil also are taken into consideration when
determining new oil specifications. AFM for example can help to achieve improved fuel economy. However alternately deactivating and activating
the cylinders by not allowing the intake and exhaust valves to open contributes to additional stress on the engine oil.
Another industry trend for meeting tough fuel economy mandates has been a shift toward lower viscosity oils.
dexos 1(TM) will eventually be offered in several viscosity grades in accordance with engine needs: SAE 0W-20, 5W-20, 0W-30 and 5W-30.
Using the right viscosity grade oil is critical for proper engine performance. Always refer to the Maintenance section of a vehicle Owner Manual
for the proper viscosity grade for the engine being serviced.
GM Oil Life System in Conjunction With dexos(TM) Supports Extended Oil Change Intervals
To help conserve oil while maintaining engine protection, many GM vehicles are equipped with the GM Oil Life System. This system can provide
oil change intervals that exceed the traditional 3,000 mile (4,830 km) recommendation.
The dexos(TM) specification, with its requirements for improved oil robustness, compliments the GM Oil Life System by supporting extended oil
change intervals over the lifetime of a vehicle.
If all GM customers with GM Oil Life System equipped vehicles would use the system as intended, GM estimates that more than 100 million
gallons of oil could be saved annually.

Important:
This bulletin is not applicable to vehicles operating in Canada on Canadian sourced fuels. Canadian regulations limit the amount of sulfur in
gasoline to 80 PPM or less for all gasoline marketed in Canada with no exemptions.
Federal regulations limit the amount of sulfur in gasoline to 80 PPM (some states have lower limits; for example, California's limit is 30
PPM). The federal exception to this rule is an allowance for qualifying small refineries that permits up to 450 PPM until January 1, 2011. Sulfur
odor in exhaust from vehicles equipped with gasoline engines is caused by excess sulfur in the gasoline and it cannot be eliminated unless the
source of the sulfur is eliminated.
Important:
Replacement of catalytic converters for this condition is not an appropriate repair and will not correct the condition by itself.
Customers with vehicles that exhibit this condition should be advised of the information in this bulletin and be asked to switch the brand of gasoline
that they are using. In most cases, this will result in elimination of the sulfur odor by the time one tank full of gasoline is consumed if the gasoline
that was added is within the 80 PPM federal limit.
In order for the odor to be eliminated. two things must occur. First, the gasoline added to the vehicle must be at or below the federal 80 PPM limit.
Secondly, the vehicle must have run long enough to have consumed one tank of fuel containing a sulfur content of 80 PPM or less.
Although there is no way for a dealership to easily measure the amount of sulfur in gasoline, it's a good practice when asked for a recommended
brand of gasoline to recommend any of the Top Tier Detergent Gasoline Brands. Although Top Tier brands have not demonstrated that they contain
a lower sulfur content than other brands, their detergent additive package makes them a preferred choice when choosing a brand of gasoline for
your vehicle. A complete list of Top Tier Brands can be found in Corporate Bulletin Number 04-06-04-047H (in Canada, refer to Corporate
Bulletin Number 05-06-04-022E) or by accessing the website www.toptiergas.com.

gasoline to 80 PPM or less for all gasoline marketed in Canada with no exemptions.
Federal regulations limit the amount of sulfur in gasoline to 80 PPM (some states have lower limits; for example, California's limit is 30
PPM). The federal exception to this rule is an allowance for qualifying small refineries that permits up to 450 PPM until January 1, 2011. Sulfur
odor in exhaust from vehicles equipped with gasoline engines is caused by excess sulfur in the gasoline and it cannot be eliminated unless the
source of the sulfur is eliminated.
Important:
Replacement of catalytic converters for this condition is not an appropriate repair and will not correct the condition by itself.
Customers with vehicles that exhibit this condition should be advised of the information in this bulletin and be asked to switch the brand of gasoline
that they are using. In most cases, this will result in elimination of the sulfur odor by the time one tank full of gasoline is consumed if the gasoline
that was added is within the 80 PPM federal limit.
In order for the odor to be eliminated. two things must occur. First, the gasoline added to the vehicle must be at or below the federal 80 PPM limit.
Secondly, the vehicle must have run long enough to have consumed one tank of fuel containing a sulfur content of 80 PPM or less.
Although there is no way for a dealership to easily measure the amount of sulfur in gasoline, it's a good practice when asked for a recommended
brand of gasoline to recommend any of the Top Tier Detergent Gasoline Brands. Although Top Tier brands have not demonstrated that they contain
a lower sulfur content than other brands, their detergent additive package makes them a preferred choice when choosing a brand of gasoline for
your vehicle. A complete list of Top Tier Brands can be found in Corporate Bulletin Number 04-06-04-047H (in Canada, refer to Corporate
Bulletin Number 05-06-04-022E) or by accessing the website www.toptiergas.com.

This bulletin is being revised to add the 2010 model year and information about retrieving calibrations on a Global A vehicle. Please discard
Corporate Bulletin Number 09-06-04-026A (Section 06 - Engine/Propulsion System).
General Motors is identifying an increasing number of engine, transmission and catalytic converter part failures that are the result of non-GM
(aftermarket) engine and transmission control calibrations being used.
When alteration to the GM-released engine or transmission control calibrations occurs, it subjects powertrain and driveline components (engine,
transmission, transfer case, driveshaft and rear axle) to stresses that were not tested by General Motors. It is because of these unknown stresses, and
the potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED dealer
warranty claim submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM
(aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed.
Warranty coverage is based on the equipment and calibrations that were released on the vehicle at time of sale, or subsequently updated by GM.
That's because GM testing and validation matches the calibration to a host of criteria that is essential to assure reliability, durability and emissions
performance over the life of the warranty coverage and beyond. Stresses resulting from calibrations different from those tested and released by GM
can damage or weaken components, leading to poor performance and or shortened life.
Additionally, non-GM (aftermarket) issued engine control modifications often do not meet the same emissions performance standards as GM issued
calibrations. Depending on state statutes, individuals who install engine control module calibrations that put the vehicle outside the parameters of
emissions certification standards may be subject to fines and/or penalties.
This bulletin outlines a procedure to identify the presence of non-GM (aftermarket) calibrations. GM recommends performing this check whenever
a hard part failure is seen on internal engine or transmission components, or before an engine assembly or transmission assembly is being replaced
under warranty. It is also recommended that the engine calibration verification procedure be performed whenever diagnostics indicate that catalytic
converter replacement is indicated.
The PQC has a process to confirm the ECM/PCM calibration is GM issued. The PQC will require a picture of the engine calibration verification
screen, as outlined in this bulletin, before authorizing any V8 gas powered engine replacement.
If a non-GM calibration is found and verification has taken place through GM, the remaining powertrain and driveline warranty will be blocked and
notated in GMVIS and the dealership will be notified. This block prevents any UNAUTHORIZED warranty claim submission.

Mirrors - Heated Mirrors, Defrosting Time
INFORMATION
Bulletin No.: 08-08-64-011A
Date: February 25, 2010
Subject: Information on Heated Electrochromatic Outside Rearview Mirror Performance
Models:
2010 and Prior GM Passenger Cars and Light Duty Trucks (including Saturn)
2009 and Prior HUMMER H2, H3
2009 and Prior Saab 9-7X

This bulletin is being revised to update the model years. Please discard Corporate Bulletin Number 08-08-64-011 (Section 08 - Body and
Accessories).
Defrosting Time/Performance Concern
The electrochromatic (auto-dimming) outside rearview mirror used on the driver's side of many GM vehicles is slower to defrost than the passenger
side outside rearview mirror.
This is a normal condition. The glass on the driver's side electrochromatic mirror is twice as thick as the traditional glass on the passenger side
mirror. The heating elements for the mirrors on both sides draw the same wattage, therefore the driver's side mirror will take approximately twice as
long to defrost as the passenger mirror (approximately four minutes versus two minutes). Should a customer indicate that the driver's side heated
mirror is not functioning correctly, verify it's function based upon this information prior to replacing the mirror.

This bulletin is being revised to add the 2010-2013 model years. Please discard Corporate Bulletin Number 08-08-46-004 (Section 08 - Body and
Accessories).
This bulletin is being issued to provide dealer service personnel with information regarding aftermarket devices connected to the Diagnostic Link
Connector (DLC) and the impact to OnStar(R) diagnostic probes and Vehicle Diagnostic e-mails.
Certain aftermarket devices, when connected to the Diagnostic Link Connector, such as, but not limited to, Scan Tools, Trip Computers, Fuel
Economy Analyzers and Insurance Tracking Devices, interfere with OnStar's ability to perform a diagnostic probe when requested (via a blue
button call) by a subscriber. These devices also prohibit the ability to gather diagnostic and tire pressure data for a subscriber's scheduled OnStar(R)
Vehicle Diagnostic (OVD) e-mail.
These aftermarket devices utilize the Vehicle's serial data bus to perform data requests and/or information gathering. When these devices are
requesting data, OnStar(R) is designed not to interfere with any data request being made by these devices as required by OBD II regulations.
The OnStar(R) advisor is unable to definitively detect the presence of these devices and will only be able to inform the caller or requester of the
unsuccessful or incomplete probe and may in some cases refer the subscriber/requester to take the vehicle to a dealer for diagnosis of the concern.
When performing a diagnostic check for an unsuccessful or incomplete OnStar(R) diagnostic probe, or for concerns regarding completeness of the
OnStar(R) Vehicle Diagnostic (OVD) e-mail, verify that an aftermarket device was not present at the time of the requested probe. Regarding the
OVD e-mail, if an aftermarket device is interfering (including a Scan Tool of any type), the e-mail will consistently display a "yellow" indication in
diagnostics section for all vehicle systems except the OnStar(R) System and Tire Pressure data (not available on all vehicles) will not be displayed
(i.e. section is collapsed). Successful diagnostic probes and complete OVD e-mails will resume following the removal or disconnecting of the
off-board device.

Body - Non-Approval of Clipping For Collision Repair
INFORMATION
Bulletin No.: 07-08-98-001A
Date: January 28, 2009
Subject:
Non-approval of "Clipping" (Sectioning of Two Vehicles) For Collision Repair
Models:
2000-2010 GM Passenger Cars and Trucks (Including Saturn and Saab)
2003-2010 HUMMER H2, H3, H3T
Supercede:
This bulletin is being revised to add model years through 2010. Please discard Corporate Bulletin Number 07-08-98-001 (Section 08 - Body and
Accessories).
General Motors does not approve the use of "clipping" to repair collision damage to vehicles. In the collision repair industry, "clipping" refers to
cutting two damaged vehicles through the windshield pillars, the rocker panels, and across the floor pan and joining the undamaged portions from
these vehicles to make the repair.
The use of "clipping" voids GM's New Vehicle Limited Warranty (and any variety of the GM Protection Plan, as well as GM's new vehicle service
part and corrosion warranties) for each part in the clip.
GM does not sanction clipping repair because it cuts across the major load-bearing paths of a vehicle and can reduce the structural integrity of the
repaired vehicle. This is extremely critical because of the increase in the use of Advance High Strength Steel (AHSS). Improper repairs can lead to
vehicle performance issues related to noise, vibration and handling problems.
GM recommends replacing body components at factory seams. When applicable, GM will provide a specific service part for collision repair frames,
or provide repair information on how to create specific parts from a complete service assembly. Frame repair procedures for select GM vehicles are
available at http://www.goodwrench.com/gmgoodwrenchjsp/gmspo/techrepair_index.jsp. These parts and procedures provide a practical and
cost-effective alternative to clipping. GM provides vehicle specific collision repair procedures which are developed to be in a location and fashion
2010 Cadillac Truck Escalade AWD V8-6.2L Page 227
that will yield panel strength comparable to the original panel strength. Replacing damaged parts of a vehicle designed to crush in a collision may
reduce occupant protection in a future collision.
GM has not tested or validated a "clipped vehicle" repair; therefore, GM cannot endorse this type of repair or confirm the crash performance during
a subsequent collision. GM recommends the use of genuine GM parts in repairs to help ensure the vehicle is returned to pre-collision condition.

Some customers may comment that there are unusual fan type noises coming from the navigation radio. Additionally, the customer may comment
on radio noise coming from the CD/DVD or MAP disc mechanisms when CDs/DVDs or MAP discs are present in the CD mechanisms. Some
customers have mentioned that radio noise is present when the customer enters the vehicle or that the noise continues after they shut the vehicle off
and open the door to leave the vehicle. This noise has been described as a fan sound or hearing a disc spinning.
Source of fan sound - It is normal for the radio fan to run when the vehicle is turned on and for up to three minutes after the vehicle has been
turned off and the driver's door has been opened or closed.
Disc spinning sound - This is a normal operational sound. This is caused by the map disc spinning behind the tilt screen. It is a normal operation
after the RKE is used to unlock the vehicle or when the driver's door has been opened. This noise will also be heard during vehicle operation and up
to three minutes after the vehicle has been turned off and driver's door has been opened and closed.
MAP Disc Accessing "ZIP" sound - As the Navigation Radio accesses the MAP Disc, the customer may describe frequent "zip" type noises. This
noise is caused by the CD Read Lens moving across the disc to access needed data for proper MAP display. To determine if the source of the noise
is from accessing the MAP Disc, remove the MAP Disc to determine if the noise continues. With the addition of the Real Time NAV Traffic
Feature, the MAP CD may be accessed to a greater extent thus resulting in additional MAP Drive noise.
Inform the customer about these noises. If the customer believes the noise is not normal, compare the condition to a like vehicle with identical
settings to determine if there is a noticeable difference.
Do not replace the radio as the described conditions are normal operating characteristics.

Service is Important to You and Your Customer
General Motors takes great pride in offering our dealerships and customers high quality vehicles that require extremely low maintenance over the
life of the vehicle. This low cost of ownership builds repeat sales and offers our customers measurable economy of operation against competing
vehicles. Our goal is to make the customer experience a key driver of why customers purchase GM products and services. Providing
responsible services at the proper intervals supports this goal and will help your dealership earn repeat business.
An Overview of Proper Vehicle Service
Today, many of your service departments merchandise supplemental services and fluids to customers indicating that these "flushes" have a positive
effect on durability of the component part. It should be noted that analyses of returned parts that have been exposed to these aftermarket "flushes"
show indications of potential damage and shortened durability.
The following information clearly defines the guidelines for servicing GM vehicles.
GM Authorized Service Information is Detailed, Descriptive and Complete
If GM determines that a specific model vehicle or powertrain needs supplemental service, GM will issue an Authorized Service Document with
detailed service procedures that will identify any machine, tool or chemical required to conduct proper vehicle servicing. Listed below are a few
examples of those messages as well as additional guidelines:
Engine Crankcase Flushing
General Motors Corporation does not endorse or recommend engine crankcase flushing for any of its gasoline engines. Analysis of some of
the aftermarket materials used for crankcase flushing indicate incompatibility with GM engine components and the potential for damage to some
engine seals and bearings. Damage to engine components resulting from crankcase flushing IS NOT COVERED under the terms of the New
Vehicle Warranty.
Subsystem Flushing
Flushing of air conditioning (A/C) lines, radiators, transmission coolers, and power steering systems are recognized practices to be performed after
catastrophic failures or extreme corrosion when encountered in radiators. For acceptable A/C flushing concerns, refer to the Flushing procedure in
2010 Cadillac Truck Escalade AWD V8-6.2L Page 22
Service Information (SI). This practice is not required or recommended for normal service operations.
The use of external transmission fluid exchange or flush machines is not recommended for the automatic or manual transmission. Use of external
machines to replace the fluid may affect the operation or durability of the transmission. Transmission fluid should only be replaced by draining and
refilling following procedures in Service Information (SI). Refer to Automatic/Manual Transmission Fluid and Filter Replacement.
Approved Transmission Flushing Tool (Transmission Cooler Only)

Service is Important to You and Your Customer
General Motors takes great pride in offering our dealerships and customers high quality vehicles that require extremely low maintenance over the
life of the vehicle. This low cost of ownership builds repeat sales and offers our customers measurable economy of operation against competing
vehicles. Our goal is to make the customer experience a key driver of why customers purchase GM products and services. Providing
responsible services at the proper intervals supports this goal and will help your dealership earn repeat business.
An Overview of Proper Vehicle Service
Today, many of your service departments merchandise supplemental services and fluids to customers indicating that these "flushes" have a positive
effect on durability of the component part. It should be noted that analyses of returned parts that have been exposed to these aftermarket "flushes"
show indications of potential damage and shortened durability.
The following information clearly defines the guidelines for servicing GM vehicles.
GM Authorized Service Information is Detailed, Descriptive and Complete
If GM determines that a specific model vehicle or powertrain needs supplemental service, GM will issue an Authorized Service Document with
detailed service procedures that will identify any machine, tool or chemical required to conduct proper vehicle servicing. Listed below are a few
examples of those messages as well as additional guidelines:
Engine Crankcase Flushing
General Motors Corporation does not endorse or recommend engine crankcase flushing for any of its gasoline engines. Analysis of some of
the aftermarket materials used for crankcase flushing indicate incompatibility with GM engine components and the potential for damage to some
engine seals and bearings. Damage to engine components resulting from crankcase flushing IS NOT COVERED under the terms of the New
Vehicle Warranty.
Subsystem Flushing
Flushing of air conditioning (A/C) lines, radiators, transmission coolers, and power steering systems are recognized practices to be performed after
catastrophic failures or extreme corrosion when encountered in radiators. For acceptable A/C flushing concerns, refer to the Flushing procedure in
2010 Cadillac Truck Escalade AWD V8-6.2L Page 22
Service Information (SI). This practice is not required or recommended for normal service operations.
The use of external transmission fluid exchange or flush machines is not recommended for the automatic or manual transmission. Use of external
machines to replace the fluid may affect the operation or durability of the transmission. Transmission fluid should only be replaced by draining and
refilling following procedures in Service Information (SI). Refer to Automatic/Manual Transmission Fluid and Filter Replacement.
Approved Transmission Flushing Tool (Transmission Cooler Only)
The Automatic Transmission Oil Cooler Flow Check and Flush Tool IS recommended for GM vehicles. Refer to Transmission Fluid Cooler Flow
Check and Flush in the Service Information website using the J-45096.

The Use of "Surface Conditioning Disks"
Notice
Do not use abrasive pad/bristle devices to clean the gasket surfaces of engine components. Abrasive pads should not be used for the following
reasons:
- Abrasive pads will produce fine grit that the oil filter will not be able to remove from the oil. THIS GRIT IS ABRASIVE AND HAS BEEN
KNOWN TO CAUSE INTERNAL ENGINE DAMAGE. Abrasive pads can easily remove enough material to round cylinder head surfaces.
This has been known to affect the gasket's ability to seal, especially in the narrow seal areas between the combustion chambers and coolant
jackets.
- Abrasive pads, wire and abrasive rubber finger wheels can also remove enough metal to affect cylinder head, block, oil pan rail, and intake
manifold runner flatness, which can cause coolant and oil leaks and air leaks. It takes about 15 seconds to remove 0.203 mm (0.008 in) of
metal with an abrasive pad.
- Abrasive pads, Abrasive rubber fingers wheels & wire wheels with high speeds grinders produce air bourn debris that can travel throughout
the shop contaminating other work being performed outside of the immediate work area.
When cleaning engine gasket sealing surfaces and/or cleaning parts from an engine that are to be reused, surface conditioning disks (typically
constructed of woven fiber or molded bristles) that contain abrasives, such as a high amount of Aluminum Oxide, should NOT be used.
The use of such surface conditioning disks dislodges Aluminum Oxide (from the disk) and metal particles, which can lead to premature engine
bearing failure.
The presence of Aluminum Oxide in engine oil has been shown to cause premature engine bearing failure. In some cases, this failure occurs in as
little as 2,200 km (1,000 mi) or less after the repair has been made.
Surface conditioning disks may grind the component material and imbed it into the disk. This can result when more aggressive grinding of the
gasket surface takes place.
Recommended Cleaning Procedure
General Motors recommends the use of a razor blade or plastic gasket scraper to clean the gasket surface on engine components that are to be
reused. When cleaning gasket surfaces, please note the following:
- When using a razor blade type gasket scraper, use a new razor blade for each cylinder head and corresponding block surface. Hold the blade
as parallel to the gasket surface as possible. This will ensure that the razor blade does not gouge or scratch the gasket surfaces.
- Do not gouge or scrape the combustion chamber surfaces.
- Do not gouge or scratch any engine-sealing surface during the cleaning process.
Alternative Cleaning Method:
To properly clean the sealing surface prior to reassembly, GM Low VOC Cleaner, P/N 19287401 (in Canada, PN 88901247), should be sprayed on
the mating surface. Use care to avoid getting solvent in any area other than the mating surface to be cleaned. Allow it to soak in for several minutes
to loosen the old RTV sealer/gasket material. GM strongly recommends using a plastic razor blade or non- metallic scraper to remove all loose
sealer/gasket material.
Important
The appearance of the gasket surface is not critical - the feel is. There will be indentations from the gasket left in the cylinder head after all
the gasket material is removed. The new gasket will fill these small indentations when it is installed.
