An Overview of Proper Vehicle Service
General Motors is aware that some companies are marketing tools and equipment to support various subsystem flushing procedures.* These
dedicated machines plus many engine oil, cooling system, fuel system, air conditioning, and transmission flush options and steering system
additives are available to the consumer. GM vehicles under normal usage do not require any additional procedures or additives beyond what is
advised under the Owner's Manual maintenance schedules or the current GM Goodwrench Maintenance Schedules.
*Do not confuse machines available from Kent-Moore/SPX that are designed to aid and accelerate the process of fluid changing with these flushing
machines.

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
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.
Our Commitment to providing Quality Service to Our Customers
Most customers appreciate and gain trust in the dealership that informs and offers them just what they need for continued trouble-free operation of
their GM vehicle. Examine your service department's practices and verify that all Service Advisors and Technicians focus on providing a truly
exceptional service experience through vehicle inspections and offering appropriate products at time of service. Use this opportunity to review the
services you provide to your customers. Here are a few suggestions:
- Take the time required to align your dealership service practices with the new GM Simplified Maintenance Schedule. Use the new vehicle
Owner's Manual maintenance schedules to create a "mirror image" in your advertising and dealer service pricing that is easily understandable
to your customer. Taking advantage of this new service strategy may greatly increase your dealership service sales and customer retention
while decreasing inconvenience to your customer. Fully leveraging the Customer Sales and Service Retention marketing program, your
dealership website and in-Market Retail funds will help you personalize your marketing for each customer.
- Review your processes to ensure that your service team performs an Express Check-In on every vehicle visiting your service lane. Evaluate
them for Oil Life remaining, interior condition, tire wear, wiper condition and windshield condition. Check engine oil and washer fluid levels
and the condition of the battery and its cables. Invite your customer to join you as you inspect their vehicle. Use the Express Check-In form
provided by GM to give the customer the knowledge of the results of your findings. Time permitting; further checks can be performed such
as light function, OnStar OVD/DMN activation or GMPP registration. Both DMN and GMPP enrollment will grow your customer retention.
- Use the Goodwrench Service Inspection form when completing a service maintenance inspection. Be complete in your service
recommendations. Use the Goodwrench Service Inspection process to document vehicle needs. This information can be integrated into your
marketing efforts to the customer. Many dealers miss the services that are needed. Focus on overlooked but required maintenance that has
real benefits to the customer. Many vehicles are equipped with cabin air filters. If these filters are used beyond replacement time, they may
impede airflow decreasing A/C and heating performance. Make sure these filters are part of your service recommendations if needed. Note
that some of our vehicles may not have been factory equipped but will accept the filters as an accessory.
- Maintain your service expertise through GM Training and ASE Certification of your technicians.
- Finally, take advantage of your service initiatives (National Account Tire, Quarterly Marketing Incentive, Goodwrench Service Maintenance,
New Smart Wax Auto Detailing Products, OnStar Vehicle Diagnostic and dealer website service leads and Dealer Marketing Association
