Service is Important to You and Your Customer
General Motors of Canada Limited (GMCL) 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 support this goal and will help your dealership earn repeat business.

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.
*Do not confuse machines available from Bosch (Kent-Moore/SPX) that are designed to aid and accelerate the process of fluid changing with these flushing
machines.
Additional information for General Motors maintenance recommendations is found in the “Following GM Maintenance” Video On Demand (VOD) series located
in LMS.
This series consists of three modules:

•

KVVCFM.011V1 - Following GM Maintenance Part 1 - Engine Oil

•

KVVCFM.011V2 - Following GM Maintenance Part 2 - Brake Service

•

KVVCFM.011V3 - Following GM Maintenance Part 3 - Servicing Fluids

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
1

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, detailing opportunities, 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, Chevrolet, Buick, GMC, Cadillac Maintenance Plan (HOL2015–610R01) or GMPP registration. DMN, Chevrolet / Buick / GMC / Cadillac
Maintenance Plan and GMPP enrollment will grow your customer retention.

•

Use the Certified Service Inspection form when completing a service maintenance inspection. Be complete in your service recommendations. Use the
Certified 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, GM Maintenance Schedule, New Smart Wax Auto
Detailing Products, OnStar Vehicle Diagnostic and dealer website service leads and Dealer Marketing Association (DMA) Promotions) to provide your
customers with more reasons to identify your dealership as the best place to go for parts and service.
Remember to utilize ALL of the service expertise and training you possess in your dealership to satisfy and provide a truly exceptional experience for all
your customers. The local competition in your area is fierce. It’s up to you and your team to exceed customer expectations every time. You have the
expertise and are empowered to provide the necessary services, earn the trust of your customer and grow your business.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
