Tech II

Tech II is an advanced diagnostic tool specifically designed for GM vehicles. Goodwrench Service technicians use this sophisticated software to instantly access the very latest service inspection information.

DEX-COOLTM

GM was the first to use DEX-COOLTM long lasting, corrosion inhibiting engine coolant as a standard production product. For you, this means less hassle. With proper recommended maintenance DEX-COOLTM requires changing just once every five years (or 240,000 km) instead of every two years like regular coolants*. DEX-COOLTM contains no phosphates, silicates or nitrates. It is recyclable, and its longer life also means less impact on the environment in terms of disposal and the consumption of non-renewable resources. If your vehicle has DEX-COOLTM, Goodwrench Service technicians will only use DEX-COOLTM. If it doesn't, they'll be sure to use the right coolant for your vehicle*.

*Maintenance requirements vary with use and driving conditions. See Owner's Manual for more information. Warning, do not mix DEX-COOL with other coolants.

Platinum-Tipped Spark Plugs

All GM vehicles are equipped with long lasting platinum-tipped spark plugs. They conduct electricity more effectively than standard spark plugs for improved fuel economy and smoother acceleration. They are also an integral part of GM engine technology that has reduced harmful emissions by more than 90% since the 1970's. Platinum-tipped spark plugs only need to be replaced every 166,000 km*. Goodwrench Service technicians only use platinum-tipped spark plugs and only replace plugs when they need replacing.

*Maintenance requirements vary with use and driving conditions. See Owner's Manual for more information.

Tire Pressure Monitor

Tires can lose up to one pound of pressure per square inch a month without notice. General Motors developed the Tire Pressure Monitor (TPM) to alert drivers before tire inflation levels become dangerous.* Keeping tires properly inflated also extends tire life and reduces wear on other components. Reducing wear means consuming fewer natural resources (and creating less waste) by extending component life. Goodwrench technicians will recalibrate the TPM whenever your tires are rotated.

*Note: It is important to check tire pressure on a regular basis whether your vehicle has the TPM or not. Only available on some GM vehicles.

Dexron-III

Extended-life, oxidation-resistant Dexron-III transmission fluid is designed to last the lifetime of your vehicle under regular driving conditions*. Because this product lasts longer, less petrochemicals are required or have to be disposed of. Goodwrench Service technicians know when your transmission fluid doesn't need changing, saving you time and money.

* Maintenance requirements vary with use and driving conditions. See Owner's Manual for more information.

GF4 Motor Oil

dentifiable by its distinctive "Starburst" symbol, GF4 Motor Oil has a longer life and contributes to increased fuel efficiency, increased emissions system protection* and reduced oil consumption. Fewer oil and oil filter changes save you time and money. Using (and disposing of) less petrochemicals means a reduced impact on the environment. Whether your vehicle has GF4 Motor Oil or not, Goodwrench Service technicians only change your oil when it's required.
