Your GM vehicle carries a 3 year or 60 000 km comprehensive limited warranty (Buick models carry a 4 year or 80 000 km warranty).

GM expects that all owners will perform basic visual inspections of oil level, coolant level, windshield washer fluid level and tire pressure at each fuel fill .

Maintenance intervals, checks, inspections, replacement parts, and recommended fluids and lubricants changes as outlined by your GM maintenance manual are necessary to keep your vehicle in good working condition.

Any damage caused by failure to follow scheduled maintenance may not be covered by warranty.

Semi Annual Service
Our GM recommended maintenance schedule could significantly reduce your service visits.
Rather than setting out expensive generic "must do" maintenance schedules like the competition, we recommend just two dealership maintenance inspections a year plus regular oil changes keeps your vehicle protected.

The GM Semi-Annual service allows our factory trained technicians to inspect your vehicles systems and identify any additional maintenance items you may need to complete to extend the individual component life of your vehicle based on your driving habits.

Tire rotation, weatherstrip lubrication AND complete inspection of: restraint system, throttle system, automatic/manual transmission/transaxle, engine air cleaner filter, wiper blades, engine cooling system, brakes & tires, steering & suspension.

At Larry Hudson Pontiac Buick, we offer a special "Semi-Annual Service with Lube Oil and Filter" at a price lower than the combined price.

Lube Oil and Filter
A regular oil change is important because dirty engine oil and a clogged oil filter will decrease your engine's efficiency, and can lead to engine damage requiring expensive repairs. Goodwrench Service Technicians know the right oil is vital for the proper operation of the GM Oil Life System.

Most GM vehicles are now equipped with the GM Oil Life System (OLS) which monitors oil wear and indicates when an oil change is required. The time and kilometres between necessary oil changes will vary depending on your driving habits.

You should change your oil when indicated by the OLS light on your instrument panel, or every 12 months (whichever comes first). When the OLS light on your instrument panel lights up, change your oil within the next 1000 Km. Vehicles not equipped with the GM OLS should have a lube oil and filter every 5000km or 3 months.

Tire Inspection and Rotation
Tires are warranted under your GM Basic Warranty up to 3 years or 60 000 km for material and workmanship defect only. To support this warranty, customers are expected to perform and record tire rotations every 8-10 000km and check for accurate tire pressure and unusual wear once a month.

Tires can lose up to one pound of pressure per square inch a month without notice. 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.

Normal tire wear or wear-out, road-hazard damage such as punctures, cuts, snags and breaks resulting from pothole impact, curb impact, or from other objects, are not covered. Also, damage from improper inflation, spinning (as when stuck in mud or snow), tire chains, racing, improper mounting or dismounting, misuse, negligence, alteration, vandalism, or misapplication is not covered.

Brake Services
The friction brake components on your vehicle are warranted on your vehicle under your GM basic warranty for material and workmanship defect. Brake rotors are warranted to 60 000 and consideration will be given for covering brake pads up to 39,000 km (24,000 mi) (excluding owner abuse, excessive trailering, or the situations that would not be considered normal use ) for material or workmanship defect.

Different vehicles and consumer driving habits will wear components differently. Pads and rotors must be adjusted to a matched position to ensure effective braking and minimize wear. Recommendations for brake services to prevent premature wear will be made as noticed on semi-annual services.

Air Filter Check/ Replace
The engine air cleaner filter prevents dust from entering your engine and causing damage. A dirty filter can restrict air flow to the engine.

GM recommends every 20, 000 km or two years to replace your vehicles air filter and to check the air filter at every semi-annual inspection for unusual restriction or debris.

Fuel Filter Replace
Traditionally, your vehicle's fuel filter, an inline sealed steel filter which prevented any debris from entering the pump, was to be changed every 40-50 000 km.

As systems change and fuel supplies are made cleaner, more GM vehicles have fuel filters inside the tank itself and do not require replacement unless the tank is serviced.

Cabin Air Filter Check/Replace
In response to customer desire for more "allergen free" driving, GM has incorporated passenger compartment filters in many of the newer models.

It is important for you to check or have these cabin air filters checked once a year or every 25 000 km and replaced frequently to ensure effectiveness.

As these filters are "hepa"designed, you will find that they trap many undesired environmental pollutants and will restrict heating, cooling and general air flow in the cabin if they are not clean.

Cooling System Service
GM was the first to use DEX-COOL™ long lasting, corrosion inhibiting engine coolant as a standard production product.

For you, this means less hassle. With proper recommended maintenance DEX-COOL™ requires changing just once every five years (or 240,000 km) instead of every two years like regular ethylene glycol coolant.

* DEX-COOL™ 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-COOL™, Goodwrench Service technicians will only use DEX-COOL™. (*most 2003-2005 Vibe and Wave models still contain "green" ethylene glycol coolant.)

Transmission Service
Like engine oil, transmission/transaxle fluid and filters become contaminated with use and require regular replacement to prevent wear and damage to moving metal parts. This reduces the possibility of breakdowns and expensive repairs.

Every 80 000 kilometers Goodwrench Service Technicians inspect your vehicle's transmission for leaks. We replace the transmission fluid, gasket and filter, and adjust the linkage (if necessary). We also road test your vehicle both before and after service.

Spark Plug Replacement
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 do not require checking unless drivability is an issue and 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.

Your spark plug wires will be inspected at plug replacement and require replacement only as recommended by contamination or wear.
