Full Synthetic Oil Change (Cars and Crossovers)
dexos Gen 3 is designed to meet performance needs of GM vehicles. dexos 3 is improved to protect today’s engines that are built and engineered with tighter tolerances, often having advanced system such as Turbo Chargers, which bring additional heat and stresses to your engine. Protect your engine further with GM dexos Gen 3.
Why: Over time, the fast-moving parts in your engine breakdown the oil and lessen its ability to absorb heat and lubricate internal parts. If you continue to drive your vehicle with the same oil your engine has a very good chance of overheating or simply seizing all together. The new oil from an oil change allows the engine to run smoother, cleaner and safer.

Protect your engine further with GM dexos Gen 3.
Why: A typical engine contains many metal parts that move extremely close together thousands of times per minute. Over time, heat and contaminants degrade the oil, reducing its lubricating properties—which can cause increased wear on the engine's internal components. The oil filter, which is replaced at each oil change, also helps by physically filtering out various contaminants to keep the oil as clean and slippery as possible.

Seasonal Tire Swap
Remove and install Winter Tires and Summer Tires for seasonal driving requirements.
Why: Driving on winter tires when the temperatures start heading above 7c can cause excessive wear and tear, which is not only unsafe but will also cost you money as they degrade faster. Summer tires have a specialized compound that gets stiff and does not have flexibility in the cold, therefore reducing your braking distance and provides less traction. Braking is the most important thing your car needs to be able to do, so ensure your vehicle runs properly by using the right every season.

Wheel Alignment service
Your vehicle's wheel alignment affects a number of critical elements of drivability, including fuel efficiency, tire wear, tire performance, vehicle stability and overall handling or steering responsiveness.
Why: As your suspension parts wear, or any time your suspension takes a hit, whether by hitting a pot hole, a curb, or anything in a minor accident, it can cause the alignment to get knocked out of place. It’s important that wheels and tires are aligned. If they aren’t, you could be damaging your tires and affecting the vehicle’s handling characteristics. It’s dangerous to drive on uneven tires, and it could force you to purchase tires sooner than you would have needed to with a proper alignment.

tire rotation service
Tire rotations are necessary to keep your tires in optimal health and performance. Tire rotations are a way of managing the tread wear on your tires. It's also about extending the life of your tires.
Why: Depending on the vehicle you drive, certain tires come into contact with the road more heavily then others. Over time, those tires get worn down faster. Rotating the tires switches the positions of tires so that the still-fresh and deeper treaded tires are now in a new position and they will wear more evenly. If your treads become to low, you risk losing traction with the road, hydroplaning and will have reduced traction in snow and ice. The main concern is also that excessive strain could cause a puncture or blowout. Be sure to get this service done every 6 months or 12,000KM. A tire rotation is included with a Vehicle Health Check Service.

Cabin Air Filter - GM GENUINE PARTS
Your cabin air filter helps to ensure the air you're breathing is free of allergens, harmful bacteria and pollutants. The filter should be replaced every 36,000km, as outlined in your owner's manual.
Why: You likely need a new cabin air filter if you notice that the air coming through your vehicle’s interior vents is blowing with considerably less force and if it carries an unpleasant musty odor. Without a working cabin air filter, the air inside of a vehicle’s cabin is prone to having higher levels of harmful and odorous exhaust gases than the air outside of the cabin. And, they also help keep pollen and other allergens from entering the vehicle as well.

ACDelco Beam Wiper Blades (Set of 2)
ACDelco beam wiper blades are designed with your vehicle in mind. Beam wiper blades are designed with infinite pressure points to provide a consistent wipe across your windshield. Streaking is a sign that your wiper blades need replacing.
Why: Your wiper blades should be changed about every six months, either with the seasons or in response to regular wear and tear from use and exposure. Making sure your wiper blades are in good condition and appropriate for the weather will improve your visibility and help to keep you safe on the road. When winter comes around, changing your summer wiper blades to winter wiper blades will help protect your windshield against ice, sleet and snow, so you can see the road clearly.

Brake Pad Replacement Service
ACDelco Brake Pads are the high-value option for GM vehicles and most other makes and models. They follow essential GM Genuine Parts designs to diminish noise, vibration and braking harshness.
Why: Each time you use your brakes, a minute amount of material is removed. Eventually, they start to wear thin which means they become less effective at generating friction. This decreases the vehicle from being able to stop quickly and effectively, potentially increasing your stopping distances. You may also hear scraping or squealing noises. If your brakes start to make a grinding sound, it's time to immediately get them replaced by a Roy Foss Certified Service mechanic.

brake fluid service
A brake fluid flush involves draining out contaminated or old fluid from your brake system and replacing it with clean and fresh brake fluid. Flushing helps maintain the health and effectiveness of your vehicle’s brakes.
Why: Many of your brake parts are linked together using brake lines and hoses, which use brake fluid to transmit and amplify forces. That’s why it’s essential to ensure that the brake fluid retains its quality and doesn’t hamper the functioning of your other brake parts. Corrosion and rust can cause structural damage to your braking system, leading to costly repairs. Regular brake fluid service can prevent these deeper system issues from occurring.

Brake Rotor Replacement Service
ACDelco Brake Rotors are the high-value option for GM vehicles and most other makes and models. They follow essential GM Genuine Parts designs to diminish noise, vibration and braking harshness.
Why: Brake rotors are designed with specific measurements and tolerances. When rotors get worn out, they lose thickness which is an important factor for safe braking. With out the ability to quickly dissipate heat from friction, other brake system components can be effected by heat. Rotors can also get corroded which wears down brake pads quickly. With new rotors, you will feel increased braking performance and stability.

Battery terminal service
Vehicle batteries provide energy to start the engine, and supply power to accessories when the engine isn’t running. But both the cold of winter and the summer heat can place a heavy demand on auto batteries.
Why: Every time you drive while your battery is past its prime, it is a risk at getting stranded. Your battery provides the power needed for the engine to get started and also provides power to all your accessories while the vehicle is powered off. Batteries are affected by weather as well. In colder weather, the oil in your car thickens and it takes a considerable amount of power to get your engine to turn over.

engine cooling system service
Engine coolant, also known as antifreeze, is a heat transfer fluid designed to remove excess heat from your engine. The coolant absorbs the heat from the engine and stops the engine water from boiling in the summer.
Why: The coolants primary purpose is to keep your engine cool. If your cooling system does work effectively, your engine can overheat. A coolant flush removes rust and scale deposits which build up over time. Additives in the coolant lubricate internal parts and have anti-corrosive properties to help keep components free from contaminants. Getting your coolant changed can help extend the life of the water pump, which can be costly to replace if damaged.

Fuel system service
Fuel injectors are crucial to the efficiency of how well your engine operates. When working correctly, they provide accurate amounts of fuel to the engine so that you get the performance you expect when stepping on the gas pedal.
Why: The flushing of your fuel system is to remove any deposits that may have settled in your fuel system over time. These deposits can reduce fuel flow, put extra stress on the fuel pumps and cause your fuel injectors to not deliver fuel properly to your engine causing problems. Symptoms of a vehicle that has problems with its fueling system can be seen as seeing a check engine light, reduced fuel efficiency, lack of engine power, running hard after starting and taking a long time to get the car started.

Differential fluid service
Just as you pay attention to the oil change for the engine, the differential needs that same attention. The differential in your vehicle needs to be working properly for longevity of your vehicle and safety.
Why: Lubricating fluid inside the differential transfers heat away from the gears, helping to preserve the life and performance of your differential. Over time though, operating temperatures and wear can cause the fluid to break down. When the fluid breaks down, becomes contaminated or leaks occur, the gears inside may not work smoothly because of increased friction and heat. If the gears start to grind, continued driving can cause costly repairs.

transmission fluid service
A transmission service is a factory recommended maintenance item, just like changing the oil or rotating the tires. It is something you should do while your transmission is working properly to avoid costly repairs down the road.
Why: Over time, your transmission fluid degrades and stops cleaning and protecting the hundreds of moving parts. You may notice unusual performance problems such as hard shifting, gears slipping, chattering or vibrations. There is a buildup of contaminants in your transmission that is flushed out and replaced with new premium transmission fluid which extends life of the unit.

air conditioning service (Cleaning & deodorizing)
Your air conditioner does more than just simply blow cold air into the vehicle cabin. It also works to remove the hot air from inside the vehicle. In the summer, having a working air conditioner system will help you keep comfortable while in traffic.
Why: In the summer you may have no cooling, which can lead to dangerous levels of heat in the cabin. In the winter, the AC can be used to remove humidity, which helps your windows defrost. Regular maintenance ensures that the compressor receives proper refrigerant and lubrication levels, which reduce the risk of compressor failure.
