Oil and Oil Filter Service
Experts recommend changing the oil and oil filter in your vehicle every 3 months or 3,000 miles, whichever is first. It’s an essential way to maximize engine protection.

Cooling System Service
Our team will flush the cooling system, conduct a pressure test, check hoses and cap and check connections.

Air Conditioning Service
One of our trained air conditioning specialists will inspect your car’s air conditioner, all A/C lines, evaporator and compressor for leaks and wear.

Driveline Service
We will remove old worn-out gear oil from the front and rear differential and transfer case.

Fuel/Air Induction Cleanup
Using specialized equipment, our technicians will quickly and effectively clean intake manifolds, ports, intake valves and combustion chambers and install injector cleaning additives in tanks. This service will restore lost power and performance and will reduce harmful exhaust emissions.

Power Steering Flush
Our technicians use a powerful cleaner to dissolve gum and varnish in your car’s power steering unit. Next, we will flush old, worn-out contaminated fluid and install fresh new fluid fortified with a special antioxidant and anti-wear ingredients to prevent expensive mechanical failure.
