Air Conditioning Service

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

Cooling System Service

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

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.

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.

Power Steering Flush

Our technicians use a powerful cleaner to dissolve gum and varnish in your truck’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.
