For Everything Your Vehicle Needs!


A quality mechanic is more than just his or her automotive skills and training, but we’re also good at customer service. When you visit Sinclair’s Auto Clinic you’ll see us treat our customers and their vehicles like our own–like family. As soon as you realize your car needs special attention, you can rest assured that you already know a good clinic to take care of them. We like putting our customers on a routine maintenance schedule because that’s the best way to keep them on the road. Proper and thorough vehicle maintenance will extend the life, and your enjoyment, of your vehicle. Call us today, to schedule your next oil change, tire rotation, transmission repair or any other maintenance your car currently needs. Seasonal changes can catch you unprepared when your vehicle’s heating and air conditioning system is not working properly. Changes in weather will also have an effect on tires. Sinclair’s Auto Clinic is here to provide excellent tire maintenance and repairs.

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.

Transmission Service
Using the latest in state-of-the-art technology, we will install a safe and effective cleaner to suspend harmful varnish and sludge from the transmission valve body, torque converter and lines and install new high-tech fluid with conditioners.
