How much is a good mechanic (technician) worth?

How many people do you know who trust the place where they take their car for service? Not that many? Well, Auto Care Plus is changing that.

Because the auto industry is constantly changing, Auto Care Plus continually invests in the latest technology and state-of-the-art equipment. Hi-tech cars also require highly skilled technicians. That’s why you’ll find an ASE-certified technician under the hood of your car at Auto Care Plus. We refer to them as technicians, not mechanics, and we’ve made the investment in recruiting and training the best technicians possible to work on your car.

Why is our service better?

We believe a happy customer is our best advertising. It’s not rocket science; if you just work on hiring good solid people, if you’re friendly, honest and turn out quality work, everything else takes care of itself. At Auto Care Plus you’ll always be greeted by a clean, knowledgeable attendant ready to make your experience as pleasant as possible.

Our Auto Repair Services

Below are some of the many auto repair services that we offer:

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. Oil changes at 7,500 miles are usually too long an interval for most common driving conditions.

Cooling System Service

Flush cooling system, pressure test, check hoses, cap and check connection.

Air Conditioning Service

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

Driveline Service

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 manifold, ports, intake valves, and combustion chamber. Install injector cleaning additive in tank. 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.
