Frequently asked questions

If it's a car, we'll fix it. If it's a question, we'll answer it.

Is the cost of diagnostics included in the overall repair service?

Diagnostics is a separate service as it involves specialized tools, expertise and time. Once diagnostics are completed, our friendly service writers will discuss recommended repairs and associated costs with you before proceeding with any services.

What services are included in an engine tune-up?

You may have heard several different definitions of a "tune up." Typically, our engine tune ups include checking, diagnosing and replacing spark plugs and any necessary engine wiring. However, we offer comprehensive diagnostics and mechanical services to take care of any issues you may be experiencing.

How often should I get an engine tune-up?

Frequency recommendations for engine tune-ups depend on the vehicle. Reference your vehicle manufacturer's recommendations. Regular tune-ups help maintain optimal engine efficiency.

Can I prevent engine electrical system issues through maintenance?

Regular maintenance, such as battery checks, alternator tests, and electrical system inspections, can help identify potential issues early and prevent breakdowns.

What does an alternator do, and how do I know if it's failing?

The alternator generates electricity to charge the battery and power the vehicle's electrical systems. Signs you may have an alternator failure include trouble starting your vehicle, dim lights, battery warning light, and low battery levels. Our certified technicians can help accurately diagnose if there is an issue with your alternator or another component of your vehicle.

Can a failing battery affect other engine electrical components?

Yes, a failing battery can impact the entire engine electrical system, as other components rely on the battery to start and provide power.

What does it mean if my "check engine" or "service engine soon" light comes on?

There are many electronic components and sensors that manage your vehicle's emissions and performance. When one of these fails, the "check engine" light or "CEL" is illuminated (commonly yellow) on your dashboard. Although your car may seem to run or drive fine, it is important to have the issue addressed to prevent damage from occurring. There are times when a check engine light is a simple fix, and others where it is a much more serious problem.
