What does the "check engine" light mean?

There are numerous sensors and electronic components which regulate your vehicle’s engine performance and emissions. When any of these fail, the “check engine” light illuminates. Even though your car may appear to run fine, it’s crucial to have the issue resolved to prevent long-term trouble.

What should I do if my car starts to overheat?

This is a very serious problem – if your car overheats for too long, you can destroy your engine. As soon as possible, find a safe and secure place to pull off the road and turn the engine off! Don’t attempt to examine the fluid level in the radiator; the hot fluid can result in serious burns. The best thing to do is have your vehicle towed to Walt’s Auto.

Does where I get my vehicle serviced matter?

Yes. A professional, certified auto mechanic is required to pass through continual training in the latest systems and adept use of state-of-the-art equipment in order to check the electronic devices which control most cars’ functionality and to enable diagnosis and prognoses of complex issues. Equipment includes: electronic scopes to monitor sensor alerts, scanners to communicate with the computer systems, etc.

Also, a licensed and certified auto mechanic has access to tech-info solutions to reference wiring diagrams, manufacturer’s technical service notices and other data. Without these resources, a garage auto technician could easily misdiagnose your vehicle’s problem at your expense.

How can I keep my vehicle's warranty in effect?

Ensure that your car or truck is serviced at the regular intervals designated in your Owner’s Manual or Warranty Booklet, and keep precise records of your vehicle’s routine maintenance. Be sure to list the date, parts installed, vehicle identification number and mileage documented on the invoice. Keep these receipts in a safe and secure place. If you have a service log in your Owner’s Manual or Warranty Booklet, make use of it. For recommendations on service intervals, check out our Preventive Maintenance schedule.

Am I required to use my dealer for maintenance?

No. You may have routine servicing done by any independent service station, shop, or garage and still uphold your warranty.
