Getting to the root of the problem

Accurate diagnostics before any repair

Automotive diagnostics is the process of identifying exactly what’s wrong with your vehicle before any repair work begins. It’s a crucial first step that helps avoid unnecessary parts, labor, and guesswork.
Many major vehicle repairs can be avoided entirely with correct diagnostics from honest, qualified technicians. Using advanced diagnostic technology, our team can pinpoint everything from engine and transmission issues to electrical and sensor problems with precision.
At West Side Tire & Auto and Cliff’s Tire & Battery, accurate diagnostics are at the core of how we work. It’s our mission to fix the problem correctly the first time, in the most cost-effective way possible.

Signs to watch for

Does your vehicle need a diagnostic check?

01 Check engine light is on

A check engine light is your vehicle’s way of signaling an issue that needs investigation.

02 Unexplained performance changes

Sluggish acceleration, rough idling, or stalling can point to an underlying issue worth diagnosing.

03 Unusual noises or smells

Unfamiliar sounds or odors are often early signs of a problem that diagnostics can identify.

04 Warning lights or error codes

Multiple dashboard alerts or recurring error codes call for a thorough diagnostic evaluation.

I have been using West Side for over15 years. West Side provides superior quality service, competitive pricing, and they always deal with you fairly. They have never failed to do exactly what I needed done with my vehicles without always trying to upsale me on stuff I didn’t need. West Side provides the best service of any shop I have used in over 45 years of owning cars and trucks. I count on West Side, you can too.

Have trusted them with multiple vehicles for years, they do a great inspection and tell you if something is starting to go wrong before it gets to be a major mechanical problem.
