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.

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

 Trustindex verifies that the original source of the review is Google. I had an issue with my truck on Wednesday night. The fan would keep running for like 10 minutes after I took the key out of the ignition. I looked it up and learned what it could be and how much the repair might cost. I also learned that it wouldn’t be wise to drive it around much. On Thursday morning, I called West Side Tire and Auto and explained what was happening. I also told them that I was supposed to travel out of town on Friday. They said they would try to fit me in if I dropped the truck off. I dropped the truck off at 1:30. They told me what was wrong at 2:30, then had it fixed by 4:15. They certainly didn’t have to do that. The problem was what Google said it could be, and the repair cost was less than what Google said it could cost. I am very happy with their customer service and the work they do.
