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.
