Your Flathead Valley Mechanic: Shop & Mobile Repair

C.A.S. Repair provides Flathead Valley with expert auto care, from routine upkeep to total engine rebuilds. We offer:

General Auto Repair

Everyday repairs for cars, trucks and SUVs. We find the problem, explain it in plain language, and fix it right the first time.

A check engine light doesn't have to mean guesswork. We use scan tools and hands-on testing to find the real cause, not just clear the code.

Pads, rotors, calipers, shocks, struts, ball joints and tie rods. Everything that keeps your vehicle stopping safely and driving smoothly.

From oil leaks and misfires to timing components and major engine work, we handle repairs big and small.

Batteries, alternators, starters, wiring and lighting. We track down electrical problems and get you starting reliably again.

Oil changes, tune-ups, fluids, filters and cold-weather checks to keep your vehicle dependable through Montana winters.

Diesel engines, 4WD systems, drivetrain and heavy-duty truck repair for the vehicles that work as hard as you do.

Work trucks and farm, ranch and fleet vehicles kept on the job with less downtime.

Buying a used vehicle? We'll give it a thorough inspection before you buy, so you know exactly what you're getting.
