About the business
Black Diamond Diesel
& Auto Repair
Black Diamond Diesel & Auto Repair is a mobile mechanic service based in Blackfoot, Idaho, serving customers across eastern Idaho. We bring the shop to you — whether your truck is parked at home, your car won't start at work, or your equipment is down on the job site, we show up with the tools and the know-how to get it running again.
We work on diesel trucks, gas cars and SUVs, and heavy equipment. From oil leaks and dead batteries to injectors, head gaskets, cooling systems, and drivetrain work, most jobs get done right where the vehicle sits. No tow bill, no waiting on a bay to open, no shop hours that don't match yours. We work weekends too.
We're a small family operation. That means when you call, you're talking to the people who turn the wrenches — not a service writer reading off a screen. We tell you what's wrong, what it'll take to fix it, and what it costs, in plain language. No mystery charges, no upsells you didn't ask for.
If you're in Blackfoot, Idaho Falls, Pocatello, Shelley, Firth, or anywhere in between and you need a mechanic who comes to you, call (208) 534-8792. Se habla español.
What customers say
"Honest and fast. They told me exactly what was wrong with my Silverado and what it would cost before they started. No surprises on the bill."
"Our backhoe was down on the job site and we were losing money every day it sat. They came out on a Saturday and got the cooling system sorted. Lifesavers."
"My Ford F-250 wouldn't start in my driveway. Called Black Diamond and they came out the same afternoon, diagnosed a bad injector, and had it running before dinner. No tow, no hassle."
