Colby and his team are FANTASTIC. I called after making the mistake of putting DEF into our diesel truck's gas tank. Instead of laughing at my mistake or making me feel worse, he walked me through the options and possible outcomes. We had the truck towed to the shop and Canyon kept us updated every step of the way. The repair was not cheap, but it also was not as costly as I was afraid of. They had to put alot of time and work into getting it back up and running, but I am happy to report that several thousand miles and a few months later the truck is still running smoothly. I highly recommend Colby's Diesel Shop for your diesel repair needs. Thanks!

If you’re looking for a great diesel mechanic in the area, Colby is your guy. I am a full time RV’er and needed an oil change on my Ford F350. While talking to Colby, I mentioned I had a small oil leak from the pan and how much Ford wanted to reseal the pan. In our talks, I could tell Colby knew his stuff and he offered to reseal the pan for significantly less. It’s been about 5k miles towing my 17,000 LBS RV over some big mountain passes since he resealed the pan and I have not seen a drip of oil since. I would highly recommend using Colby for any diesel repair needs you may have. He’s honest, trustworthy, knows his stuff, and has really fair prices. 10/10!

This Diesel and Automotive repair shop was a fraud. Please be aware when taking your vehicles to this shop because he will try to get money out of you. This review doesn't even deserve a one star.

My GMC diesel van broke down on Memorial Day as we were driving through Utah. Lucky for me, Colby and Kenyon were working on the holiday and could help me! The issue was a tricky, random electrical issue, which they found after meticulously evaluating my engine over about 12 hours in total! They fixed the problem, and my van has since driven to Texas and back (from California)!
I was so grateful that Colby and Kenyon 1) were working on a holiday!!!!! 2) were super friendly, and explained everything they were doing clearly and succinctly 3) the cost was super-reasonable 4) they used their care and skill to diagnose my weird engine issue and get me safely on my way!
Thanks again!!!!!!!

Needed a sensor replaced on my truck quickly.
Colby was able to diagnose, install and perform all tests in one day.
And the price of the part and labor was reasonable.
He kept me informed of every step.
Highly recommend this shop for diesel work.

Colby diesel is the best, Ford dealer wanted to charge me $6000 for repairs. Colby charged me less than 1/6 of that including added repairs. I will go to Colby for all future repairs and you should to! Thanks Colby!!

There really should be more than 5 stars and Colby deserves them all. After breaking down with a new-to-me skoolie, he saved the day. Not only did he fix the bus, he was thoughtful and caring with my situation. He is trustworthy, reliable and professional. I would drive hours to have him work on my vehicle. Thank you so much Colby & family! You truly have a place in my heart and happy to call you guys friends! ?❤️

Took my 6.7 in for a diagnostics and they told me it needed an Injector. Had the injector replaced & the truck was having the same issue. Was then told it needed 4 new injectors so had him replace all for new ones. After 7k of repairs the problem was still not fixed. Decided to take my truck in to another mechanic and had it diagnosed again but this time it came back for a lifter job and cam. Explained to my new mechanic what had gotten done and he explained to me that there was no reason for the injectors to be replaced for the issue it was doing and that any good mechanic should have been able to diagnose it the first time for lifters and cam. Finally had the right job done and now my truck is fixed and running great. Would not recommend to go here unless you want to pay money for no reason!

I don’t usually post “Google Reviews”. Colby and his team are outstanding! We broke down south of St. George on our way home to Canada while hauling cattle. He replaced all the injectors in our truck and had us on the road in less than 24hrs. Wouldn’t use anyone else in that area.
