Colby's Diesel & Automotive Repair

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!

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... read full review
