These guys are the best! I took my truck in for a heater core. They did the work and the truck smelled like coolant bad and after the heater core replacement my thermostat was not working right. They had me bring it back and ended up doing a coolant flush and replacing the thermostat with no extra charge to me. I can't tell you how thankful I am that they did this after paying over $760 for the heater core! Really awesome guys and gals over there! They're my go-to repair shop now for sure!

Great.

Phenomenal crew!

These guys are phenomenal! Had them install a transfer case for me and an electrical clip break off after I left their shop. I went back and they found the problem and fixed it right away! Keep it up y'all! - Kevin J. (5 star review on Google)

Good all around!

Traveling through on my way to West coast with a horse trailer at a AC compressor go bad. I called in to Mr. Diesel, and they got me in right away. Very nice job--thank you for getting me in and short notice and back on the road. These are very nice people to work with. Good prices, good people, and well knowledged. - Lee D.

2012 GMC Denali 2500HD - Had to have the transmission rebuilt. After I got truck looked at, I thought it was a quick service and the parts recommended was spot on. This rebuild also included a lifetime warranty, so how can you go wrong with that. Customer service was also great, mechanic followed up asking how truck was running!
