Adrian mechanic is the best mechanic I’ve ever met. He is very professional. Excellent service. Honest, and always willing to explain anything related to the truck he’s working on. He’s ready to give both explanations and suggestions. I’m truly impressed and wish him all the best. I’m delighted with his work and I gladly recommend him to anyone who finds themselves near his shop — you shouldn’t have any doubts, just go to him. He is a top-quality truck mechanic.

Our RV was having issues accelerating and I found this listing online. It was the closest diesel shop so we stopped in without an appointment. Adrian stopped what he was working on and diagnosed the issue and got the parts we needed so that we could get back on the road. He showed us the diagnosis codes and explained what he thought was going on. The problem was fixed a few hours later for a reasonable price. I highly recommend Reliable Diesel Repair.

The best mechanic in Arizona for me. A professional, skilled, and reliable person you can trust. 1000% recommended. Expert in Cummins, Detroit, and Caterpillar.
