Ron’s Diesel Repair Shop

Best diesel shop in town hands down. I had my 2006 ford f250 worked on at 2 different shops and they could not figure what was wrong. I took it to Ronny and within a few days he had found the problem. He explained everything in detail and even offered to give me a ride. Excellent customer service, very honest and knowledgeable. I would recommend to anyone who has a diesel truck.

Ronnie is extremely fair in his prices, he's completely trustworthy, he always explains exactly what needs to be done and why, he shows you the parts he took off and gives you options. I love this brother & highly recommend his shop.

Ronnie was the point of contact. After having the 03 Chevy duramax 2500 towed there because it started to throw white smoke out of the exhaust. Ronnie ran multiple tests which I already had an idea that it was the injectors. We went ahead and upgraded the fan clutch and radiator, replaced the water pump, did the injectors and injector cups, gaskets, o rings, thermostats, and hoses. It took almost two weeks because one of his mechanics got into a bad accident and was going to be off for a week. But he called and explained this to me and even after parts had been ordered didn’t expect me to stay because of the delay. He was a little pricey but the work was good and two days after picking up the truck we hauled our 14K pound trailer to pismo and had no issues and more power after the repairs. We definitely be back for future repairs on all our vehicles!!!

Ronny was a lifesaver! Our water pump locked up and threw off the serpentine belt on our Cummins Turbo Diesel. We lost our power steering, power brakes and coolant was leaking out of the cracked water pump. We were traveling home on the 99 and broke down in Madera. I was looking for a certified diesel mechanic and Ronny took my call before 8 a.m. the next day. He stayed late working on our truck and we were on our way home the same day! He was thorough and personally road tested our truck to make sure everything was right. He is a super nice person and very conscientious. Ronny is one of the good ones!

Went there to get my mustang fixed and smogged. My car has plenty of problems wrong with it and was expecting to pay upwards to $2500. Got my car fixed and smogged for $1050. Talk about a STEAL! This place is honest and will make sure to have your car running how you want it. 10/10 would recommend to my family.

Owner is unprofessional, let my vehicle get impounded because owner decided not to pull it into the shop. Owner sits on his phone while customers are waiting. My truck had two brand new batteries and I had an excuse three days in a row that they were dead.
