Orange CA Diesel Repair

I have a Fleet of Trucks , Donnie & his Team are straight up professionals, fair & honest!!

Great service priced right (probably 20 - 30% less than the dealership with better quality skilled tech's that know what they are doing). I want to keep my GMC " LBZ " going forever because a new diesel truck cost $ 85,000 + and they AINT NO BETTER than an LBZ Duramax

great work good people truck rides very nice thanks you have a new and happy customer

I went to this shop based off of Google reviews and was very impressed with the service. Donny and his crew helped me out with my Ram 2500 Cummins. I took in for an oil change and front end service and was very happy with the results and happy they were able to fix a few other issues that I probably would have left unattended until it was too late. Him and his crew are very knowledgeable and treat you like a best friend. If I'm ever in southern California again this will definitely be the only place I bring my truck.

Took my truck there to get it fixed and now I will never take it anywhere else.

When I started looking around for a repair shop to make several badly needed repairs I did not know where to start. I did speak with a couple Dodge dealerships, they informed me my truck is to old and no longer have repair manuals and are very limited to servicing my 2001 Dodge. I searched the internet for local diesel truck repair shops and found ABCO Diesel. To date ABCO Diesel have conducted several needed repairs, full rebuild of my 6-speed manual transmission, drive shaft, brake system, steering box and front suspension work. I am very satisfied with there work. ABCO Diesel has a great operation, customer service was great. I would recommend this diesel repair shop to anyone that has a older diesel truck.

One of my neighbors asked me if I knew any diesel mechanic for a second opinion, so I searched online and Abco Diesel popped up, I gave my neighbor their number, few days went by and I saw my neighbor again and asked him about his experience with Abco Diesel, he said the first shop ( Greg at G&M Diesel now All American Diesel) had quoted him an outrageous price for some minor repairs, and Donnie was able to do the repairs for a tenth of the price and in only 1 day, Greg at G&M Diesel wanted to keep the truck for 1 week, anyway I want to thank Donnie for taking care of my friend and neighbor, 5 stars to you bud!!

Our favorite diesel mechanic in Orange, CA found 2 of 3 parts locally and we drove to Santa Clarita to pick up another part. Home by 1:00 PM and Donny at ABCO Diesel finished the repairs by 3:00. He’s a Diesel Angel from Diesel Heaven. He saved our bacon going to Georgia and saved it again going to Idaho. And all of this after the dealer told us that there were no pairs available in the entire country and they had no idea when they would get them. We were looking at a completely ruined caravan. Thank you, Donny. We canceled three nights of campsites in anticipation of not being able to get to the caravan. After repairs we started towards Las Vegas at 5:00 PM, called ahead to Vegas/Ely, Nevada/Twin Falls, Idaho and all the campgrounds reinstate our reservations at no additional charges. The nightmare trip turned into a totally joyous event. So here we are in Twin Falls ready to make our last leg into Boise, Idaho today to begin our 70-day caravan tomorrow.
