Only place I let touch my truck... Great work and honest people Loren and his family run it.... They are knowledgeable about Fords (especially 6.0's) more than most in the are guaranteed... They work on all other major brands as well.... I recommend them highly for any work you need done to your diesel vehicle...

Jeremy is absolutely great to work with, appears very knowledgeable. Unfortunately he had to deal with my horrible warranty company. But i appreciate the patience hes given, treated us well from day one to the end.

When my 2005 E350 with the 6.0 began blowing white smoke from the exhaust, I knew it was finally time for the major repair visit I had anticipated since I purchased it four years ago. I did a lot of research before deciding on Diesel Tech because I wanted the job done right and from what I could tell, these guys really know Powerstroke motors. I dropped the van off prepared for the worst (thinking maybe blown head gaskets, new studs, etc.), but the diagnosis came back as a bad injector. I asked them to go through everything they could think of to make the van as reliable as possible since I use it for camping in very remote off-road locations (it's a 4x4 Sportsmobile camper) and I suggested many potential items for upgrade or replacement. They listened to my suggestions and explained clearly which were good ideas, which were not necessary and most importantly, why. They actually talked me out of spending more money than I needed to while still making me feel very confident the van would be as reliable as can be. Since picking it back up a few weeks ago, the van has been to the middle of nowhere and back ...and is running as good as ever. Great job guys! I'll definitely be back for any future needs.

The most professional auto repair shop I have ever been to. Built on repairing the engine deficiencies of the PSD 6.0. Just check them out in person, heavy duty diesel trucks stacked up ready for Bullet Proofing.

Brought my 1995 dodge cummins in, they did an amazing job putting new injectors in, new vacuum lines, transmission lines. I would definitely recommend, they were on time and communicative, got under my truck today and noticed they took time to reroute everything nice and neat, even made some mounting brackets for the lines

Great honest guys who fix your problems quickly and do not try to take advantage of you like most mechanics! It’s really hard to find an honest mechanic. I definitely will be taking my duramax truck here from now on.

Took my 2005 Dodge ram with a Cummins to diesel tech for repair of an engine light. The truck was repaired promptly and Michael was very professional. Great communication as well

Credibility & Honesty passion for perfection but the humbleness to understand each and every customers needs and budget. There are not enough words for me to explain my gratitude to the entire crew at Diesel Tech for quality of service and their attention to detail on every truck I bring them. Thank You!

Super nice staff. Don't want to throw parts at the truck, if they aren't sure it going to fix it.

My husband Larry and I have been taking our 2004 F350 Diesel to Diesel Tech for a number of years. We have always found Diesel Tech has been more than fair with us. They have fixed any problems we brought to them, advised when we should think about buying a new truck. They are fair, honest and do a fantastic job when repairing your truck. We highly recommend Diesel Tech. There are other shops out there but no one as honest, fair and forthcoming as Diesel Tech. We are beyond pleased with our experience!

Absolutely the best!!! First had them check out my 7.3L a year ago after I bought it. They gave me a list of immediate fixes, a to-do list in order of priority, and then improvements that were/are targeted towards my goals with the truck. Then yesterday (a Friday), Lorne went out of his way and stayed after hours to ensure that I received the parts I needed. I plan on bringing the truck in there for the trans cooler upgrade as well as ALL my future work. Great guys, great work, and unbeatable service. Update: Is brought the truck back in (05/2021) because it was in an accident and I wanted the whole thing checked out. They did a full write up told me what was wrong/broken, what was going out, and what was getting worn out and when to fix it all. Once again the customer service is amazing and communication was consistent. Thanks guys! Only place I'll take my Diesel.

The only place I will let work on my truck. After going to 2 different shops in the corona/norco area these guys are the most trustworthy shop. They are honest and get the job done. They are worth the drive. My 6.0 runs better now than when it was new. Thanks Michael and Loren

If you need your diesel fixed, and fixed correctly, and you want to pay a reasonable price, these are the guys to see. Family owned and operated, truly great people to work with. Educated so they know what you're talking about, and know what they are talking about.

Took my F-350 Dually in to get a leaking radiator hose installed. They did an excellent job and the price was very fair. Unless you’re getting warranty work done I’d take it here.

I stopped by the Diesel Tech booth at the Sand Sports show and described an issue I was having with my 7.3 Powerstroke. Michael was very knowledgeable and informative. A few days later I visited the shop and the issue was exactly what Michael thought it was and they took care of it. Class act shop! I will definitely patronize this business.

I ordered some parts from Diesel Tech that, due to supply issues from the manufacturer, had a lengthy lead time with an unknown ETA. I worked with Jeremy and from the very beginning he informed me of the supply issue and offered to cancel my order if I would like. As Diesel Tech offered the best deal around and since no one else could provide the part either I kept my order placed. During the whole correspondence Jeremy was very transparent and kept me in the loop. I did think about canceling the order a few times (not their fault as this was a manufacturer supply issue), but given Jeremy's transparency and updates I decided to keep the order placed. Given that the reason for the holdup was on the manufacturer's side and that Diesel Tech provided upfront and clear communication the entire time and provided me with options I'd give them 5 stars and would absolutely do business with them again. Supply issues can affect everyone, but good communication on Diesel Tech's part left me well informed to make a good decision.
