Took my 2003 Dodge Ram 2500 5.9L in for a Turbo replacement. Noe and his team did a fantastic job. Fast turn. Great communication throughout the process.Thanks for making my truck great again!

Person driving your semi tried to run me over. Trucks clearly too tall with too big of a grill for their short self to see over.Dont drive a uselessly large truck if you cant see over the dash.

Called mid morning to schedule an alignment and they brought me in Even though they closed at 5 they stayed after 6 to finish it which I’m greatly thankful as it’s my only vehicle. Truck drives straight and steering wheel is straight. Great communication and great work. Thank you!

Brought my 2005 dodge ram in because I needed my Airdog 2 4G lift pump installed. not only did Noe get it done same day but he stayed until 7pm on a Friday just to get what he promised done for me. he was half the price of other OC Diesel shops, and did the same quality of work. I work in the automotive industry and can see that this shop goes above and beyond for their customers and is very knowledgable when it comes to doing regular service on your diesel all the way to doing aftermarket and performance modifications. Thank you Noe.

Dont bother them they have more important things to do!!!

I get all my work done here.

One of the best road and shop services Ive used in my 23 years of driving and owning trucks. Fair price, did the job quick. Estimate was a little less than promised and communicated every step of the way.Stonewall Motors IncSteve Elliott

WHAT A NIGHTMARE | NO, Im not talking about Orange County Diesel... Im talking about the job that I needed done on my Hummer H1. Took it to Noe (owner) at OC Diesel for a new set of fuel injectors and to install a new turbo that I bought elsewhere. He gave me a price and got to work on it within 20 minutes. Then we found out about three broken and missing studs on each exhaust manifold, broken/missing bolt on the starter, and a few other great surprises. There is just about NO work room on a Hummer, not to mention getting the broken bolts out. His employee worked on this thing for days... being very careful not to strip out my engine heads or have to use hela-coils.FINAL OUTCOME? Well they got her finished and the thing runs like new again. I could not be happier.YES I am a real person. My name is Keith and I am the owner of Orange County Construction and I will be trusting OC Diesel again with any of my repairs. The owner (Noe) is a man of his word!

Very honest and trustworthy. I bring my 1 ton duramax for everything.

Still waiting for my truck to be repaired, they ordered the correct part for a CA. vehicle but it isnt a CA vehicle as emissions go. Didnt check ahead of ordering. Now cost more money in alternate transportation, costly

I have taken my International Scout there twice now, and been really happy with it. Ruben in the back is awesome, great guy, straight forward, honest and no BS. The Diesel Scout is old, and I just needed to get it street worthy on a tight budget. The specialist Scout shop down the road claimed it would cost be 10s of thousands, and Ruben is in a few hundred without taking me for a ride. I had to source some of the parts myself, but that is what the internet is for. We were lucky that we didnt need a differential rebuild, just oil. Ruben and Noe stayed positive and was willing to try a simple solutions before throwing new parts at the problem. My only gripe (not worth a star) is that my initial inspection took a week not a day or two, but Noe called unprompted to let me know the delay.

Spent 10 mins on the phone with them on hold, they picked up the phone rudely asking me to stay on hold until they hung up the line. If I cant call and ask about a service for my truck I can see them doing well at any service. Hard pass.

Definitely thee place to take anything with a diesel motor that needs to be serviced!

I have been doing business with OC Diesel for years. They have always done a great job on my commercial fleet and I would highly recommend them.

Just started working in the area and needed a new mechanic. Told them an ongoing issue I was having with the exhaust system. I figured with their huge upfront inspection fee means they will solve the problem rather than patch it up. They tried to charge me over $200 more than originally stated for removing some hardware and soaking it in solution. I insisted I pay what was agreed upon before hand and he said he doesnt recall but will honor it. I was still noticing a major noise issue with the exhaust after I left. When I emailed them afterwards to say Id like to have them give a listen, the coordinator said I could come take him and a technician on a ride. Sounds great, I thought! That was an empty promise. They never responded to my multiple emails in the days afterwards trying to set up a meeting. The way the place is set up is not what you want out of an auto repair and service business. It is huge and they need a receptionist who cant give you good information so you have to wait for the coordinator who only seems to know the generalities of the problem Im having. Certainly not a place you can stop-by and ask a question or grab their attention, let alone get them to come on a ride. Over priced and impersonal. A few weeks later I brought it to another mechanic and they confirmed that OC Diesel did not, in fact, solve my problem.

I took my 2006 lbz duramax for a issue with it running super rough i spoke them over the phone to take a look at the truck i had AAA tow the truck to the shop and all the fun began the first day they never looked at it cause the truck came in around 2 ish. i understand that no big deal the following day i call around 1130 to find out an update on the truck. the girl said the guy was busy with a customer. i thought ok no problem an hour and a half went by no call so i called back i was finally able to get him on the phone and his attitude was like why in the hell are you calling me I will call you when i have something to tell you. that did not sit well with me so at the end of the day he calles me saying i have bad injectors on the truck and it would cost me $6100 im like your out of your mind the most expensive injectors out their cost like 4 grand and 2 grand to install them i dont think so i had the truck towed to another diesel show who did the job for 2 grand less. and might i throw out their they charged me to figure out the problem 300 bucks, straight highway robbery. not only was their customer service bad but their pricing is just nuts ill never even think to call or go back again i would recommend Buds diesel or Power house diesel
