Great shop and super knowledgable. If you need diesel work in the area, I would give them a call.

This is a great business run by a family that is committed to taking great care of their customers. I brought them a 20 year old truck with an electrical problem. Most mechanics would have run away. The folks of Diesel Tech dug in and took the time to give me the reliable truck that I need. Thank you! Their price was fantastic and you can't argue with results. read more

These guys are THE BEST. I've had my Super Duty worked on here three different times. They are by far the best repair shop I've ever found. They are trustworthy, honest, knowledgeable and reasonable. Look nowhere else. read more

This the first time I have used Diesel Tech to address a black smoking issue with my 6.0. I was dealing with another diesel shop in Riverside and found their approach to addressing the issue as a "lets try this next" attitude with no structured diagnosis of the problem. When I dropped my truck off at Diesel Tech they were very clear on what they would be checking by following Ford's recommended procedures for diagnosing the problem. After spending more than 2 hours working on the truck they thought they found the problem, a bent terminal on the turbo's VGT connector. We road tested the truck and it seemed to solve the smoking issue. However, after driving it for about 30 miles the smoking started again. I called Diesel Tech and Mike was very accommodating and said they would work me in to their schedule to further address the issue. Excellent customer Service. I'm sure I will be writing a very positive review once they fix the problem next week. read more

Great service best service anywhere 100% happy I recommend them highly truck runs great

Cant say enough great things about this shop . Loren and Mike and the whole crew are top notch . Ive brought 3 different trucks to these guys over the years and they always exceed my expectations . This last trip to them they removed my beat down 4R100 transmission .. completely rebuilt it , beefed it up , and addressed a laundry list of issues my 7.3 had . Every part is OEM quality . Not one thing was overlooked . They walked me through step by step what was involved and delivered on time , as promised . I live 2 hours away .. and gladly make the trek to them for all my diesel needs because i trust this shop . They are genuinely great people .. and when i go there they treat me like family . Dont settle .. go to diesel tech ! You wont be disappointed or regret it ! A+ ! read more

Came in here to get my 6.0 bulletproofed and the process was quick and painless. I was given a date for my truck to be finished and it was delivered a few days before. If you want quick cheap work don't come here you get what you pay for. Michael was transparent with me throughout the process and kept me updated on what was going on. Recommend this shop if you are looking for any diesel work they went above and beyond. read more

Lauren and his crew at Diesel tech are amazing. I have owned multiple power stroke diesels and will Only let Diesel tech work on them. read more

I took my 2016 Ford F-350 to a different shop in town and they were unable to definitively diagnose the problem. Since they weren't 100% sure what the issue was I decided to get a second opinion. When I called here they told me what it most likely was before I even brought it in. I took it in and they had it diagnosed and repaired very quickly. I will definitely be back here in the future. read more

We wet to this location because it was referred to us by a friend. I have 2004 chevy diesel with injectors problems, however We spent little over 8k in total to fix our truck. It started off by the truck needing injectors, from here it just went to crap. The truck has water in the oil, low oil pressure,low coolant I took it back several times they say it's fine.They strongly misdiagnosed. All they say is "well, it could be"... we pay for the "it could be " it turns out worse. This place left me with a sour taste in my mouth, heavily dissatisfied and disappointed. I could go into more detail about how they brush you off when you comeback with your truck being worse than when you first took it there. Now the truck is just sitting collecting dust. 8k later Broken down!!! I strongly Do Not Recommend!. read more

I had my F350 towed to Diesel Tech with what turned out to be a turbo issue. They explained to me the problem, what it would cost to repair and had my truck ready when promised. Absolutely would recommend and take my truck to these fine gentlemen. read more

WOW, WOW, WOW!! In today's world it seems like customer service has gone away but not here!! Loren the owner and Michael are class A at attention to detail. Their mechanics are awesome at diagnosing the problems. They are thorough and explain what they think you should do, they also let you know what is wrong but can wait if need be. I took a recommendation from a friend and had the vehicle towed from the San Diego area. They have exceeded expectations and they will be our go to mechanics from now on. Thanks Loren, Michael and staff!!!! read more

I have a dodge 3500 mega cab Dually with a Cummins 6.7 and I always bring it to Diesel Tech. The staff there are great they're very quick on repairs and always extremely helpful... 10 thumbs up!!! read more

This is my 3rd visit to DT. I could have sworn I left a 5 Star Review after my first trip there last year, but in looking into things I discovered that I did not. So this review is based on 3 visits to this great shop. We have a 2003 Ford F350 6.0L PowerStroke. We all know about these engines. The guys here at Diesel Tech are maestros when it comes to working on these particular engines. They installed a Sinister Diesel Blue Spring unit, and a Sinister Diesel Coolant Filter Kit. Both jobs were done quickly and with a low labor quote. They are not the cheapest shop, but their prices are very fair and each time they have wrenched on my truck they came in on time and on budget. They are friendly to deal with, and I could not recommend this shop any more than I am. I will be back to this shop. Great experience!! read more

Ask what you diagnose fee is before you leave your truck. It can match the charge of the repair. Get it? They will charge you double and hold your vehicle hostage. ABSOLUTELY DO NOT RECOMMEND. YOU WILL SAVE MONEY TAKING IT TO THE DEALERSHIP read more

Diesel Tech did me right. As an owner of a 2006 F250 with a 6.0, the shops I allow to wrench on this truck are few and far between. They are about 75 miles from my house, but well worth the drive. Lauren & the team got my truck diagnosed quickly. The price was fair. The expertise and knowledge of the 6.0 is outstanding. Thanks guys. I'll be back! read more

The best diesel mechanics around the work speaks for itself, the price is affordable and fair also the best customer service I have ever had they care about there customers i absolutely recommend them read more

Great customer service & they explain what is needed to be done as well as there not pushy but give you the chance to do what you want or suggest this is my new Diesel mechanic Now read more

Recently had my oil change and fuel filter done on my 2014 Ford F-250. The technician indicated that my front brake pads needed to be replaced. I made an appointment to have my pads replaced and rotors turned. Dropped vehicle off at my scheduled time and received a call 4 hours later the job was completed. The reason I took my vehicle to Diesel Tech and not the Ford dealership is in the past the dealership seemed to upcharge me for things that did not need to be done. Diesel Tech does what needs to be done and they do it in a professional manner. They don't try to spend my money by doing things that are unnecessary. Thank you Loren, Michael and your entire staff. read more

After 1 independent mechanic and 3 Ford Dealership service centers, We will NEVER take our 2004 Eddie Bauer Excursion to anyone else EVER. Thet KNOW the Powerstroke engines, for all the good and bad, they KNOW. We bought the Excursion brand new, Nov. 2004 with 14 miles. Now with over 260,000 miles and 2 sets of all 8 fuel injectors, 1 by independent (later found only replace 2 URGH and replaced the computer because ge couldnt fet it running, but used a F-350 computer...) full 8 at Dealership, and another 4 eith Deisel Tech. The difference with Deisel Tech, in 24 hours, it was diagnosed, repair completed and back on the road with 24 hours!!! They know their $#*&...aka - Stuff! Our biggest regret, is not following our first instinct to take the Excursion to him 4 years ago when the injector nighmare began. Being woman, its always uneasy going to a mechanic shop. There are some that are just plain condescending, or you feel like you should have worn a body condom there and need a radio active exposure shower after you leave!! Not at Deisel Tech, very nice, relaxed and respectfull. They don't gouge, they understand that vehicle repairs are expensive, not judgements! They make suggestions, but don't make you feel like crap, cause you don't to do or don't have tome or $$ to do a suggested repair. Will only take our 'blue bus' to Deisel Tech. Thank you!!!! read more

I have used Diesel Tech for 10 years and have had nothing but the best service from them. They are very knowledgeable and are always very reasonable with their pricing. read more

Thank you guys forgetting us back on the road! Got our truck back in less than 4 hours,

I would like to sincerely thank the Diesel Tech crew ..Being from Mississippi and not knowing anyone around here this crew was awesome to work with. Fair and honest and really patient as I most likely will need a new engine and don't have time left here to get a new one installed they were super patient while it took me two weeks to get a auto carrier to take my truck back home. Thanks again everyone for all your help read more

The ONLY PLACE FOR YOUR DIESEL OR V10!!! I thought these guys only worked on Diesel but learned they could also help me with my Ford V10 Triton. Jeremy, Michael Loren and staff are extremely professional and take the time to walk you through every step of the way of your repairs. They give you options of must fixes, recommended fixes, and potential fixes. They worked on my 6.0 before and did a great job!! Now they are working on my V10 and again their Customer Service is NordstromLevel, Ritz Carlton Level, Ruth's Chris Level. Bottom Line you get what you pay for and I obviously keep going back!! read more

We drive all the way from Calimesa for them to service our F250, because these guys are so knowledgeable, honest and fair. While getting ready for a trip in March, we noticed a leak. After they checked it out, they told us that a part they had replaced for us in November was defective. They replaced the part, and didn't charge us anything! Not for the part or the labor! They could have told us it was something else entirely, or at the very least charged us for another part, but they were totally honest. It's so nice to know that there is a mechanic we can trust, who is always upfront with us! Thanks, Diesel Tech! read more

A horrible place to refer anybody to guy a joke and unprofessional as it gets good luck to anyone that chooses this garage to work on your vehicle over priced and dudes all over place ripoff artist in if your truck not a ford they don't take u serious read more

Absolutely the best place to bring your Ford Powerstroke! The service exceeds any dealership, and the price is far less than a dealership. This place was recommended to me by 2 Ford dealerships when I asked about repairs outside my warranty. My 6.0 has been dealer maintained since day one and Diesel Tech maintained since my warranty expired. I bring it in for scheduled maintenance and always get a great inspection prior to leaving; if something is a concern, the tech will actually show me what the concern is. Friendly service and able to answer any questions you have on your Powerstroke. Bring your rig here, everywhere else is bush league... read more

Found my problem the same day I dropped off my truck. Two Ford dealers in the last 5 years couldn't solve the bad O2 sensor. Fair pricing and great ppl. read more

Took my truck in beacuse of a diesel leak.well they found it and got ir fixed. I was charged reasonably.only reason giving 4 stars is because they arent open weekends and makes it hard to take or pick up seing as i dont get home till after they're closed read more

The only place my husband will take his Excursion. They know what they are doing. They've always been so very helpful. My husband is a Marine and with every duty station change in California, this is the only place he takes his vehicle. He will drive hours to take his vehicle here. Even when I call on my husband's behalf, they have been so very helpful and patient with me. We have first hand knowledge of how detailed their work is, how upfront they are about problems and how well they take care of our vehicle. We won't take it anywhere else. read more

PowerStroke Kings! My truck has not ran this good, even when it was new, it never ran cool when towing, Now after i had all the work done "Bulletproofing", I tow up to 8000ft above sea level with no problems, also doing this on a bi-weekly basis. So if you want a company that knows what they are doing this is the one! Thanks to the Staff. read more

I'm an out of towner, (work in the area during the week, go home on the weekends). Recently took my 2004 F350, 6.0 turbodiesel in for an oil change. Quick and and easy. Thanks fellas. After leaving their shop, I had an unrelated issue (to the oil change) while getting diesel fuel. The truck wouldn't go into gear. I called Michael at Diesel Tech and explained the situation. They sent a mechanic from their shop to my location and he crawled under, diagnosed and repaired the broken linkage on the spot. Wouldn't even accept any payment for the service call. That is going above and beyond that is rarely seen these days. Stellar group of guys. They're courteous, respectful and knowledgeable and they will certainly have my business in the future. FIVE STARS. read more

In a sea of overpriced diesel shops these guys are the best. Straight up and honest. It don't get any better than Diesel Tech ..... honest work at an affordable price. I won't take my truck anywhere else. read more

Great customer service, Loren and his team of mechanics are awesome and do a great job. I wouldn't trust my truck to be worked on by anyone else. read more

I here great things about the work done on everyone's powerstroke. But how about duramax?

They definitely know about diesel engines but they overcharged for everything. Also did testing without asking and now water pump is no good we will never use them again read more

If you own a Ford powerstroke diesel then this is the place you need to go for service, repairs, performance upgrades, etc. I recently had my 6.0 upgraded to the Bulletproof Diesel oil and egr cooler. read more

NOT WHAT THEY USED TO BE !!!!! Their even BETTER !!! Hadn't I had been a previous customer in the past I would have never imagined a shop could be so welcoming and capable. Years ago Diesel Tech worked on my truck ( just recently got rid of it ) and their experience and 1st hand industry knowledge far exceeded my expectations. Upon purchasing my new truck, 2017 Ram 3500, I knew who to call for my intended aftermarket upgrades. After some good natured kidding about the Ram Loren sourced my items and set me up with an appointment. Upon arrival Mike met me in the office with a very welcoming "good morning how may I help you". Told him who I was and I had an appointment. Loren came right in and took possession of my truck and got it to his technician Jim for my install. Jim did a GREAT job taking care of my truck. Once finished Loren went over the truck with me to ensure I was happy. Diesel tech's work ethics, friendly staff with strong community ties ( easily proven with all the plaques and thank you on their walls ) is the reason I drive 175 miles round trip to have them work on my truck. As in the past and again yesterday Diesel Tech will continue to be my DIESEL TRUCK shop. Thanks again for everything. read more

just want to said thanks to all the tech's (((((especial thanks to loren)))))hope i got you name rigth,,,,, i send my f350 not running(hydrolock) and they took 2 days to get my truck ready,,,replace o rings on #2 injector,replace computer connectors,oil change with the rigth oil filter(motor craft),,,,thanks guys!!!! read more

The greatest Ford diesel repair place on the planet. Our company has a dozen ford diesels. We fix the simple stuff our self, but send all the harder stuff to Diesel Tech. They have always been honest, fast, and great. Once, we took a truck in an engine leak problem, and they diagnosed it. They told us what was wrong and what it would cost for them to fix it..... and then asked us why did we bring it to them; it was still under Ford extended diesel warranty! They could have had the repair, but sent us to Ford instead. Cant find that kind of honesty much anymore. They know their stuff, use only real ford parts, are a very busy shop with tons of return customers, and are wayyyy cheaper than Ford. No brainer. read more
