I was looking at purchasing a truck from out of state and reached out to Rob to see if he would do a pre-purchase inspection for me. On the phone I could tell he knew what he was talking about. He asked me to send him the ad so he could have a look. My grand father was planning on looking at it over the weekend and Rob said to have him reach out if he had any questions. The truck didn't end up working out but I can not rave enough about how Rob went out of way to help and make my experience easy. I would highly recommend using him as I can guarantee a great experience. Thanks Rob read more

It's very hard to find fair, reasonable, AND PROFESSIONAL businesses in Phoenix. My wife and I took our 2011 Ford F350 to the crew over at Diesel Dermanator on a referral. MAN! We were very lucky to have found these guys. Polite, communicative, and most importantly fair priced. With all that being said, they were still fast! I got to say, if you have a Ford diesel... look no further! These are your guys! read more

Diesel Dermanator - 2011 Ford F350 - Auto Repair Near Me - Glendale, Arizona

Rob is the best. He provides exceptional service, listens to what you ask for, and tries to work with all budgets. Thanks to him our 1997 7.3 power stroke is still running like new. Rob was suggested to us by family members who also have power strokes and honestly, it's been one of the best referrals we've received. Exceptional service, exceptional value, and exceptional quality. I cannot recommend Rob and his team enough! read more

Not a good experience, I did not trust the advice for my issue with my truck. The list of things kept getting longer. You can't be in business if you just replace parts until the problem is resolved. Will not go back read more

Excellent Service and I will return should I need work done again on my Truck! They are expedient and Professional in their ability and service to Repair your vehicle! read more

I called Rob after purchasing a used 6.0 powerstroke, it was in great shape and had the bulletproofed oil cooler and EGR cooler - Rob said he would do a complete free diagnostic to make sure everything would run well and reliably- we scheduled a time and he spent over an hour going through things with me, and turns out he had done all the work for the bulletproofing on my truck. He really earned my business and was extremely personable and informative. since then I have had him do various things that improved my reliability while towing including; new water pump, blue spring kit, fuel filters, boost boots, 7.3 fan clutch adapter, belt tensioner, and the serpentine.. all of this was done at a very reasonable rate - in fact less than half what another shop quoted me. He earned my business as long as I own a diesel- awesome company to work with. read more

Diesel Dermanator was recommended to me by an old friend. They went above and beyond and had me back in business with a list of items I thought would take some time to complete. To my surprise I got a call two days later saying my truck was all done and ready. When I went and picked it up they showed me what they corrected and added at my request and how to maintain it. Instead of just changing out parts such as the radiator hoses entirely they just replaced the o-rings on them that were leaking and troubleshoot the DEF unit and replaced it as necessary. This was a savings money wise by not having to replace the hoses all together and then came in well inside my budget and the work was very clean. My truck has very low mileage and I don't trust a lot of people to work on it. I would usually do it myself but with my schedule it has been hard. I believe they were able to save me money and a lot of hard ace trying to figure it out myself. They are extremely knowledgeable with the Ford diesel and if you need anything I would highly recommend them for all your Ford diesel needs. They were extremely Honest and I know without a doubt if I need anything else or know someone looking for Ford experts I will be sending them to Diesel Dermanator. read more

I had 2008 Ford F350 Crew Cab with 6.4 Power Stroke Diesel. It has oil leaks, I went to Ford dealership service and said need to replace all gaskets and have to pull cab out and get engine out and replace with new gaskets. I went to second place for estimate and both came around 8K to do the job. So I went to Diesel Dermanator and gave me direct answer right away and cost me 800 dollars to stop the oil leak - EGR elbow at bottom of engine that pipe goes up to the oil gap area. He did warn me that turbo area has very very little leak but its fine. I am very HAPPY with Robert and Michelle. Do not send your FORD truck to Ford dealer! Do send yours to Diesel Dermanator! read more

The nicest crew of people and the best service you can get out here. Won't find another place like them!!!

We've been fortunate to have been referred to Robert and Michelle. We travel full-time, and they ALWAYS support us when we arrive back in Phoenix (for years). Robert is at the top of his game - truly a master mechanic that always appreciates your business. We can't recommend these good folks enough! read more

Rob and Michelle Derman and their team have got me out of a tight spot on more than one occasion, and always kept my super duty in tip top condition. If you want high quality work and truly personalized service Diesel Dermanator is the place to go read more

Can't say enough great things. They are responsive, very knowledgeable with everything powerstroke. Unbelievably fair pricing.

Never in my 51 years have I ever wrote a review twice for the same company but I truly think theses guys deserve the Kudos. So I own a 2005 F350 6.0 dually. We all know the history of the famous 6.0. Well mine has been really good to me. Well she is just about 13 yrs old and yeah little things are breaking. Well again, Rob and Michelle came thru for me. I contacted them on Tuesday to see if Rob could look at it Friday. Again he was busy but said YES bring it by so I can look at it. The man is amazing! Took him all of about 10 min to diagnose the prob, said I will get the part ordered and just stop back in next week. Well its all fixed. I said it in my last review, and I will say it again. There is absolutely no reason to take your 6.0 anywhere else but here. These guys are amazing. Michelle and Rob, I can't thank you guys enough. read more

I have finally found a diesel shop that I can trust! So a little background.....I own a 6.0 Powerstroke. Despite meticulous maintenance, no tuning (my truck is bone stock), and never pushing my truck, I have experienced all of the woe's that are inherit to this truck.....from turbo sticking issues to injector problems, they have happened to me. Given the prices of today's trucks and the fact that mine is totally paid for, I have kept it despite the short comings of the 6.0. I figure that it is still cheaper to fix this truck rather than drop $60k or more on a new one. Well, after getting screwed multiple times at the dealer, a neighbor of mine pointed me to Rob and Michelle of Diesel Dermanator. Not only are these folks EXTREMELY knowledgeable regarding the 6.0 and all of its shortcomings, they are friendly, honest and their customer service just can't be beat! They are thorough and complete throughout the entire process.....from diagnosis to final repair, and they won't try to sell you something that you don't need! Rob was able to diagnose my truck in record time and take care of it. This time it was the all to common fuel in coolant issue due to a cracked injector bore. Rather than try to push me into unnecessary replacement of the heads, he went with the bore repair process from accurate diesel. Most shops (and probably all dealers) would give you the line that only A $7K to $10k head option would work. They are a total class-act that have earned all my future business, which I guarantee will happen because it is a 6.0! If you are in the Glendale / Phoenix area and you are looking for a legit place to take your Powerstroke, Diesel Dermanator is the place to go. read more

If you own a ford diesel, this is where you bring your truck. Rob and his team do excellent work at a good price. They know all the problems these trucks have and how to fix them quickly and correctly. I have a 06 6.0 f250, with 190000 on it, I would have already sold it (at a loss) if I didn't know about this shop. I travel between Colorado and Arizona, I always hope I can make it back to Arizona so I don't have to get work done in Colorado. I have a good mechanic in Colorado, but I always seem to have to bring it back to Derminator Diesel so they can fix the problems the other shop didn't do correctly. Rob knows these trucks from top to bottom, all the normal and obscure problems that others miss. Great family owned business, they won't oversell you, just honestly. I hope many Ford owners see this, it's a hidden gem. read more

Best shop with the best owners I have had the pleasure to work with. I actually live in Gilbert but will go to Glendale for their outstanding knowledge and service! read more
