Best place in town for diesel performance and repair
My Duramax was acting up about restricted fuel coming back from a long trip pulling a toy hauler. Took it here for diagnostics, Mike asked to look at first and recommended replacing the fuel filter with a better brand. That seemed to have worked. They didn't try to charge me a dime! I appreciate the honesty!
Gave us a quick price on service.
Mike and Mark at 23 Diesel were some of the most acceptional mechanics I’ve worked with. I brought in my Mercedes Sprinter Van and had them do some work to it. They were extremely knowledgeable and very patient. It takes a specialized mechanic to work on this rig and I wish I had found these guys sooner. There experience with diesel engines is unmatched in the grand valley. I would highly recommend these guys to anyone! They were also super honest about their work which is hard to find when it comes to a mechanic.
Mark and Mike are awesome guys. I went to the shop after looking for someone i could trust with my modified diesel truck. I believed i was having issues with my injectors. With that being a very spendy repair bill i was looking for someone who would give an honest answer and not just look at me as a dollar sign. These guys got my truck in and used the proper diagnosis tool to give me the news I was looking for. No injector issues!!!! Lets just say these guys have earned my business and will recommend them to anyone who has a diesel vehicle. Thanks again Mark and Mike.
These guys hooked me up. Mark knew instantly what my problem was after 30 seconds on the phone. Cool, friendly, and helpful, these guys are sincere in helping me keep my diesel maintained for a long life. Thanks dudes!
Our truck broke down while traveling through town on vacation. These guys went above and beyond to get the truck running again. If I lived closer I would use them for all my truck needs!
You need your truck or SUV running better? This your place! From oil changes to full on builds we have you covered!
Mark and crew are very helpful. Having issues from another shop and are willing to take the time to offer solutions
Amazing people amazing service
My Girlfriends Van broke down in the middle of nowhere. These guys really took care of her and I am very thankful.
Mike did a fantastic job with my superduty. First class service all the way. Highly recommend 23 diesel!
Found the last place I will ever need to go for my diesel needs. Mark & Mike are both knowledgeable and happy to answer questions. Great prices as well!. I really can't say enough about this place. If your going elsewhere your paying more and not getting it done right.
Very knowledgeable staff. Good prices and correct diagnosis of my problem. Got me fixed up in a timely and affordable matter.
