My truck caught on fire. I was 2+ hours away from home, my 5th gen Cummins was parked in front of my friend's house when smoke started pouring out of the hood. The known problem of the air exchange/heater relay problem with these engines had come to life, the known bolt that falls apart and blows your engine up didn't happen but it had come loose and arced enough to catch surrounding wires and foam insulation on fire. My first mistake was taking it to the local dealership where they quoted me a large amount of money and didn't not want to categorize it under warranty. Loomis Diesel was suggested by a friend, I had the truck towed there. While I was 2+ hrs away, they kept me in the loop about every step they were taking to repair my truck and work with my auto insurance. I honestly didn't have to do much but make a couple command decisions along the way. A month later my truck was repaired and improved, covered by insurance, and ready to come home. The communication with Loomis Diesel was perfection, the descriptive details of the project were simple enough for me to understand, the confidence that I had in Loomis Diesel was at 100% because of their communication and honesty. Although I am a good drive away from them, I will surely take my truck with any big problems/projects to Loomis Diesel. It's like finding a good barber, you"ll never change. read more

My wife put 87 gas in my diesel truck and drove it for 6 miles. Jacob and his guys did a great job getting me back on the road. Highly recommended for their communication and quality of the repairs. read more

I bought a 1994 7.3 idi that was a basket case of issues. Blake helped me trouble shoot some of my issues over the phone. When I had an oil cooler go bad on it. Blake helped me out with getting the work done in a reasonable time frame. He did rebuild the oil cooler but noted that the oil cooler housing was looking like it was starting to flake apart (no new replacement parts available). Fast forward about a year and the oil cooler went out again. I called Blake asking him what I should do (I moved out of state). He reminded me that his work has a 2 year-24,000 mile warranty. He said I could take it to any participating Napa Service Centers and get the work done free of charge. Found a new shop that will do the work under warranty. Thank you Loomis Diesel for helping me solve a difficult problem and all of the other problems this truck has given me. Housing is getting replaced second time around. read more

They have worked on my 99. They even worked on my 08 which is a gas truck. Diagnosed a problem on my 20 over the phone. Letting me know the problem so I could fix it myself as it was not safe to drive. They are friendly, helpful, quick and reasonably priced. Wayne from Rocklin Foriegn car recommend them for my diesels. I now trust no one else with my fleet trucks. read more

Loomis diesel treated me very well! They were the only shop in a 50 mile radius that would even agree to work on my 09 6.4 powerstroke. The issue ended up being less intense than we anticipated and they were excellent communicating through that. The truck went on a 7 hour trip the day I got it back and did great. I'm sure I'll be back, but I'm glad to know I have somewhere reliable to work on my truck now. read more

GREAT SERVICE , fair pricing. This shop goes above and beyond! Can make reservations and wait for service. Eliminates need for a ride

I have a 21 f 250 6.7. Love this truck. But unfortunately it broke down. Don't hate. Anyways the CP4 pump went out. I called Blake to see what his opinion was and he went above and beyond. We actually live a couple blocks away and I was unable to drive my truck so he made personal time and came to me. Not only did he diagnose it within 5 min he also got me in his shop the next day! Ordered all the parts and got it done very fast! First test was hauling my camper 6 hours round trip up steep inclines and the truck ran perfect! All in all these guys rock! Hopefully I won't need them anymore but if I do I'm going right back to Blake! Thanks guys! read more

I have a 2007 Silverado Classic Duramaxx Diesel and have been hunting for a good trustworthy shop to do any repairs that come up and luckily, I was recommended to Loomis Diesel by a former employee of Blakes. I called and made an appointment, as I had numerous issues and the day that I was going to drive it in, I started it and it instantly died and I had to have it towed down to Loomis Diesel.The next day Blake got it started and went through what should be done to it and what it would cost to get repaired. I agreed to the estimate and Blake took care of it immeadiately. He drove it for 22 miles to put it through some good tests and was very thorough with the repairs. What I especially like about Blake and his wife Ashley is that they explain exactly what your options are and let You choose which way to go. They keep a clean shop and have a nioce corporate yard that locks up and is secure. Loomis Diesel is the place to go for any Diesel Service and I live in Antelope and it's definately worth the drive to Loomis Diesel for any diesel issues. read more

What a great diesel shop! My only complaint is I wish I'd found them sooner. I wasted A LOT of money and 10 days in the shop at a diesel place in Rocklin off 65 trying to get a diagnosis to an idle problem. Blake dialed it in in no time and my LMM Duramax is back on the road. Efficient diagnostics. No upselling me parts that I don't need. Quick turnaround. This is the most trustworthy diesel shop I've ever been to. Thank you to Blake and the crew for the quick honest repair. read more

Loomis Diesel is my go-to for all my maintenance/ repair needs. I trust Blake and his team to guide me through options and provide excellence and value. I have had my truck (GMC 2500) fixed/serviced 5-6 times and have never been disappointed. He is in the process of expanding. Give Loomis Diesel a try! read more

After having a poor experience with an OEM dealership I found Blake and his team at Loomis Diesel for an injector replacement on my 2015 DuraMax. Blake's extensive repair knowledge with his excellent mechanic's completed the repair in a third of the time others had suggested. The truck runs beautiful and is ready for our summer vacation. I would highly recommend Loomis Diesel for any of your makes of Diesel Trucks. Thanks again Blake to you and your team. 5 stars is enough as far as I'm concerned. Preston Smith read more

Let me start by saying I haven't had any work done to my diesel truck at Loomis Diesel. But I called Blake (owner) and spoke with him over the phone about work I've had done to my truck and an issue I continue to have. He took the time to listen and hear me explain what's going on, and gave some advise on what could be the issue I'm having. His advise was in line with another diesel mechanic and has given me a direction to go to try and resolve the problem. I really appreciate the time he spend on the phone with me and if I don't do the work myself, I will be calling Blake to schedule an appointment to bring my truck into him. Thanks Blake for all the advice and being straightforward about what you do and charge. read more

Blake was incredibly knowledgeable and extremely flexible with seeing my truck. He was able to diagnose the issue and advise the work needed all free of charge. Other shops required a fee before diagnosing the issue. Will definitely be back for any future work. read more
