As a Ram truck owner with Cummins power with Aisin tranny I have to be perfectly honest. Having tried to find service in San Jose area to no avail. Dealer and independent combined, I am a 1000% committed Loomis Diesel “groupie”. The customer service, knowledge, cost and professional demeanor are truly what a business strives for. From my, perspective, Jacob and his his team have accomplished this in A++ fashion. I will continue to commute in order to realize this service. Thank you for the opportunity to express my opinion.

I highly recommend Loomis Diesel for all your diesel and truck repair needs! Jacob is incredibly honest, professional, and extremely knowledgeable. He takes the time to explain everything clearly, and ensure the job is done right the first time. Whether it’s routine maintenance or a major repair, Loomis Diesel is the place to go!!

Big thumbs up for Loomis Diesel. They replaced my Turbo and a few other items on my 2007 Chevy LBZ Duramax. The job was done on time, at a reasonable price and the work was excellent.. The staff was friendly and great communication, kept me informed on the progress every step of the way. I'm a retired mechanic and I was impressed how organized and clean the shop was kept. This was the first time here, I'll definitely will be a repeat customer.
