In years past, the diesel market was heavily involved Welcome to Left Coast Diesel, your northern California Leader in diesel services, repairs and maintenance. Over the last 13 years of quality work our vision and what we are here to achieve for our customers has always been to help keep and make their rig dependable and on the road. In years past, the diesel market was heavily involved in aftermarket accessories that were build around fuel mileage and more horsepower. While these products offered much immediate gratification on older vehicles, we have seen over time that maxing out many of the factory components(I.E. Turbo and injectors) the truck starts to see repairs sooner than vehicles that have remained stock throughout their lives. ...more

Excellent quick and professions job
Been taking my truck here for 11 years. Always professional and do the necessary work, while advising on things to keep an eye on. This visit was just an oil change, but they did it while I waited which was a huge help for me.

Good Careful Mechanics
I’ve known Ross and his team for a few years now and he treats my truck like his own and treats me like a client. Good communication, knowledgeable service and fair prices. Not sure what else anyone would expect. I am thankful for his work on my 2001 F250 7.3 Powerstroke.

Excellent customer service!
Left Coast has been servicing my Dodge for the last 3+ years. They have always gone the extra mile. My last repair was a transfer case replacement. It took longer than expected to get the part from the east coast, but they came in on Saturday to get my truck back to me before the holidays. Thanks Ross and the rest of the team. Much appreciated.

Dishonest and Deceptive-Stay Away!
This mechanic shop outright lied about their quote. They gave me one price at the beginning, and by the time the work was done, it was way higher. They didn’t bother to explain or get my approval before inflating the cost.

This kind of shady business practice is unacceptable. If you value honesty and transparency, take your car somewhere else. They clearly can’t be trusted.

Oil leak
I brought my 18 Ram 2500 Diesel in for a front end oil leak. The guys were knowledgeable and friendly. They communicated with me the whole time they had my truck. I felt they were very thorough and trustworthy.
