Exceptional Diesel Truck Mechanics

Honest, reliable, and efficient service for your light-duty diesel truck.

Minimize downtime by entrusting your diesel repairs to expert diesel mechanics

Diesel vehicles require specialized mechanics. Most regular mechanics don’t understand the complexities of diesel trucks which can lead to more time in the shop. Even worse, it could lead to bigger problems down the road if issues aren’t addressed properly.

About Us

Expert care for diesel
engines shouldn’t be
hard to find.

In 2019 we noticed a lack of shops in Spokane Valley that could service diesel pickups, so we founded Northwest Dieselworks.

Now, with 35 years of combined expertise and a passion for diesel engines, we’re committed to providing every diesel truck with the personalized care it deserves.

Jake and the staff are AWESOME!!! If you want your rig fixed RIGHT the first time, make your appointment NOW! Josh is detail-oriented and isn’t satisfied unless the job is done right.

My wife’s 2003 Ford Excursion, with 6.0L diesel, has more power and has never run better. My AM General Hummer is scheduled next, and I haven’t been more comfortable to entrust a shop to work on her.
Thank you for a job well done!

Jake and his staff have been the best to work with on my diesel truck for maintenance. I have been to several different garages but nobody compares to their customer service. They have went out of their way several times to get my truck back on the road when their schedule didn’t allow. Top notch and I would highly recommend getting any major or minor maintenance done from these guys.
