About NW Diesel Service

NW Diesel Service started as a one-bay, one-man division of NW Fuel Injection in the late 1990’s.  At that time, the only time we saw a pickup truck was to remove and replace the pump or injectors.  How the times have changed! We are no longer just a diesel truck repair shop.

We have grown to a 5 man 4000 sq ft full-service shop, fully equipped with the latest OEM and aftermarket diagnostic tools, factory and aftermarket training, experienced red seal certified technicians, and today we are leaders in our field.  Our technicians are continuously updating their skills and knowledge as vehicles increase in complexity.

We specialize in Powerstroke, Cummins, and Duramax, and can assist with everything from a basic diagnostic to full service and repair.  We’re not limited to under the hood – we also do transmissions, brakes, suspension, performance, and exhaust after treatment systems.

Effective December 2017, NW Diesel Service was sold to longtime manager Landis Schray and is now operating as Diamond Diesel.  Same great people, same great service!
