My AC quit working. I took my truck to 2 different mechanics before I was able to get it to the guys I trust, Dierks Diesel. The previous mechanics quoted full replacement. Dierks diagnosed the problem as a simple valve replacement and saved me over a thousand dollars. Now my AC works great. These guys know their stuff.

Great experience working with Dierks on a 90K service for my Yukon (Gas motor). I will be using them in the future when I have automotive needs.

Dierks Diesel never disappoints with their service. They found items that needed attention first time that the dealership should have. I will always use them for all my diesels!!! Staff has great communication and friendly. Highly recommended
