Grain Valley Auto Repair

This shop is amazing, honest hard working and knowledgeable. My number 1 pick for diesel repairs!

Absolutely the best diesel mechanic I know!

Always A+ service .. in an out in a day ..= excellent

I took my 1999 7.3 Ford Powerstroke to Drews because it was running really poorly. He diagnosed the problem quickly and kept in constant contact with me about the progress. He did a great job and the truck us running perfect. It was money well spent. I will be using him in the future for sure.

Excellent work and reasonable shop rate. I was. Referred to this shop and happy to say i am satisfied with the work i had done

While travelling back to Denver I had a breakdown and was referred to Drews. Andy and his staff had me back on the road within 30 minutes. I could not have been more impressed with the service and kindness I was shown. I would highly recommend this shop to everyone.

Andy and I worked together years ago when he was still a young pup lol, was told about Drew's Diesel through a friend that turned out to be a mutual friend, when I found out who the owner was I didn't hesitate to have him diagnose the problem, my 6.0 I thought had a failed injector, turns out I had a cylinder that failed, he saved me a ton of time diagnosing and troubleshooting, definitely check this gentleman out if your having issues!

Awesome service and the knowledge to fix problems....

Bought this 2006 dodge 2500 5.9 Cummins a few days ago and took it to Andy too look over the whole truck and fix a fan clutch and bearing and a few other things. He did great work and fixed it in a day! I will definitely be back for sure!
