FAQs
How Do I Know If My Diesel Engine Needs an Overhaul?
If you’re experiencing excessive oil consumption, loss of power, hard starts, or blue smoke from the exhaust, it may be time for an engine overhaul. Proper diagnostics can confirm the condition.

Saying About Us
See why our customers consider 509 Roadside their go-to repair shop in Moses Lake, WA and the surrounding areas!
Joseph helped me out when my car couldn’t shift gears coming from Spokane, going back to Western WA. It was 99 degrees out and he came from his house to help me. He was calm, knowledgeable, communicated well, and honest. He even called me when I got back home to make sure I made it and gave me some car tips. There aren’t too many people out there like him. I believe in karma, and Joseph deserves all the best karma his way.
These guys came out and did a roadside repair on my trailer and got me patched up in no time, their mechanic even followed me to my destination to make sure everything went smoothly. They went above and beyond, excellent and professional service. Thanks guys!
Joseph did a great job replacing a small engine for us. He searched, bought and replaced it for us while keeping us informed every step of the way. With great pricing and service, we will continue to utilize him in the future for our needs.
Our resident transport bus broke down on the way back from Wenatchee. 509 Roadside made arrangements to get the vehicle towed to the shop and had it fixed the very next day. Great service!
Had issue with semi shutting down due to coolant level issue, contacted 509 to assist and they were earlier then expected, very friendly and got me back on the road quickly and went beyond duty and even checked other things to prevent any other issues. Would call them first if I ever have a problem down road.
509 Roadside is amazing. I was driving my truck and was in the area with an airbag broken on my trailer. I called 7 different shops within 100 miles of Moses lake around 1pm on a Thursday 3/13/25 and 509 was the only one to answer. Not only did they answer but they took the time to find the correct airbag and get me safely back on the road at a very reasonable price! It was a great experience and I will definitely be using their services again if I’m ever in need.
Joseph and the 509 Roadside crew have been an invaluable part of keeping our fleet of delivery trucks running reliably here at Culligan, and it has been great having such a fantastic, local mechanic. He is consistent, thorough and always goes the extra mile to ensure our vehicles are in excellent condition. His attention to detail and commitment to quality work are evident in every job he takes on. Knowing we can count on him for fast, dependable service makes all the difference in keeping our operations on schedule. Very highly recommended for all your fleet needs!
Totally helped me out of a jam. Last Wednesday 2/26/25 late in the day, my 2011 Isuzu Blue Bumper Box truck had a red check engine light go off. You guys were my angels. Thanks so much for clearing the code and getting my truck back on the road. It made it all the way to Spokane and back to Seattle.
