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.

My window wasn’t working for the past 2 years and I was looking for a good mechanic for a while but they were too pricey. But 509 roadside did not disappoint! They were able to fix my window at a great price! Definitely recommend!! I can finally go through the drive through!
Had my starter go out they had a new on hand and I was back on the road right at 2 hours, great job 509.
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!
I started using 509 Roadside in 2023 and I can’t say enough good things about Joe and his team. They provide prompt and professional repair services for my equipment at very reasonable rates. Since my office is based outside of the region where 509 Roadside is located, they are a strategic resource for my equipment service needs.
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.
My car broke down and Joe found me stranded. He called a tow truck immediately and waited with me, I told him I thought my alternator burned out and he confirmed that was the case as soon as he walked up. He had the car fixed first thing in the morning and his rate was very reasonable. Joseph is a great person and an amazing mechanic. I highly recommend his services.
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.
