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.

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.
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.
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.
509 Roadside saved my day. I locked my keys in my trunk and called insurance to have them help connect me with someone to get into my car. I was waiting for the maintenance truck to come, 2.5 hours after my call. 509 Roadside was just driving by and helped. Super nice guy!
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.
509 Roadside put in a left foot pedal, brand new brakes, and rotors and rear drums on my car. Also checked all fluids and cleaned engine bay. They were fast, friendly, and went way above and beyond for me. I would give these guys 20 stars if I could!
I am a hostler driver in our yard and anytime I need repairs, I call on 509 roadside, they haven't disappointed me at all. Very professional and courteous, I strongly recommend them.
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.
