FAQs
How Can I Get Coolant System Repair?
Call 509-855-4932 now to book a service appointment. Whether it’s a leaking radiator or a bad thermostat, we’ll get your cooling system working reliably again.
Can I Still Drive With a Coolant Problem?
Driving with a coolant leak or failing component is risky. Without proper cooling, engine temperatures can spike quickly, leading to major damage. It's best to stop and have the system inspected as soon as possible.
What Are the Common Signs of a Malfunctioning Cooling System?
Look out for overheating, coolant leaks, steam from the hood, or fluctuating temperature readings. You might also notice a drop in heater performance or a sweet smell under the hood—both signs of trouble.

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.
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.
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!
These guys got me in to their shop on short notice and found my electrical problem quickly. Can’t thank them enough! I will call them again if I need help in the area!!
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!
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!
I can’t speak highly enough of the service I received from 509 Roadside. My F150 was throwing multiple error codes and knocking, and eventually stranded me off I90 on a Sunday afternoon. Joseph with 509 was extremely patient and attentive, and helped walk me through problem solving over the phone, and I was able to get back on the road. (For a bit, but that’s the truck’s fault and not theirs!) Five stars, and I’d give more if I could.
