Downtown Cleveland fluid services
Your car runs on more than just oil. Coolant, transmission fluid, brake fluid, power steering fluid and differential fluid all break down over time, and dirty or low fluid is a leading cause of expensive breakdowns and overheating. Staying on top of fluid services is one of the cheapest ways to protect your engine and drivetrain. Our shop in the bottom of the Hamilton Garage at Hamilton and East 12th makes it easy to keep up while you work downtown.
Our ASE-certified team checks the condition of every fluid, tops off what is low, and recommends a flush only when it is actually due, not on every visit. We follow the factory schedule and back qualifying new parts with our Fixed for Life warranty. Many customers pair a fluid service with an oil change to save a trip. Honest advice, fair pricing and no upsell.

Reliable, great customer service. I went in for a wheel alignment and they did a complete inspection and topped off my fluids. Highly recommended!
Had a wonderful experience at Rad Air today. Paul assisted me when my car said I had low tire pressure. They checked the tires and found all of them to be low, so they filled them and topped off all my fluid levels for free. I am so pleased and grateful. Thank you Paul, you made my day.
Rad Air changed the water pump and thermostat on my Dodge Durango and did an impeccable job! These guys are my go-to for clean, professional work!
Paul is absolutely amazing. Very responsive to any concerns and great about setting timely appointments. He explains repairs clearly, especially for someone like me who doesn't know a lot about cars, and he is honest about critical repair needs versus repairs that can wait.
Paul really prioritizes getting you back on the road safely. No fluff. If it needs to be done he'll tell you.
Fast service and transparent pricing. Definitely going to be heading back there next time my car needs work!
Paul and team were amazing! Excellent customer service and professional work. I highly recommend them!
Reliable, friendly and honest! I tried other shops in the area before coming to Rad Air and I wish I had just started here first. I will keep coming back!
Paul and his team are excellent to work with. They were clear with what they found, providing an estimate and completing the work quickly. Great job!
They always get work done in a timely manner. Prices are reasonable as well. The manager is very helpful and makes the entire process very easy. Highly recommend coming here!
From the time I dropped my car off I felt I was in good hands. When it was explained what was needed and why, I was confident in what I was told. I have no complaints and will return if another concern arises.
Paul and his team have always been professional, prompt and transparent. The location and convenience cannot be beat, and they have always treated me right, never pushing for unnecessary add-ons or repairs like some shops do.
