Colorado summers are beautiful. They're also hard on your engine.

High temperatures combined with elevation changes put extra strain on your cooling system. Low or degraded coolant means your engine runs hotter than it should, and that can lead to bigger problems down the road.

Our Pit Crew Certified technicians check coolant levels and condition as part of every visit. If a coolant fluid exchange is needed, we'll walk you through it before any work begins. No pressure, no surprises.

Noticed a spot or puddle under your car lately? It might be easy to brush off, but fluid leaks are your car's way of telling you something's wrong before it becomes a bigger problem.

Here's a quick color guide to help you identify what you're looking at:

🔴 Red or pink fluid: Usually transmission fluid. Left unchecked, it can lead to slipping gears, overheating, and costly transmission damage.
🟢 Green or orange fluid: Likely coolant. A leaking cooling system puts your engine at risk of overheating.
🟤 Dark brown or black fluid: Engine oil. Common but important to catch early.
🔵 Clear or light blue: Could be windshield washer fluid, but if it smells sweet, it may be coolant.

If you're not sure what you're looking at, our Pit Crew Certified technicians can inspect it, diagnose the source, and take care of the repair. No surprises, no pressure.

No appointment needed at any of our Denver metro, Colorado Springs, or Fort Collins locations.
