Coolant leaks can be a pain - they’re elusive and have a lot of damage potential. Fortunately, at Harold's Used Auto Parts Inc in Philadelphia, PA, our technicians know exactly how to diagnose and repair a coolant leak, no matter where it is. Knowing more about where these coolant leaks appear and why they're a problem will help you to recognize a problem and get it repaired before it does further damage.

Where do coolant leaks appear? A coolant leak can appear anywhere coolant is present, essentially. More than likely, leaks will spring up as a result of damaged or degraded rubber hoses. These hoses are subjected to a lot of heat, time, and wear, and eventually, it takes its toll. Particularly around hose clamps and in bends, leaks will arise.

Why are they a problem? Coolant leaks are a big deal. Coolant is under pressure, so once it begins leaking, it can leak out fast - in a matter of minutes, your vehicle will begin to overheat. Best case scenario, you’ll find yourself stranded, and worst case it’ll cost you an engine.

What makes it difficult to diagnose? Sometimes leaks are obvious, sometimes it takes a trained professional to locate and repair one. Often, there are small hoses routed underneath major engine components that are impossible to see when they fail. It just takes a pinhole to become a major leak when the system heats up and becomes pressurized, meaning it won’t leak cold making it even harder to find. A technician with the right tools and knowledge will sometimes even use UV dye or other methods to track down a leak. If you’re leaking coolant, keep a very close eye on your fluid level and engine temperature, and have it fixed immediately.
