Subaru Thermostats

What does the factory thermostat in a Subaru do? More importantly, how does it work? The short answer is that it helps keep your engine from overheating. However, it's less obvious how a cooling system valve can achieve this. Yes, how your original Subaru thermostat works is simple: it opens and closes, often thanks to a spring or piston, and this keeps coolant circulating through your engine and radiator the way it's supposed to. However, it's precise timing that's key. After all, coolant must stay at the right temperature, whether it's warm or cold out. It all comes together, thanks to many auto parts working in sync. Is your temperature gauge giving constant readings, centered or just slightly cold? Then it's working normally. Thankfully, thermostats don't usually go bad with age either, so when to replace a car thermostat isn't usually something you have to worry about. However, that doesn't mean a thermostat can't fail. There are signs your thermostat isn't working right. They include a Check Engine light, improper valve opening and closure, and a stuck valve. These issues usually appear as engine and AC and heating problems. A malfunctioning valve can't move coolant correctly, and this can either cause an overheat or keep coolant from reaching the correct temperature. Engine efficiency can tank, and your HVAC system can stop heating right. Nearby auto parts, like the surrounding hoses and gaskets, can even warp, if they don't immediately malfunction, too. In any of these cases, do an inspection. If you need to replace your car thermostat, do it with a genuine Subaru thermostat. You can order one online at low cost from our auto parts counter.
