Basically, the thermostat controls the flow of coolant through your engine. Coolant, as you probably know, keeps the engine from overheating, but the engine also needs to warm up to run efficiently. The thermostat is the gatekeeper; it decides when to let coolant circulate through the radiator to cool things down, and when to restrict flow to let the engine get up to temperature quickly. It’s a pretty simple device, but it’s got a big job. Think of it as the engine’s temperature regulator. When the engine is cold, the thermostat stays closed, allowing the engine to heat up faster. As the engine warms, the thermostat gradually opens, letting coolant flow to the radiator where the heat is dissipated. It continually adjusts to maintain a consistent operating temperature. It works with the radiator, water pump, and cooling fan to keep everything balanced. A failing thermostat can cause a lot of problems. If it gets stuck closed, your engine will overheat very quickly, which can lead to serious damage, like a blown head gasket. You’ll notice if that happens – steam coming from under the hood is a pretty good sign. If it gets stuck open, the engine will run too cool, which can reduce fuel efficiency, increase wear and tear, and also impact performance. It’s one of those parts that, when it’s working right, you don't even think about it. But when it fails, it can cause a lot of headaches. We carry a good selection of thermostats, and you can also find them online at Fixparts Online if you prefer to shop that way.
