Basically, it’s a valve that regulates the engine’s temperature. It controls the flow of coolant – that’s the stuff that keeps your engine from overheating – to the radiator. It opens and closes depending on how hot the engine is. It doesn't make the engine cool, it just directs the coolant where it needs to go. Think of it like this, your engine generates a lot of heat when it’s running. The thermostat’s job is to make sure it stays at the right temperature. When the engine is cold, the thermostat stays closed, letting the engine warm up quickly. Once it reaches operating temperature, the thermostat opens, letting coolant flow to the radiator to be cooled down. It’s all about maintaining that sweet spot for efficiency and preventing damage. It’s part of the cooling system, naturally, working with the water pump, radiator, and hoses. If the thermostat fails, things can go wrong quickly. If it gets stuck closed, the engine will overheat – that can cause serious damage, like a blown head gasket or even a cracked engine. If it gets stuck open, the engine will run too cool, which can also cause problems. You’ll notice if it's failing – either your temperature gauge will be reading higher than normal, or the engine will take a really long time to warm up. It’s a relatively inexpensive part to replace, and doing it before it causes bigger problems is a smart move. You can find a good one at places like Fixparts Online, and honestly, replacing it proactively is much cheaper than dealing with an overheating engine.
