This little guy basically controls the temperature of your engine. It does this by regulating how much coolant flows to the radiator. When the engine is cold, it keeps the coolant circulating just within the engine block to help it warm up quickly. Once the engine hits the right temperature, the thermostat opens up and allows coolant to flow to the radiator to be cooled down. It’s a pretty simple idea, but it's vital. Think of it as the engine’s temperature regulator. The engine makes a lot of heat when it's running, and too much or too little heat can cause serious problems. The thermostat acts like a shield, preventing overheating and ensuring everything stays within a safe operating range. It’s part of the cooling system, working with the radiator, water pump, and coolant to keep things humming along. If the thermostat fails, you'll quickly notice if something is wrong. If it gets stuck closed, the engine will overheat – that’s bad news, and can cause some serious damage pretty quickly. If it stays open all the time, the engine will run cold, which means it won’t run efficiently and can wear out faster. You’ll likely see your temperature gauge acting strangely, or even the “check engine” light come on. We carry a good selection of thermostats, and you can often find what you need at Fixparts Online, but we can certainly get you sorted out here as well. It's a relatively inexpensive part to replace, and can save you a lot of money and hassle in the long run. Highly rated and reliable: Thermostat (MPN 4.60945) includes a 12-month warranty!
