Why Is My Car Thermostat Important?

Your engine's cooling system includes a thermostat that controls the flow of coolant from your engine to your radiator. The thermostat is designed to open and close at specific temperatures to circulate coolant throughout the system and the radiator to regulate its temperature and prevent overheating. With time, your thermostat may become stuck, preventing it from opening or closing as it should. A thermostat that is stuck open can cause the engine to heat up slowly, or it may fail to reach operating temperature at all. This may affect your engine's performance, and can also keep your heater from working as intended. If the thermostat doesn't open or won't stay open, the coolant won't be able to move to the radiator and the engine will quickly overheat. This can cause damage to head gaskets and other internal engine parts, and could even cause your engine to seize, cylinder heads to warp, and more. If you've noticed your vehicle is overheating and suspect your thermostat has failed, consider replacing your thermostat with a new one from O'Reilly Auto Parts. We carry thermostats designed to open at the appropriate temperature for your vehicle, as well as radiators, hoses, and other cooling system repair parts for most vehicles to help you make a complete repair.
