OEM Honda Thermostats

Refine Results
What does the thermostat that comes factory-installed in your Honda do, and how does it work? In all cars, trucks, and SUVs, thermostats help prevent engine overheats. But how does a simple valve located in your vehicle's cooling system achieve this? It opens and closes using a spring, piston, or something else thermally controlled. This simplifies regulating coolant recirculation in both the engine and your radiator. That means the coolant stays within an acceptable temperature range regardless of how warm or cold it is outside. Your next question is probably "how do I know when to replace a car thermostat?" The good news is that thermostats generally don't go bad with age. If your vehicle temperature gauge keeps giving constant readings and needle or bar graph remains centered or just on the cold side, everything's working normally. However, if you're doing cooling system maintenance on an older Honda, like flushing coolant or changing a radiator or radiator hose, it might be good to replace the thermostat on principle. Besides a Check Engine light, though, there are signs nevertheless that a thermostat isn't working. Your valve may stop opening and closing normally or get stuck closed, trapping coolant in the engine and causing an overheat. The valve could also get stuck open, causing coolant to circulate too much through your engine and radiator. This keeps an engine from reaching the right temperature, reducing efficiency and causing your HVAC system to stop heating correctly. Overheating can damage the valve, its housing, and your cooling system's hoses and gaskets alike, too. That's not to mention that too much heat can warp nearby auto parts and cause malfunctions. If you need to change your car thermostat, the best choice for the job is a genuine Honda thermostat. Order now from our online auto parts counter and finish your project in no time!
