Your thermostat helps regulate engine temperatures by allowing the coolant to circulate through the radiator once it opens. If it fails, this might mean it never closes, but worst case, it could mean your coolant doesn't get to the radiator. Stay ahead of cooling issues by replacing your thermostat regularly with an OEM thermostat or quality aftermarket thermostat from our selection.
