    The thermostat is a physical valve that controls engine temperature. It blocks coolant flow to the radiator until the engine reaches a predetermined temperature. This allows the engine to warm up quickly and efficiently. The thermostat is controlled either mechanically or electronically. During engine warm up, it remains closed to allow the coolant in the engine to warm up.

    At a specific temperature the thermostat opens, allowing coolant to circulate through the entire cooling system. From there the radiator and radiator fan to take over temperature regulation. A thermostat that is stuck open can cause the engine to run colder than normal and set the Check Engine Light.

    It may also cause poor fuel mileage and the heater to blow cool air. A thermostat that is stuck closed will cause the vehicle to overheat. If the new thermostat does not immediately resolve engine temperature problems, the cooling system needs to be checked for other issues.

    Signs of a bad thermostat, and how to fix it. A thermostat that is stuck closed can cause the engine to overheat. An overheating engine should be shut off, and the vehicle towed.

    Overheating can cause coolant leaks , steam for the engine, a blown head gasket, and ultimately a failed engine if driven for too long. If the thermostat is stuck open it may not cause engine failure, but poor running, an ineffective heater, and increased fuel consumption may result.

    Replacement intervals vary greatly by vehicle and driving conditions. The thermostat does not wear like a tire or a ball joint, but will eventually fail and require replacement. Often times the replacement of the thermostat is recommended as preventative maintenance any time the cooling system is being serviced, such as during radiator hose replacement or a timing belt service.

    A comprehensive inspection of the entire cooling system will be performed, including the water pump, heater hoses, cooling fans, and thermostat. With the engine off, the technician may perform a pressure test to ensure the cooling system is sealed. Radiator hoses will be inspected and should be replaced if old or leaking. Brittle or oil soaked hoses could fail soon after replacement, necessitating additional repairs. Where applicable, any trouble codes stored in the engine's computer will be pulled and the relevant diagnostic procedures will be followed.

    The engine temperature sensor may be tested, and the thermostat opening temperature checked. If the engine has overheated the shop will inspect for signs of engine damage. Modern engines commonly have composite plastic parts such as intake manifolds and thermostat housings that can warp from engine overheating.

    These parts, along with the head gasket, should be checked for leakage. To replace the thermostat, the technician will drain the coolant from the system and remove the thermostat housing and thermostat from the engine. Many modern engines have thermostats that are integral to the thermostat housing and require complete replacement.
