Dayco 87C Thermostat Housing DT251D

Dayco 87C Thermostat Housing Fits Volkswagen Jetta, Passat, Golf, Audi A3, Skoda Octavia

The thermostat's role in engine management is vital. A thermostat that has failed in the open position will make your heater appear not to work for an extended period during winter. If it fails in the closed position, it can cause your car's engine to overheat, leading to costly repairs or complete engine failure. Dayco thermostats are designed to OEM specifications and feature a heat sensing wax-filled copper power pill that detects the coolant temperature in the engine. This innovative design controls coolant flow from the radiator when the engine is cold, allowing it to reach optimum operating temperature quickly. Once the operating temperature is reached, it enables coolant to circulate through the engine, creating a perfectly controlled engine environment.
