Oil Cooling Thermostat - MAHLE TO 1 83

This product supersedes product: 1.248.83

The oil temperature in automatic transmissions is regulated by transmission oil thermostats. This shortens the warm-up phase considerably and the transmission is subsequently kept at an ideal operating temperature. The result: reduced wear, improved gearshift comfort, and fuel savings of approximately 1% in conventional driving cycles.

Although thermostats are not standard wearing parts, there is considerable demand for spares. Whether due to an accident or as part of repair or maintenance work that requires access to the cooling system: these important temperature regulators should be replaced at that time to ensure continued functionality, because any loss of functionality or even complete failure can have severe consequences. If the thermostat is always open, the engine will be cooled too much. If the thermostat is always closed, then the engine will not be cooled at all and will overheat.
