Thermostat Insert - MAHLE TX 66 91D

This product supersedes product: 6.144.91.351

To operate efficiently while minimising wear and emissions, a combustion engine requires the temperature to remain as constant as possible. MAHLE thermostats and parts are used exactly for that purpose, as they regulate the engine temperature with coolant.

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.
