Designed specifically for the EA839 platform, this direct replacement eliminates the common failure point of the factory plastic thermostat housing. Upgrades/Replaces OEM Part: 06M121115P. 

The thermostat is replaced during a water pump replacement to prevent future failure. The EA893's water pump is a common failure which causes coolant migration. This results in a compromised vacuum system which leads to overheating and under boost issues (P0299).
