New housing for the thermostat on BEW engine TDIs.


Locking tabs make installing the thermostat and housing easier, but, they are not necessary as they serve no purpose once the thermostat is installed.  Many aftermarket thermostats do no support the locking tabs, either.

Bolts that secure this to the block are one time use. Available below.
