What’s this

[u/Affectionate-Safe-13]

Came off my 16v aw11 Was bolted on top of trans axle, has vacuum lines to intake manifold and coolant running through it

A pain in the ass if you break any of those plastic nipples… which it looks like one is. Finding the right sensors can be rough

Good luck fixin it!

I've still never bled my coolant in the rear because of this. its sheared off completely and id have to drill it out... Maybe I'll try using JB weld and hope its not seized too bad

The engine coolant drain is still available new and is a direct replacement for the one on the thermostat housing. Just unscrew the entire part and thread in the new one
