The part below snapped off the bottom of the thermostat housing today! It connects to a small pipe.

It looks like it should be number 20 from here...

But it is not listed. Any ideas what this part is and how I might get one.

But the housing is fine - it's just that little 'L' shaped bugger that's snapped!
Are they not a separate part?

The Small Hose which supplies Coolant to the Throttle body, I think, comes off that pipe. New Thermostat Housing I suggest, would be the answer.

Can you tell if 320's have the same thermostat housing as a 325? M20 engine.

/\ thats useful.

As said its part of the housing they corrode internally hence why they break off now. Its a lack of coolant changes that does it. Most second hand housings are similar. New one is the best fix really.

Get the hole tig welded up is another answer, then block off the pipe coming from the back of the block with a bolt. M8 thread i think. Its the pipes that head the TB, waste of time.
