Hi,

On my 01 2.0 TS 166, the hose from the engine (thermostat) to the heater matrix, as it passes through the bulkhead, beside the expansion thank (visible in the right of the pic), there is the attachment highlighted in the picture.

What's its function? As it's at a fairly high point in the circuit, my initial guess is either a vent for air locks or for use in back flushing the systems.

Can't find a reference to it anywhere. Can any of the brains trust shed any light?

Damnit!

Said little plastic screw has snapped when I was tightening it up! Anyone know where I can get a similar one?
