I have a Vectra GLS 1.8 16v 1997.

First of all, what is this and what does it do?



For some reason water is pissing out of this hole, it is draining my coolent at a rate of about a litre every few mins.



Here is the 'thing' from looking front on.



Here it is leaking water.



There is no obvious damage and it hasnt been tampered with.
Obviosuly if i can fix it myself i would rather, can it be sorted? If so how? Can it be bodged? Is it an expensive job?
Any help whatsoever would be greatly appreciated.
Cheers.

I think that that is the valve that switches off the hot water to the heater when the air conditioning is on. There have been ther threads about it.

Try searching for "heater bypass valve", there should be a "how to".
