Is it leaking in the cabin or under the bonnet? Just replaced one today as the pipe stubbs seem to go briitle with age. Done a few now.......

Its had 3 engines in it now and it just seems to loose water.. I have tried rad weld in it, and that stops it for a bit.. Well, until the next time i take the mtor out come to think about it!


I think those pipes are ok though and i cant see any water in teh footwells etc.

you might not see the water as it has a drain in the middle of the housing that drains into the tunnel, its an easy job to take the matrix out of the side of its housing and see if theres any staining in the bottom?

On my old 316 i had the heater hose connection at the bulkead crack and then fail completely emptying the water from the engine in minutes. The RAC guy did a temporary repair that lasted until i sold the car months later and was OK up to the point that the car was written off in an accident. Anyway, the heater connections a re plastic and go hard / brittle with age so it's worth checking these.
