E46 318 m43 losing water?

[ah]

I've had the a brand new rad and thermostat fitted but its still losing water.There dose t seem to be any obvious water leaks but its going somewhere,there's no water in the oil,so head gasket etc can be ruled out,the only other place could be the water houseing unit at the back of the engine.It seems to lose about a couple of pints a week,any other ideas anyone?

You really need to do a pressure test but the plastic elbow at the back of the head is very common for leaks.

[ah]

Cheers for that Barry

As is the head gasket leaking externally in the vicinity of that sad rear water housing
