i thought the pipe for the hbv had popped off....
i looked to swap the hbv today....only there's no hbv
the heater bridge was going directly to the heater matrix and heater matrix to the coolant tranfer pipe and the bottom connector (on passenger side of the rear of the block)

i'm in the process of putting a hbv on buuut.. i cant see a vacuum pipe for it! ?
can anybody shed some light on it?
thanks

I could well be wrong, but I thought you only had a HBV if you had air con fitted?

i thought they all had hbv's to direct the hot water through the heater matrix to warm the air or otherwise direct the way straight round to the coolant transfer pipe

looks like from the heater bridge or just below on the back of the engine, header tank is pretty much empty!
