Changed the stat and a 100% positive that its not leaking but im loosing coolant if I use the heating. But if I freeze my nuts off and dont use the heater I dont loose anything.... so am I right in thinking its the HBV ???
-
at last a genuine post tonight.. hooraaayy ;D ;D
-
is it a fast loss or slow? and i dont suppose you can see it leaking from anywhere under the car? back passenger side of engine compartment if it is the HBV

No, it's definately the Horsebox! ;) ;D
And seriously?...it sounds very much like the HBV :y

Well thank you , kind Sir ;D ;D just cheeseed off that I have to bring the subject up again :-[
-
I'd say not - all of the cooling system is under the same pressure all of the time.
the HBV shuts off coolant flow to the heater only when you have both temperatures turned down as low as they'll go AND the aircon is on. But even then, both sides of the HBV are subject to the same coolant pressure, so would leak at the same rate.

Thanks Phil but I would never pull a horsebox for love or money.... bloody horrible thing

So are we saying it could leak with the heating on or off in the car :-? :-? :-?
-
yes.
-
yes.
Any thoughts as to what it could be causing this leakage then :( :-?

a strong possibility its the HBV, have known them to leak like that before. one of mine did the same. ;)
-
if you can't see it, go looking down the back of the block where the HBV is.
I'm not saving that the HBV isn't leaking, only that the heater setting won't make much difference to the situation.

i wouldnt go for a cheap one, they arent that expensive anyway tbh. ;)

This was exactly what mine did when HBV went on it. I set the heater temp to low just to get me home. If I turned the heater up the water gushed out. :y :y
I definately didn't have aircon on to stop it leaking. It was minus 4 outside when mine went and nearly minus 4 inside without the aircon being on. I turned heater to low setting to reduce water loss. :y

They are when you are skint ;D ;D ;D ;D but thanks all , just needed to assure myself I was thinking the right way on the problem
-
not just me then. ^^^ ;D

have a look on vauxhallworldparts site. :y

don't understand the logic there - nothing happens to the HBV until yu turn the heating right down both sides AND turn on hte aircon. But even then the heater is still filled with coolant at 15psi or so.

No mate but its that time of year I suppose and we all go spending crazy for some reason ::) ;D ;D

There is a lad in farnbourgh ( that Ive used before) that has one for 12 quid posted but Im off to collect one in the morning now
-
just looked on vauxhallworldparts, they dont even have them listed now. :o
-
Local dealer wants 40 quid so I may just strech myself to one from there as its payday next wk

Found this out by accident on my previous Omega V6. Used the car on a summers day and all was fine. It got chilly at night so the heater went up and water gushed out. Next day the sun was out so heater was set low. Very little water loss. Evening came, heater went up and water gushed out so it had to be heater related. Setting to low temp may slow down water loss until it goes completely but it does sometimes give you a fighting chance of getting the car home. :y
