Alrite folks, 1st post on this, been reading here for a while and now need some info for myself. Basically I have a 2.0 16v red top in my nova, the water (header bottle) under the bonnet is cracking from the pressure thats building up in it because of the boiling water in it after a run in the car. Its pretty weird this bottle has the normal 2 pipes (1 going into the bottle and 1 going out to the radiator. This is normal aye, like my 1st valver nova. Only this one has another thin pipe bored into it that comes from the back of the head ish place that gives a constant feed of water to the bottle when car is running???? I can hear pressure coming out the bottle when I pull up and when I slacken off you know what happens. Bubbling/boiling water fires out wi a vengence.
Any ideas as to problem and how to repair would be appreciated
Cheers in advance
John
