Hello again folks...
After a run round the city centre today, when I parked up I decided to check under the bonnet with the engine on tickover (to listen to see if the hissing noise was any worse - as per my other thread).
Anyway, for some reason :-[ I decided to take the cap off the coolant header tank (slowly I may add!), and coolant came shooting out of it! :o Anyway, I obviously put the cap back on sharpish...
Is this normal? It's never happened on any other motors I've owned?
I'm getting a bit panicky now - could this be a sign that the HG is on it's way out?? :'(
-
I would think that is normal, as the coolant pressurises when hot.
-
Phew - ta for that!
It's just that I've already experienced wallet-crushing HG failure in my last motor recently, so I'm a little bit on edge...

Every car I have had did this if the engine was still hot..... at one time it used to say on top of the caps don't undo until cool.. so I would say that this was right. :y :y

Removing the header tank cap when the engine is hot is potentially dangerous. Pressurised coolant has a much increased boiling point, and has the potential to 'boil' immediately the pressure is released, with exactly the result which you experienced. You were lucky not to get scalded!
