Took my car out today and didn't drive it like an idiot but did give it some welly on a couple of country roads.
When I stopped I noticed the header tank was bubbling-a lot- I heard it in the car - dont remember it doing this before (could have been as I havent driven it for ages)
There isn't excessive pressure in the tank as the cap will undo easily and steam doesn't burst out, in fact it didn't even hiss when opened. There is just loads and loads of air going back into the tank via the top tank hose-only lasts a few minutes then dies down-is this normal please
like I say it could be but seems excessive and dont remember it doing it before.
ps fans are working
