vauxhall astra 1.7ctdi losing water?
my engine seems to be losing water but no visible signs of a leak , heater blows cold when engine is idling then gets a little hotter when engine revs are up and after a couple days after topping up the expantion tank with water it seems to be dissapearing but i do not see any leaks from anywhere i have checked th oil and there does not seem to be any water in it so i dont think its the cylinder head any suggestions would be much appreciated

Suggested Solution

A presure test on cooling system should show any external leaks i.e water pump etc.Depends where a head gasket goes whether it mixes with oil or not . A block test will tell you if it is leaking for sure or eliminate that .Could also check expansion tank / cap for leaks .
