01 1.9tdi coolant problems - bondwithme
Hi,

my coolant level drops from max to min when the car reaches operating temp and stays there unless you release the cap then returns to max also has stored pressure for 24hrs or more any ideas I have replaced the stat, temp senser, & coolant so i am stuck fans never keep in but car never over heats + rad stays cold

Help pls the coolant thing is the opposite to what it should be


thanks

Sounds like an airlock.
Try searching for a solution but use the VW engine, they are all the same.

Sopunds like head gasket leakage pressurising the system and blowing water out of the overflow. Providing it doesn't drop below minium I wouldn't worry about it for the time being.

Peter, its not blowing out coolant as the level goes back to max when pressure is released. No water is lost. Dont sound like HGF to me.

IF the system is not loosing coolant then it sounds like air in the system.
Take it to a garage where they have a vacuum coolant filler (lots of places use these now) and get them to refill the system for you. Make sure they use G12 or G12+ coolant.
