Post subject:  water out of overflow pipe
How are you all going ? I have a problem with a Mk 2 S. Well, maybe not a problem but just an annoyance. When I top the radiator up with water and go for a short drive and stop, water comes out of the overflow pipe. It will do this until the radiator goes down maybe 1 to 1 and half inches from the top and then it is fine and the level stays there. The car was running an 82 degree thermo but changed to a 74. The radiator cap is the standard 13 lb and is new. Any ideas please ? Thanks

This is normal. Water expands when heated and has to go somewhere...> =out the pipe.
Later radiators (eg Clubby) have a level indicator mark inside. Surprise surprise, it's about 1/2 way down the tank.. :wink:

If you `could' (don't try this!) see inside the tank when it's hot, you would find it is full. The air gets sucked back in as it cools, this is normal too.

Everything is normal. The water level is supposed to be about an inch low, the handbook for the Mk1 shows a water level indicator in the radiator and I think the Mk2 would have been the same.
