Hi All,

Last week i noticed that my heaters was cold and the coolant in the expansion tank was low.

I topped this up with about a litre of water did about 40 miles and it was low again. I cannot see any visible leaks,Checked all pipes etc theres no white smoke coming out of the exhaust and there is no water in the oil as its still nice and black.

I checked it this morning before starting it up and the coolant tank was pressurised whether that makes a difference.

It can evaporate before you get to notice

only leaking under pressure

Damn stuff is going somewhere, get a loan of a coolant pressure tester

Saying which, you HAVE put coolant in and not just water?

That is a fair amount

Do not put just water in it, you'll bugger it

Are the front footwells wet?

Is the rad hot all over?

Does the top get 'hard' when up to temp?

You need a coolant pressure test

must be leaking from a small hole or wear point
