Coolant System - how to check etc.

[Joeh]

LOLOL!! You are not ment to touch the expansion tank. The reason the expansion tank is there is if the coolant pressure is above the 1.3bar or 0.9 (depending on the cap you have), boiling water will be pushed into there... temporarly, usually sucked back in once the car has cooled down.

You shouldn\'t ever need to touch the dipstick of the expansion tank.

Any help?

There is wires crossed Here, If you refill an Empty System you should fill from the engine and Not take the AST tank top off (so there is no water going into the Overflow)

On day to day Driving you should not take the Engine or AST top of unless the buzzer goes off (but some people check it once a Month to be on the safe side) BUT!!! you should mark the Dipper in the Tank (Drivers wheel well) and keep a good eye on that (Check it often) and make sure it does\'nt rise or fall from where its Marked.

Is there any way of draining the overflow? If the systems been topped up when it was only sitting at its level but then filled to the to a few times, then the waters been forced into the overflow.

the easyest way is to take it off but you can drop the level by getting a peice of hose pipe about 12" long with two clean cut ends then dip it in the tank and block off the end with your thumb whilst the pipe is touching the bottom of the tank , lift it out and take your thumb off the end. This way you can drop the level but if you need to take alot out it may take some time.
