Post subject:  Cooper S Heater Tap

Hi,

I have an angled type heater tap on my cylinder head and was wondering, what position is open and closed, and is it better to leave the valve open or closed.

Thanks

Roc

When the leaver is away from the body, it is open, water flows and should bring warmth to the cabin.

I wouldn't recommend leaving it in either position for extended periods. Try to operate it at least once a week.

Actually isn't there a few types of taps, my car had a later (incorrect) tap fitted so that toward the front of the car is off, so pulling the knob in the car turned it on and you got heat.

EDIT: So my understanding is MKII had a tap that operated in this way so that pulling the heater knob out turned the heater on.

Mine looked like this...

However the early taps are the opposite, thats why the heater knob on earlier cars (eg MK1 Cooper S) reads "PUSH HEATER" so that the heater is off with the knob pulled out but pushed in (tap lever toward front of car) you get heat.

They usually look like this....

Thanks for you help in clarifying this. I actually did a cooling system flush today and it operates as per your comments.

No worries. If the tap is a bit stiff and hard to operate someone told me to take it off and soak it in Coca-Cola. :shock: ...and it worked!

Probably because the coke disintegrated the rubber seals and now it has no friction! :lol:
That stuff eats everything.
