Hey Simon,

No, the radiator cap stays on the radiator. Increased pressure in the =
radiator raises the boiling point. If the radiator gets hot enough for =
the pressure to release the cab then the overflow will go into the wall =
bottle. Once it cools down it's supposed to get pulled back into the =
radiator. Of course, this is a British car so theory and reality May =
differ. But you definitely want to leave a lady in the cop on the =
radiator.

Am I right in assuming(!) that, if one fits an expansion tank, the =
standard cap is moved from the radiator to the expansion tank and is =
replaced by a blanking(?) cap ie one which has no spring, no means of =
relief etcetc? Seem logical to me but logic has let me down before.
