P.S I forgot one other thing

CHECK THE CONDITION OF THE RAD HOSE BENEATH THE DIZZY!!!!!

Mine had perished so dramatically that there was a very fine, almost see through blister on the inside of the hose where it couldn't be seen!!! Boy, Was I lucky or what that I caught it!!! It was a job that I'd been putting off for ages, gladly now I plucked up the courage to replace it!!!
Incidentally it was the oil dripping onto the hose that caused the damage.
