The big fat one that goes from the bottom of the radiator (on the left looking towards the car). Mine's leaking at the joint where a smaller pipe comes off towards the carb - can these be bought new or would I have to faff making my own?
In other cooling news I think our fridge needs re-gassing, temperature won't go below ten despite the pump constantly being "on", and this won't be helped by that our lodger is now back here and insisting we have the CH on 25degrees... Grrr
