On the 5 litre motor there are two small heater hoses that connect to the top of the water pump. One is a very long one that goes down the passenger side of the motor – forget that one. The other one goes from the pump to a T-piece and then branches one way to the water control valve and the other way to a short hose that looks like it goes to the inlet manifold. What I am interested in is the three hoses that go to the T-piece. Does anyone know the part numbers for these beasties? I haven't got a manual and the McKay hose catalogue is a bit vague.
