If coolant is dripping from the weep hole in the water pump, the mechanical seal has failed, and the pump requires a full overhaul or replacing.

This seal, when purchased along with the water pump repair kit should allow any competent DIY mechanic to fully overhaul & recondition the water pump.

NB:- It is not possible to determine what size seal is fitted to any individual pump until it is disassembled, consequently it is important for you to read the extra information pages, to help you confirm that it is possible to overhaul your pump, and to order the correct size mechanical seal.

The measurement of the diameter is taken at the widest point of the aluminium cupped seat.

Choose from either 32mm (Small) or 35mm (Large).
