Water pump for Minis with multi-point injection and front-mount radiator. This water pump is missing the attachment point for the alternator, which is relocated in front-mounted radiator MPi models. Fitted with a PPS glass filled plastic impeller, as used by Jaguar and Aston Martin, it reduces weight on the bearing and has a triple lip seal. This pump has a larger impeller, sticking into the block very slightly more than 1/2". Has the rolled edge gasket face developed by Rover for better sealing.
