Overview
Electric water pump Pierburg 702851200 circulates coolant through the engine cooling loop independently of crankshaft speed. Operating on 12 V vehicle power, the assembly features a composite housing with an integrated aluminium mounting flange and an electronic control module for rotor speed regulation. Inlet and outlet connection diameters measure 32 mm and 38 mm, with power draw reaching 200 W. OEM cross-reference numbers include 11517586925, 11517563183, 11517546994, 11517521584, and 11537549476. The brushless canned-motor design eliminates dynamic shaft seals, reducing internal mechanical friction while maintaining precise coolant temperature control across all operating states.
Fitment covers BMW 1 Series E81, E82, E87, E88, 3 Series E90, E91, E92, E93, 5 Series E60, E61, F10, F11, X3 E83, F25, X5 E70, and Z4 E85, E89 models fitted with 2.5 L and 3.0 L N52 or N53 petrol engines produced between 2004 and 2016. Replacement becomes necessary when encountering engine overheating, stored OBD2 fault codes 2E81 or 2E82, radiator fan running at maximum speed continuously, or lost cabin heating output. Unit replacement restores standard cooling system operation when original components suffer from housing cracks, internal graphite bearing wear, or printed circuit board electronics failure.
