01 View BMW DiagramSee this part on the official exploded view→Coolant pump, mechanical (exchange unit) — a genuine BMW part, number 11 51 1 406 650. The number stamped on the part is 11511406650; BMW's catalog files it under the short number 1406650. BMW's catalog calls it “Exch. coolant pump, mechanical”. You will find it on our Engine shelf, under Coolant pump with drive. It supersedes the older number 1402427, so a part carrying that number is the same part. BMW has since replaced it with 1405720.
It fits the E36 sedan, coupe and convertible (M3, 1995–1999), with the S50 engine.
BMW draws it on 2 diagrams, among them Waterpump - Thermostat (11_1321) and Waterpump - Thermostat (11_6035). It weighs about 1.7 kg (3.7 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
