Genuine BMW part 11 51 7 838 159: Coolant pump, mechanical (exchange unit). The number stamped on the part is 11517838159; BMW's catalog files it under the short number 7838159. 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 7831907, so a part carrying that number is the same part. BMW has since replaced it with 7838118.

It fits the E46 coupe and convertible (M3, 2001–2006), with the S54 engine.

BMW draws it on the Waterpump - Thermostat (11_3010) diagram. It weighs about 1.4 kg (3.2 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
