Thermostat — a genuine BMW part, number 11 51 8 588 945. The number stamped on the part is 11518588945; BMW's catalog files it under the short number 8588945. You will find it on our Engine shelf, under Coolant pump with drive. It supersedes the older number 8577896, so a part carrying that number is the same part.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on 6 diagrams, among them Cooling system - coolant pump/thermostat (11_5592) and Cooling system - coolant pump/thermostat (11_5751). It weighs about 90 g (0.2 lb).

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