07 View BMW DiagramSee this part on the official exploded view→This is a genuine BMW O-ring, part number 11 53 7 501 777. The number stamped on the part is 11537501777; BMW's catalog files it under the short number 7501777. You will find it on our Engine shelf, under Thermostat and coolant lines. It supersedes the older number 1712042, 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 3 diagrams, among them Cooling System Water Hoses (11_2267) and Waterpump - Thermostat (11_2300). It weighs about 1 g (under 0.1 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
