03 View BMW DiagramSee this part on the official exploded view→This is a genuine BMW expansion tank, part number 17 11 7 573 780. The number stamped on the part is 17117573780; BMW's catalog files it under the short number 7573780. You will find it on our Cooling System shelf, under Radiator with mounting. It supersedes the older number 7787040, so a part carrying that number is the same part.
It fits every E46 body style (316i, 316i 1.6, 316i 1.9, 318d, 318i, 318td, 320d and 2 others, 1997–2005), with the M43, M47N, M57 or M57N engines.
BMW draws it on 4 diagrams, among them Expansion tank, manual gearbox (17_0140) and Expansion tank, automatic gearbox (17_0141). It weighs about 820 g (1.8 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
