Coolant Expansion Tank, Genuine BMW - E30 325i 88+ & E36 M3 Euro

This Genuine BMW Coolant Expansion Tank is a replacement part for your aged, cracked, yellowed, or otherwise deformed coolant expansion tank. 

Only for 1988+ models.
 
This part is listed by BMW as BMW part number 17111712641 (17-11-1-712-641) and is described as Coolant Expansion Tank for E30 325i, Euro E36 M3, and Euro MZ3 models.

This tank was also used on Euro E36 M3 and MZ3 with the S50 engine. It can be adapted to US cars but requires the full Euro cooling hose kit and attachment hardware.

This part is also used to convert the 1987 cooling system to the late 1988 E30 cooling system, which also requires the radiator and additional hoses.

This is a Genuine BMW replacement part with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
