Used as part of a complete cooling system rebuild and conversion to waterless coolant. The tank is high quality and fit was almost perfect. The top mounting screw had to be inserted at a slight angle, but it tightened down just fine. Highly recommend this replacement tank.
Genuine replacement expansion tank for E24 BMW's built from 9/1982
Your BMW's expansion tank is an area in which hot coolant has the room to expand and cool down before entering the cooling system again. Due to the pressure and extreme heating and cooling cylces this part must endure it is a common failure item on older vehicles and must be replaced.
Please note that this newer style expansion tank uses a bayonet style expansion tank cap and not the original designed threaded cap. If your BMW still has the original expansion tank with the threaded cap you must also order a new expansion tank cap, p/n 17111100848.
