BMW E36 M50/M52 Coolant Expansion Tank 17111723520

Suits all E36 6 cyl variants. It is recommended you replace your expansion tank when refreshing your cooling system. Due to their design, they are known to stress fracture causing leaks, overheating and potentially leaving you stranded or worse, engine damage. A faulty expansion tank also prevents your cooling system to be bled properly after coolant changes.

Good practice is to replace your expansion tank along with a new cap and bleed screw for peace of mind. Check our store, we also stock caps and bleed screws for these expansion tanks.
