Motor Emission Coolant Expansion Tank Kit W/ Cap & Sensor For BMW E36 323i, 325i, 328is, M3, Z3, E39 528i – White

If your BMW is getting a little long in the tooth, this is a smart play.

It's a complete coolant expansion tank kit from Motor Emission, and it comes with everything you need: the tank, a new cap, and the level sensor.

Fits a ton of the classic BMWs like the E36 323i, 325i, 328is, M3, the Z3, and the E39 528i.

The tank is white plastic and it's a direct replacement for the original, using OE part numbers like 17111723520 and 17117639022.

It's brand new and durability tested.

Just a heads up, there's a Prop 65 warning for California, but that's pretty standard for this stuff.
