Expansion Tank Mounting Bracket - E46 E85 Z4 - Auto Trans
Expansion tank frame for automatic transmission models. Replaces BMW part #17111436251.
The mounting bracket is a plastic frame that sits with the E46 radiator support and gives a mounting location for the E46 expansion tank. The frame itself is not a source of leaks or failures but having a new complete mounting bracket makes changing the reservoir a breeze instead of a struggle. The tank and the bracket are both plastic and will easily crack. Pre-assembling the tank and bracket as a unit means you won't have to struggle with a stubborn tank or broken parts.
On automatic transmission models this base also includes the location for the transmission cooler thermostat.
This is a new Genuine BMW expansion tank mounting bracket. It comes with the coolant connector, o-rings, as well as the locking tab for the transmission oil cooler. A new thermostat is recommended. All parts have a two year warranty.
