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.
This bracket is for manual transmission models only.
This is a new Genuine BMW expansion tank mounting bracket. It comes with the coolant connector and o-rings and is ready to install. A new locking tab for the expansion tank is recommended but not required. It has a two year warranty.
