Well, tired of seeing the factory tank squashed in the driver side, so im in the process of making an aluminum expansion tank. Will retain the factory style bleeder screw. Internally baffled and going to try to keep the factory coolant sensor as well. Here is a small sneak peak, and will update with more progression picks :).

A little progress. Still waiting for the tap to arrive to make a bung for the bleeder screw. Will be draining the coolant and test fitting in the bimmer this weekend and make some mounting brackets.

I tossed my coolant level sensor on my tank but I like that you kept it and worked that into your design. With the amount of water pump housing cracks on this platform its nice having that warning...

I might be interested. Anything is better than the $600 Turner coolant tank...I am surprised that is the only option on the market.

Yeah me too. The next model will be similiar in shape to the turner, but not even close to that $600 mark lol.

Sign me up. If it retains the level sensor then I’m all in.

It retains factory sensor!
