Thermostat Housing - BMW Forum

I'm looking to replace my thermostat housing. I was looking to replace the plastic housing with the aftermarket aluminium ones. Do you guys recommend I use the aluminium ones?

there isn't much wrong with using an aluminum housing I prefer OEM parts to aftermarket as a personal preference.

Very nice thorough writeup. 1 comment on the water pump. There are 2 threaded holes in the water pump. Use those to thread a bolt in each side and tighten the bolts gradually to drive the pump out. Thats why they are there. With prying you run the risk of damaging the block. Not trying to be critical of your very nice work. Just making a suggestion to help everyone here.
take care,

take care,

Yes I told people to be careful when prying the WP. Yes you are right, M6 bolts will help but not critical because the O-ring sealing surface is inside the hole.
The surface should be protected anyway but read the replies in the same thread.
