Auxiliary water pump on e36!?
Hi! I have a 323ti - technically same as 323i, so it is a m52. Someone of the previous owners has run extra wiring and installed a auxiliary water pump - looks something like 64118390063, but metal not plastic.
As far as I know e36's should not have this.
My question is why would anyone add this and can I remove it - because it is leaking.
