Replaced PS fluid reservoir/filter and hose to PS pump.
Meyle Brand Power Steering Reservoir Mini BMW E36 E38 E39 E46 E60 E63 X3 X5 Z3 | eBay
The OE hose had been leaking at the base of the fluid reservoir for years and I finally dealt with it.
Hose PN: 32416758958
Kind of a PITA getting the OE clamps off and then the residual fluid in the reservoir spilling all into the engine bay :pull hair:
While I had the lower pan cover off, I also changed the radiator drain plug, whose o-ring had begun to develop a slow leak.
Fresh AMSOIL Synthetic ATF fill for the PS.
All dry now
