PS Cooling Setup for Automatic S

[JumpingJackFlash]

The PS cooling fan on my '06 MCS has been grinding with dust/dirt for years. It makes a bit of a squeak sound at times. I want to replace the fan but also do some preventive maintenance since the Germans put down tons of road salt/grime during the Winter months. I have one of the original skid plates from my old '02 MCS back in the states, but I don't want to have to remove it every time I do an oil change. Not to mention it could become a place for fluid drips to collect, and German car inspectors are extremely picky about zero oil leaks (which is why I made it a priority to replace the crank, oil filter housing, and oil exchanger seals a couple of months ago).
