what maintenance items while core support/radiator are out?

[petebert]

Picked up a 05 X5 3.0 with 120k miles. I do all my own repairs but am coming from the VW/Audi world. This is my first BMW. I acquired it with some front end damage so I've already pulled the bumper and core support off. Going to replace the a/c condenser and probably the radiator.


What type of things should I do while I've got easy access to the front of the engine?



The obvious are the accessory belt, tensioner, etc.. Figured I'd do the water pump. I'm highly tempted to do the a/c compressor because the condenser got a hole in the accident so I don't know if the compressor works. I've got a guy who does compressor rebuilds for good prices and I'd hate to put everything back together and later find out it doesn't work. The plastic engine fan took some damage so I'll be doing the fan and I figure I should replace the fan clutch too.



The power steering reservoir is covered in crud, I've heard this is common? Should I just replace the reservoir and clamps?


Headlights- they appear to be self leveling, does that mean Xenon?


Do you guys have anything like the VCDS/Vagcom software we have for VWs?


I will be buying a Bentley manual.
