As I change the radiator I plan to change the hoses and belts as well.
After doing some research it looks like BMW has changed the radiator design which requires an different radiator hose and perhaps a vent cap (plug).
REALOEM provides the following part numbers:
1711 7 585 036 Radiator (new and requires the next part)
1153 7 609 944 Hose Cooler for Engine Oil
1712 7 593 490 Coolant Hose (Requires next 2 parts - Upper?)
1712 7 536 235 Vent Pipe
1712 7 598 004 Cap
1712 7 537 108 Coolant Hose (Lower?)
1712 7 537 109 Coolant Hose (4 way Inlet?)
1712 7 537 101 Coolant Hose (reservoir hose?)
1712 7 555 290 Vent Pipe (recovery tank hose)
Can anyone with recent experience or knowledge confirm that these are the correct parts that I need to replace the radiator and hoses?
Thanks in advance

Doing a little more research would suggest that the last part in my list (No 1712 7 555 290 Vent Pipe) is an older version of the vent pipe that ends with 235 (in the middle of my list) therefore, I shouldn't need the one that ends in 290.
Also, the older "Vent Pipe" (ends in 290) had an additional vent line that use to connect to an older version of the upper hose. Since I am replacing both the vent line and the upper hose with the newer version I will not need the "Cap" (ends in 004) as there will be nothing to plug (those lines will no longer directly connect).
I have contemplated on whether to replace the water pump and thermostat while I have it torn apart but they were both replaced about 30K miles ago so I am hoping I should be OK for a while.
I would appreciate anyone's insights and confirmation on the part numbers.
