Join the club. The list of aches on my '02 530i is even longer. I'm at 44k
miles right now.

Likewise. $4k spent last year.

Do you own work? That can save a bundle, but the OEM parts come dear. The
door seals weren't too bad once I figured out the directions I had for the
trim panels weren't quite right. Even with the Bentley Manual and ETK/TIS
it's still an adventure and I'm a fair-to-middlin' mechanic.

My '03 530i (35Kmi) has had the instrument cluster pixel problem (repl
under warranty), and gets fluid replacement per the old maintenance
schedule. Only other problem was a scrambled computer (don't know which
one) that left central locking inoperative, headlights on, and no start
condition. Momentary disconnect of battery, while waiting for BMW
roadside assist, reset the computers and fixed the problems (try it,
you'll like it). Now that it is out of warranty the CDV will be disabled.
Question about pre-emptive radiator replacement. My independent mechanic
says not to use an upgraded (aluminum) radiator because then an
overheating scenario (eg failed water pump) will blow a head gasket
rather than the new, sturdy radiator. The only failure I can think of
that would use the radiator as a "fuse" is a stuck shut radiator cap.
How likely is that?

I did the CDV early and used a gutted valve as a (stealth) replacement. A
subtle but nice mod. Good time to flush the brakes and clutch with new
fluid too.

If I understand his logic, an overheat would be minimized by
overpressurization, subsequent failure of the radiator, and steam venting
from the failure thus delaying damage? Don't think so. If the temp does a
quick move to the red, you need to park it asap (I'd check my mirrors and if
clear, coast to the side of the road, clutch disengaged and with ignition
off as soon as practical). I don't think a catastrophic radiator failure
(typically a cracked hose neck) will have any less impact than a failed
water pump.
Excessive heat quickly warps and can crack the head. The head gasket
promptly fails. I don't think it much matters what causes the rapid heat
rise. V-8's are notorious for early cooling system problems, I-6's less so.
I think a move to the Zionsville cooling system and Stewart water pump make
good sense (leaving only the OEM thermostat and housing ... they make an
aluminum housing for the M-52 but not the M-54), but they're about 2.5 times
OEM price. Maybe worth it if you plan to explore the 250-300K miles region
of durability. Otherwise better to go with OEM parts around the 75-90K
range. Or you can just hope that the system won't fail (many last into the
100's) or if it does, you'll catch it in time.
