| also, belt tensioner is a big thing as well if it's never been replaced to keep good tension on all the accessories that run off that belt...
I spent HUGE money on my cooling system, but with all the horror stories I hear, especially with the e36, and my track time, it was WELL WELL worth it..
IMHO... every cooling system should do the minimum every 60K-70K (i've personally replaced a OEM radiator with 48K on it, *cracked at upper neck*)
radiator (if OEM) otherwise Mishimoto alum or higher, and never worry again
thermo (88C or 80C if you track/hot weather area)
alum housing (only once, just make sure you have it)
hoses (upper/lower)
expansion tank/bleed screw
water pump every 80-100K (stewart water pump if you track/hot weather area, and the stewart has lifetime warranty IIRC)
coolant flush every 2 years or 1 year if you track
new fan (euro diesel preferably, or fan delete with electric even better) |
