Unfortunately the plastic rads are made from that biodegradable composite material. So over time, temp extremes - "plastic" tanks get brittle and crack, or the neck of the tank breaks off like it did for an e30 I was working on. However, depending on the break, age etc. You can fix it. I took an aluminum pipe, cut to desired length slipped it in with some Gorilla expoxy; then put the broken piece back on and clamped it. Came out better, stronger and I can re-use it. A new rad is in the range of 200-400 depending on model and who makes it. Oem is the the way to go...but I'm sure they get quite pricey.

I think I've had 18 bmw's in 6 years.
