I'm about to pull the trigger on a brand new cooling system, with the only thing still up in the air being which radiator to get. I've searched and read all the previous threads, but was wondering what the general consensus was now.

Thanks

Behr is MUCH better than Nissens. Behr is who makes the originals for BMW. Steer clear of GEBA water pumps too, you should be fine if you stick to those 2 rules regarding the cooling system.

I posted the entire cooling system here (I use Nissens rad and Hepu WP)

Really? Now I'm confused again. It was my understanding they were both pretty much the same radiator but with the nissens having more ribs on the neck? Anyone else care to chime in?

Nissens fewer ribs

In my 528i write-up above, I use Nissens.
Nissens has fewer ribs than Behr.
The theory is the more ribs the more chance of neck breakage (the ribs may the plastic wall thinner???)

Anyway failure of cooling system in the V8 is IMHO due to high temp (I6 engine runs at88-92 deg C; V8 runs a hotter thermostat)

If I were you, I'd do the cooling system every 50-60K on a 540i and every90-100K in a 528i.

The Behr isn't much better than Nissens. They all crap out about the same time. I installed a Nissen Radiator recently and the quality is comparable to a Behr. The price on a Nissens radiator is slightly lower than Behr.

If you plan to keep your car for a while I would get the aluminum one from Zionville. It cost a lot more, but I suppose they do last a lot longer.
