Engine radiator OEM BMW or Nissens

Best one to get is the Nissens 68001A. I just put one in my 2000 9-5. For some reason Rock Auto only lists it as fitting 2001 but it will fit a 1999-2001.

Im going to be replacing my radiator soon with all coolant connection and hoses, does anyone know the difference between the radiator std and heavy duty one? STD: Nissens #652011 Heavy duty: Nissens #65011

The Nissens number is 65264 which is what I eventually ordered.

I was able to shove a cabriolet (nissesns brand) in there...it's stuffed all the way to the left. anyway, it keeps the 1.8t cool without any issues

No worries with the nissen branded radiator. I have installed tons of them into mk3 vr6 cars over the years with no issues. They fit perfect and the quality is very good. I have a mk3 fitment nissens branded radiator in my a2vr6 also that I installed a few years ago. It cools the car perfectly fine on both the street and the drag strip.

For better flushing I have also been removing the upper radiator hose and using my garden water hose to flush the radiator (a Nissens radiator I installed half a dozen years ago after finding a leak in the factory radiator).

I had an older BMW myself (E36) and if you want reliability you'll need aftermarket (improved) radiator, radiator hoses and water pump.

A few things in this pic make me gag, the FRAM filter and cork VC gasket. Not a fan of Castrol oil either, but it isn't the end of the world yet. The Nissens radiator is a nice product, I've used them in the past of other European vehicles.

The white tank has never been the issue for me, leaks are always in the radiator frame surrounding that tank. Somewhere at the bottom, probably where the lower hose goes. The plastic is brittle crap and it develops micro-fractures that become cracks over time.
