My mechanic is Danish. He says Nissens, a Danish company, can't build a radiator. Use only Behr.
FWIW, contact Reseda Radiator (http://www.resedaradiator.com
) For $125 they can give you a rebuilt (new tanks w/neck reinforcements), rodded, flow and pressure tested radiator.
Most likely, yours is in stock. Otherwise, it's a one-day turn-around if call ahead.
I did this for my 500E and it is keeping the temperatures under control now. Sure beats spending almost $400 for a new Behr.

BTW: run 60% distilled water, 40% MB antifreeze, and one-bottle of Redline Water Wetter.
Don't every run 100% distilled water. It is corrosive at 100%!
