hmm, bought a replacement rad for $200 with shipping and it took me 1/2 hrs to install. Runs cooler than with the OEM part. But, I guess, I'm not quite as whacked as most MB owners...
I guess I committed a blasphemy by REPLACING the bad part instead of spending $$$$$ on unnecessary repairs. Stupid me...
