Two months ago before joining this board, I replaced the radiator on a 190E 2.6. I got a rebuilt radiator that fit perfectly and looked brand new, for only $125. I got it from Reseda Radiator in Reseda, CA. They charge a $75 core charge which you get back when you return the old one. They shipped me the radiator UPS 2 day to MA for only $30. You can check them out at resedaradiator.com. I have no affiliation with them; they just havea a great deal.
