I bought my 1993 Land Cruiser in 2006 with a radiator core that was disintegrating above the bottom tank. The radiator was aftermarket so I replaced it with a TRAD three row copper core from Cruiser Dan when my head gasket went a year later. About four years ago the radiator started leaking while driving and the reservoir would go low every four months. I replace my coolant every 2 years with Prestone 50/50 when I pulled this radiator out it to was rotted and shows signs of electrolysis, are the TRAD’s known for rotting away or could I have a ground issue since I got the truck with rotted aftermarket radiator but I have no idea how well they kept up with maintenance. I’m going to check if I have current in the coolant when I put it back together. I’m putting Koyorad 1918A back in I can’t see paying for OEM if it’s gonna rot out in 10 years.
