Quote: He verified that his radiator is doing it's job. There's no need to look at replacing it. He needs to find the source of the heat.
A loose converter dumping trans heat into the radiator or blown head gasket would easily cause that problem.
I wasn’t suggesting he replace his radiator. I know he said he had good a temperature drop cross the radiator. I was just relating a similar experience with my car hoping it would help him out. I also had a 30 degree plus drop across the radiator but it still wouldn’t cool. When I installed the new radiator and electric fan I left everything else the same. I am convinced even though the three core radiators fin design was inferior installing the electric fan is what cured my cooling problem.
