I have 1989 Toyota Truck 22re 4x4 5spd that runs hot after hot after a highway run. You can hear that the water is hot and boils over into the catch can. In the city with AC running, it will run about 3/4 after a long drive.
The engine idles and runs smoothly throughout the operation range.
What I've done are:
Set the timing
Check the plug gaps
Adjusted the rockers
flushed the engine
Replaced the pump
Replaced the cooling hoses
Checked for vacuum leaks - none
I have installed a OEM head gasket and had the head refurbished at local machine shop
So, I'm thinking it could be the radiator. I checked the radiator while it was hot and there were areas on the cooling fins that were spots on the radiator where it was much cooler...?

I see the ongoing discussions about all metal (brass/copper) vs Aluminum (plastic/aluminum)
I am looking at going with stock but BIG$$$ vs Aluminum $$
Therefore, I am looking for suggestions on what radiator to use
