Original radiator? Any buidup of corrosion, sludge? Bits from the waterpump? All the tubes clean and circulating fluid? Look for reduced flow accross the radiator for reduced cooling capacity if the pump is pumping ok.

YEs radiator is the thing to check as they are usually getting plugged internally by that age and need more than a simple flush to cure.

CHeck if the hoses are colapsing
Try replacing your radiator. I just tried chasing an overheating problem all over my '86. Finally I just bought a new radiator and suddenly the engine runs cool and efficient.
I had the same problem with my `86 4x4 with the 22R. I had replaced the thermostat, fan clutch water pump and had the radiator rodded. It ran fine during the winter months then seriously overheated this summer. I bought a new radiator from NAPA and the truck runs fine.
"Rodding out" a radiator is nothing more than a waste of money.... its cheaper just to replace it.
