Same problem turned out to be a hair line fracture to the head!
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.

Is your fan coming on?
your thermostat is closed. needs to be replaced. inexpensive part but can save your engine from overheating.
Inoperative radiator fans, bad water pump, failed headgasket?
Water pump defective.
Ingeneral, the fan will run only if the temperature of the radiator is above the normal range. If the fan is running, then the radiator must be over temp unless the radiator fan thermostat or it's relay is defective. If the radiator truly is over temp then you have a larger over-heating problem You state the thermostat was replaced. if you replaced the fan thermostat then either the radiator really is over temp and it is doing what it should, or there is a problem with the thermostat-fan relay or switch. If you replaced the engine thermostat that controls the flow of coolent between the engine and the radiator, then that probably wasn't your problem and you should look elsewhere for an overheating cause. I would start by determining if the engine actually is overheating or not. If it is, I would look for coolent system problems like the engine thermostat (if you didn't replace it already), water pump, leaks, scale build up in the radiator, or blockages in the system. If the engine isn't overheating then I would consentrate on the fan, fan thermostat and relays.
If you have replaced the water pump then flush the radiator with CLR also check to see if the fan is working properly.
I had replaced the water pump and radiator. This had continued to overheat but not as bad. After replacing the head gasket it was finally fixed. I was able to answer my own question only after replacement.
The top radiator hose is above the thermostat. If the top radiator hose is hot, the thermostat is opening. The thermostat is not the problem. Perhaps the radiator is clogged up or the water pump is bad. Look elsewhere.
radiator fan, head gasket,
If you replaced the head gaskets, thermostat, and the water pump and it is still overheating then I would ask about the fan. If it is not the fan, then I would say that you have at least one bad head, if not two. But that is just a guess. A mechanic will pressure test the system and will be able to tell you more. Is the radiator restricted?
