I would suspect the thermostat is the culprit. Replace the thermostat. definately replace the thermostat, get a new gasket and all. Also, start the car cold and see if the inlet hose to the radiator warms up evenly. if it gets really hot on the engine side of the hose and is still cool by the radiator that means that there is no flow and either the thermo is installed wrong or something is clogged
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.
My 1990 Honda Civic Hatchback had a similar problem where it overheated on a seemingly random basis. I first replaced the thermostat, but that did not fix the problem. Then I replaced the water pump, again with no positive result. Finally, I replaced the radiator, which fixed the problem. As it turned out, the radiator had pinhole leaks that caused the problem. Also, when it comes to a leaking radiator, I do not suggest the 'quick fix' of additives to the radiator water that plug holes and stop leaks. These additives can cause more problems than they resolve. The best solution is to replace the radiator.

Inoperative radiator fans, bad water pump, failed headgasket?
If you have replaced the water pump then flush the radiator with CLR also check to see if the fan is working properly.
Is your fan coming on?
did you replace radiator hoses i have seen hoses collapse and cause overheating while driving and radiator could be clogged. also did you bleed your cooling system according to owners manual
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.
Radiator caps are pressure relief valves. They are rated at "pounds per square inch" and are designed to release some pressure from the radiator if it gets too high. If an engine overheats it can boil the coolant and this will cause the radiator cap to let out steam. Radiator caps DO lose their ability to regulate pressure and can release too soon. If the engine has not overheated, have the radiator cap tested and replaced as necessary.
radiator fan, head gasket,
your thermostat is closed. needs to be replaced. inexpensive part but can save your engine from overheating.
IF IT WAS NOT OVERHEATING BEFORE THE HOSE WAS REPLACED -- MORE THAN LIKELY YOU HAVE AIR POCKETS TRAPPED IN YOUR COOLING SYSTEM
