Question about 2002 Mitsubishi Montero
If the overheating is only occasional, it sounds like the radiator still has some blockage that moves around and plugs up again. Try flushing it backwards again. If it continues, consider a new radiator. A radiator is cheaper than head gasket work, which may happen if it keeps overheating.

I would recommend that you bleed all air out of the cooling system. The bleeder valve is located on top of the engine. Once engine starts to overheat or when you can hear bubbling back into the overflow bottle, turn car off and open bleeder valve. If you see bubbling you have air in your system. Bleed the system a couple of times and see if this helps.A heat sensor sending unit which controls activation of the electric fan could also have failed.But if the heat sensor is properly working then check the radiator cap is it properly fitted or got loose.If its loose it will release the pressure and car will overheat.But if the radiator cap is properly closed.Then its time to check the HEAD GASKET.As you have replaced the head gasket still get it checked is it overheating very quickly or is the head gasket placed properly also check the coolant level in the car. Thanks. you can rate this solution and show your appreciation.

Was the thermostat put in backwards? I know this is a silly question, but I've seen it happen. The water pump will fight it if it is. Another thing are the coolant passages, are they flushed out? Also, if that fan clutch is the original one, I would go ahead and replace that as insurance against the water pump breaking.

I would go with slowcalafl. It is either air, or a cracked head bad head gasket. Remove the radiator cap when cool. Start up the car and watch for bubble emerging from the coolant. If it continues to bubble, you have a bad head or head gasket. If not, look for improper timing as another possibility.
