check your thermostat. replace, flush the radiator real good, put new fluild in. should solve.
what kind of fans do you run? stock radiator?

Koyo Radiator and Flexlight and i already did do the fluid stuff

Given, the block/headgasket etc is in good shape.

Air in System, bleed accordingly.

does it still heat up when you put the heater on? or have you even tryed that yet?

Have you ever replace the coolent temp sensor? The sensor between the S13and S14 are different. If you put a S13 sensor in a S14 it always read hot.
If you haven't replace the sensor then I would just do what 420sx says. Also check to make sure your headgasket is in good shape and the head.

Do all of the above and also check that all of your hoses are tightened. Check all of them for any trickling of AF, as that is an indicator of a pressuruzation leak, which also allows for air to enter the system. If an air bleed fixes the problem temporarily, then this may be your problem.
