Could be...


Thermostat.
Radiator Cap (bleeding presure into the overflow).
A blockage somewhere in the radiator.

I would flush the radiator / block, and change the thermostat and radiator cap and see if that fixes your problem before looking at much else. You can spend hundred chasing cooling problems (like I did), when in actual fact it's usually the $5 parts that fail and are the cause of the problem (mine turned out to be the water pump).

Good Luck!
