The usual reasons are one or more of the following 1. Radiator cap bad (system must be pressurized to cool properly) 2. Bad themostat 3. Lower radiator hose weak. (at speed, the hose can callopse restricting the water flow) 4. The viscus fan is bad (this is the fan that is driven by the fan belt. It has a slip clutch) 5. Old or Improper coolant mix in radiator (should be 50% water/50% coolant) 6. Radiator needs to be flushed or rodded 7. Timing too high. NOTE: do not remove the thermostat. it is there for a reason.
