I recently changed the fan, expansion tank, water pump, thermostat and radiator and its been fine since, but is had this issue for the last 2days, any suggestions would be appreciated! Thank You.
Did you follow the proper bleed procedures on your cooling system after such a major overhaul?

Did you check your fan/clutch is it operational and within RPM range.
Sounds to me that it's not drawing enough airflow through the radiator based on your description...

Are you using the A/C?
