I've checked the coolant, leaks, radiator, and tried replacing the thermostat. There is something malfunctioning that cannot be seen. Any suggestions?

Thank you for the reply. I have a clutch fan and its good and tight. We had bought a brand new thermostat but I will test it to see if its good. I'll let you know how it goes. If you have any other ideas please let me know. Thanks again.
