front of the radiator can plug up with debris, bugs, cotton from driving. take off the radiator upper retention plate, and look in between the radiator and the AC condenser. Blow out with pressurized air. Other than that, you could have an air bubble in the cooling system. Check all your fluids -- make sure oil pump is working check electric fan if equipped.
