Defective cooling fan, blown fuse, thermal relay. Turn on A/C, if fan is not working check fan, relay, and fuse. It could also be a bad radiator cap or stuck thermostat, it is realtivly easy/cheap to change the thermostat and get a new rad cap (preferably dealer). When you change the thermostat look into the radiator to see if the passages are clear, if not have the radiator power flushed or replaced. The orange Dex cool fluid can gum up after a while expecially if it was mixed with green coolant. Hope this helps. "G"

It is not wise to drive with a blown head gasket. If you continue driving with a blown gasket, eventually your car will over heat and the engine will seize up. This can cause accidents if it occurs while driving.
it might have a sticking thermostat.
If the Yukon engine has high rpm while driving, check the transmission for slippage, that will cause the engine to over rev. The overheating could be caused by the high rpms.
