New Member with 5.6 Liter engine problem!!

[dolarmaker]

I have a 2004 GMC Yukon with a 5.6 Liter Vortex engine that is gradually starting to overheat. Had the water pump replaced in the last year, oil is clear, fluid in radiator is clear and green. Could this be a sending unit problem or what am I overlooking????

did you have the thermostat replaced?
Any coolant leaks?
Did you burp the radiator when you put coolant in?

proly air in the system, but if you did all that work the thermostat should have been a given
