CHEVY ENGINE OVERHEATING

2000 Chevrolet Silverado

Engine Cooling problem
2000 Chevy Silverado V8 Four Wheel Drive Automatic

My buddy has a 2000 chevy silverado 1500 z71, last week it started to overheat, so we went through some steps and put a new thermostat on it it's cooled down alot but when he turns the air conditioning the engine temp starts going up again, what might be other options to check to see what is causing this thank you.

Not much info here (mileage, maintenance performed, how it's driven, etc.) Could be water pump, radiator, cooling fans not working, low or worn out oil (remember, oil doesn't just work as a lubricant, it works as a cooler as well).
