Engine Cooling problem
2000 Cadillac Deville V8 All Wheel Drive Automatic 160000 miles

I just had the engine, water pump, radiator, and alternator replaced two years ago. The car just started overheating and I took it to the mechanic who replaced the thermostat which was not the problem. The water pump has a small hole in it so that was replaced and the car is still overheating. He did a head gasket check and those were fine. He said there is possibly air pockets. The car only starts to overheat when you drive it. It does not overheat when it is idling and you just sit there. What else could it be?
