I drove my Aveo for 5 miles and noticed that the A/C kept getting warm. When I parked the car in the garage and turned it off, it immediately did white smoke out of the hood. The lower radiator hose had blowed. We replaced the lower and upper radiator hoses and the reservoir hose and filled the coolant with 50/50 DEX-COOL. Then I drove it for a mile and suddenly the A/C quit running and the heat went up close to H. The fan on the radiator didn't run either. So what is the problem? I don't see any leaks.
