My car only overheats in slow traffic. Changed the thermostat & radiator. Hoses and gaskets look fine. Dont know a thing about a hydrolic fan but it stays on when I run the a/c. A/C blows ice cold all the time even when I try to adjust it. The reservoir level stays full & bubbles but will empty when I lift the air release valve. The car cools off pretty quickly once I've stopped or speed up again. What could be causing this?. Amy in austin :

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, Pressure test the Rad. Cap, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.
