How do you get rid of the air in the system of a 98 Pontiac Sunfire after it has been overheating with a new thermostat and water pump?

there are a few ways to do this first look for a bleeder screw

if one is found, run your engine open the screw until the air is

forced out and u see a steady flow of coolant coming out ('''BE

CAREFULL THE COOLANT WILL BE HOT''') If no bleeding screw is found

try running the engine with the radiator cap off '''once again be

CAREFULL with the HOT coolant'''.
