Can anyone tell me how to purge the air in the cooling system of my 2001 Dodge Ram truck?

What size engine? leave the cap off and upper hose. Sometimes you will have to remove the water pump by-pass hose and heater hose. There should be another hose by the thermostat that you can take off to purge the air out (depending on engine).
