After changing water pump, air got into the cooling system. How do you bleed the air out of this engine. There isn't a bleeder valve that I could find. Thanks

Turn the heater on to full hot, so coolant flows through the heater core. Top up the coolant level in the radiator and expansion tank, run the engine when the thermostat opens often air will burp out of the block of the engine run it until the electric fan comes on and goes of, let the engine cool down fully, top of the coolant run it again until the fan cycles on and off and let the engine cool down fully, recheck the coolant level do this until you know longer have to top up the coolant.

This proceedure discussed above is normal for most vehicles.
However there are some vheicles which have beeler screws in the coolant system somewhere that must be bled to purge the air pockets.. AKA,, toyota's, Olds intrigue, Chryslers.
