Bleeding the Radiator

I'm replacing the radiator & lower radiator hose on my '94 Plymouth Acclaim. Whenever I'm done though i was wondring how do i bleed the air out from the system. Is it as simple as just running it for a while with the radiator cap off? If so how long do i let it run?
Thanks in advanced, Jim

You can jack up the front end to where the radiator filler is the highest point in the system. Fill with coolant. Then run the vehicle until the temperature goes to normal or high normal temperature. Shut vehicle off and wait for a few minutes. Top off coolant and repeat. This should get the air out.
Being way2old is why I need help from younger minds

ive also found it helpfull to put the cars HVAC on full heat. for two reasons. it allows coolant into the heater core and gets any trapped air out.
also the heat of the air coming out of the vents is a good gauge of air in the system.
if you have a constant HOT not warm flow of air out of the vents your good to go. you will see as your bleeding the system the air from the vents will be cold, warm, cold again, warm, HOT, warm, HOT..
and thats just the air pockets circulating through the system working their way to the highest point which should be your open radiator

Jumping in here: Metal are at an all time high. Ask at even junkyards as I see them advertizing for old household appliances and high prices for junk cars in any condition!
Copper, converters, aluminum and more are precious metal and worth $$ in many cases now,
