Question about 2002 Toyota 4Runner
There are very few cars these days that need bleeding or even have a bleeder. And most of those are rear or mid engine vehicles. Gravity will fill most of the system, then when you get the engine hot, the thermostat must open, because it is lower than the reservoir. The rest of the air will then bleed out and be replaced by water when it cools.
If the thermostat is not opening, it is probably because it is defective or put in backwards. You have to put the heat pellet towards the engine.

Once you are done removing the old coolant refill the system along with the overflow tank. Start the engine with the cap off and continue filling while the engine warms up and the thermostat opens this should remove bleed out most of the air. Once the thermostat is open rev the engine a bit and this should remove any remaining air.
