How do you Bleed air from cooling system of a suburban?

Answer 1

You shouldn't need perform any special tasks to get the air out of the cooling system. Just fill the radiator as much as you can (if you can open the radiator that is, some vehicles don't have a radiator cap) then fill the coolant reservoir to the "cold" mark and run the engine long enough to get the heat up a bit. That will cause any air to expand and push out through the overflow. Turn off the engine, let it thoroughly cool and that should pull in coolant from the reservoir. After the engine has cooled, check the reservoir and add coolant as necessary to bring it up to level. Repeat that process a few times over the next few days and you should eventually get to the point that you're not needing to add more coolant to the reservoir. At that point, the air should be out.
