there isn't one.
It is not necessary to bleed the coolant system. If you mean "drain" the system, there is usually a plastic plug on the radiator or, you can pull the lower radiator hose off.
on the top radiator hose.
open bleeder on engine by the upper hose outlet.
It is hidden on the intake near where the upper radiator hose attaches.
Next to the coolant reservoir... black hose sticking forward with a plastic screw in it...
Be sure the coolant reservoir is full. Be sure the hose and hose connections between the reservoir and radiator are good and tight and the radiator cap is good. Be sure that the rest of the coolant system is in good shape (no radiator leaks, no leaks anywhere) and the system will bleed itself in time.
where the upper radiator hose connects to the engine you should see a little bleed bolt
On a GA16DE motor the coolant air bleed plug is on the intake. Follow the upper heater core hose to the intake manifold. The plug is located at where the hose connects. The plug will be labeled,(never open when HOT), from the factory. You might have to clean the area to find label. It is a 10mm bolt.
Try squeezing the upper radiator hose VERY HARD and VERY FAST with BOTH hands. Repeatedly. This will often force coolant into the engine and result in forcing air out.
It's up on the thermostat housing. Follow your upper rad hose to the thermostat housing.
either radiator or pressurized reserve tank. or a coolant hose high on engine will bleed the system for you too.
That engine has to be refilled with coolant in a manner that allows the air to escape. There could be air trapped in the cooling system from not having it filled properly after the radiator was replaced. Here is the way to get air out: It would be good to start with only a partially filled system. Open the drain cock of the radiator and collect coolant fluid. It may not begin to outflow very much until you notice also that the thermostat housing has a bleed valve which if you open it will allow the fluid to drain from the radiator more rapidly. Drain about 3 quarts of coolant in a pan for reuse; then close the radiator drain cock. Put a 4' length of clear plastic hose on the thermostat housing bleed valve nipple and direct the hose over the front of the car to a clean container to catch the coolant as you refill the system (You don't want coolant to get on the drive belts). Then take the cap off the recovery bottle and slowly fill the coolant recovery bottle until fluid starts to flow out of the clear hose. While adding coolant slowly as necessary to keep it running from the 4" hose, gently squeeze on the top radiator hose until all the air is exhausted from the system via the bleed valve hose. The outflow from the hose should have no air showing up. Close the bleed valve and fill the system the rest of the way until it reaches the to the mark on the side of the overflow bottle. Remove the hose from the bleeder valve nipple.
