It should not be necessary for the car to be parked on a slope to get the
air out of the cooling system. First, set the heater temperature to full
hot, remove the radiator cap, and start the car. Let the system warm up
until the coolant starts to rise up to the top of the radiator neck and
the
coolant flows past the neck.. Replace the cap, and you should be good.
If
the radiator cap was not replaced with a new one when the radiator was
replaced or if the radiator cap is aftermarket, try replacing the cap as
well. Also make sure that the coolant in the overflow tank is at least to
the cold mark when the coolant is cold, or the cooling system might suck
air
in as it cools.
