With my 1997 Intrepid. you must remove the air from the lines while filling
coolant to proper level.There's a bleed valve right in front of the
engine,at the end of the upper radiator hose where it connects to the
thermostat housing. Loosen it untill there's a little flow coming -out
bubble free.. (while engine is running). After that tightened the bleed
valve. Good to go!
