Expert:  jazzmaster replied 6 years ago.
hi,there is a small screw on top on the thermostat housing(bleeder screw) while the engine is running turn it counter clockwise until you see water/antifreeze coming out ,dont turn it all the way out,you should see a steady flow coming out then shut it,you might have to repeat it several times to get the air pockets out,also check the cooling fan to see if that comes on at all,that usually comes on around 214-225 degrees (f)If all of that is ok then it could be an upper intake manifold or head gasket problem,,first check the oil and see if it is a milkey color(light brown) if it is the upper intake mainfold is leaking,second if that is ok check for leaks at the front and rear on the intake you would see a small amount of antifreeze leaking,there was a campaign on this ,I dont know if they will still cover it.the last cause could be a head gasket problem,usually a block tester is needed for this ,a way to tell is if when the car is first started that it overheats very quickly   ..guy
