anti freeze coming from radiator cap while trying to bleed system. the heater core is blocked off or bypassed into a t. and have replaced t stat and water pump and oil filter gasket, runs half way on temp gauge but starts to over heat beacuse of water coming out of overflow on radiator cap while bleeding .I have followed the directions on bleeding at least 6 times ..no luck.also new radiator cap and serpintine belt.HELP11

Did you leave enough room in the over fill tank for this to happen because it is going to backup before the thermostat opens that is why you have to leave enough room in the tank for this to happen. Just fill to fill mark with anti freeze in over flow tank and leave cap off once t- stat opens anti freeze level will drop in tank add more anti freeze to fill mark then put cap back on.

thanks i will try that now

worked i also took old cap for radiator and cut the end off and put cap on it bleed in 5 min.
