2000 Chevy venture van 3.4l still over heating, after replacing thermostat, radiator cap, fans work properly. Checked relays and all seem to work properly. Van Idles fine, then will get to normaol temp. And all coolant will go into overflow tank. Using temp gun on thermostat housing, block, water pump all temperatures seem normal (ie thermostat 180-220, water pump 150-160) not sure what to check next.
