1988 New Yorker 3L V6- I have replaced my thermostat, flushed the radiator but still it over heats. I noticed under the car quit a lot of fluid coming out and when I looked at the over flow container, it was coming out of an open stem. Is that normal? I loose fluid even driving around the block. Should there be aq cap over the stem? ---

A leakiy head gasket ot cracked head are most likely causes of such a problem. ---

Are you basing the overheating complaint simply on an overflowing radiator? If so, maybe it’s not overheating at all and the radiator cap is weak. ---

If the car overheats, the dash should show a RED light as well to indicate a hot engine.
