I had to change the head gasket due to antifreeze getting into oil. Since then I cant keep antifreeze in overflow bottle. Car does not overheat temp stays at 190 degrees. But continue to find antifreeze on ground after running and driving. Seems to be boiling out of overflow. I have changed thermostat twice. Can let run in driveway all day no leaks. Have pressure checked twice, no leaks found. Could it be a bad overflow bottle and cap?
Have you checked for a bad water pump or hose.
Replaced water pump with head gasket. Replaced all hoses. Pressure checked system, no leak
