2010 ford Taurus keeps over heating, oil cap doesn’t have milky residue and the dip stick either , fans are working , I took off the thermostat keeps over heating , bought a new thermostat and keeps over heating bought the cap for the antifreeze reservoir and keeps over heating , I don’t think it’s the head gaskets what do the experts think ? I also tried blue devil gasket sealer and it over heats still ! The crazy thing is it’s ok for a few days and then it over heats again oh I almost forgot I also changed the temp sensor and it keeps over heating any advice ? Thanks in advance car work good and everything just keeps over heating any tips are appreciated I’m all out of ideas thanks
