1996 Ford Taurus wagon 6 cyl (2.3l I think) A problem for over a year & I really can't afford to have the Ford mechanics guesstimate it. When moving the temp runs about right. When in mediocre traffic, it gets real warm but doesn't overheat. When in stop & go, it gets hot. Once moving, it returns to normal. Winter or summer. No leaks. Already replaced the thermostat. The fans are turning. It's been flushed.
