btmaldon Posted January 27, 2013 Share Posted January 27, 2013 Sounds strange. Have you tried replacing the expansion tank cap? If its not holding the pressure the coolant could boil at a much lower temperature. Quote Link to comment Share on other sites More sharing options...
fordpartsman Posted January 27, 2013 Share Posted January 27, 2013 i know for a fact that we sell an awful lot of expansion tanks and also thermostat housings for these engines have a look at these and see if there is any wet patches that indicate leaking Quote Link to comment Share on other sites More sharing options...
