Coolant Leak
2000 F150, 5.4L
My serpentine belt disintegrated a couple miles from home, and, perhaps not so smart, I limped on home. By the time I got there the temp gauge was pegged. I allowed engine to cool off and replaced the belt. Next trip I discovered I was losing coolant. At the front of the (plastic?) intake manifold is an aluminum crossover which supports the thermostat housing on the driver's side and a heater hose port on the passenger side. The leak appears to be coming from the mating surface of this crossover below the heater hose connection. I assume there is a gasket or O-ring of some kind at this location although my Haynes manual is unclear on this point. Question: Does replacement of this gasket require removal of the intake manifold? Thank for any help.
