5.0 coolant leak

If you have a coolant leak at the y hose for the intake manifold and the thermostat, make sure you replace the upper radiator hose as well as the y hose. Ask me how I know.

The o-ring on the upper radiator hose will not seal to the new y hose. There is a seal kit available for the upper hose from what it looks like.

Very old thread. I have the same leak, do you happen to know the part #'s? And replace both the hoses and leave the Y?
