My Indy just did my 2004 4.4 coolant pipe.
He said those y pipes ALWAYS break when removing intake.
As for your coolant leak can't say for sure the source.


IMO you might as well continue with the collapsible replacement coolant pipe
now. If it's near 100K, it's done. Not a cheap repair, but it's a one and done
modification. You are 3/4 of the way in there.
