Coolant Leak Under the Intake Manifold

Bringing this to the top please.

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.

Out of curiosity, what did your shop charge for those repairs? I'm looking at the same issue with my '03 4.6is after recently replacing the timing chains and guides and rebuilding the VANOS myself. It can't be more difficult than that task!

Thanks in advance,

Robb

Rob, the 04 has the N62 motor, you have the M62. No "Y" connection on your motor. As I put in the other post, just pull the intake and you will see everything right away.
