Any luck?

I HAVE THE SAME LEAK ON 03 s type 4.2 non s/c. I can trace it to firewall somewhere?? Not at dccv or elsewhere has new water pump, thermostat assembly etc. The tank is fine I already replaced it! ?????? Put dye in and can seem to see it besides in the back not much room to see?? But leaks pretty gnarly after a while??

Hi All,
Thanks Wigginout66 for the info. my thinking is along the same lines... I don't think l'll be able to do much about it before Xmas but was thinking of getting hold of a $15 USB Borescope to confirm this Throttle output pipe is the cause of the leak before taking on the job of removing the Intake manifold.

Merry Christmas to All
and a
Safe and Happy New Year

Tex

You the man I rented a coolant pressure tester and it concluded as to where I was seeing the dye but wasn't sure if there was a hose that went in to the block!!! It sure is leaking from there I'm guessing!!! That hose was a title loose by the TB body but leaking behind the TB so I'm guessing it has to be it! Def not water pump! Thanks and thanks to @mwilliams for his sharing of knowledge on this tricky leak!!! ✌🏾
