Hi out there new to the forum.
I replaced the AOS and had to pause due to work travel, its a pretty strait forward procedure. However after buttoning up intake & both plenums noticed a coolant return line located next to the air injection pump hanging underneath. I missed it somewhere.
Specifically its the smaller line coming out of a T. (Pic attached)
Really appreciate any feedback/help locating its home.
Much appreciated.
