Here are some pictures of how mine cracked open on the bottom side of the plastic fitting.
I dismounted the main wiring loom from the bracked on the intake manifold and pulled it out of the way.
I dismounted the IMRC valve and pulled it out of the way.
Then went to work with a pocket knife slicing and dicing my way to happiness. Truck had made me angry.
I cut out the fitting that is broken. Here's a what I found.
That's why my coolant was pouring out the bottom of my engine. The connection to the hoses were intact, but the plastic had failed. Its in a low spot, so as it leaks ALL
the coolant will come out.
Going to Lowes tomorrow to make a pipe fitting that will handle the problem from now on. I'm not doing a plastic replacement. Gonna be metal pipe pieces. Permanent.
