What year and engine? I found a video on a 2001 4.0 SOHC, which shows it off the driver side of the engine seemingly under the ignition coils. As such, I can only guess that the coolant line is actually to heat it up so it doesn't freeze. Lots of what comes through there is water after all.

Heated PCV
New-to-me truck ('05 FX4 Off Road) had a thoughtful but not completely efficient P.O.
The PCV was original. I bought one from AutoZone and rolled it into the existing heater pipe.
I was thinking about wrapping the entire thing in insulation but I don't want it to melt.
As it is, I don't want the AZ product to melt either.
And YES, getting the elbow off the PCV itself is the hardest part of the job. The 1/3 turn to unscrew it wasn't difficult at all.
My original one was clogged and barely rattled with severe shaking.
See you in 20,000 mi. or is it 30,000 mi.?
