The other day I changed my leaking (rotted out) thermostat housing and while refilling with coolant noticed the top hose (above the a/c compressor) had a cool spot. I decided Ford must have been in a hurry to finish up and came up with the goofy hose that has the high point causing the dead spot (cavitation point?). I made an aluminum center piece to realign and lower the hose after cutting it in the middle as well as turning it around, cool spot is now gone. I am considering adding a fitting to the center piece with a tiny bleed hole back to the bottle via the small hose coming from the radiator top tank.
When I refill them with coolant I usually pump the upper hose to force the air bubbles out until it is full. Then run it up to operating temp to open the thermostat and re-check it and top it off.
