C4 and radiator

[spieser]

I know the connections on the transmission is rear return, but what port in the radiator cooler does this line go to, top or bottom? Stock style radiator.

It's good practice to put the pressure line (front on C4) to the bottom so any air is forced out the top.

it is a closed system where is the air going to go? I would check out someone bronco that came with a factory C-4, but I don't see which way makes a difference.
