Transmission cooling lines in new aluminum radiator
Captkaos:
if running inline I always run trans to rad cooler, then to rad to external if you can mount it at the front.
GM ran all of them that way when they did HD trans cooler.
I am currently rerunning my Turbo truck remote as there is no room at the front with the Rad, AC and Intercooler. (pics will be posted)
VileZambonie:
Buy yourself them there braided trans cooler lines. You can loop em any which way you need to and they're cheap $$$
JohnnyPopper:
So is the consensus that the severe reduction in volume, i.e. 1/2"ID to 1/4"ID is not a concern?
JohnnyPopper:
I laugh! Amazed that after all these years, with the potent brain trust embodied in this website, that no one will answer the question of volume.
Is it hubris? Many have said that an external cooler is good, mixed with the internal of the radiator, and so on, but no word, answer, opinion, or maybe just a fart, about volume's factor in proper cooling.
Perhaps I'm expected to derive the correct answer from non-direct comments to the question?
Sad.
ehjorten:
Johnny...I will take a stab at it...the factory cooler lines are 5/16" tubing, which means the OD is 5/16". I am not sure what the wall thickness is, but if it is 0.030" then the ID is 0.0253". A standard 5/16" tubing flare nut is a 1/2"-20. 3/8" tubing flare nut is a 5/8"-18.
I would say that you are okay.
