Stock LS GTO Radiator in 71 Bird, help Does anybody have a hose routing diagram for the stock GTO LS1 radiator? I'm swapping an 04 GTO powertrain in my 71 firebird. I purchased a factory radiator and fan set up in good shape. I'm not sure what all the smaller ports are for. Also, did this have a remote fill or something? There is no radiator fill or cap?
The good news is it fits the core support like a glove.

I have a 2005 GTO radiator and fans, and mine has a filler cap...no idea on that. The pic you have is upside down, but the metal ports on the left side are for trans coolant. Up where the cap SHOULD be, there are two small plastic ports. The higher one vents to the manifold at the throttlebody, and the lower one I ran to an aftermarket overflow.
