radiator

i have an 02 trans am ws6 the power steering cooler went out so i took it off and replaced it with its own cooler and ran a radiator hose from a trans am the pormblem is that it keeks leaking from the upper neck is the radiator different on ws6 from trans am this is my 2nd hose

It should be the same. I removed our P/S cooler, even though it was not leaking, and replaced the upper hose assembly with a GM hose for a "2002 Camaro". If it is the hose, and not a cracked radiator, you can dry everything off and carefully run a bead of RTV around the neck (not the inside of the hose, as it may then enter your cooling system). After installing the clamp, let it set for an hour or two so the RTV can cure a bit before refilling the system with coolant. On older cars that have pitted aluminum water necks I have done this several times without any issue and haven't had one of them leak yet.
