Does anyone know of a good "non plastic end tank" radiator for the 5.4L F150 that isn't $600? I've got a leaky end tank that I need to address soon, but I just hate to shell out $185 on another plastic radiator.

 

try one from a F-250

 

I got my new radiator from RadiatorWarehouse, I believe that's the name..Its out of LA..Mine cost about 140.00 if I can remember right..Its for the 4.6 though

 

There are little plastic O-rings on the ends of the rads. what usually happens is that O-ring deteriorates over time from the heating and cooling and it leaks. Any rad shop can pop the end off for you and replace the O-ring for about $50 out the door. If you are brave you could attempt it yourself. I actually have no idea how hard it is to do yourself. It seems pretty straight forward just I have no idea how to do it exactly.
