A factory Toyota radiator comes with a new radiator cap and the foam in the correct location.if you loosen the nut on the drivers side fitting, you can spin it around like hands on a clock. i trusted that as delivered by TYC, the fitting would be in the correct position. it wasn't, and caused the rubber hose to press against the metal frame of the truck. after replacing all the trans lines "while i was in there" fixing the busted one (NLA as well), a simple loosening and re-tightening got that hose positioned juuust right.
also, go to Home Depot and get some of that sticky weather stripping to better seal the radiator to the core support frame. aids in cooling.
