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.
A factory Toyota radiator comes with a new radiator cap and the foam in the correct location.

That's right. If you do the job yourself, once you get the old rad out, set it on the ground above or below the new radiator. You want to make sure those hard lines are pointing in the same directions on the new rad as on the old, and you can clock them as described by jht3.
Also, you can take your new rad to a rad shop and have them pressure test it for usually about $25 prior to install. It's worth it, considering the labor involved.

Does that tape replace the foam, like thick weather stripping?

So a quick update on my blown out radiator.

I hooked up the radiator and it looks like there is oil skim floating on top as the water is circulating from the engine. The extra pressure from compression must have made the radiator blow out (although it was looking pretty bad anyway).

So, I guess I need to bite the bullet and do a head gasket. My LX 450 is just shy of 200k.

I bought all new hoses, belts, brackets for the A/C condenser and the rubber grommet with stud attached that secures the radiator to the front. It is good thing I purchased the belts because they were cracking. Water pump was a bit too pricy for me right now at $225+ from the dealer so I'm holding off on that.
