Yep, I would be worried about that fitting leaking if coolant got to that area. Here's a Denso rad

There is no usual for radiator failure. I've heard of milkshakes before 100K and no problems with 300K so..?? It's a gamble everyone plays. For as cheap and easy to replace as they are I'd replace the rad and upper and lower hoses every 100K just as maintenance.
I'm sure the Koyo or Denso are equal to OEM if not actual OEM (not sure who made the orig rad's for Toyota)
Yes if the cap is original replace it. As far as coolant, well you'll get lots of arguing about that one. Put in what you want is all I'll say. There's just the one thermo so you're fine with that.
My Koyo did not come with a cap. Got one at the dealer.
I don't see how your waterpump could have affected that seal. It's a separate system within the radiator. Pure coincidence is my guess. This is why so many are paranoid about the milkshake issue. You just never know until it's too late.
I know you said you didn't think the squeal is coming from the belts. But with that ATF all over the front of the engine, I'd be surprised if some didn't get on the accessory drive belts, which would then cause belts to slip and squeal.
I vote for the cheapest one. They are probably all made by the same company anyway...
True. And my belts are wet so that is plausible. The truck is just sitting at home right now. I will give it an underbody wash within the next day or two. The only thing is that I've had the hood open before and have heard it coming from inside the firewall. I have had my head in the bay and it happen and it sounds like its coming from within my vehicle, on the drivers side, but being inside my vehicle, it sounds like its coming from outside, behind my steering column. So, I can only assume its in the dash.
So, I want to get my truck back on the road ASAP. So, I will provide a few radiators and let me know which one, or if I shouldn't go with any of them. (I have heard it takes Discount Auto Parts, Tail Lights, Head Lights, Fog Lights, Radiators, Car Mirrors around 2 weeks to send out the radiator. I just need it quicker than that)
Without being there to hear the noise, it's just a guessing game for any of us to diagnose. I'd suggest taking it to a competent Mechanic, that has experience in diagnosing NVH problems.
After you fix your leak, I'd suggest replacing the accessory drive belts, since being oil soaked will weaken them prematurely, in addition to causing them to slip and squeal. While you have the belts off, I'd clean all of the pulleys with brake clean, to remove any traces of oil.
Go to amazon and buy a Koyo or TYC radiator (pretty sure they're the same thing) and have it shipped 2-day or something. It is only $111 for the rad and these are the ones everyone has the best luck with - I've seen lots of guys on here try the other rads and end up replacing them w/in 6 months.
