For those in the future who are looking for some hints and tips, like I was, but who found few, let me pass along what I learned for your benefit.
First, go ahead and get 2 gallons of Honda coolant at the dealer, it's not expensive, and it matches the fluid likely in the vehicle now...mine was the original factory fluid. It's a blue. You'll use about 1.5 gallons when all is said and done.
While there, purchase a few upper and lower plastic panel clips. These are those plastic rivet-like fasteners that hold the panels to the car and surprisingly, the upper and lower clips are different...the lower clips look shorter. You will break some. Trust me.
The upper radiator access panel comes off in a snap. The lower one, not so much. There are plastic panel clips (seemingly) half way back into the wheel well. A flashlight and patience will be needed here to find these pesky things. Oh and there's a HIDDEN clip right under the middle of the bottom of the radiator, that you can access by bending the bumper cover out of the way (it will spring back).
I've seen You Tube videos of guys changing the radiator on their own. I don't recommend it. There were more than a few times it took 2 of us to maneuver something from the top, while trying to clip or unclip a hose on the bottom.
Bring a friend, save an hour, and a knuckle.
The electrical disconnect was insane. There two fan connections went great but there's a thermocouple (I think...it's a single wire) that gets unclipped on the bottom of the fan shroud, man that was no fun at all. Struggled from the top and the bottom to get that puppy free.
I purchased and uses some plastic, rubber hose clamps to hold back the transmission fluid in those lines and they worked great. Highly recommend clamping off the lines, versus some make-shift plug thing.
Once you have the radiator freed, lifting it clear and keeping all the bits from getting stuck on something was a 4-hand affair. Had to keep pulling up, while tucking wires and parts out of the way. Again, bring a friend here to save time.
Once you have the radiator on the table, swapping everything over was a snap, then it's ready to go back in. Use those 4-hands, again. I hope you purchased a new radiator cap. Install it now so nothing gets dropped down that hole later...an open hole just begs for something to be dropped in there.
While all of that was out of the car I took time to replace the thermostat and the upper and lower hoses (I mean, why not...). The lower bolt on the thermostat housing was a bear to get reinserted...it's working blind (and might make you feel dumb in the process). The electrical clip on the back of the thermostat housing can be removed once it is free, mine has a little slack in it, once I got the cover free.
There will be a good bit of coolant trapped in the upper engine, that comes gushing out once you pull the thermostat. I found no good way to contain it, other than rags on the floor. It will make a mess, that I washed down the driveway, and reset everything before continuing. You do not want anyone under the truck when you pull the thermostat.
The whole job took 2 hours, except for the plastic access panels, which I have not yet reinstalled, in case of leaks and to be able to check for same. Was a nice Saturday morning, with only minimal blood and sanity loss.
Rock Auto had all of the parts I needed, save for the Honda fluids, and all and all it was a good use of a Saturday morning, sitting around waiting for the virus thing to return back to near normal.
Final step for me is to go get some replacement plastic clips for the wiring that runs power to the fans. I broke all 5 of those clips taking them off, and that's not how we roll.
