Inner diameter (abbreviated ID) should be 1.25" - that's my guess based on the fact that nearly all the other hoses are the same size.
Coolant: nothing super special. Prestone 50/50 mix works fine in my car for 10 years now (:

Actual snippet of a conversation from Sept 2013:
Me: Eddie, I can't wait to get the car back when you're done with it.
Eddie: Yeah, you'll be able to give the car gas, and it won't be - like - embarrassing....

I would test the cooling fans before you drive it again. If you lost coolant and the air pocket was centred on the otterstat, it might explain why they weren't on. Not sure why they would run again with the car in accessories. Some of that sounds a bit screwy, but could all be normal. Safest bet would be to ensure the fans come on before getting the engine up to temp.
Jumper the otterstat connections and turn the key to accessories. Both fans should run. Double check both are running and not just one as was suggested.
Test them also without the otterstat jumper but instead while using the A/C. If your freon level is sufficient (only you know that), you should see the fans come on when MAX A/C is selected and the key is turned to accessories. Again, no need to run the engine to do these tests.
It's an easy few minutes to prove they are working prior to getting all your hoses sorted out and coolant refilled and firing the engine back up again. Definitely do all your coolant hose repairs, but test the fans before you drive the car again.

I stopped at O'Reilys and asked them for a 3.5" long x 1.25" ID coolant hose. The guy dug around in the back with a tape measure and found me a hose that would fit and cut it into 3.5" sections for me. I'm going to go swap it out and fill it up with coolant enough that I can drive it out of the garage and wait for a tow back to the house so I can burp cooling system.
