I Need Help Diagnosing A Steering Issue I'm Having

I just finished installing a new aluminum radiator in my 72 demon. While removing the old radiator I accidentally broke a transmission cooler line. While replacing the new radiator and new transmission cooler lines I removed the power steering pump to give me more room to work the new cooler lines through to the transmission.

I finally got everything back together yesterday (it was a process because I went to a V8 radiator on a slant six engine so when I swap over to a 340 I don't then have to replace my radiator). I filled all the fluids and took it around the block for a quick drive.

I now have a situation with my steering. First I noticed a chirping sound when I make a turn, doesn't matter if it's left or right. And then on the final couple turns to get the car back home the power steering would cut out for a few seconds. I checked PS fluid level and that was fine. I am thinking that my belt is slipping either because I got some "gunk" on the belt or there is not enough tension. Is there a process for making sure there is appropriate tension on that belt? Is there anything else I should be looking at?
