What else should I replace while I have the radiator out?

Thank you

 

Water pump, t-stat, all of the hoses.

 

Don't forget the fan clutch.

 

And a new radiator cap.

 

Harmonic balancer comes to mind, to name something not cooling related.
If yours is wobbling, having the radiator out is a good time to use that extra created space to change the HB out.

But where do you want us to stop?
Busted even mentions the radiator cap. Which, indeed, is good to replace, when the cooling system is overhauled....but not key when radiator is out...don't worry if you overlooked it when the radiator was out and back in....the cap can be changed later

 

Just looking for what else could be replaced while it's out that makes sense. No real limit just trying to get a list.

Thank you
