Attempting to remove the power steering pulley, as you can see from the photo some damage has already been done. Before more is done, can anyone tell me if this is left handed or right handed? Should the radiator come out first? Don't want to strip it down even more. Thank you all in advance.

 

Right handed (you can even see that in your excellent picture).

Looks like someone tried locking pliers ("Vise-Grips") on that. You might consider picking up a 6-pt socket of the correct size. You might need to lightly deburr the nut with a file to get the socket to fit. Don't go for "neatness," you want the socket to fit snugly.

 

thank you scope103

 

I use my 1/2" impact if you don`t have one .

Keep the belt tight and use a 6 point socket.

You might want a new nut I know I would

 

definitely a good point on that nut!! @wyoming9 great suggestion on the impact I do believe we one of them, thank you. We'll be able to tackle it now this weekend.

 

For what it is worth my 1/2" impact will break the nut loose with the pump laying on the bench.

just holding it with my other hand to keep it from sliding away
