Hello and thank you for choosing just answer.
In order to better assist you I need to know what engine type do you have? Displacement?
Thank you for getting back to me.
The harmonic balancer bolt is right handed normal bolt but it's super tight and you will need a crank pulley holder to hold the pulley while you loosen the bolt or you could use an air impact wrench to take it off.
You will need a puller, any 2 bolt puller will work doesn't have to be a fancy puller.
You will need a special tool for the tensioner, The tool will be similar to this one.
You will push the tensioner pulley against the water pump pulley to push the tensioner in and then put the pin through the tensioner and when you get your new belt on you simply take the pin out and it will put tension on the belt again.
