Be sure to remove the tensioner before rolling in the new chain. Clean it and reassemble per the FSM after installing the chain or you'll overtension the new chain.

You'll need to remove the thermostat housing to remove and reset the tensioner assembly. Consequently, you will need a thermostat housing gasket (not the o-ring). Now is also a good time to replace the bypass hose ( I think that's what it is called) that comes out of the bottom of the t-stat housing.
