I am new here and was wondering what other things besides the water pump and tensioner should be replaced along with the timing belt? TIA

 

I've not done my Pacifica. Many Honda's and a Kia or two. For those cars the Gates kit from Rock auto had new idler pulleys for the timing belt too. Looking at a Pacifica diagram, all you have are the cams, the crank, the tensioner and the water pump pulley. Seems you are changing all that is reasonable. Additionally , the Gates kit only includes those parts, so I'd have to guess the general consensus is thats all you need. Just an observation. Good luck with it.
