changing thermostat

I have noticed this summer my temp gauge is running up a lot higher than normal. I used to never be able to get the gauge to move past the first hash mark on the gauge now it goes to the third hash when pulling hills with the trailer, i used to see the gauge slowly rise to the first hash mark then it would quickly go just behind the first hash mark like the thermostat was opening up. So my best guess is that my thermostat is not opening properly. I just glanced at it tonight to see what it would take to change it. It appeared to me you have to take off the main belt and remove the alternator first is this correct??? also where is the best place to find a thermostat a regular auto parts store or cummins?? and also will i need a new gasket and RTV sealant.

Thanks in advance
