2000 Sephia Timing Belt

Hi everyone I am about to change out the timing belt on a 2000 sephia..the autodata timing belt manual recommends replacing the timing belt tensioner spring. Is this pretty simple I have never done one..Also any need to know info on changing this belt out will be appreciated..

it is actually pretty self explanatory if you are mechanicly encline. remember how you took it off and install it in reverse order. If you need step by step feel free to ask there are no tricks to it

Thanks fastkia, even though I am a mechanic I find it sooooo easy to just ask for advice when I come across an unfamiliar job...I also stop and ask for directions when lost...working smarter not harder..
