I am a Honda tech......use Honda parts! Replace the belt, belt tensioner, water pump, and serpentine belt.
You should also be replacing the spark plugs @ that mi. Have your tech keep a close eye out on #1 through #4 plugs when taking them out. (back 3 cyls. & the one closest to serpentine belt on frt. row). If any of those 4 show any signs of oil fouling your a candidate for piston rings. Honda has an issue with them and has extended your warr.
Your pcm may need a software update as well. My dlr is doing a couple a week.Don't mean to scare ya, just laying down facts.
