    I've found all the other pulleys, hoses etc I need, but don't know if Toyota parts site is messing up again, or what, but can't find a number it says is a fit for the tensioner, or the pulley.
    One of these is supposed to be the tensioner assembly number 16620-31012, or
    $91 16620-0W101 Toyota Genuine V Ribbed Belt Tensioner Assembly
    16620-0W101

    I keep getting several numbers for just the pulley 16603-0W030, 16620-0W101

    Hoping it's just the websites messing up again cause, Right now everything keeps saying "fitment not available" even though I'm using VIN to search, or " No Results" for those part numbers.

    Called this morning.
    Toyota says tensioner pulley not a serviceable part.
    Have to buy whole tensioner assembly.
