    Glad to hear it is going to be a simple fix

    Received the new water pump and installed it. Noticed my idler pulley has a little play side to side. Rotated smooth and quietly can’t say it spins freely like other idlers I have seen Replacements for this part are surprisingly expensive. Anyone know any diagnostic to tell this part needs a refresh? Can the bearing be replaced?
