    Hey guys, I just got my super nifty mechanic's stethoscope and found out that my high pitched whining noise is coming from one of my pulleys. I'm about to go the store to get the pulley, I just want to make sure I'm getting the right one.

    The noisy pulley is the one directly to the left of the alternator, under the oil filter, small and silver. Is that this pulley?

    This is for my 4.0L V6 Tacoma.

    Also, I'm at 60,000k miles, would it be a good time to replace the belt as well? The belt itself looks fine.

    Thanks!

    To answer your question, from your description, yes it sounds like you have the correct part.

    In order to do this repair, you will be removing the belt, and if i recall, they cost about 20 bucks.. So it would save you some future time if you did it now, but if your belt looks good, no cracks etc then its probably not imperative. I personally would probably do it just because you've already got the belt off.

    This might help you too:

    If it's not the koyo bearing idler pully you might be re-replacing it sooner than expected. I just replaced mine, make sure your belt is seated correctly after install or you'll b replacing that to.

    Perfect thank you. That diagram is exactly what I needed. Thank you for confirming.

    Anything special I should know for install? I've done serpentine belts before, just not pulleys.

    It'll be a pain! Lol
    The pully will be on tight. Have patients loading the belt. It can be frustrating taking tension off and lining everything up at the same time.

    Nope, its really not that hard. Put a breaker bar on the tensioner pulley, pop the belt off. Use that link I put in for the belt routing diagram. To remove the idler pulley, just follow that link I put up again. You can reuse the old shield, thats what I did. I actually purchased the Gates idler pulley/tensioner kit (replaces all of them) for like 175 bucks. The bearings are NTN canada, and have held up great. If you've done serpentine systems before, this is really nothing special. Oh I would recommend taking off the engine cover (2 10mm bolts) to remove that plastic cover. Just gives you some more hand room.

    Like someone else said, make sure the belt is correctly on the pulleys before you go driving. Or you'll be replacing it again!

    Thanks for the help gentleman. I'm off to the parts store. Wish me luck trying to tell them what parts I want in English and them responding to me in Español.
