    noisy serpentine belt on 6.2 mpi-gctid828529

    Hi guys

    I have a relatively new belt on my 6.2 mpi. Its 70 hours old and it ticks like a noisy bug in a forrest!!! it appears the mercruiser label on it is really tacky... it ticks with engine rpm though once hot and been running for a few hours will go away. if i spray the belt with a water disperant spray it goes quiet for a little while. I can feel that the logo part of the belt is really tacky. Has anyone else experienced this? I feel a little odd trying to call warranty on it as its just a noise, though one thats really annoying!!!

    You can use WD-40 or acetone or even lemon juice to remove the label adhesive. If the label itself needs to be removed, be sure to record the numbers on it first.

      Its really etched into the belt, like as if its not supposed to come off. I tried to pick it off with a blade but its really embedded. I was thinking of taking to it with some sand paper so that i dont go through the top layer with the blade... really odd though, the last one was perfect

        Are you sure that it is the label? Sounds more like just a noisy belt.

        Most likely either a belt tensioner needs adjustment or the belt is misaligned.

        Also try some belt dressing (available at most auto parts stores). WD40 should never be used on belts as it is counterproductive. Belts rely on friction and although WD40 can very temporarily reduce the noise, it also reduces the friction and contributes to premature belt wear.

          Serpentine belts are only $25 .....cheap! I suggest you replace it and keep it for a spare in an emergency.

            I had a noisy belt on 6.2 a year ago. It simply needed to be tightened. I will say that the replacement belts for this engine are not cheap. If memory serves, they are north of $80. There are also many belts that seem as if they will fit but wind up being about 1/4'' to short.

              Yes, I agree!

              Plus, you will get very good at changing the belt should the need arise. And, if something happens to your belt on say Friday afternoon on a long holiday weekend, your boating vacation isn't shot because you cant find the appropriate belt. You have your spare readily available!
