    Serpentine Belt - When to Change and Preferred Belt

    Hi -

    Just wondering when the serpentine belt should be changed and if there is a preferred manufacturer of the belts.

    I searched for "Serpentine" but couldn't find the answer.

    Thanks all!

    Motorcraft: JK6932AA
    Goodyear: 4060922

    There may be more from Gates and other manufacturers.

    Call 1-800-FORD-788 and press "1". Have the last 6 of your VIN handy. You will get the numbers for FREE. You'll pay $$$ for the certificate.

    MM traded in 8/9/13 @ 128909 miles. It was fun for almost 8 years. I met airmercpun on 1/17/14. He was the new owner of my former ride. -Now gone.

    Update: back in the game with a late build 03 GMGS with some MM add ons like Escape audiophile radio w/Sirius sat radio, rear sway bar, catback exhaust, and header panel.

    See my garage file for part numbers and whatnot.

    IMHO, this site- the members that I chat with- and the ones that I now Hang with- are like my 2nd family. There is such an ongoing welcome feeling here that even members who don't or no longer own the MM can feel.

    Unlike the V-belts of old, serpentine belts don't have a set replacement interval. It's a good idea to check them every 30,000 miles. A few small cracks are normal and do not indicate replacement is needed. If a crack goes across multiple ribs, or the belt has chunks missing, replace it.

    I prefer Dayco PolyCog belts, but the Goodyear Gatorback is a good choice, too.

    Take the belt off and look at the under side. Bend it in half, if you see lotsa small cracks, missing teeth(?) etc, you need a new belt.

    HINT: Keep the old belt in the trunk for emergencies.

    Belts:
    Serpentine (NAPA) – PBH4060923 - stock
    Gatorback (Goodyear) – 4060922 - stock

    I change ours about every 30K. I suppose if your car has less than 30K and you are on the original you should check it for dry rot and replace if necessary.

    Goodyear Gatorback solved my squeel at startup and the 1-2 shift. Going strong for the last 20k miles.

    Had my belt replaced at 100 K even though it wasn't very worn or cracked. Mt mechanic replaced at 148 K when a chirping noise developed. He advised the belt was a factory defect and replaced for free. Chirpping went away. Don't know the brand name. Personally I like all original Motorcraft.

    You know when it breaks it's going to be dark, cold and raining and you won't be able to pull over safely.

    It'll be that one time that you take it out in the rain because your buds want you to get pizza and beer.
