    2002 3.3 belt is a snap to change!

    In case someone wants to change the serpentine belt on these vans, it is very easy to do. It took me about a hour to do but I can probably do it in about 30 minutes now. This is without jacking up the van at all.

    Here are the steps...

    Turn your wheels to the farthest right.
    Crawl under the van (if you're thin like me, you do not need to raise it).

    Remove the plastic splash shield underneath the belt. (1 screw, 3 plastic clippings)

    Locate the tensioner pulley and you will notice a "slot" to the end of it.
    Apply a 19mm wrench into that "slot" and turn counterclockwise. (that's pushing the wrench up if you're underneath)

    This loosen up the slack and you can use your other hand to slip the old belt off. This only took a few minutes to do.

    The hard part is getting the new belt back on since it's tighter and new. Follow diagram on the body and route the belt back on. You should leave the crankshaft pulley last since it doesn't move.

    Now...push on that 19mm wrench on the tensioner pulley all the way up as far as possible. Before doing this, it's best to get a buddy to help you slip the belt back in. Get him setup by sitting next to the right front wheel. By turning the wheel to the farthest right, he should have enough space to reach in and help you slip the belt back to the pulley.

    Good luck.

    Thanks for the info. How many miles does your van have? I am nearing 60,000 and I am considering replacing the belt.

    Glad to hear it went great for you. Let me give everyone a hint. When you pull the old one off, ALWAYS check it next to the new one to make sure it is the same length (not a 1/4 inch or more longer or shorter). It will DRIVE YOU CRAZY trying to put a new belt on that is not exactly the same length as the one you took off. Especially if you are working in an area when you can't really see what you are doing, and are doing it by feel. Remember that the new serpentine belts do not stretch like the old V-Belts do/did. The steel and heavy cord in them is more sturdy then the old belts.
    One other thing is to MAKE SURE that you have a diagram that shows how the belts are routed BEFORE you start. Sometimes, for different reasons, the diagram is missing. If it is missing, BEFORE you remove the old belt, draw your own diagram to help guide you putting the new belt back on.

    Problem is, these belts stretch slightly, so a new one will almost always be a little bit smaller than the old one.

    yep. these belts definately stretch. The old one was about an inch or so longer. Mine had 81,000km on it before I changed it. The old belt looked fine but it was making noises on cold mornings.

    That's the beauty of a modern serpentine belt system, and the spring-loaded tensioner. The slack/stretch inherent in a rubber belt is taken up by the tensioner, making the need for adjustments (as with the old v-belts) a thing of the past.

    A modern Serpentine belt stretching an INCH is pretty much.

    Not really, especially if it's a long one. THe S-belt on my Ford Escort ZX2 is 81 inches long. Stretching an inch is not excessive on a belt that long.

    I only visually compared the two. The old one is definately longer. The belt is quite long so I would agree that stretching an inch or so is normal wear and tear. Afterall, it's only made of rubber.

    The "slot" on the back of the tensioner has disappeared on the Mopar replacement part. Now I have to get a special tool (some have mentioned I can borrow one from some Advance Auto parts store) to put the belt back on. Seriously, how much money did Dayco (or whoever) save by eliminating the back slot?
