What is the routing on a serpentine belt for a 2000 Pontiac sunfire?

Questions about belts are probably the most asked in this forum, along with questions about fuel filters/pumps and thermostats.

If you peruse the answered questions, you'll find a dozen or more involving belts!

Here's the consensus;

Look around under the hood for a factory sticker which shows the routing. If it's still there,

good. It's a great reference.

If the belt is still on the car, make a sketch of the routing before

changing it.

If the belt has broken and you have no sticker showing the routing, you're hosed! Your car will never run again.

Well, not really, but it complicates matters. Some folks, including me, have found diagrams online, but it seems that the belt routing varies from year to year and is dependent on which engine you have. You can't necessarily trust the diagrams you find hither and yon.

The Haynes manual is invaluable, but lets us down on belt routing. There is no singular good diagram.

If you have a broken belt and no diagram, you have a compounded problem. You need to find the correct replacement AND the proper routing.

You could try dropping in to your local dealership and asking them for a part number. That will (probably) get you the right belt. They might be able to get you a routing diagram too.

If you have the remnants of the old belt, it might have a number printed on it which a parts house can translate to a replacement. Or, they might be able to measure it and compare it to what's in their computer.

I've learned a few lessons about belts. If you still have one on the car, but no routing sticker, make a sketch NOW and keep it in the glove box.

If you can see a number on the belt that's currently on the car, write it down and keep it in the glove box.

If you're buying a new, but unknown belt, be prepared. Know the year of your car, the size of the engine and if you have AC or not. This is what the parts counter guy will need to know to hopefully find you the right belt.

While you're in the parts house, buy a Haynes or Chilton manual for your car. You'll need to check out the procedure for changing your belt.

Hope this helps. If you still have problems, come back and drop us a line. We'll try again.
