I have a 2000 Chevy Venture LS and I need a diagram for replacing the serpentine belt

It's old question, you might find it out already.
If not, here is pictures and diagrams.
It might be two different routing.
Mine is limo which has two alternators.
try to see which is yours.
(red was mine with two alternators. original is black in diagram)

also you may know how to loosen serpentine by insert and turn 3/8 drive ratchet (just ratchet without any socket) to tensioner pulley if not, here is picture (I use 3/8 ratchet + pipe).
Picture was taken after 2nd alternator removed (around upper hose)

I have a 2001 Chevy venture, and the belt broke. Seems that the A.C. Clutch got stuck and the new belt just squeals very loudly.
Does anyonne know how I can measure how long the belt needs to be while by-passing the A.C.? Thanks

Your best ,to cut the old belt,to remove.

You can use a long handle 1/2" drive ratchet, on the belt tensioner.

The only pic is in the shop manual.

Wear long sleeves and arm protector sleeves on top. the fan housing is sharp and a tight fit. You will be there a couple hours.

Draw a picture before you start, and you won't need a diagram

For the 2000 Chevrolet Tracker:

Most modern vehicles have the Belt Routing Diagrams on the undeside of the Hood. But the sometimes disappear.

I do not know if you have the 1.6L In-Line 4-Cylinder, or the 2.0L DOHC In-Line 4-Cylinder. Nor what Engine Options you have (AC/No AC, etc.).

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!
