I need the belt diagram for 94 dodgegrand caravan 3.3

Tensioner badly adjusted or pulleys are misaligned.

Take it back to the shop and ask them to fix the tension under the repair warranty.

There should be enough tension that the belt can't jump the pulleys. There is a small chance is is misrouted.

Google it

There are pictures or diagrams on the internet

Next time make a diagram-- before you remove any belt

Should be a diagram under the hood on most vehicles

If it changes pitch when turning the steering wheel, check the power steering fluid level , if full , may need to be changed.

Check under the hood, most vehicles place a sticker of the diagram on the flat metal piece that holds the radiator in.

There should be a sticker in the engine compartment or in the owner's manual but if not, check with any auto parts store and they can look it up for you. Please rate this answer, thanks.

Get the replacement belt, and then note the pulleys that have smooth finish, and note the pulleys that have the grooved finish.

Just 'thread' the serpentine belt, one pulley after another alternating between the smooth and grooved until the last remaining pulley is the tensioner pulley.

Use the breaker bar to allow the pulley to accept the belt, and you're done.

that's not possible all of those vehicles came stock with power steering so all belt dimensions are taking the power steering pump into consideration,the only one that would change would be the A/C belt depending on whether or not your vehicle came with it or not,a used power steering pump should only cost just a little bit more then a new serpentine belt,hope this helps and good luck

Get your charging system checked out. Your alternator may not keeping up, or your battery may be failing. To get a good answer, get it checked out.
