Serpentine Belt Replacement and Diagrams

Not really possible to do on that engine with the current hardware. There is a different accessory drive mount with a different tensioner and idler mount when they didn't have AC. With the location of the idler and tensioner on the AC equipped models, any belt that would fit couldn't be used because there isn't a way to adjust it. You might be able to use an AC bypass adapter but those are more than a used compressor.

What is wrong with the compressor you have? If it's the compressor itself that is bad, but the pulley and bearing are OK disconnect the clutch activation connector and use it as an idler pulley until you can replace it. If the bearing is bad you could just go to a you-pull-it type yard or a salvage yard and get a compressor.

Hello richking12,

# Rotate the drive belt tensioner clockwise and put the drive belt back.(see diagram for location of the tensioner.)

It should follow the diagram provided. Take a look at these diagrams and see if they are the same or different than the one on the car. The belt needs to turn the water pump If it isn't, the engine will overheat. Also, if it isn't connected to the crank pulley, it won't turn.

Let me know.

I don't see how that is possible. Can you upload a pic for me to look at?
