Ok so i have a whining noise coming from a pulley, i think its about time i change my belt ( which i never did) but knowing the name of these pulleys will help me locate them in the service manual or part #........ thanks

The lower center one is the crankshaft damper pulley. The one to the right in the illustration (left on the car) is the air conditioner compressor pulley.

Please note that changing the damper pulley requires some knowledge of what you are doing. You can ruin the timing chains by turning the crank the wrong way, and you have to replace the front seal.

Sounds like i might be just changing the belt.....

I am not following you. How is this possible? The crank is still connected to the the cams with the pulley removed via the timing chain. The removal of the pulley has nothing to do with the timing/chains on the engine.

Op I bet the whining noise if from the tensioner pulley.

The timing chains tend to follow interesting paths over guides and tensioners. If the crank is turned backwards, they can get stuck on the guides and break or jump off.

Thanks for the explanation. I still don't see how that is possible. Take care.

Possible. I sometimes found the whining noise was the passenger.
