if i understood correctly, there is a belt on the driver side that is not moving with the engine running.... is that correct??

the belt that is on the driver side is the AC belt, try reaching for it, and see if it is tight..... if it is loose, then inspect the belt (if it has a lot of cracks on the groves side, then replace it, it shouldnt cost more than 15 bucks) , AC pulley, and the idler pulley (make sure they turn), then tighten the bolt (yellow arrow from the bottom)

if you would rather take the car to a garage, or found a problem that you cannot fix (AC belt is not moving), then you should remove the belt before you drive the car anywhere, if the AC belt stays there, it might get cut and damage other belts (or maybe worst), this is how to remove the AC belt





the tools neede, 12mm socket, 14mm socket (both 3/8" drive), and the same number wrenches...

note: mark down (by a pen or a light scratch) the current position of the power steering bolt, and the position of the AC pully prior to loosening...

1) remove the negative terminal from the battery2) now you have to remove the power steering belt to get to the AC belt, for the Power Steering belt, loosin the bolt (blue arrow in the front), then loosen the belt (blue arrow from from the bottom, although i remember loosening the bolt from the passanger side, that bolt is called the adjustment bolt)3) the Power steering bracket should be loose now, push the power steering pump down (you are better off using a rubber malet)4) the power steering belt (which is the green arrows) is now loose, remove it out of the way5) the AC belt (red arrows) is now easily removed by loosening the idler pully (yellow arrows)6) loosen the pullys bolt (yellow arrow from the front), then loosen the adjustment bolt (yellow arrow from the bottom)7) keep loosening the adjustment bolt untill the belt is loose enough to be removed 8) install back the Power Steering belt, and tighten it's belt untill you get to the mark that you made at the begining of the procedure..

now it is safe to run the engine, drive the car, keep in mind that you wont have a working AC, so dont turn the AC button on untill you install the belt back.....

you can inspect the belt and pulleys, if one of them (AC pulley or the idler pully) is jamed or loose, then the problem is diagnosed. replacing the idler is very easy, but the AC pulley is a real pain in the ars

i hope this helps, good luck

You mention how to remove and adjust the AC and PS belts, how many other belts are there, and do you have any instruction or pictures for tightening them?

In the picture, I don't see the fan, is it removed?

I am getting a squealing noise, and I'm not sure which belt it's coming from as of right now. It's about 10 degrees outside, so I just want to have adequate information so I don't get stuck outside, and get nothing accomplished.

Thanks very much for all the help!

To actually replace all the belts, what do you have to remove?

I just took all of the air ducts off and everything, and still couldn't get much doen to adjust/tighten the belts.

Do you have to remove the fan?

The top radiator hose to get the fan out?

Great instructions when it's open, I just want to know what you have to remove before getting to that point!

Thanks!

fan has to be removed, air ducts also, and then it should be easy to replace the belts

it takes about an hour of constant work to get all the belts replaced, and another half an hour or so to tension them correctly, once tensioned, they might loosen up a little over a couple of days, so tensioning might be needed again (to know, you will hear the belts squeal on start-up)

i suggest replacing all belts with original nissan, they are one of the few things that dont cost much from the stealer....

oh and for the alternator belt, you will find the adjusting and tightening screws on the bottom side (you will see a slot that has a bolt attached in, make sure you loosen that first), and on the bottom left of the alternator if you are looking at it from the front of the car (that screw will loosen the belt when loosened)
