Hello,
My daughter has a 2002 Nissan Pathfinder and apparently by changing out both belts it didn't correct the squeaking problem. She called me this AM and said they sqeaked all the way to school, approx. 5 miles. Any help in this issue would be greatly appreciated, Thanks. Kerry
Hello there, are you sure the belts are the one's squeeking? there are other parts that might produce the same squeeking sound namely: damaged alternator bearing, damaged waterpump bearing/bushing, damaged aircon bearing and damaged idler pulley bearing. try to determine which one by grabing a fairly long water hose, approximately about a meter long just so you could manuever it on the squeeking area during the enging running on idle to isolate the problem. much like a sthethoscope used by doctors. the stronger the sound on that particular area could pin point your problem. just watch out for the fanblades and fanbelt pulleys.
If changing the belts didn't stop the problem, it may be a pulley that is making the squeak, not the belts. When belts age, they tend to form a glaze on the contact surface, which can cause slippage, or squeak, or squeal, also if engine fluids get on the belt due to leaks or spillage, it can cause a problem. If you feel it's definitely the belt(s) making the noise, check the belt tensioner for wear. There is usually an indicator (stamped on the tensioner) that shows if it is in need of replacement. If that's the case, it would not keep the belt(s) tight, and could cause them to slip and squeal. Let me know what you find, or if you have further questions. Curt
I checked further, and apparently this vehicle doesn't have a tensioner, so I would assume it must be adjusted at the component locations (alternator, a/c pump, ps pump, etc). If a garage put the belts on, bring it back and have them check the belts for proper adjustment (tension). If they aren't tight enough, they will squeal. If you, or a friend put the belts on, tighten them up and the squeal should stop.

Buy new replacement belt. Select correct socket and ratchet handle to move automatic belt tensioner to slacken old belt. Slip off old belt, slip on new belt following correct belt path over all pulleys. Re tension belt with auto tensioner. Drive vehicle, job done!
there are YouTube videos, watch them.....
Very often the power steering belt can cause this noise if it is loose or just worn. The pump itself can cause a noise check and make sure it is full of fluid.
i have 96nissan pathfinder and belt squeaking when i start the engine and stop and start squeaking when iam driving and stop and come back it a new belt
It could be either. You can check (2005 pathfinder recalls) and it will state all the recalls on that vehicle. Sometime the belt gets worn and weather cracked which will make it squeak, because there's not a good gripping back going over the pulley's. The pulley's are moving so fast that the belt slips. I would check the belt for cracks and it would be a lot cheaper to go with changing out the belt first. Even though you may not see cracks, they could be there and it could also be stretched. Good Luck
It's most likely a slipping belt. If the belt is heavily glazed, replace it. If it is a serpentine belt, check the spring on the belt tensioner - it should take a significant amount of force to pull it back to release the belt.
Also, check the tensioner pulley, alternator and A/C clutch bearings while you are at it. If there is any roughness or play in the bearings, this could generate noise.
IF ITS MAKING A SQUEAK PUT SOAP ON THE BELT, AND LAY CARDBOARD UNDER VEHICLE OVER NITE AND CHECK FOR LEAKS OR IT MYBE USING IT IF YOU GOT HIGH MILEAGE ON VEHICLE..
it could be the timing belt.
If it is the timing belt, it may sound a little different when cranking it. It may turn over faster, sounding free, or it may sound two toned when cranking (normal, then fast, normal then fast with every revalution)
Hope this helps
