Seems like a drive belt problem, to confirm pour some water on belts the noise should go away or may get louder for a second. If either happens the belt or belts needs to be adjusted or replaced. Good Luck, If I fixed ya, leave me a FIX-YA comment thanks

Need to check the ground path on the squealing relay. A poor ground will cause this condition.

Its a 2006 nissan sentra 1.8 i want to know when the squealing happens. I was told the pulley and the turpentine and a/c belts must be replaced.


They may very well need be replaced. Can't say for sure because I can't see it. Look at the belts for any cracks. Serpentine belts has a spring loaded tensioner. There may be a limit gauge on the tensioner that would show when the belt is stretched to its recommended limits. Pulley bearings can go bad and make noise. Plastic pulleys do wear out.

My 2006 Sentra has a squeal coming from the front of the motor,the car is not over heating or losing amps belts look good also.sounds like a vacuum leak.


Squealing from engine bay is a pulley bearing or a belt slipping. Idler pulleys go bad and should be changed out the same time as the belt.

The fans in my 1983 nissan sentra just stopped.


It is most likely a pulley that needs oiling or replacement. If fans are ran by a belt, the fan clutch may be stuck or pulley is seized.
If the fans are electric, the motors may have fried or relay is shot.

Chirp when starting


You probably have the same issue as many Sentra owners- bleed off of fuel pressure. This would cause a hard starting condition when the vehicle sits overnight. See TSB# NTB05-052a for the procedure. This is a dealer-only repair (parts are not available aftermarket).

As for the squeal, I've seen a LOT of this- the belts on these vehicles are less than excellent quality. The belts might look fine and some mechanics will say that they don't need to be replaced, but they are noisy and they can't be quieted up even by overtensioning them. Replacement is the only repair. Aftermarket belts can also be very noisy, so I would suggest Original Equipment (Nissan) belts.

Hope this is helpful!!!
