Pulsar - whirring/screeching noise


Recommended Posts

Hi guys,

I have a 2006 N16 Nissan Pulsar 1.8L manual hatchback (QG18DE engine) with 188000kms on it.

I'm getting this whirring, screeching noise in every gear at around 1800rpm. It started after a 5 hour drive and I noticed it when letting off the gas. The attached sound clip is in reverse, holding revs around 1800 and letting the clutch just bite. It seems to be mainly when reversing or decelerating and don't think I can hear it when clutch is pressed or in neutral. I noticed belts were a tad loose and have tightened them both up to spec (they're only a few months old). I changed engine oil and gear oil recently too. Any ideas would be appreciated.

Cheers, Jack

Hi Jack.....welcome to the Club

I would start with looking at replacing the drivebelts with genuine Nissan belts as there are so many belts in the market that don't have the friction (even when tightened fully) and give noises like this on overrun.
