I own a 2006 350z, and my drive belt is shaving against something i have no clue what it is, the belts are not worn or old looking their are still black and they seem to be tight not much play at all and their is shavings mostly towards the top of the belt on the motor, also more shavings in areas the belt is located. need help please, i dont want to replace my belts for them to continue shaving or tearing off

 

Welcome- how many miles are on your '06 Z? When did you last change out the accessory belt on the front of the engine?

 

I got the car like 2 months ago and babied it ever since the previous owner seemed to not take care of it as much as i am, Im at 82.3k and i have no clue whens the last time it was replaced but the belts dont look old and i dont wanna replace my belts and they continue to shave off

Welcome.
Get some pics of both belts, and debris.

 

Most rubber belts do not look old, but since you have no idea when, or even if, it's ever been replaced (s/b done at 60K), there's little doubt you should replace it. Just the fact that its been damaged means you are better off replacing them NOW rather than waiting. As for clues, getting under the car and inspecting it will be the best way to determine what the problem is.

Here's a link to a DIY thread with plenty of pictures:

Blow off the rubber shavings with compressed air. Wear an air filter mask and eye protection when you do this.

Take the belt off, then check the tensioner and the rest of the pulleys for play or if they're locking up. Replace worn or broken parts. Replace the belt (stick with OEM). Do not use any type of belt dressing.

Start the car. Turn on the A/C. When the A/C compressor clutch engages, make sure that you're not getting any hang-ups (excessive engine lugging) or squeaking from the pulley area.

Hopefully, problem will be solved and you've just done a full inspection of the belt drive system, which is never a bad thing on an older car.

 

Thanks.
