Nothing to tighten - the 996 uses a self-adjusting tensionor pulley.

You can try belt dressing - but I would remove the belt and make sure all of the pulleys are okay.

belt dressing wont damage anything right?

Sorry the belt tightening comment won't help! The wife's Infiniti had the same problem with a squealing belt. The dealer said that it was due to a "cheap" belt being installed instead of OEM. Belt dressing only fixed it for a day. Tightening the belt fixed the problem for that car. The belt dressing I used was similar to electrical contact cleaner. It won't hurt anything but might make your engine a little messy.

Thank you...

Ultramens:

This question about belt dressing has come up here recently (last 2 weeks?).

A couple of experienced posters recommended against using belt dressing.

I have used it on my Toyota Pickup and other older cars' fan belts with no problems, but it may be a different story on serpentine belts.

Do a search here and you should find the thread.

Regards, Maurice.

Do NOT use belt dressing on a serpentine belt. It states so on the spray cans. V belts sit IN the V of the pulley, so the dressing can help them seat properly. Serps seat against both the front and back of the belt and dressing actually makes them slip more. I have unfortunately proven this fact on a different car, and could not clean the old serp belt, which was only about 2 years old, enough to make it work properly again and had to buy another belt. All quiet again. I had been using Dayco belts, which cost a bit more, but just went to a standard grooved serp and it is quieter than it was with the Dayco. If you have a "performance" belt, that has a different pattern than just the grooves that match the crank pulley, then that is probably the source of the noise.

Do not use any belt dressing on a serpentine belt. Belt dressing is for V belts only. good luck,

I never recommend belt dressing on any type. It make a huge mess and is a short term fix at best. My opinion is that if the belt is making a noise, find out why. Don't try to fix it with "backyard mechanic in a can".
