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,
