Dry Lube for possible belt chirping on a LT?

I asked my mechanic about a slight chirping noise I've been hearing which stops when I disengage the clutch. He suggested it might be the belt which chirps under load but stops when you pull in the clutch and disengage the load. Sounds plausible I guess. He said to spray some dry lube on the pulleys and see what happens.

Presume something like this? https://www.supercheapauto.com.au/p/...d=SCA01080409#

Don't spray crap on the pulley. Find a [different] mechanic who knows how to align the belt.

I'm sure he does know how. It was more of a troubleshooting exercise. i.e. if the chirping stops we know what is causing it.

But yeah that stuff I linked might not be a good idea as it might be tacky not dry. Anything tacky would attract grit and cause problems.

Putting any kind of treatment on the belt or pulley, not specified by the manufacturer, is a momentary fix at best and possibly damaging or dangerous at worst. With the right tools, aligning the belt is a 15 minute exercise so I'd go there first; if you're mechanically inclined, you can do it yourself. The TBird is [in]famous for the chirping belt, although I've only ever had to realign mine once in the last 6 years between tire changes.

If you’re simply trying to troubleshoot.. you can use a small amount of food grade silicone spray. If the chirping stops.. it’s likely your belt. This is solely for troubleshooting.. and not meant to be a fix. Have your belt adjusted.

Yep that's the idea. By coincidence I was in the garage and saw a can of silicone spray and the lightbulb in my head flashed. Spray some on my finger and nothing sticks to it so I reckon it's good to try.

Another temporary troubleshooting technique is rubbing (not your wife's favorite) bar soap on the edge that looks closest to the pulley. Won't last long, but you'll quickly find out that that's where the squeak comes from.

The ride might be fun, but at the end, it really is the Destination that counts.

Silicone lubricant spray has some acetone in it. Don't use that, as in time it may deteriorate the belt ! I tried it till i heard that, then i switched to food grade silicone spray. That is ok on the belt but lasts such a short time it's not worth the effort. The other stuff lasted but i imagine thats because the acetone allowed the silicone to embed into the belt. Not a good thing exceot for noise relief. Try wax, it lasts much longer. There are waxes you can get that are for lubrication purposes which should be good Several people have mentioned using that. I just used candle wax and it lasted a lot longer then silicone and is safe.

I'd be worried that wax would get grit stuck to it & degrade the belt. When I get around to it I'll try some silicone spray.
