belt noise

I have an 89 ford f150, straight six, auto tensioner for the serpentine belt.... which is makin a ton of noise.
So like any auto-ignorant person, I spray a crapload of belt dressing on it.... This will stop the noise for a minute or two....
than it starts up worse. Not really certain where to go next with it.... Belts in good condition and as such, I don't beleive it is the actual problem.

any advice would help,
Thanks in advance.

Replace the belt. Probably dried out.

Belt dressing is useless. I never use it on anything I own. Pitch the belt and if the tensioner is questionable, that too.

Usually the belt is the problem. Some tensioners have wear indicators that show when they need replacement.

I have had bearing inside the pulley on the tensioner go bad and make a lot of noise, some part places carrier the pulley separate.
On my 94 ford ranger price difference of:
Pulley only $19
Tensioner and pulley $50
If the tensioner arm works smoothy, I would just replace the pulley.

Good luck
