Default belt squeal at half throttle

My belts are 7 months old not worn out, I put belt dressing.

It only squels at half throttle, Not partial throttle, not WOT but half.

It wont squel in N or P if I rev the engine.

What can be the problem.

Do you have the AC on when it squeals?

Belts squeal when they slip. Belts slip when they are loose. One cause is a weak tensioner spring. Also could be one of the pulleys is binding due to a bad bearing or mechanical problem in the driven unit. If you see rubber dust around a pulley, that indicates slipping, try that one first to see if it is more difficult to turn than it should be.
