i have a brand new drive belt that is squeaking its brains out. The idler pulley, tensioner and pulley alignment has been checked, all ok.
i have sprayed the belt with everything I could think of; WD40, Inox as well as water to isolate the issue to being the belt. I have read the worst thing you can do is spray anything on these belts. In desperation I used soap which worked to quiet the noise at idle with the noise returning above idle. Has anyone used the spray on belt dressings with any success? I would welcome any other suggestions. TIA
