how do i stop my fan belt squeaking on merc 208 sprinter van?

I have a 98' Dodge Ram. I had the belt replaced, still squeeks. Don't use a bar of soap, 3 in 1 oil, degreaser spray, belt conditioner, or WD-40, it will still squeak because of the build-up on the belt, as well as the pulleys. Take the belt off, clean the pulleys with carb spray, and a wire brush, then replace the belt. Make sure the spray you use is dry before starting the engine (to avoid electrical combustion).

a little brake fluid goes a long way - use a few drops on the belt. the belt becomes glazed over causing squeeks.
