What fan belt brand you guys prefer?

[vectorit]

Silly question here, but I can't seem to get my fan belt to stop squealing on acceleration. It's as tight as one could get it, and probably tighter than it should be. I have even sprayed belt grip on the pulley, and I still get that screech noise when I rev past 3k from a stop.

I am using a Gates model from the local Auto Zone, and it has very little mileage on it.

I'm thinking I need to find a brand that is narrower, so that it sits deeper into the pulley grooves so it can get more of a contact surface?

Any suggestions?
