Looking for a little help!

Doubt if WD would help your squeak. If you do use it do not get it on the belt.
Is your belt tight ? That is the first thing to check. If it is loose or worn and setting down into the pulley that could cause a squeak. Also the noise could be coming from the alternator bearings. Possibly the water pump, but I would think that it would be leaking coolant if that were the case.
