A squealing noise from the engine belt when started.
Engine oil is leaking on two of the belts, is there a product to seal the leak? on 2000 Nissan Altima
sealers rarely work and are very temporary at best. have a shop find the leak and fix it right.

Stop leak will most likely not stop the leak, and if it is leaking on a belt the fluid will make the belt slip and you will need another belt, you will need to find out where the leak is coming from and fix it.
