if the squeking goes away you eighter need a new belt

or

a tensioner

or

a roller ..

goodluck

so i should wd-40 the pulleys and what about the fan it looks and sound like it needs some lube also, what do you think?

no

you should first take the belt off and see which tensioner or pulley is making noise ..

then you replace it or them

get a new belt

install and noise should go away

LUBE will NOT fix your problem

For me to do that would i need a special tool or something of the sorts?

Old belts get a glaze on them. The glaze squeaks. Bearings make a different noise. Spray some water at the belts while its running. If noise reduces or goes away change the belts!
