Squealing noise from my 92 Dodge Dakota. When I sprayed wd40 on the pulleys the noise went away then I sat it for a little while
I be replaced the serpentine
belt and the idler pulley. I still
hear the squealing after I hit
about 1500Rpms. Could I spray
like wd40 on the pulleys while
reving it to determine which
pulley is squealing?
