2000 SAAB 9-3 Repair Question
How do i differentiate a sound that may be a bad "air pump" from another type of noise at startup?
is air pump accessible under open hood? use a listening device lie auto stethoscope to check it out? $5 at harbor freight. or a vac wand us useful for directional sound locating.
why worry about oil screen? if oil pressure is ok it's ok.
Un plug the air pump and see if the noise isn't there
