So today i noticed a consistant whining noise coming from the front passenger side of the engine, i got up real close and thats where it seemed to be coming from. It kinda sounds like its coming from the alternator but it doesnt seem like an alternator issue as i have experienced no electrical abnormalities at all. i dont beleive its the fan clutch as the sound is lessened, or at least inaudible when im driving. it seems its an idle only issue.
Could this be a belt issue? maybe need lube? any input would be good.
Ford is well known for a whiny power steering pump.
If your pulley feels tight, then flush the fluid and add synthetic. I had good luck with that in the past. Now with 150k a ps pump sounds like general maintenance item. Starter went last winter so its due i guess.
i went for a drive just now and the whining came back. when i first started the car it wasnt there. it seems after a drive it comes back, but also, i got up in the bay and found that the whine is definately coming from the top of the engine, near the intake manifold top.
could this be injector noise, or valvetrain noise? its like an electrical or mechanical consistant whine, like something doing alot of revolutions almost....
i found the issue guys, it was none of the above actually. it was so much simpler.
one of the L shaped rubber hoses on top of the intake manifold, the thicker one right below the top of the top radiator hose. the hot radiator hose was resting RIGHT on top of the air line, and thus after 120k miles, it melted the rubber, so much so that it felt like a sheet of rubber paper compared to a normal stiff line. anyway, the soft rubber was getting suctioned together and thus, the whining sound.
