Ford Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Can I get that recording uploaded here?
When the noise occurs do the engine, transmission or brakes act different?
You can upload that file to you tube.
Is there a sound of something you have around the house that I can imagine in my head that your hearing?
Once up to speed and occurring if you shift to neutral, does it still occur?
Any concerns with the tires wearing odd?
I need to run for a while but will return.
I can hear it, kind of a high pitched noise that goes up and down. It for sure sounds like something spinning but it is something that is spinning slow which rules out alot of parts.
Try neutral for me and try changing the blower speeds?
Turn the fan clutch by hand with the engine off to make sure there is some resistance but no noise or wobble.
When out of storage I would drive it till it occurs then stop and remove the belt. Then drive a max of 4 minutes. If the noise is gone then it is for sure going to be something that is spinning and related to the belt. That will help rule out many possible causes or allow you to put more focus on a specific area.
There is only one belt.
Hello again Chris here,
You can remove the belt and start the engine, but only run it a max of 4 minutes or less because the water pump is not spinning, so you do not want to overheat the engine. You could actually take the belt off and make it about 50 miles if driven carefully and you shut it off often. Eventually though the battery would run out of power because the alternator would not be running. This is just a test to see if the noise is from a pulley being spun.
