wtf now.. Engine noise

Postby Midshift - August 12th, 2016, 9:48 am

So yesterday morning when I went out to my car to leave for work, it was making an abnormal rattle-rumble. It was roughly 0545 (I work at 0630) so I really didnt have much time to investigate.

This morning I pop my hood and the noise is coming from the left side of the Duratec. So now I get to play super-fun Ear game, " Try to diagnose that noise"..

I'm sure its on the beltline somewhere and/but I hope its not my Waterpump,A/C Clutch or my Power steering.

If this noise keeps up, looks like I'm gonna be taking her in to the Doc (mechanic) ..


A/C has suffered alot this summer, even after a recharge, so maybe it is the A/C Clutch.. :wall: :wall: :wall:

Edit: The noise doesn't seem to stop when I turn off the A/C, so that might not be it.. fuq

any other symptoms other than noise? dimming lights, loss of engine power, rough idle, leaking fluids?

I have not noticed any fluids or an abnormal idle.

Have had a door ajar issue but thats most likely completely irrelevant.

I had a serpentine belt stretch, and the rattling was from the tensioner running out of room to take up the slack. It was at the end of its travel so it beat against the end of its rotation ability and made a hell of a noise.

Escapes/Mariners have timing chains and not belts, so I doubt that's the problem

Hmmmm.
Mine has a serpentine belt. (more commonly referred to as a Fan belt).

I would think though, if the belt was stretched enough to make a loud noise, you'd have weak or flickering lights,
lousy steering, bad AC, etc.

My guess would be a bad bearing on something.
Time for probing with a metal stick to find the culprit.

Whatever it is, I pray it's not too expensive

Sounds like the serpentine belt tensioner bearing. Not PS or AC. Though, I wouldn't rule out the Clutch, but when my AC clutch went bad (on a different vehicle) it rattled more and did stop/start the noise if the AC was on/off.

If you can, hit up Harbor Freight and get one of these:

It will help narrow down the location/cause. :thumb:

Comments about Pittsburgh Automotive Mechanic's Stethoscope:
used to isolate noise in accessory drive belt idler pully. works great
