Squealing & Burning Smell - Updated!
I've got an '06 NA Foz w/ 142,000mi.
A couple months back, a squealing/whining noise developed from the engine bay. It's only audible at idle, and is especially audible at idle on a cold start. My thought was that this is likely one of the pulleys on the accessory belt, but I haven't done much investigation.
Now just in the last couple weeks, a strong burning smell also developed. I checked and I haven't been losing any fluids, so I don't think I have a significant leak somewhere. I thought I might have accumulated spilled oil and ATF (just did a drain and fill a couple weeks back and I hate the placement of that dipstick), and/or misc. crud that could have reached a breaking point and could be causing the burning smell, so I pulled the battery, covered the alternator and distributor, and sprayed the whole engine bay in degreaser and rinsed it down well. No change to the burning smell.
We did the timing belt kit and water pump a bit over two years ago at about 107k. We replaced the accessory belt at that time, but none of the accessory belt pulleys. Head gaskets were done by a prior owner (unsure when). She burns a bit of oil, but not too bad-- maybe 0.5 qt per 1,500mi depending on season and type of driving.
So, any ideas? Am I totally in left field on the accessory belt idea? How would you diagnose the accessory belt, pull it off and compare? Test individual pulleys by seeing how freely they spin without the belt?
Greatly appreciate any advice.
