Have your front tires high speed balanced
Well, honey, to clear the code on a Cadillac Eldorado 1999 for the service stability system, you'll need a fancy OBD-II scanner. Plug that bad boy in, find the option to clear codes, and let it work its magic. Just remember, clearing the code won't fix the underlying issue causing the stability service light to come on, so you might want to get that checked out too.
your serpentine belt came off probably I just bought a 1996 Eldorado with this same problem. The car won't overheat because there is another belt and tensioner on the other side of the engine for this. Check the belt tensioner the spring probably broke causing the serpentine belt to be loose and fling off.
It sounds like you have a bad water pump. It had seized up on you and has burned the belt.

answer question what can be causing winning noise in my transmission
Thermostat.....
Yes.
If a 2001 Cadillac DHS sometimes won\'t start, becomes idle or just dies it\'s probably a problem with the gear box.
The 1999 Cadillac normal coolant temperature gauge reading should be 180 degrees. A 195 degrees thermostat could be used, causing the temperature gauge to read 195.
I had the same problem on my 94 Eldorado. Almost drove me crazy. I also had my key checked and the ingnition was replaced - no change. On a test drive, I had a fire inside the trunk! It turned out that the pulling motor of the lid had faulty cables that caused the fire. The problem started weeks before the fire, so I imagine there was a short in the wiring causing the anti-theft system to think someone was tampering with the trunk lid and shut down. Remove the plastic cover in that area and have a look at your wiring.
You should take it back to the shop that replaced them and ask. It's possible that something is hung up somewhere that's causing the noise.
the gear on the starter is sliding into the flywheel causing the sound. Just replaced the starter on my 97 Deville. The gear on the old starter would slide back and forth due to a broken spring. The new gear on the new starter if fixed in place. Sounds crazy, but oh so true.
