Squeaky fans?
when I turn off the car, there is a squeaking noise that continues for a little while from the engine bay that gets slower and slower then stops. Presumably the cooling fans squeezing? Is there an easy fix for this? Little hesitant to just start spraying wd40 down there. Thank you.

Unless your cooling fans have been modified from stock operation, the fans DO NOT continue to run after the cars engine is shut off. While some other automobiles may have cooling fan setups that run after the engine is OFF, the C5 does NOT.
Even if your cooling fans have been modified to run with the engine OFF, I would NOT use a lubricant to try and stop any noises you are hearing. There is a problem that needs to be identified and corrected and spraying WD40 is NOT the solution. JMHO

It probably takes a few seconds for the rotation of the blades to come to a complete stop. If you are hearing noises from the fans then they may have some debris such as a plastic bag in them or may be telling you that the bearings inside the motors are going bad. I still would NOT spray a lubricant on the motors/blades. There is a reason for any noise and that reason needs to be determined and corrected.Your car, spray away if you really think WD40 will be a permanent fix.........

I'd presume that 1 or both bearings are on their way out in the
fan motors.

OR, get a friend to take a ride with you. After you drive around for a while, so the fans are on, and running, stop the car, open the hood, and have the friend shut the car off, while you're observing the fans......

I still have the squeaky fans. When the car is off and I reach down and spin the fan it squeaks like crazy. Looks like you can replace just the fan motors instead of getting the whole assembly. They are about 70 bucks from gm direct.
