Pulley system
I am getting a horrible grind sound from one of the wheels in the pulley system of my 97 century. If you are looking at the engine it is the wheel or pulley closest to you at the bottom. I believe it is somehow part of the cooling sytem or fans. If the center portion of the wheel is spinning it sounds fine...however, the center portion periodically stops spinning emitting a horrible sound. It seems like I can effect this by changing the blower settings in the cabin.
Is this some sort of clutch on the fan belt?
Does it just need some grease or does it need replacement?
What part is this?
Thanks for reading.
