I'd have gone with Marvel Mystery Oil. I prefer the smell of that to PB Blaster. And it reminds me of my childhood, when I would use MMO to lubricate my slot carsI pulled on it for a while until it slid off... I cleaned the fan and sprayed PB Blaster into the motor and let it sit upside down and drain out. After letting everything sit in the sun for an hour, I reassembled everything and the fan noise is gone.
On the plus side, my truck now smells like PB Blaster, no need for an air freshener!
