so i was on a road trip and while on the highway my battery light came on and i noticed a difference in my power steering. i pulled over to check it out and both belts for the alternator and powersteering had fallen off the "pully" that links the 2. i noticed that it was just loose so i got the belts back on and tightend it back up but now if i start the car the belts dont move but the bult itself just re-unthreads to make the pully loose again..... i need help on this one!
