How do you change the serpentine belt on a 2002 Toyota Camry?
All serpentine belts have some kind of tension relief pully or
mechanism. Buy a $20. repair manual. Relieve the tension as
indicated, probably with a ratchet & socket and pull off the
belt. You can draw a diagram before you remove it. To slide the new
belt on you have to release the tension again, then engage. When
putting the belt on it helps to remember that the smooth side of
the belt will meet the smooth pulleys, and the track or ridged belt
side fits into the ridged pulleys.
