I am not a mechanic and I hate to work on cars, but when the Toyota garage told me they would charge me $125 to change the serpentine belt on my 2002 Toyota Camry 4-cylinder engine, I revolted.I knew I could buy the belt for about $30. This is what it looks like under the hood of a 2002 Toyota Camry 4 cylinder engine. Arrow points to the serpentine belt. Study the belt wrap so you know how it goes.
