How to Change an Accord Alternator Belt
The Honda Accord comes with a single belt known as a serpentine belt that operates the power steering, water pump, air conditioner and the alternator. The serpentine belt is kept at the proper tension by an automatic adjustment tensioner. When the motor is running, the crankshaft turns the serpentine belt around the accessories. As the serpentine belt is turning, the automatic adjustment tensioner keeps the belt at the proper tension. If the serpentine belt becomes damaged, it will have to be removed and replaced.

Tips & Warnings
If the Honda Accord does not have a serpentine belt routing diagram, use a notepad and a pen to draw out your own diagram. Look at the routing direction of the old belt and drawn the same routing direction on the notepad. Use the diagram when routing the new belt onto the pulleys.
Keep your hands and fingers away from moving pulleys when the engine is running.
