How is the tension set on a serpentine belt?

Depending on the application, your serpentine belt will either have tension placed on it using a movable bracket or an auto tensioner pulley. This pulley uses an internal spring to apply consistent pressure to the belt at all times. If your vehicle does not have a tensioner pulley, the alternator bracket is likely how tension is set on the belt.

Why do I need to check my fan belt?

All of those pulleys need belts to transfer the energy from the crank pulley, and those belts wear out with all of their spinning, heating, cooling, stretching, and shrinking. It’s important to inspect your belts every season to be sure you don’t have any worn, frayed, or stretched belts.

How do you measure the tension on a fan belt?

If you can actually find an ancient tensioner gauge, you would hook it on the midpoint of the longest stretch of belt between two pulleys, and measure how much the belt flexes right there. It sounds complicated, yes, and besides, you don’t have the gauge. There’s another way to gauge the correct tension.
