Serpentine belt replacement: here’s how to put on a serpentine belt yourself.

Immediately replace serpentine belts that show any signs of fraying, cracking or glazing. Replacing this belt on your vehicle may require specialized removal tools. Consult your repair manual.

Be careful when releasing tension from the belt. Spin the tensioner pulley by hand before installing the new belt. Noisy, loose or overly tight tensioner pulleys require replacement. Also check the water pump for leakage. Double-check the belt and tensioner for correct tightness before starting engine.

Why serpentine belts should be replaced every 30,000-60,000 miles:

The serpentine, or s-belt, has gone far to simplify the operation of under hood pumps and pulleys. This one belt runs every engine driven accessory. Your engine turns the water pump, alternator, a/c compressor and power steering pump via one long belt. Problems arise, though, when this particular belt breaks, so replace your s-belt at regular intervals.

Here’s how to put on a serpentine belt:

Consult your vehicle's repair manual for the s-belt removal procedure. Some belt tensioners are sprung extremely tight and may cause personal injury if removed improperly.

  1. Take a good look at both your repair manual and your belt routing diagram under the hood before beginning.
  2. Locate the self-adjusting tensioner. It is spring loaded, be careful when loosening.
  3. Look at the way the old belt wraps around the pulleys. Take the new belt in hand and practice matching the routing.
  4. Position the wrench or special removal tool on the tensioner. Make sure you have room to remove the tool once the tensioner is released. Release the tension. Beware of spring tension!
  5. Remove the old belt. Check the tensioner pulley for wear. Also check all pumps and idler pulleys to make sure they move freely. Install the new belt. Line-up all belt ribs in the pulley grooves. Be sure that the belt is not twisted. Retighten the tensioner.
