The serpentine belt on the 2000 Ford Explorer is a single belt that runs all of the drive accessories on the front of the engine. The serpentine belt has ribs on the inside of the belt that run inside of the grooves inside of each pulley. When the serpentine belt starts to develop cracks on the inside of the belt, the belt needs to be replaced before it breaks and leaves you stranded.

Tools Used[edit]

Change Serpentine Belt[edit]

  • Open the hood on the 2000 Ford Explorer and lock it in place.
  • Look for the serpentine belt routing diagram on top of the black plastic shield that covers the top of the radiator. If you do not see the diagram, draw out the routing direction of the old belt with a pen and paper.
  • Look for the tensioner to the serpentine belt on the passenger side of the engine below the alternator. The tensioner keeps the serpentine belt tight around the pulleys. There is a pulley on one end of the tensioner. The pulley has a 3/8-inch square hole in the end of it.
  • Insert the 3/8-inch drive breaker bar into the square hole of the tensioner. Turn the tensioner counterclockwise to loosen the tensioner off of the serpentine belt. Slide the belt off of the tensioner pulley.
  • Remove the belt from the other pulleys. Then remove the belt from the inside of the engine compartment.
  • Wrap the new serpentine belt around the crankshaft pulley first. The crankshaft pulley on the 2000 Ford Explorer is the big pulley on the bottom of the engine.
  • Wrap the new serpentine belt around the remaining pulleys. Be sure to leave the alternator pulley as the last pulley to wrap.
  • Rotate the tensioner counterclockwise again and slide the new belt around the tensioner pulley. Let go of the tensioner and it will pull the slack out of the belt. Look over the belt and ensure that the belt is completely inside of the pulleys.
  • Start the 2000 Ford Explorer and look over the belt again to make sure that it stays seated inside of the pulleys while the engine is running.

Tips & Warnings[edit]

  • The 3/8-breaker bar gives you more leverage to turn the tensioner than a 3/8-inch drive ratchet does.
  • Always wear safety glasses when working inside of the engine compartment.
