How to Replace the Serpentine Belt on a 2001 Ford Focus
- 1). Set the socket wrench in to the square hole in the tensioner pulley. The tensioner pulley is the 5- to 10-inch diameter pulley in the upper center section of the belt pathway.
- 2). Remove the tension from the belt by applying downward pressure to the wrench. Remove the belt.
- 3). Install the new belt, following the diagram posted in the engine compartment of the car next to the hood latch. Put the belt on the pulley last, once again using the socket wrench as a lever to lower the pulley.
