What Is a Serpentine Belt?
The serpentine belt, also known as a multi-vee or multi-rib belt, is a single, continuous belt
that drives multiple peripheral devices in your car's engine. Unlike older vehicles that
used separate belts for each accessory, modern engines typically rely on a serpentine belt
for efficiency and simplicity. Key functions of the serpentine belt include: - Powering the
alternator (charges the battery) - Driving the power steering pump - Operating the air
conditioning compressor - Running the water pump (in some models) - Assisting other
accessories as needed ---
Understanding the 2001 Ford Focus ZX3 Serpentine Belt Routing
Importance of the Correct Belt Routing
The belt routing diagram indicates how the serpentine belt should be routed around
pulleys to ensure proper operation. Incorrect routing can lead to belt slip, damage, or
failure, which might cause accessory malfunction or engine overheating.
Common Components Involved
- Crankshaft pulley - Alternator pulley - Power steering pulley - A/C compressor pulley -
Idler pulleys - Tensioner pulley ---
2001 Ford Focus ZX3 Serpentine Belt Diagram
While factory diagrams are most accurate, a typical routing for the 2001 Ford Focus ZX3 is
as follows: 1. The belt begins at the crankshaft pulley (bottom center of the engine). 2. It
runs upward to the idler pulley. 3. From the idler, it proceeds to the tensioner pulley. 4.
Then it wraps around the alternator pulley. 5. The belt then moves to the A/C compressor
pulley. 6. It continues to the power steering pulley. 7. Finally, it returns to the crankshaft
pulley, completing the loop. Visual representation (simplified): ``` Crankshaft Pulley -->

Idler Pulley --> Tensioner Pulley --> Alternator Pulley --> A/C Compressor --> Power
Steering Pulley --> Crankshaft Pulley ``` (Note: For actual installation, refer to a detailed
diagram or service manual to ensure precise pulley positioning.) ---
