Serpentine Belt Function and Importance
The serpentine belt in a 2002 Ford Taurus drives essential components like the alternator, power steering pump, air conditioning compressor, and water pump. Replacing it requires precise routing to avoid engine damage.
Interpreting the 2002 Ford Taurus Diagram
Ford uses a standardized diagram for this model, indicating a counter-clockwise path. Key routing points include:
- From crankshaft pulley to tensioner pulley.
- To alternator pulley then power steering pump.
- Final routing to air conditioning compressor and back to crankshaft. Refer to underhood decal for exact layout.
Installation Steps
Follow these steps for safe replacement:
- Step 1: Release tension using the tensioner pulley tool (typically a wrench).
- Step 2: Remove the old belt, noting any wear or cracks.
- Step 3: Route the new belt according to the diagram, ensuring no twists.
- Step 4: Engage tensioner to apply proper slack, confirmed with deflection test.
Common Issues and Maintenance
Inspect every 60,000 miles or annually for cracks and fraying. Symptoms of failure include squealing noises or overheating. Avoid common errors like incorrect tension to prevent slippage.
Safety Precautions
Work with engine off and cool. Always verify routing against decal. Improper installation risks accessory failure or engine overheating. Use gloves and eye protection during handling.
