For a 2004 Ford Escape serpentine belt diagram, the routing depends on your specific engine. Here's a guide for both engines:
Locating Your Engine Size
Check the emissions sticker under the hood. Engine sizes are either:
- 2.0L Zetec I4 (4-cylinder)
- 3.0L Duratec V6 (6-cylinder)
Serpentine Belt Diagrams
1. For the 3.0L V6 Engine
- Crankshaft Pulley (A) - Bottom Center.
- Power Steering Pump (B) - Top Left.
- Idler Pulley (C) - Center Left (between A and B).
- Alternator (D) - Top Right.
- Tensioner Pulley (E) - Bottom Right (spring-loaded).
- Air Conditioning Compressor (F) - Bottom Left.
- Routing Order: Crankshaft (A) → Power Steering Pump (B) → Idler (C) → Alternator (D) → Tensioner (E) → AC Compressor (F) → Back to Crankshaft (A).
2. For the 2.0L I4 Engine
- Crankshaft Pulley (A) - Bottom Center.
- Water Pump (B) - Top Center Left.
- Alternator (C) - Top Right.
- Tensioner Pulley (D) - Center Right (spring-loaded).
- Power Steering Pump (E) - Bottom Left.
- Routing Order: Crankshaft (A) → Water Pump (B) → Alternator (C) → Tensioner (D) → Power Steering Pump (E) → Back to Crankshaft (A).
Replacement Steps
- Safety: Ensure engine is off and cool. Disconnect the negative battery terminal.
- Release Tension: Locate the spring-loaded tensioner pulley. Insert a 1/2" drive breaker bar or serpentine belt tool into its square hole. Rotate firmly clockwise to release belt tension.
- Remove Belt: Slip the old belt off one pulley while maintaining tensioner pressure.
- Install New Belt: Route the new belt precisely using the diagram. Double-check alignment on all pulleys.
- Apply Tension: Slowly release the tensioner, ensuring the belt seats correctly.
Key Tips
- Inspect pulleys for damage or misalignment while the belt is off.
- Check belt tensioner operation: It should move smoothly and provide strong spring resistance.
- Recommended belt length: 82.5 inches (2095mm) for V6, 74.8 inches (1900mm) for I4 (confirm with belt part number).
Always verify routing against an actual diagram label found on certain models or reference your owner's manual. Incorrect routing will cause immediate belt failure.
