For the 1999 Toyota Corolla with the 1.8L (7A-FE) engine, the serpentine belt routing follows this path:
- Crankshaft Pulley (largest bottom pulley)
- Water Pump Pulley (center-right)
- Automatic Tensioner Pulley (spring-loaded idler)
- Power Steering Pump Pulley (top-left)
- Air Conditioning Compressor Pulley (center-left)
- Alternator Pulley (top-right)
- Returns to Crankshaft Pulley
Important Notes:
- The 1.6L (4A-FE) engine uses separate V-belts instead of a serpentine belt.
- Always route the belt with the ribbed side contacting grooved pulleys.
- Confirm your engine type by checking the vehicle identification plate.
- Release tensioner by rotating clockwise with a 14mm wrench when replacing.
Replacement Tips
Install the belt by securing it over fixed pulleys last, routing it around the tensioner pulley as the final step. Ensure proper seating in all grooves before releasing the tensioner.
