1. Gather the Necessary Tools:
- New alternator belt
- Socket set
- Wrench set
- Pliers
- Pry bar
2. Loosen the Belt Tension:
- Locate the alternator tensioner pulley on the front of the engine.
- Use a wrench to loosen the tensioner pulley bolt clockwise. This loosens the belt tension.
3. Remove the Belt:
- Use a pry bar to pry the old alternator belt off the pulleys. Start from the outermost pulley and work your way inward.
4. Prepare the New Belt:
- Place the new alternator belt around the pulleys in reverse order of how you removed the old belt. Start with the innermost pulley and work your way outward.
5. Re-tighten the Belt:
- Once the new belt is in place, re-tighten the tensioner pulley bolt. Turn it counterclockwise until the tensioner is snug against the belt.
6. Check the Belt Alignment:
- Ensure the new alternator belt is properly aligned with the grooves of the pulleys. It should sit evenly in the grooves.
7. Install the Belt Cover:
- If the Toyota Previa 1991 has a belt cover, reattach it to protect the belt.
8. Start the Engine:
- Start the engine and let it run for a few minutes. Listen for any unusual noises. If there are no abnormal sounds, the alternator belt has been successfully replaced.
9. Check the Belt Tension:
- After the engine has run for a few minutes, check the tension of the alternator belt again. If it's too tight, loosen it slightly. If it's too loose, tighten it a bit.
10. Enjoy the Smooth Ride:
- Take your Toyota Previa 1991 for a test drive. The alternator belt is responsible for powering various components, including the alternator, so a properly tensioned belt ensures optimal performance.
