- 10 mm socket
-12 mm socket
-Ratchet
-Breaker Bar (if needed)
- Flat head screwdriver
Instructions:
1. Park your Eclipse on a level surface and turn off the engine. Engage the parking brake.
2. Open the hood and locate the alternator belt. It is the belt that runs between the alternator and the crankshaft pulley.
3. Use the 12 mm socket and ratchet to loosen the upper alternator bracket bolt located on top of the alternator near the front of the car. This will create some slack in the belt.
4. Use the flathead screwdriver to pry the belt tensioner pulley towards the front of the car to relieve more tension on the belt.
5. Use either your fingers or the 10 mm socket and ratchet to remove the belt from the alternator and crankshaft pulleys.
6. Remove the tensioner pulley from the bracket.
7. Inspect the tensioner pulley and replace it if it is damaged.
8. With the tensioner pulley still removed, place the new belt around the crankshaft pulley first, then around the alternator pulley.
9. Install the tensioner pulley onto the bracket, but keep it at its most slack position before tightening the mounting bolt.
10. Use the 12 mm socket and ratchet to tighten the upper alternator bracket bolt fully.
11. Use the flathead screwdriver to pry the belt tensioner pulley towards the front of the car as far as it will go and tighten the tensioner pulley bolt.
- Note: The belt tensioner is spring-loaded and should automatically take up the slack and apply the correct tension to the belt.
12. Double check that the belt is properly seated on all of the pulleys and that is has about 1/2" deflection under moderate pressure from your fingers halfway between the alternator and the crankshaft pulley.
13. Start the engine and let it run for a few minutes. Listen for any unusual noises. If you hear any, turn off the engine and inspect the belt. Make sure that it is properly seated on all of the pulleys and that there is not too much or too little tension.
14. Turn off the engine and close the hood.
