Tools You'll Need:
* Socket set: Various sizes, including metric. You'll need both standard and deep sockets.
* Wrench set: Metric, including both open-end and box-end wrenches.
* Ratchet: A good quality ratchet will make the job significantly easier. A breaker bar might be helpful for stubborn bolts.
* Extension bars: To reach hard-to-access bolts.
* Universal joint: Essential for reaching those awkward angles.
* Alternator wrench: A special wrench designed to grip the alternator's pulley nut is highly recommended. A regular wrench might round off the bolt.
* Jack and jack stands: Safety first! Securely support the vehicle.
* Wheel chocks: To prevent the car from rolling.
* New alternator: Obviously! Ensure it's the correct one for your specific CRX model.
* Gloves and safety glasses: Always protect yourself.
* Shop rags: To clean up any spills or debris.
* Penetrating oil (like PB Blaster): Apply this liberally to bolts beforehand to aid removal.
Procedure:
1. Disconnect the Battery: Always disconnect the negative (-) battery terminal first to prevent accidental shorts.
2. Access the Alternator: This is the trickiest part. You'll need to work mostly from above and possibly below depending on your comfort level and access. You may need to remove some under-hood components for better access; this usually means removing the air intake system. However, the goal is to avoid removing the axle.
3. Disconnect Electrical Connections: Carefully unplug the alternator's electrical connector(s). Take note of how they are connected for reassembly.
4. Loosen the Belt: The belt tensioner on the CRX is usually spring-loaded and requires loosening to remove the alternator. Consult your repair manual for the exact procedure; often a socket or wrench is used on the tensioner pulley to relieve pressure on the belt.
5. Remove the Alternator Mounting Bolts: The alternator is usually held in place by two or three bolts. These will likely be tough to reach. Use your extensions, universal joint, and patience. Penetrating oil is your friend here.
6. Remove the Alternator: With the bolts removed and the belt off, carefully maneuver the alternator out of its position. It's tight, so be prepared for some wiggling and maneuvering. You may need to slightly rotate the alternator or tilt it to clear obstructions.
7. Install the New Alternator: Reverse the process, making sure the belts are routed correctly and tensioned properly.
8. Reconnect Electrical Connections: Reconnect the alternator's wiring harness.
9. Reconnect the Battery: Reconnect the battery's negative (-) terminal.
10. Test the System: Start the engine and check the alternator output using a multimeter (if you have one) to ensure it's charging the battery correctly. Listen for any unusual noises.
Important Considerations:
* Repair Manual: A Honda CRX repair manual is invaluable. It will provide detailed diagrams and instructions specific to your car's model.
* Patience and Perseverance: This is not an easy job in a CRX. Be prepared for it to take several hours, especially your first time. Don't rush.
* Broken Bolts: If you strip a bolt head, you might need to use bolt extractors or other specialized tools. This can complicate the process significantly.
* Accessibility: Some people find it easier to work from underneath the car to access the alternator bolts. Use jack stands if you do this.
If you're not comfortable with this repair, it's best to take it to a qualified mechanic. The risk of damaging other components is substantial, and a professional has the experience and tools to do the job safely and efficiently.
