How Long Does It Take To Replace A Rebuilt Alternator On A Honda Crv?


Replacing a rebuilt alternator on a Honda CR-V typically takes 1-2 hours for an experienced DIY mechanic. The exact time can vary depending on your skill level, the model year of your CR-V, and any complications that may arise during the replacement process.

What Tools Do I Need to Replace the Alternator?

To replace the alternator on your Honda CR-V, you’ll need the following tools:

  • Basic hand tools (wrenches, sockets, ratchets, pliers, etc.)
  • Serpentine belt tool or long pry bar
  • Jack and jack stands (or ramps)
  • Torque wrench
  • Wire brush or sandpaper (for cleaning electrical connections)

Having the right tools on hand will make the job easier and faster.

How Do I Prepare My Honda CRV for the Replacement?

Before starting the alternator replacement, you’ll need to prepare your CR-V:

  1. Park the vehicle on a level surface and engage the parking brake.
  2. Open the hood and locate the battery. Disconnect the negative battery cable first, then the positive cable.
  3. Raise the front of the vehicle using a jack and secure it with jack stands or ramps.
  4. Remove the front wheels and any plastic covers or shields that block access to the alternator.

Proper preparation will ensure your safety and make the alternator more accessible.

What Steps Are Involved in Replacing the Alternator?

Here are the typical steps for replacing the alternator on a Honda CR-V:

  1. Locate the serpentine belt and use a belt tool or pry bar to release the tension on the belt tensioner.
  2. Remove the serpentine belt from the alternator pulley.
  3. Disconnect the electrical connections from the alternator (battery cable, wiring harness, etc.).
  4. Remove the alternator mounting bolts and carefully remove the alternator from the engine bay.
  5. Install the new (rebuilt) alternator in the reverse order, making sure to properly route the serpentine belt and tighten the mounting bolts to the specified torque.
  6. Reconnect the electrical connections and battery cables.

It’s essential to follow the specific instructions for your CR-V model and take your time during the installation process.

How Long Does the Replacement Process Typically Take?

For an experienced DIY mechanic, the entire process of replacing the alternator on a Honda CR-V typically takes 1-2 hours. This includes the preparation, removal of the old alternator, installation of the new (rebuilt) alternator, and any necessary cleanup or adjustments.

However, if you’re new to this type of repair, it may take longer – potentially 2-3 hours or more, depending on your skill level and any complications that may arise.

Are There Any Special Considerations for a Rebuilt Alternator?

When installing a rebuilt alternator, there are a few special considerations:

  • Inspect the alternator for any signs of damage or missing components before installation.
  • Ensure that the rebuilt alternator is compatible with your specific Honda CR-V model and engine.
  • Follow any specific instructions provided by the manufacturer or rebuilder for proper installation and break-in procedures.
  • Be cautious of any potential quality issues with rebuilt alternators, as the quality can vary depending on the rebuilder.

It’s generally recommended to purchase a rebuilt alternator from a reputable supplier or consider a new alternator from the original equipment manufacturer (OEM) for optimal performance and reliability.

What Should I Do After Replacing the Alternator?

After successfully replacing the alternator, there are a few important steps to take:

  1. Reconnect the battery cables (positive cable first, then negative).
  2. Start the engine and check for any warning lights or unusual noises.
  3. Use a multimeter or voltmeter to verify that the alternator is charging the battery correctly (typically around 13.5-14.5 volts).
  4. Reinstall any plastic covers, shields, or wheels that were removed during the replacement process.
  5. Take the vehicle for a short test drive to ensure the alternator is functioning properly under load.

Following these steps will help ensure that the new alternator is working correctly and that your Honda CR-V is ready for safe operation.

How Can I Test the New Alternator to Ensure It’s Working Properly?

To test the new (rebuilt) alternator and ensure it’s working properly, you can follow these steps:

  1. With the engine running, use a multimeter or voltmeter to check the voltage at the battery terminals. The reading should be between 13.5 and 14.5 volts, indicating that the alternator is charging the battery correctly.
  2. Turn on all electrical accessories (headlights, air conditioning, radio, etc.) and check the voltage again. The voltage should remain within the normal range, indicating that the alternator can handle the increased electrical load.
  3. If you have access to a load tester, you can use it to simulate a high electrical load and verify that the alternator can maintain the proper voltage under those conditions.
  4. Check for any warning lights or unusual noises from the alternator or serpentine belt while the engine is running.

If the alternator passes these tests, it’s likely functioning correctly. However, if you notice any issues or abnormal readings, it may be necessary to have the alternator professionally tested or replaced.

What Are Some Common Issues to Watch Out for After Replacement?

Even after successfully replacing the alternator, there are a few common issues to watch out for:

  • Loose or improper belt tension: This can cause noise, premature wear, or even alternator failure.
  • Loose electrical connections: Loose battery cables or wiring harness connections can prevent the alternator from charging properly.
  • Faulty voltage regulator: If the voltage regulator in the rebuilt alternator is defective, it may not charge the battery correctly or could overcharge it.
  • Bearing noise or vibration: Worn bearings in the rebuilt alternator can cause noise or vibration, indicating a potential failure.

If you notice any of these issues, it’s important to address them promptly to prevent further damage or alternator failure.

How Can I Prevent Future Alternator Failures?

To help prevent future alternator failures in your Honda CR-V, consider the following tips:

  • Regularly inspect the serpentine belt for cracks, wear, or proper tension, and replace it as recommended by the manufacturer.
  • Check battery connections and clean any corrosion to ensure proper electrical flow.
  • Have the charging system tested periodically, especially if you notice any warning lights or charging issues.
  • Replace the alternator with a high-quality, OEM or reputable aftermarket unit when necessary.
  • Avoid excessive electrical loads or accessories that may overwork the alternator.
  • Address any underlying issues, such as a failing battery or electrical problems, that could contribute to alternator failure.

By following these preventive measures, you can help extend the life of your Honda CR-V’s alternator and avoid costly repairs or breakdowns.

Wrapping Up

In conclusion, replacing a rebuilt alternator on a Honda CR-V is a relatively straightforward process that can typically be completed in 1-2 hours by an experienced DIY mechanic. However, it’s essential to have the right tools, follow the proper procedures, and take the necessary precautions to ensure a successful installation and prevent future issues.
