Specifications

Installation / Setup

This T-bolt is designed for direct replacement of an existing battery terminal bolt. Ensure the vehicle's battery is disconnected before beginning any work on the battery terminals.

Safety Precautions:

• Always wear appropriate personal protective equipment, including safety glasses and gloves.
• Ensure the vehicle's ignition is off and the battery is disconnected to prevent electrical shock or short circuits.
• Avoid contact with battery acid.

Installation Steps:

1. Disconnect Battery: Carefully disconnect the negative (-) battery cable first, followed by the positive (+) battery cable.
2. Remove Old T-Bolt: Loosen and remove the old T-bolt from the battery terminal clamp.
3. Clean Terminal: Clean the battery terminal post and the inside of the battery terminal clamp to ensure good electrical contact. Use a battery terminal brush if necessary.
4. Insert New T-Bolt: Insert the Dorman 64740CD T-bolt into the battery terminal clamp. Ensure the T-head is properly seated within the clamp's slot.
5. Secure Clamp: Place the battery terminal clamp onto the appropriate battery post (positive or negative).
6. Tighten Nut: Thread the washer and nut onto the T-bolt. Hand-tighten the nut, then use a wrench to tighten it securely. Do not overtighten, as this can damage the battery terminal or clamp. The connection should be snug and prevent movement.
7. Reconnect Battery: Reconnect the positive (+) battery cable first, then the negative (-) battery cable. Ensure all connections are tight.

Operation

The Dorman 64740CD Battery Terminal T-Bolt functions as a critical fastening component for securing battery terminal clamps to battery posts. Once properly installed and tightened, it maintains a secure electrical connection, allowing the battery to supply power to the vehicle's electrical system.

Maintenance

• Regular Inspection: Periodically inspect the battery terminal connections for corrosion, looseness, or damage.
• Cleaning: If corrosion is present, disconnect the battery and clean the terminals and T-bolt using a wire brush and a baking soda solution. Rinse with water and dry thoroughly before reconnecting.
• Tightness Check: Ensure the T-bolt remains securely tightened. Loose connections can lead to poor electrical contact, starting issues, and potential damage.
• Corrosion Protection: Apply a thin layer of dielectric grease or anti-corrosion spray to the battery terminals and connections after cleaning to help prevent future corrosion.

Troubleshooting

Common Issues and Solutions:

• Loose Connection: If the vehicle experiences intermittent starting issues or flickering lights, check the T-bolt for tightness. A loose connection can cause poor electrical flow. Tighten the nut securely.
• Corrosion: Excessive corrosion on the battery terminals can impede electrical current. Refer to the "Maintenance" section for cleaning instructions.
• Damaged T-Bolt: If the T-bolt or nut is stripped, bent, or otherwise damaged, it should be replaced immediately to ensure a secure connection.
