Here's a general procedure. Consult your owner's manual for specific details and diagrams relevant to your Durango's model:
1. Preparation:
* Safety First: Wear safety glasses. Have a rag handy to clean up any spilled battery acid.
* Gather Tools: You'll likely need a wrench (size will depend on the cable clamp – probably a 10mm or 13mm), possibly a socket wrench, and possibly a screwdriver (depending on how the cable is routed and secured).
* Disconnect the Negative Cable: Locate the negative (-) battery terminal (usually black). Use your wrench to loosen and remove the clamp securing the negative cable. Move the cable away from the battery and secure it somewhere it can't accidentally contact the positive terminal.
2. Accessing the Positive Cable:
* Locate the Positive Cable: The positive (+) battery cable (usually red) is connected to the positive terminal of the battery. Trace it from the battery to where it connects to the starter or other components. You might need to remove some plastic shrouding or other parts to get better access. Pictures or diagrams in your owner's manual will be extremely helpful here.
* Identify Clamps and Connections: The positive cable might have multiple connection points along its length, including the battery terminal and potentially connections to the starter solenoid or other components. Take note of how these are connected.
3. Removing the Positive Cable:
* Loosen the Clamps: Use your wrench to carefully loosen the clamps securing the positive cable at each connection point. Start at the battery terminal and work your way along the cable. Be gentle but firm to avoid damaging the cable or its connections.
* Disconnect the Cable: Once the clamps are loose, carefully disconnect the cable from each connection point.
4. Installing the New Cable:
* Connect the New Cable: Attach the new positive cable to each connection point, ensuring a secure and tight connection at each clamp. Make sure to match the new cable's routing to the original cable's path. This is where the pictures/diagrams from your owner's manual will be most helpful.
* Tighten the Clamps: Use your wrench to firmly tighten all the clamps.
5. Final Steps:
* Reconnect the Negative Cable: After ensuring all connections are secure and the positive cable is properly routed, reconnect the negative (-) battery cable to its terminal. Tighten the clamp firmly.
* Test the System: Start your Durango's engine to verify that the new cable is functioning correctly. Check for any unusual noises or behaviors.
* Clean Up: Clean any battery acid spills and dispose of any old parts appropriately.
Important Considerations:
* Cable Size: Ensure the new cable is the correct gauge (thickness) for your Durango. Using an incorrect gauge can lead to overheating and potential electrical problems. The correct gauge should be stamped on the old cable, and it is crucial to match this.
* Corrosion: Clean the battery terminals and cable ends with a wire brush before connecting the new cable. This improves conductivity and prevents future corrosion.
* Professional Help: If you are uncomfortable performing this repair yourself, consult a qualified mechanic. Improperly installing the battery cable can lead to electrical damage or even fire.
Remember, this is a general guide. Always refer to your vehicle's repair manual for specific instructions and diagrams tailored to your 2002 Dodge Durango. The layout and access points can vary slightly depending on the specific trim level and configuration.
