Chevrolet Captiva Service & Repair Manual: Battery Cable R&R

Removal

Warning: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the battery ground cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
For Vehicles equipped with OnStar® with Back-Up Battery: The Back-Up Battery is a redundant power supply to allow limited OnStar® functionality in the event of a main vehicle battery power disruption to the VCIM (OnStar® module). Do not disconnect the main vehicle battery or remove the OnStar® fuse with the ignition key in any position other than OFF. Retained accessory power should be allowed to time out or be disabled (simply opening the driver door should disable retained accessory power) before disconnecting power. Disconnecting power to the OnStar® module in any way while the ignition is ON, or with retained accessory power activated, may cause activation of the OnStar® Back-Up Battery system and will discharge and permanently damage the Back-Up Battery. Once the Back-Up Battery is activated, it will stay on until it has completely discharged. The Back-Up Battery is not rechargeable and once activated, the Back-Up Battery must be replaced.

Replacing the battery cables in a Chevrolet Captiva is a crucial maintenance task outlined in the Chevrolet Captiva (2006-2018) Service & Repair Manual. These cables are essential for transferring electrical power from the battery to various components of the vehicle's electrical system, including the starter, alternator, and accessories.

Start by parking the vehicle on a level surface and engaging the parking brake. Ensure the engine is turned off before beginning the Battery Cable R&R (Removal and Replacement) process. Safety gloves and eye protection should be worn throughout the procedure.

Locate the battery cables connected to the battery terminals. There are typically two cables: the positive (+) cable, usually red, and the negative (-) cable, usually black. Inspect both cables for any signs of damage, corrosion, or wear that may necessitate replacement.

To remove the old battery cables, start with the negative (-) cable. Use a suitable wrench or socket to loosen and remove the terminal clamp nut securing the negative cable to the battery terminal. Carefully detach the cable from the terminal, taking note of its routing and connections to other components.

Next, proceed to remove the positive (+) cable using the same method. Loosen and remove the terminal clamp nut, then detach the cable from the battery terminal.

Inspect the battery terminals for any corrosion or buildup that may hinder electrical conductivity. Clean the terminals using a wire brush or terminal cleaner to ensure a good connection with the new cables.

Install the new battery cables by reversing the removal steps. Begin with the positive (+) cable, attaching it to the positive battery terminal and tightening the terminal clamp nut securely. Repeat this process for the negative (-) cable, ensuring it is securely attached to the negative battery terminal.

After installing the new cables, perform a visual inspection to confirm that all connections are secure and there are no loose components. Start the engine and check for proper electrical system functionality, including lights, accessories, and starting capability.

The Battery Cable R&R procedure outlined in the Service & Repair Manual ensures reliable electrical power distribution in the Chevrolet Captiva, maintaining optimal vehicle performance and electrical system integrity. Regular inspection and replacement of battery cables as needed contribute to the vehicle's overall reliability and safety.
