What are the steps for removing and installing the battery in a Buick GL8?

[DelLincoln]

Here is a step-by-step guide on how to replace the battery: 1. Loosen the negative terminal nut: Open the two fastening buttons on the thermal insulation cover to reveal the red and black insulating caps on the positive and negative terminals. Lift the insulating caps to expose the locking nuts. 2. Remove the negative terminal: Use a wrench or hex socket to loosen the fastening nut on the negative terminal, then gently pry open the fastening block with a flathead screwdriver before pulling out the negative terminal. 3. Remove the positive terminal: Repeat the same process to remove the positive terminal. 4. Remove the locking strap: Unscrew the nut securing the battery's locking strap, release the strap, and then remove the battery. When installing the new battery, simply follow the reverse steps. However, note that when reconnecting the terminals, the order is "positive first, then negative," which is the opposite of the removal sequence. The principle remains the same—to prevent short-circuit risks and ensure safety.
