How to Remove and Install the Battery of Buick GL8?

Steps for removing and installing the battery of Buick GL8: 1. Pull the hood release lever located under the left side of the driver's seat, then open the hood and locate the battery; 2. Remove the nuts of the fixing bracket and the battery protective cover; 3. Disconnect the terminals at both poles; 4. There are fixing screws on the battery that need to be removed. After removal, the battery can be replaced. Note that the tilt angle should not exceed 40 degrees when removing the battery. The GL8 is a business vehicle under the Buick brand, featuring the new-generation Buick wing-style chrome-plated grille, with an elegant and grand appearance. Its body dimensions are 5219mm in length, 1878mm in width, and 1776mm in height, with a wheelbase of 3088mm. In terms of power, the Buick GL8 is equipped with a 2.5L SIDI all-aluminum intelligent direct injection engine featuring dual VVT and in-cylinder direct injection technology, delivering a maximum power of 147kW and a maximum torque of 253Nm, paired with a 6-speed DSS intelligent automatic transmission.

Last time when I helped my neighbor remove the GL8 battery, I found it actually involves five steps: First, wear insulated gloves and use a 10mm socket to loosen the negative terminal clamp (remember, always remove the negative terminal first!). Then, remove the positive terminal in the same way. Once the clamps are loosened, lift them up to remove. When installing the new battery, first secure the base, insert and tighten the positive terminal, and finally connect the negative terminal—at this point, a small spark might jump out, but don’t panic. If the terminals are rusty, remember to clean them with a wire brush until shiny. After installation, test whether the one-touch window reset works. Doing it yourself saves over 300 yuan compared to a repair shop, and the tools only cost 10 yuan to rent a socket.

Having run an auto repair shop for twenty years, I can replace Buick series batteries with my eyes closed. The spacious engine bay of the GL8 actually makes the job easier—first turn the steering wheel all the way to the right to expose the battery location. Prepare a 10mm wrench to remove the negative terminal, and pry open the red protective cover on the positive terminal post. When removing the old battery, be careful not to spill electrolyte on the frame. When installing the new battery, pay attention to the orientation of the terminals. Here’s the key point: the positive cable will click into place when properly tightened. Finally, don’t use excessive force when tightening the negative terminal to avoid stripping the threads.

As a female car owner, I successfully DIYed the GL8 battery replacement and would like to share some safety details: 1. Before removal, ensure the key is at least three meters away from the car—Buick's anti-theft system is sensitive; 2. Prepare baking soda water to neutralize any potential electrolyte leaks immediately; 3. Reversing the disconnection sequence may damage the computer board; 4. After installing the new battery, don’t close the door immediately—test the air conditioning by powering on the car before locking it; 5. Avoid forcing the side handles when removing the old battery. The entire process takes about half an hour, and it’s normal for the fuel consumption display to reset afterward.
