Where is the water filler port for the GL8 radiator?

Open the hood, and you will find a white container in the upper left corner of the engine compartment, which is the water filler port. Below is some relevant information: 1. Configuration: The new generation Buick GL8 family is equipped with the latest OnStar full-time online assistant, covering over 50 main services across 5 major categories, including remote control, remote vehicle status viewing, and vehicle condition alerts. It also provides users with 100GB of "OnStar 4G in-car application lifetime free data" service per year. 2. Body dimensions: The new generation Buick GL8 Avenir family has body dimensions of 5219mm × 1878mm × 1799mm, with a wheelbase of 3088mm.
I usually drive a GL8 to pick up clients, so I'm very familiar with this vehicle. The water filler port is located in the engine compartment. After opening the hood, look towards the front left side—you'll see a white plastic cap, usually marked with a wavy pattern resembling a radiator. Remember to wait until the engine has completely cooled down before adding water, otherwise high-temperature steam may spray out and burn your hand. Using a funnel makes refilling easier and prevents spills onto the engine. After refilling, start the engine and let it circulate for a few minutes, then turn it off and check whether the fluid level is between the MIN and MAX marks. I recommend regularly inspecting the coolant condition—if its color becomes cloudy or contains impurities, it's time for a replacement.
