Steps to change the coolant for Buick Regal: 1. Drain the water from the radiator; 2. Tighten the drain valve and refill with new coolant, then tighten the cap after filling; 3. Start the engine and wait for the electric fan to activate and run, then wait for it to stop automatically; 4. Slowly open the filler cap and top up to the upper mark. The Buick Regal is a mid-to-high-end sedan from Buick, with dimensions of 4843 mm in length, 1856 mm in width, and 1484 mm in height, and a wheelbase of 2737 mm. The new-generation Regal features door panel interiors made of relatively soft synthetic materials, enhancing the overall vehicle's premium feel. Additionally, the winged U-shaped door handle design stands out as one of the interior highlights, adding a sporty element to the cabin.
I've been driving a Buick Regal for many years, and changing the coolant is actually quite simple, but it requires attention to detail. First, always wait until the engine is completely cooled—preferably overnight or for a few hours—otherwise, you risk serious burns. Second, locate the drain plug under the radiator, loosen it with a wrench, and have a large bucket ready to catch the old coolant, as it's toxic and must not be disposed of carelessly. Third, after draining, if the old coolant is very dirty, flush the system with a cleaning solution, but avoid tap water to prevent rust—distilled water is best. Fourth, when adding new coolant, buy a universal type and mix it 50/50 with distilled water, then fill the radiator to the top. Finally, start the engine to let the temperature rise and release any air bubbles, then top up the coolant level as needed. Check for leaks—the whole process takes me about 50 minutes, saving both money and time.
