How often should the coolant in the Regal be changed?
3 Answers
Regal coolant should be changed approximately every two years or 40,000 kilometers. The method for changing the coolant is as follows: 1. Open the vehicle's engine hood, and you can see the coolant reservoir in the upper right corner; 2. Open the coolant drain plug under the radiator to drain the old coolant; 3. Add new coolant, tighten the cap, and the coolant replacement is complete. Taking the 2020 Regal Elite model as an example, its body dimensions are: length 4904mm, width 1863mm, height 1461mm, wheelbase 2829mm, fuel tank capacity 55 liters, trunk capacity 441 liters, and curb weight 1430kg.
As a Regal owner for several years, I'd like to share some experience: The coolant replacement interval is typically every two years or after driving about 30,000 kilometers. You should check your owner's manual for specifics, as different model years may have slight adjustments. Coolant doesn't just prevent freezing - it also provides cooling and anti-corrosion functions. If replacement is delayed, it can deteriorate and corrode pipelines, leading to engine overheating or even cylinder explosion. My personal experience was coolant failure during a summer road trip when the dashboard temperature warning light came on - fortunately no major accident occurred. I recommend checking the fluid level and color before winter. If it appears cloudy or the level is low, replace it immediately. Always choose OEM or compatible brands, and never mix different types to avoid problems. Regular maintenance makes your car more durable.
As a newbie who just got my Buick Regal, I consulted experienced drivers about coolant. Generally, it should be replaced every two years or so. The Regal manual specifies replacement every 2 years or 25,000 kilometers – don't cut corners by delaying it. Coolant protects the engine from overheating and freezing in winter. Deteriorated coolant may leak or corrode components, increasing repair risks. Routine checks are simple: inspect the coolant reservoir level and clarity when the engine is cold. If it appears cloudy or has sediment, replacement is needed. For safe driving, I make it a habit to check the level every six months during minor maintenance to avoid breakdowns during family trips. Always use dedicated coolant – never mix it with tap water or different types randomly.
