To which level should the antifreeze be added in the LaCrosse?

The antifreeze in the LaCrosse should be added to the radiator. First, loosen the screw at the bottom of the car to drain the antifreeze, then open the radiator cap in the engine compartment to add new antifreeze. It is recommended to replace the antifreeze every two years. Antifreeze prevents the coolant from freezing and expanding during cold winter parking, which could crack the radiator or damage the engine cylinder block or head. When replacing antifreeze, try to use the same type of antifreeze. If switching to a different type, it is advisable to completely drain the old antifreeze before adding the new one. The full name of antifreeze should be antifreeze coolant, which is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding during cold winter parking, which could crack the radiator or damage the engine cylinder block.
When dealing with coolant refill in my Buick LaCrosse, I learned that the coolant reservoir is usually located on the left side or front of the engine compartment, with clear Max and Min indicator lines. Refilling must be done when the engine is cold—meaning after the engine has cooled down for at least 30 minutes after turning off the car. Never attempt this when the engine is hot, as high temperature and pressure can cause the coolant to spray out and cause injury. Fill only between the Min and Max lines—avoid overfilling beyond the Max line, as this can cause the expansion tank to burst. I once slightly overfilled mine, leading to leaks and unnecessary repair costs. Also, always use the coolant type recommended by Buick for the LaCrosse; avoid mixing different brands to prevent chemical reactions that could cause blockages. Regularly check the coolant level—if it frequently drops, there might be a leak requiring prompt inspection and repair. In short, safety first—don’t take it lightly.
As a newbie who recently bought a LaCrosse, I was quite confused when learning how to add coolant. The coolant for the LaCrosse should be added to the reservoir tank next to the radiator, not directly into the engine. The tank usually has "Coolant" written on it or a water drop icon, and it's semi-transparent to easily check the fluid level. Always wait for the car to cool down before adding coolant for safety, then unscrew the cap and pour the liquid in. The ideal fluid level should be between the Min and Max marks—if it's below Min, add more; if it's above Max, remove excess to prevent overflow. I wasn’t careful at first and tried adding coolant while the engine was hot, nearly burning myself. Later, I developed a habit of checking regularly: glancing at the fluid level every time I wash the car or refuel. Coolant not only prevents freezing but also protects the engine from overheating. Proper maintenance can save you from repair headaches.
