How often should the antifreeze be replaced in the LaCrosse?
2 Answers
The antifreeze in the LaCrosse should be replaced every 2 years or 40,000 kilometers. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold winter parking. Owners should regularly check the coolant level. If the coolant level is found to be below the 'mix' mark, it should be topped up promptly to avoid affecting the engine's cooling efficiency. The LaCrosse is a vehicle under SAIC-GM Buick, with dimensions of 5026mm in length, 1866mm in width, and 1459mm in height, and a wheelbase of 2905mm. The car is equipped with 11 intelligent driving assistance features, including PD pedestrian detection, LKA lane keeping, ACC adaptive cruise control, and CMB collision mitigation.
I recommend changing the antifreeze in the Buick LaCrosse every two to three years or after exceeding 40,000 kilometers. This is primarily because antifreeze deteriorates over time, losing its anti-corrosion and boiling resistance properties. If you live in a dusty area or extreme climate, increase the replacement frequency to approximately every year and a half. Regularly check the antifreeze color - if it appears cloudy, dark, or has sediment, it indicates deterioration and requires immediate replacement. Neglecting this issue may lead to engine overheating or rust, with repair costs starting from several thousand yuan. I suggest having a professional technician conveniently test the conductivity during routine maintenance - it's both efficient and ensures driving safety. Remember to use the manufacturer-recommended antifreeze type and avoid mixing different brands to prevent chemical reactions that could corrode the cooling system.
