How often should the coolant be changed in a Sail?

[LunaAnn]

The coolant in a Sail should be changed every 30,000 kilometers or 18 months. Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It provides excellent performance features such as freeze protection in winter, boil-over prevention in summer, and year-round anti-scaling and anti-corrosion properties. The Sail is a compact car produced by Chevrolet, with body dimensions of 4300mm in length, 1735mm in width, and 1503mm in height, and a wheelbase of 2500mm. In terms of exterior design, the Sail features a distinctive waistline that gives the side profile a three-dimensional and powerful appearance. The side character line extends from the front fascia all the way to the rear of the vehicle, creating a smooth and dynamic silhouette with a lower front and higher rear stance.
