How often should the coolant in Vios be replaced?

[LaCooper]

Vios coolant should be replaced every two years or 40,000 kilometers. Coolant prevents the freezing of the cooling liquid during cold winter parking, which could otherwise crack the radiator and damage the engine cylinder block. Its full name is antifreeze coolant. Coolant is a specially treated liquid used primarily in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round. The Vios is equipped with a 1.5L naturally aspirated engine and a 5-speed manual transmission, delivering a maximum power of 81 kW and a maximum torque of 138 Nm. It features front-wheel drive, with a MacPherson strut front suspension and a torsion beam rear suspension.
