What is the replacement interval for coolant?

[DiJoel]

The replacement interval for coolant is generally every 2 years or approximately 60,000 kilometers. Functions of coolant: When parking in cold winter, it prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head. In high summer temperatures, it effectively prevents boiling and avoids overheating. Coolant provides freeze protection in winter, boil protection in summer, and year-round protection against scale and corrosion, ensuring the engine operates within the normal temperature range. Checking coolant level: To check if the car's coolant level is sufficient, observe the MIN and MAX marks on the car's radiator. The coolant level should remain between the MAX and MIN marks for normal operation - neither too much nor too little. If the level is below MIN, it indicates insufficient coolant and requires topping up.
