How often should the coolant in the New Santana be replaced?

[LaLilliana]

The maintenance manual for the New Santana specifies that the coolant should be replaced every 45,000 kilometers or 60 months. Coolant, also known as antifreeze coolant, is a liquid composed of antifreeze additives, additives to prevent metal corrosion, and water. It needs to have properties such as antifreeze, anti-corrosion, heat conduction, and resistance to deterioration. The New Santana has a body length, width, and height of 4473mm, 1706mm, and 1469mm respectively, with a wheelbase of 2603mm. The new Santana series is equipped with a 1.5-liter naturally aspirated engine, which delivers 112 horsepower and a maximum torque of 145 Nm. The engine's maximum power is achieved at 6100 rpm, and the maximum torque is reached at 4000 rpm.

Regarding the coolant for the new Santana, I've checked the manual, and the manufacturer recommends replacing it every two years or around 40,000 kilometers. However, I believe the actual driving environment is crucial. If you live in a place like Northeast China where temperatures drop to dozens of degrees below zero, the freezing point of the coolant decreases faster, so it's best to check the coolant's freezing point value in advance. Last time at the repair shop, I saw an old Santana owner who hadn't changed the coolant for three years, resulting in radiator corrosion and leakage. The car broke down on the roadside in the middle of winter, and the repair cost was much higher than replacing the coolant. Nowadays, the coolant reservoirs in new cars are semi-transparent, so you can easily check the fluid level and color by lifting the hood. If it appears cloudy or discolored, you should pay attention. If you frequently drive long distances with the engine operating at high temperatures for extended periods, the protective performance of the coolant degrades faster. In such cases, I definitely wouldn't dare to wait two years before replacing it.
