What maintenance must be performed to ensure the vehicle's cooling system is effective?

To ensure the vehicle's cooling system operates effectively, checking and maintaining proper coolant levels is essential. The coolant, or antifreeze, plays a critical role in regulating the engine temperature by absorbing heat and preventing overheating. If the coolant levels are low, it can lead to inadequate cooling, which may cause engine damage or failure. Regularly monitoring and replenishing coolant ensures that the cooling system functions properly, especially under demanding conditions or during hot weather.

While oil changes, tire rotations, and air filter replacements are important aspects of vehicle maintenance, they primarily address other systems within the vehicle. Oil changes maintain engine health, tire rotations promote even tire wear and handle stability, and air filter changes support the engine's air intake system. However, they do not directly impact the cooling system's efficiency in the same way that maintaining coolant levels does.
