A fully functional radiator and cooling system is essential in preventing overheating, which can cause expensive breakdowns and may result in serious engine damage. Modern engines also operate more efficiently within specific temperature ranges. 

Ensuring your cooling system is functioning correctly is vital for maintaining the health and longevity of your vehicle. It prevents the engine from overheating and minimises the risk of costly repairs, reducing wear and tear on critical components. A well-maintained cooling system enhances fuel efficiency, reducing harmful emissions that damage the environment and contributing to a cleaner and safer driving experience.
