Radiator Cap

The radiator cap is a vital component of the engine cooling system, designed to maintain the correct pressure in the radiator and coolant reservoir. It seals the system, allowing coolant to circulate efficiently while raising the boiling point to prevent overheating. A properly functioning radiator cap also releases excess pressure safely to the overflow tank, ensuring system balance and protecting the engine from heat damage.
