OEM Honda NSX-R Radiator Cap

A radiator cap in a Honda NSX is a small but critical component of the car’s cooling system. It is located on the top of the radiator and is responsible for maintaining the proper pressure in the cooling system. The radiator cap is designed to hold a specific amount of pressure, which helps to raise the boiling point of the coolant, allowing the engine to run at higher temperatures without overheating.

The radiator cap is typically made of plastic or metal and it has a spring-loaded valve that opens and closes to control the pressure in the cooling system. It also has a pressure rating, which indicates the maximum pressure that the cap can safely handle.

The radiator cap is designed to be easy to access and maintain, it can be easily removed for cleaning or replacement if necessary. It is also designed to be durable and resistant to corrosion, which helps to ensure that the coolant system is working efficiently and prolongs the life of the engine.

It is important to have a functional radiator cap to avoid overheating, overheating can cause serious damage to the engine.
