Cool with F.E.W Radiator Cap

The F.E.W Radiator Cap is a crucial component of a vehicle’s cooling system. It regulates the pressure within the radiator and coolant system to maintain optimal pressure levels required for efficient operation of the cooling system. The radiator cap acts as a pressure regulator, ensuring pressure remains within safe limits to prevent coolant boiling and system damage. It also seals the system to prevent coolant from leaking out and air from entering. Overall, the F.E.W Radiator Cap plays a critical role in maintaining the proper functioning of the vehicle’s cooling system, contributing to the overall performance and reliability of the engine.

The F.E.W Radiator Cap represents a vital component within a vehicle’s cooling system, playing a crucial role in maintaining optimal engine temperature and preventing overheating. Here’s an explanation of its function and features:

  1. Pressure Regulation: The F.E.W Radiator Cap regulates the pressure in the vehicle’s cooling system, maintaining a pressure level of around 15 psi to raise the boiling point of the coolant and prevent it from boiling over as it absorbs heat from the engine.
  2. Sealing Mechanism:The F.E.W Radiator Cap has a rubber gasket that ensures a secure fit, preventing coolant leaks and air from entering the system. This maintains the cooling system’s integrity and prevents potential engine damage caused by coolant loss.
  3. Pressure Relief Valve: In addition to regulating pressure, the F.E.W Radiator Cap is equipped with a pressure relief valve or spring-loaded mechanism. This valve is designed to open when the pressure inside the cooling system exceeds a certain threshold, typically around 16-18 psi. By releasing excess pressure, the cap prevents damage to the radiator, hoses, and other components that may occur due to pressure buildup, such as radiator leaks or hose bursts.
  4. Coolant Expansion Reservoir:Some F.E.W Radiator Caps have a built-in coolant expansion reservoir that collects excess coolant preventing it from spilling or causing coolant loss. The collected coolant is then drawn back into the radiator as the engine cools down, ensuring the system remains at the proper level.
