Radiator caps also serve as pressure relief valves. They will prevent excessive pressure. Unchecked high pressure could cause damage to the radiator, heater core, hoses or water pump seal. The pressure cap also prevents radiator hoses and tanks from collapsing.

FEATURES

• A radiator pressure cap keeps the system pressure at 16 PSI, which avoids the coolant from boiling off even when it gets hotter considerably.
• Because liquid expands as it gets hotter, the pressure cap allows coolant to escape to a reservoir tank when it expands. This is to keep a proper amount of coolant in the radiator when it expands.
• The radiator pressure cap prevents trapping of air in the cooling system. The air in the system will cause poor cooling and cause corrosion to the cooling system components.
• The coolant in the external reservoir will be pulled back, leaving no room for air.
• The pressure cap is an important component of the proper working of an engine. it should be periodically inspected and consider a replacement if it fails. Ensure 5o/5o water and anti-freeze agent is used.
