Which component is described as venting excessive pressure buildup from the energy absorber into radiator overflow?

• A. Radiator cap
• B. Overflow valve
• C. Energy absorber vent
• D. Radiator Pressure cap

Answer: (D)

When the energy absorber builds up excess pressure, it needs a controlled way to relieve that pressure without damaging the system. The radiator pressure cap is the device that does this. It is spring-loaded to open at a set pressure and allows coolant to flow into the radiator overflow reservoir, keeping the system pressure within safe limits. This path specifically channels the vented fluid into the radiator overflow, which is why it’s the correct choice. The other options describe related parts that either vent in different ways or serve different roles, but they do not provide the direct pressure-relief path into the radiator overflow.
