Your Volvo's radiator cap is a small mechanical device that aids in the regulation of the pressure of the hot coolant in the radiator. The radiator is a reservoir that cools hot coolant before returning it to the engine for cooling. The caps on containers serve as a cover that keeps the liquid inside, but they also serve another purpose. As the temperature of coolant rises, it will eventually boil and turn into vapor. The coolant's boiling point is approximately 212 degrees Fahrenheit, which will rise when under pressure. The radiator cap raises the boiling point of the coolant by about 45 degrees Fahrenheit.

If you have a faulty Volvo radiator cap, you may notice the following symptoms:

  • Coolant leak
  • Reservoir overflow
  • A burst radiator hose
  • Engine overheating

Replacing the radiator cap is a simple task that may only take a few minutes of your time. Allowing the engine to cool before removing the radiator cap is critical, as removing the cap from a hot system can result in sudden coolant spray and severe burns. Pay close attention to the pressure rating on your cap and choose one with the same. When you have a replacement and your engine is cool, simply unscrew the old cap and screw the new one on.
