Radiator Caps

  • Radiator Caps are designed to seal the top of the radiator filler neck to prevent coolant loss, pressurise the cooling system and raise the boiling point of the coolant.
  • Radiator Caps are manufactured using either metal or plastic design depending on the vehicle manufacturer’s specifications.
  • Tridon offers an extensive range of radiator caps covering both metal and plastic designs suitable for use on sealed recovery or open non recovery vehicle cooling systems.
  • In a sealed recovery system the cap (double seal) allows coolant to flow to and from the recovery or expansion tank, maintaining the integrity of the cooling system.
  • A non recovery system does not have a recovery or expansion tank; therefore a non recovery cap (single seal) only allows the release of coolant and return of air to the system.
  • A non recovery cap cannot be used on a recovery system.
  • The radiator cap must be compatible with the vehicle cooling system; the Tridon radiator cap range has been carefully researched and engineered to suit each specific application.
  • Please refer to the Tridon Part Finder for the correct radiator cap for your application.
