The TRD radiator cap increases valve opening pressure up to 1.3kg/cm2 or 1.4kg/cm2 for greater cooling performance.
Upping the valve opening pressure of the pressure regulator on the radiator cap to allow higher radiator pressure increases the boiling point of the coolant, reduces bubbles, improves cooling, and generally maximizes the cooling performance of the radiator. We increased the valve opening pressure of the TRD radiator caps to 127 kpa (1.3 kg/cm2) and 147 kpa (1.5 kg/cm2). Thus, another full-fledged design that arose from racing car development makes its appearance.
There is no TRD radiator cap that can be used in the MR-S (ZZW30), Celica (ZZT230), Duet, Cavalier, Cami, Land Cabin Cruiser 100, Town Ace Noah, Light Ace Noah (CR40/50G), or Estima (TCR/CXR).
