TRD Radiator Cap
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.
All vehicles manufactured after the vehicles shown in the table below are N type. (Cannot be used on vehicles manufactured earlier than those in table below.)
Caution: 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).
