This thermostat has the operating temperature set lower than normal. It prevents engine power loss by minimizing rapid water-temperature rises under harsh conditions such as during circuit driving.

The use of a flow-control-type valve prevents hunting, thereby achieving rapid stabilization of the water temperature (the engine warms up within a short period). Operating temperature: 68°C (STD.: 76~80°C) Full-throttle acceleration temperature: 81°C (STD.: 90°C).

Vehicle/Engine applications: 02-06 RSX (K20A/A2/A3/Z1), 02-05 Civic Si (K20A3)
