Trev,

• While the fan clutch detects a temperature lower than 80°C, it remains OFF and the fan revolution speed is constant (1,200 r/min.(rpm)) regardless of the engine speed.
• As the temperature reaches 80°C to 95°C, the fan clutch turns ON gradually and the fan revolution speed increases.
• A temperature exceeding 95°C causes the fan clutch to turn ON and the fan revolution speed to increase in proportion with the engine speed.
• Once the engine speed exceeds a specified one, however, the fan revolution speed becomes constant (3,600 r/min.(rpm)).
