COOLING SYSTEM


  1. CONSTRUCTION


    1. Water Pump


      1. A rust-resistant water pump rotor made of stainless steel is used.

      2. The water pump sends the engine coolant to the engine coolant distribution pathway located between the left and right banks of the engine block.

    3. Cooling Fan and Fan Shroud


      1. The fan shroud is secured to the radiator without the use of bolts to improve serviceability.

      2. A ring-shaped electric fan is used to ensure efficient cooling performance and quieter operation.
