  • Install the new reservoir, securing it with clamps and reconnecting hoses.

B. Hoses

  • Identify and remove any damaged hoses by loosening the clamps.
  • Replace with new hoses, ensuring they are securely clamped.

C. Water Pump

  • Remove any components obstructing access to the water pump (e.g., timing covers).
  • Unbolt the water pump from the engine block.
  • Clean the mounting surface and install a new water pump with a new gasket.
  • Torque the pump bolts to the manufacturer’s specifications.

D. Radiator

  • Disconnect the upper and lower radiator hoses.
