      • Replenish coolant with a 50/50 mixture of antifreeze and distilled water, or as specified for your operating conditions.

  2. Water Pump, Hoses, and Radiator

    • Inspection:
      • Inspect the water pump for leaks or unusual noises, such as squealing, which may indicate bearing wear.
      • Check hoses for cracks, bulges, or loose connections.
      • Examine the radiator or heat exchanger for corrosion, blockages, or damaged fins.
    • Actions:
      • Replace worn hoses, tighten connections, and clean the radiator to ensure optimal flow and heat dissipation.
