Solution
1. Preparation
  • Ensure the engine is cool before beginning any work.
  • Gather tools and parts necessary for the repair.
  • Disconnect the battery to prevent electrical issues.
2. Coolant Level Check
  • Sub-steps:
    1. Open the hood and locate the coolant reservoir.
    2. Verify that the coolant level is between the minimum and maximum marks.
    3. If low, add a suitable coolant mix (typically a 50/50 mix of water and Honda Genuine coolant).
3. Inspect Radiator and Hoses
  • Sub-steps:
    1. Visually inspect the radiator for any signs of damage or corrosion.
    2. Check all hoses for cracks, bulges, or leaks.

4. Test Radiator Fan
  • Sub-steps:
    1. Turn on the air conditioning and listen for the radiator fan to activate.
    2. If the fan does not operate, check the fan fuse and relay.
    3. Replace the fan motor if it is non-functional.
5. Thermostat Inspection
  • Sub-steps:
    1. Remove the thermostat housing.
    2. Inspect the thermostat for proper operation (it should open at the specified temperature).
    3. Replace the thermostat if it is stuck closed.
6. Water Pump Inspection
