Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work to prevent burns.
Disconnect the battery for safety.

2. Check and Refill Coolant

Locate the coolant reservoir and remove the cap.
Inspect the coolant level; if below the minimum mark, add the appropriate type of coolant (Honda Genuine Type 2).
Recheck the level after running the engine for a few minutes and add more if necessary.

3. Inspect and Replace Thermostat (if faulty)

Drain the coolant from the radiator into a clean container.
Remove the upper radiator hose from the thermostat housing.
Unbolt the thermostat housing and remove the old thermostat.
Clean the mating surfaces and install a new thermostat with a new gasket.
Reassemble the housing and reconnect the upper radiator hose.

4. Check and Replace Water Pump (if necessary)

Remove any components obstructing access to the water pump (e.g., belts).
Unbolt the water pump from the engine and remove it.
Clean the mounting surface and install a new water pump using a new gasket.
Reassemble any components removed.

5. Check Radiator Fan Operation

Reconnect the battery and start the engine.
Allow the engine to reach operating temperature and observe if the radiator fan engages.
If the fan does not operate, replace the fan motor or check electrical connections.
