Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and allow the engine to cool completely.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Coolant Level Check

Remove the radiator cap and inspect the coolant level.
If low, top off with the recommended coolant type (Honda Genuine Type 2 or equivalent).

3. Inspect and Replace Thermostat

Drain the coolant from the radiator using a drain pan.
Remove the thermostat housing by unscrewing the bolts (torque to manufacturer specifications).
Replace the thermostat with a new one, ensuring it is oriented correctly.
Reinstall the thermostat housing and secure it with bolts.

4. Check and Replace Radiator Cooling Fans

Disconnect the electrical connectors from the cooling fans.
Remove the fan assembly by unscrewing the mounting bolts.
Inspect the fans for damage; replace if necessary.
Reinstall the fan assembly and reconnect electrical connectors.

5. Flush and Refill Cooling System

With the radiator cap off, fill the system with a mixture of coolant and water (50/50).
Start the engine and allow it to reach operating temperature while monitoring the coolant level.
Top off as necessary and replace the radiator cap securely.
