Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check and Refill Coolant

Locate the coolant reservoir and radiator cap.
If low, top off with the appropriate type of coolant (Honda Genuine Type 2 Coolant).
Replace the radiator cap securely.

3. Inspect and Replace the Thermostat (if faulty)

Drain coolant from the radiator into a suitable container.
Remove the thermostat housing bolts using a socket set.
Take out the old thermostat and inspect for signs of failure (sticking or corrosion).
Install a new thermostat (make sure it is oriented correctly).
Reattach the housing and torque bolts to the manufacturer's specification (typically around 10-12 ft-lbs).

4. Check and Repair Radiator Fan

Inspect the fan operation by turning on the ignition and observing if the fan activates when the engine reaches operating temperature.
If the fan does not operate, check the fan relay and fuse.
Replace the radiator fan if faulty.

5. Flush and Clean the Radiator

Use a radiator flushing solution to remove any blockages.
Connect a garden hose to the lower radiator hose to flush out debris.
Refill with the correct coolant mixture after flushing.

6. Reassemble and Test

Reconnect the battery terminal.
Start the engine and allow it to reach operating temperature while monitoring the temperature gauge.
Check for leaks and ensure proper operation of the cooling system.
