Solution

1. Preparation

Tools Required: Safety gloves, safety goggles, bucket for draining coolant, OBD-II scanner, basic hand tools (sockets, wrenches).
Ensure the engine is cool before starting work to prevent burns.

2. Coolant Level Check

Sub-steps:
1. Open the hood and locate the coolant reservoir.
2. Check the coolant level; if it's low, top it off with the appropriate coolant mixture (Honda Genuine Type 2 Coolant).

3. Inspect Radiator

Sub-steps:
1. Visually inspect the radiator for any visible leaks or damage.
2. If leaks are found, proceed to replace the radiator.

4. Test Thermostat

Sub-steps:
1. Remove the thermostat housing (using a socket set).
2. Submerge the thermostat in boiling water and observe if it opens; if it does not, replace it.

5. Water Pump Inspection

Sub-steps:
1. Check for coolant leaks around the water pump.
2. If leaks are present or the pump is noisy, replace the water pump.

6. Check Cooling Fan Operation

Sub-steps:
1. Start the engine and let it warm up to normal operating temperature.
2. Observe if the cooling fan activates when the engine reaches the specified temperature.
3. If the fan does not engage, check the fan fuse and relay; replace as necessary.
