Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, coolant, thermometer, safety goggles, gloves.
Ensure the engine is cool before starting to avoid burns.

2. Coolant Level Check

Remove the radiator cap carefully to prevent steam burns.
Inspect the coolant level; refill if low using the specified coolant type (Honda Genuine Type 2 Coolant).
Check for contamination in the coolant and flush if necessary.

3. Thermostat Replacement

Disconnect the negative battery terminal.
Drain the coolant from the radiator.
Remove the engine cover if obstructing access.
Locate the thermostat housing, detach the hoses, and unbolt the housing.
Replace the old thermostat with a new one, ensuring the orientation is correct.
Reassemble and refill the system with coolant.

4. Water Pump Inspection/Replacement

If the water pump is suspected to be faulty, drain the coolant.
Remove the serpentine belt by loosening the tensioner.
Unbolt the water pump from the engine block and remove it.
Install the new water pump, ensuring to use a new gasket.
Reconnect the serpentine belt and refill the cooling system.

5. Radiator Inspection

Check the radiator and condenser for clogs or leaks.
Clean any debris or obstructions from the front of the radiator.
If damaged or leaking, replace the radiator with a new one.
