Drain the flush solution and refill with the correct type of coolant (Honda Genuine Type 2 or equivalent).

3. Replace Thermostat (if necessary)

Remove the thermostat housing (typically located near the engine).
Remove the old thermostat and gasket.
Install the new thermostat with a new gasket, ensuring correct alignment.
Torque the housing bolts to manufacturer specifications (usually around 12-15 lb-ft).

4. Inspect and Replace Radiator Fan (if necessary)

Test the fan with a multimeter for continuity and operation.
If faulty, disconnect the fan electrical connector and remove the fan assembly.
Install the new fan assembly and reconnect the electrical connector.

5. Check and Replace Water Pump (if necessary)
