Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical accidents.

2. Inspect and Replace Coolant

Sub-steps:
1. Open the radiator cap and check coolant level; add manufacturer-recommended coolant if low.
2. If coolant is dirty or contaminated, drain the existing coolant using a drain pan.
3. Flush the cooling system with a coolant flush solution following manufacturer instructions.
4. Refill the system with new coolant to the appropriate level.

3. Replace Thermostat (if necessary)

Sub-steps:
1. Remove the thermostat housing by unscrewing the bolts (use a socket set).
2. Take out the old thermostat and compare it with the new one to ensure correct dimensions.
3. Install the new thermostat, ensuring it is oriented correctly.
4. Reattach the thermostat housing and torque the bolts to specified values.

4. Check and Service Radiator Fan

Sub-steps:
1. Start the engine and let it reach operating temperature; observe the radiator fan operation.
2. If the fan does not engage, check the fan relay and fuses.
3. Replace the radiator fan if it is malfunctioning.
4. Clean any debris around the radiator and ensure proper airflow.
