Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repair.

2. Check and Replace Coolant

Tools Required: Coolant funnel, container for old coolant
Sub-steps:
1. Remove the radiator cap carefully, ensuring the engine is cool to avoid burns.
2. Inspect coolant quality; if it's dirty or low, drain it into a suitable container.
3. Replace with manufacturer-recommended coolant, ensuring proper mixture ratio.
4. Reinstall the radiator cap securely.

3. Inspect and Replace Thermostat

Tools Required: Socket set, torque wrench, gasket scraper
Sub-steps:
1. Locate the thermostat housing (typically at the engine block near the upper radiator hose).
2. Disconnect the hoses connected to the thermostat housing.
3. Remove the housing bolts and lift the housing away.
4. Remove the old thermostat and clean the mating surfaces.
5. Install the new thermostat, ensuring correct orientation.
6. Reattach the housing and secure the bolts to the manufacturer's torque specifications.

4. Test Cooling Fan Operation

Tools Required: Multimeter
Sub-steps:
1. Reconnect the battery and start the engine.
2. Allow the engine to idle and monitor the temperature gauge.
3. Use a multimeter to check the fan's electrical supply when the temperature reaches a preset level.
4. If the fan does not turn on, inspect the relay and wiring for faults.
