Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool before starting work to avoid burns.
Disconnect the battery to prevent electrical issues.

2. Check and Refill Coolant

Tools Required: Coolant, funnel
Open the coolant reservoir cap carefully.
If the coolant level is low, use a funnel to add the appropriate coolant mixture until it reaches the proper level.
Replace the cap securely.

3. Inspect and Replace Thermostat (if faulty)

Tools Required: Socket set, coolant catch pan, new thermostat, gasket, gasket sealer
Drain the coolant from the radiator into a catch pan to prevent spills.
Remove the thermostat housing (usually located at the engine block).
Take out the old thermostat and inspect it for proper sealing and operation.
Install the new thermostat with a new gasket, applying gasket sealer if required.
Refill the cooling system with coolant and check for leaks.

4. Inspect and Replace Radiator Fan (if faulty)

Tools Required: Socket set, new radiator fan
Disconnect the electrical connector from the radiator fan.
Remove the mounting bolts that secure the fan to the radiator.
Replace with a new fan, ensuring it is mounted securely and reconnect the electrical connector.

5. Test the Cooling System

Tools Required: Pressure tester (optional)
Start the engine and allow it to reach operating temperature while monitoring the temperature gauge.
Check for leaks around the thermostat and radiator.
If overheating persists, consider pressure testing the system to identify hidden leaks.
