Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work.
Disconnect the battery to prevent electrical shorts.

2. Coolant Level Adjustment

Remove the coolant reservoir cap.
If low, add the appropriate type of coolant (refer to owner's manual for specifications).
Replace the cap securely.

3. Radiator Fan Inspection and Repair

Tools Required: Multimeter, socket set
Check the wiring and connectors to the radiator fan for damage or disconnection.
Use a multimeter to test the fan motor for continuity.
If the fan is inoperative, replace it by:
- Disconnecting the wiring harness.
- Removing the mounting bolts.
- Installing the new fan and reconnecting the wiring.

4. Thermostat Replacement (if faulty)

Tools Required: Socket set, gasket scraper
Remove the upper radiator hose from the thermostat housing.
Unbolt the thermostat housing and remove the old thermostat.
Clean the mating surfaces with a gasket scraper.
Install the new thermostat and gasket.
Reattach the housing and upper radiator hose.

5. Cooling System Flush

If the coolant is contaminated, perform a coolant flush:
- Use a flush chemical as per the manufacturer's instructions.
- Disconnect the lower radiator hose and drain the old coolant.
- Reconnect the hose, fill with clean water, and run the engine to circulate.
- Drain again and refill with the correct coolant mixture.

6. Final Checks

Reconnect the battery.
Start the engine and monitor the temperature gauge.
Ensure the radiator fan operates correctly.
