Solution

1. Preparation

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

2. Check Coolant Level

Open the coolant reservoir cap (ensure engine is cool).
If low, top up with the manufacturer-recommended coolant mixture.

3. Inspect and Replace Thermostat

Locate the thermostat housing (usually near the engine).
Remove the bolts using a socket set.
Carefully take out the thermostat and inspect for damage.
Replace with a new thermostat if faulty.
Reassemble the housing and torque bolts to manufacturer specifications.

4. Inspect Radiator Fan

Check if the fan operates when the engine reaches operating temperature.
If not, test the fan motor with a multimeter.
Replace the radiator fan if it fails the test.

5. Check Water Pump

Inspect the water pump for any signs of leakage or damage.
If the water pump is faulty, drain the coolant and remove the pump.
Replace it with a new unit, ensuring proper alignment and torque specifications during reinstallation.
