Solution

1. Preparation

Tools Required: Socket set, screwdriver set, OBD-II scanner, coolant pressure tester, multimeter.
Allow the engine to cool down before starting any work.
Disconnect the negative battery terminal for safety.

2. Check and Refill Coolant

Remove the radiator cap and inspect the coolant level in the radiator.
If low, add the appropriate type of coolant mixed with water (consult the owner's manual for specifications).
Replace the radiator cap securely.

3. Inspect and Replace Thermostat (if faulty)

Locate the thermostat housing (usually near the engine).
Remove the hoses connected to the thermostat housing using the socket set.
Unbolt the thermostat housing and remove the old thermostat.
Clean the mating surfaces and install a new thermostat, ensuring it is oriented correctly.
Reassemble the housing and hoses, tightening to manufacturer specifications (consult service manual for torque values).

4. Check Electric Cooling Fans

Reconnect the battery terminal.
Start the vehicle and allow it to reach operating temperature.
Observe the cooling fans; they should engage when the engine temperature rises.
If they do not operate, use a multimeter to test for power at the fan connector. If no power is present, check the fan relay and fuses.

5. Inspect Water Pump

Check for any coolant leaks around the water pump and listen for any unusual noises.
If the water pump is leaking or not functioning, it will need to be replaced. Remove the serpentine belt, unbolt the water pump, and install a new one. Ensure proper torque specifications are followed.
