Solution

1. Preparation

Gather tools required: socket set, coolant, OBD-II scanner, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Refill Coolant

Open the hood and locate the coolant reservoir.
If the coolant is low, remove the cap carefully to avoid pressure release.
Pour the appropriate coolant (check owner's manual for specifications) until the recommended level is reached.
Replace the cap securely.

3. Inspect and Replace Thermostat (if faulty)

Disconnect the battery to ensure safety.
Drain the coolant from the radiator using the drain plug.
Remove the thermostat housing by unscrewing the bolts (typically requires a socket set).
Take out the old thermostat and visually inspect for damage or jamming.
Install the new thermostat (ensure correct orientation) and torque bolts to manufacturer specifications.
Refill the radiator with coolant and replace the drain plug.

4. Check Radiator Fan Operation

Reconnect the battery.
Start the engine and activate the air conditioning to engage the radiator fan.
Ensure the fan is operational; if not, inspect the fan motor and wiring.

5. Inspect for Leaks

Visually inspect all hoses, the radiator, and the water pump for any signs of leaks or wear.
Replace any damaged hoses or seals as necessary.
