Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.

2. Check and Refill Coolant

Open the coolant reservoir cap carefully.
Inspect the coolant level; if low, add the manufacturer-recommended coolant to the appropriate level.
Replace the cap securely.

3. Inspect and Replace Thermostat

Disconnect the negative battery terminal.
Drain the coolant from the radiator using the drain plug.
Remove the thermostat housing bolts with a socket set.
Take out the old thermostat and inspect for damage.
Install a new thermostat, ensuring correct orientation.
Reassemble the thermostat housing and tighten bolts to manufacturer torque specifications.

4. Examine and Repair Leaks

Visually inspect all hoses and connection points for leaks.
Replace any damaged hoses or clamps as necessary.
If leaks are found in the radiator, consider replacing the radiator.

5. Test and Replace Cooling Fan

Reconnect the battery terminal.
Start the vehicle and allow it to idle until the temperature gauge rises.
Check if the cooling fans activate at the appropriate temperature. If not, test the fan relay and replace the fan if faulty.
