Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Coolant Level Check

Open the hood and locate the coolant reservoir.
If the coolant level is low, top it up with the manufacturer-recommended coolant mixture.
Check for leaks around hoses and connections.

3. Inspect Cooling Fans

Reconnect the battery and start the vehicle.
Turn on the HVAC system to the highest setting to engage fans.
Observe if the electric cooling fans activate as the engine reaches operating temperature.
If fans do not operate, replace the cooling fan assembly.

4. Thermostat Replacement

Drain coolant from the system using a drain pan.
Disconnect the hose connected to the thermostat housing.
Remove the thermostat housing bolts and take out the old thermostat.
Install a new thermostat, ensuring it is oriented correctly.
Reattach the housing and reconnect hoses.

5. Radiator Inspection

Inspect the radiator for debris or blockage.
Clean any obstructions from the radiator fins using compressed air or a soft brush.
If the radiator is clogged internally, consider replacing it.

6. Final System Check

Refill the cooling system with the proper coolant.
Bleed the cooling system to remove any air pockets.
Reconnect the battery and run the engine to monitor the temperature gauge.
