Solution

1. Preparation

Gather tools and parts before starting the repair.
Ensure the engine is cool to avoid burns.
Disconnect the battery to prevent electrical shorts.

2. Coolant Level Check

Locate the coolant reservoir and remove the cap.
If the coolant is low, top it off with a 50/50 mix of engine coolant and distilled water.
If the coolant was low, look for leaks or other issues.

3. Radiator Inspection

Visually inspect the radiator for any physical damage or blockage.
Clean any debris obstructing airflow through the radiator.

4. Thermostat Replacement

Drain the coolant from the radiator.
Remove the thermostat housing bolts with a socket wrench.
Take out the old thermostat and replace it with a new one, ensuring the correct orientation.
Reinstall the housing and torque bolts to manufacturer specifications (typically 15-20 lb-ft).

5. Radiator Fan Testing

With the engine running, observe if the radiator fans engage when the temperature gauge rises.
If not, test the fan relay and replace if faulty.
Check fan wiring for damage.

6. Flush the Cooling System

If overheating persists, consider flushing the cooling system.
Use a cooling system flush solution as per manufacturer instructions.
Refill with fresh coolant after flushing and ensure no air pockets remain in the system.
