Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and disconnect the battery.
Gather coolant and a catch pan for any spilled coolant.

2. Check and Refill Coolant

Remove the radiator cap and check the coolant level.
If low, top off with the manufacturer-recommended coolant.
Inspect for leaks during this process.

3. Replace Thermostat (if faulty)

Remove the thermostat housing using a socket set.
Take out the old thermostat and clean the mounting surfaces.
Install the new thermostat, ensuring correct orientation.
Reinstall the thermostat housing and torque to manufacturer specifications.

4. Inspect and Clean Radiator

Remove any debris and dirt from the radiator fins.
If the radiator is clogged, consider a professional flush or replacement.
Ensure the electric fans are operational; replace fans or fuses if necessary.

5. Check Cooling System Pressure

Use a cooling system pressure tester to check for leaks.
If leaks are found, replace affected hoses or components.
