Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Allow the engine to cool before opening the hood to prevent burns.
Gather necessary tools and parts.

2. Check Coolant Levels

Remove the coolant reservoir cap.
Inspect the coolant level; add a 50/50 mix of coolant and distilled water if low.
Replace the cap securely.

3. Inspect Cooling System Components

Hoses:
- Visually inspect all hoses connected to the radiator and engine for damage.
- Replace any damaged hoses.
Thermostat:
- Remove the thermostat housing (typically requires a socket set).
- Test the thermostat by placing it in boiling water to check if it opens.
- If non-functional, replace with a new thermostat.

4. Test and Replace Cooling Fan

Disconnect the cooling fan connector and use a multimeter to check for continuity.
If the fan is faulty, remove it (usually involves removing bolts and unplugging connectors).
Install a new cooling fan and reconnect the electrical connector.

5. Check for Leaks

Use a pressure tester on the cooling system to identify any leaks.
Repair any leaks found, which may involve replacing gaskets or seals.
