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. Inspect and Replace Coolant

Sub-steps:
1. Remove the coolant reservoir cap and check the level.
2. If low, add a 50/50 mix of coolant and distilled water.
3. Inspect for signs of coolant leaks around hoses and connections.
4. If any leaks are found, replace affected hoses or components.

3. Check and Clean Radiator

Sub-steps:
1. Remove any debris blocking the front of the radiator.
2. Use compressed air to clean the radiator fins.
3. Inspect for any bent fins that might restrict airflow and gently straighten them.

4. Test and Replace Cooling Fans

Sub-steps:
1. Turn on the vehicle and monitor the cooling fans.
2. If fans do not activate, test with a multimeter for electrical continuity.
3. If faulty, remove the cooling fan assembly and replace it.
4. Reconnect the electrical connector and ensure proper operation.

5. Verify Coolant Circulation

Sub-steps:
1. Start the engine and allow it to reach operating temperature.
2. Check the upper radiator hose for heat. It should become hot as the engine warms.
3. If it remains cool, the thermostat may be stuck closed; consider replacing it.
