Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Wear protective gloves and eyewear.

2. Check and Top Off Coolant

Sub-steps:
- Open the hood and locate the coolant reservoir.
- Remove the cap carefully to avoid any hot steam.
- If the coolant level is low, add the appropriate coolant mixture (usually a 50/50 mix of antifreeze and distilled water) to the recommended level.
Tools Required: Funnel, coolant

3. Inspect and Replace Thermostat

Sub-steps:
- Disconnect the negative battery terminal to prevent electrical shorts.
- Drain the coolant from the radiator using the drain plug.
- Remove the thermostat housing by unscrewing the bolts and disconnecting hoses.
- Replace the old thermostat with a new one, ensuring the gasket is also replaced.
- Reassemble the thermostat housing and refill the cooling system with coolant.
Tools Required: Socket set, wrench, gasket scraper
Safety Warnings: Allow the engine to cool completely before working on the cooling system.

4. Check and Replace Radiator Fan

Sub-steps:
- With the engine running, observe the radiator fan operation. If it does not engage, remove the fan assembly.
- Test the fan with a multimeter for continuity.
- If faulty, replace the fan with a new one and reassemble.
Tools Required: Multimeter, socket set

5. Inspect and Repair Leaks

Sub-steps:
- Use a pressure tester to identify leaks in the cooling system.
- Replace any damaged hoses or components found during inspection.
- Tighten any loose connections and ensure all clamps are secure.
Tools Required: Pressure tester, replacement hoses
