Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Coolant

Check Coolant Levels:
- Open the coolant reservoir cap and check the level.
- If low, top off with the recommended coolant type (usually a 50/50 mixture of antifreeze and distilled water).
Flush the Cooling System:
- Drain the existing coolant using the drain plug on the radiator.
- Flush the system with clean water until it runs clear, then drain again.
- Refill with the correct coolant mixture.

3. Replace Thermostat

Remove Thermostat:
- Locate the thermostat housing; remove the clamps and hoses connected to it.
- Unbolt the thermostat housing using the appropriate socket size.
Install New Thermostat:
- Place a new thermostat in the housing, ensuring the correct orientation.
- Reassemble the housing and reattach the hoses securely.

4. Inspect and Test Radiator Fan

Check Fan Operation:
- Turn on the ignition without starting the engine.
- Listen for the radiator fan's activation or use a multimeter to test for voltage at the fan connector.
Replace Fan if Necessary:
- If the fan does not operate, remove it by unbolting it from the mounting points.
- Install a new fan and reconnect the electrical connector.
