Solution

1. Preparation

Tools Required: OBD-II scanner, coolant catch pan, socket set, torque wrench, multimeter, safety goggles, gloves.
Ensure the engine is cool before beginning work to prevent burns.

2. Coolant Replacement

Drain Coolant
- Place a coolant catch pan under the radiator.
- Open the drain valve on the radiator and allow the coolant to fully drain.
Flush System (if necessary)
- Fill the system with water and run the engine until it reaches operating temperature.
- Drain the water, repeating until the coolant runs clear.
Fill with New Coolant
- Mix the appropriate coolant with water as per manufacturer's specifications (usually a 50/50 mix).
- Fill the radiator and expansion tank to the required level.

3. Thermostat Replacement

Remove Thermostat
- Disconnect the negative battery terminal.
- Remove the thermostat housing using a socket set.
- Take out the old thermostat and inspect the sealing surface for damage.
Install New Thermostat
- Position the new thermostat in the housing, ensuring proper orientation.
- Reattach the thermostat housing and torque to the manufacturer's specifications.

4. Radiator Fan Testing

Inspect Wiring and Connections
- Visually inspect the wiring leading to the radiator fan for fraying or disconnection.
- Use a multimeter to test for continuity in the fan motor.
Test Fan Operation
- Start the vehicle and allow it to reach operating temperature.
- Ensure the radiator fan engages when the temperature reaches the designated threshold.
