Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, coolant funnel, hose clamps, torque wrench, multimeter.
Allow the engine to cool before starting work.
Disconnect the battery to prevent electrical shorts.

2. Coolant System Inspection

Sub-steps:
1. Remove the engine cover if necessary to access the coolant reservoir.
2. Inspect the coolant reservoir for cracks or leaks; replace if damaged.
3. Check the condition of the coolant; if discolored or contaminated, drain and flush the cooling system.
4. Refill the coolant reservoir with the appropriate type of coolant (refer to the owner’s manual for specifications).

3. Thermostat Replacement

Sub-steps:
1. Locate the thermostat housing and remove the bolts using a socket set.
2. Carefully detach the thermostat from the housing.
3. Install the new thermostat, ensuring it is oriented correctly.
4. Reattach the thermostat housing and torque the bolts to the manufacturer’s specifications.

4. Radiator Fan Testing

Sub-steps:
1. Reconnect the battery and start the engine.
2. Allow the engine to reach operating temperature and observe the radiator fan.
3. If the fan does not engage, test the fan motor with a multimeter for voltage.
4. Replace the fan motor if it is not functioning correctly.

5. Final Assembly and Testing

Sub-steps:
1. Ensure all components are securely reattached.
2. Start the engine and monitor the temperature gauge for normal operation.
3. Test drive the vehicle, keeping an eye on the temperature gauge.
