Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is cool.
• Gather all necessary tools and parts.
• Disconnect the vehicle's battery to prevent any electrical issues.

2. Inspect and Refill Coolant

• Locate the coolant reservoir and remove the cap.
• If low, refill the coolant with the manufacturer's recommended type, ensuring no air pockets.
• Check the radiator cap for a proper seal and replace if necessary.

3. Check for Leaks

• Visually inspect hoses, fittings, and the radiator for any signs of coolant leaks.
• If leaks are found, replace damaged hoses or components.
• Use a pressure tester to identify leaks in the cooling system.

4. Replace Thermostat

• Drain the coolant from the system.
• Remove the thermostat housing using a socket set.
• Replace the thermostat with a new one, ensuring proper orientation.
• Reinstall the housing and tighten to the manufacturer's torque specifications.

5. Test Cooling Fans

• Reconnect the battery.
• Start the engine and monitor the cooling fans for operation.
• If fans do not activate, test the fan relay and replace if faulty.

6. Replace Coolant Temperature Sensor

• Locate the coolant temperature sensor and disconnect the electrical connector.
• Remove the sensor using appropriate tools.
• Install the new sensor and reconnect the electrical connector.
