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.
