Solution

1. Preparation

Tools Required: Socket set, coolant refill funnel, multimeter, OBD-II scanner.
Safety Warnings: Allow the engine to cool before opening the coolant reservoir. Wear gloves and safety goggles.

2. Check Coolant Level

Locate the coolant reservoir.
Remove the cap and visually inspect the coolant level against the markings on the reservoir.
If low, proceed to refill the coolant.

3. Refill Coolant

Use the recommended coolant type (refer to owner’s manual for specifications).
Using a funnel, slowly pour the coolant into the reservoir until it reaches the appropriate level.
Replace the coolant reservoir cap securely.

4. Inspect for Leaks

Start the engine and let it reach operating temperature.
Observe the area around the coolant reservoir and under the vehicle for any signs of leaks.
If leaks are found, identify the source (e.g., hoses, radiator, or water pump) for further action.

5. Replace Faulty Components (if necessary)

If the coolant temperature sensor is faulty, disconnect the battery, remove the sensor, and install a new one.
Ensure all connections are secure and components are torqued to manufacturer specifications.
