Solution

1. Preparation

Gather necessary tools: flashlight (if needed), clean cloth.
Ensure the vehicle is parked on a level surface and the engine is completely cool.

2. Locate and Inspect the Coolant Reservoir

Open the hood and secure it with the prop rod.
Identify the coolant reservoir, which is usually a translucent plastic tank near the radiator.
Check the side of the reservoir for the MIN and MAX level indicators.

3. Check Coolant Level

If the coolant level is below the MIN mark:
- Add Coolant: Remove the cap by turning it counterclockwise.
- Use a funnel to pour the appropriate coolant mixture (50% antifreeze and 50% distilled water) until it reaches the MAX level.
- Replace the cap securely by twisting it clockwise.

4. Inspect for Leaks

Check hoses and the radiator for any signs of leakage.
Wipe any spilled coolant from the reservoir and surrounding areas.
