Diagnostic Steps

Park the vehicle on a level surface and turn off the engine to allow it to cool.
2
Open the hood and locate the coolant reservoir, typically translucent and marked with minimum and maximum level indicators.
3

5

Solution

1. Preparation

Gather necessary tools and materials:
- Coolant (refer to the owner’s manual for specifications, usually a 50/50 mix of antifreeze and water)
- Funnel
- Clean cloth or rag
Ensure the engine is completely cool to avoid burns and pressure release.

2. Check Coolant Level

Open the coolant reservoir cap slowly to release any pressure.
Inspect the coolant level:
- If the coolant is below the minimum mark, proceed to the next step.

3. Top Off Coolant

Place the funnel into the opening of the coolant reservoir.
Slowly pour the recommended coolant into the reservoir until it reaches the maximum level mark.
Avoid overfilling, as this can cause overflow when the engine heats up.

4. Secure the Cap

Remove the funnel carefully.
Wipe any spills with a clean cloth.
Replace and securely tighten the coolant reservoir cap to prevent leaks.

5. Final Checks

Start the engine and let it run for a few minutes while monitoring the coolant reservoir for any leaks.
Check the dashboard for any warning lights indicating coolant issues.
