Solution

1. Preparation

Gather tools: gloves, clean funnel, and a flashlight.
Ensure the vehicle is parked on a level surface.

2. Check Coolant Level

Open the hood and secure it with the prop rod.
Locate the coolant reservoir cap (typically labeled with a coolant symbol).
Inspect the reservoir for the level of coolant; ensure it is visible through the side of the container.
If the coolant is low, remove the cap slowly to avoid pressure release.
Use a clean funnel to add the appropriate type of coolant (check owner's manual for specifications).

3. Inspect for Leaks

After adding coolant, visually check hoses and the reservoir for any signs of leaks.
Look under the vehicle for any puddles of coolant.
Check the radiator for cracks or loose connections.

4. Cap and Clean Up

Securely replace the coolant reservoir cap.
Wipe up any spills with a clean cloth.
Close the hood securely.
