Diagnostic Steps

1
Ensure the vehicle is parked on a level surface and the engine is cold.
2
Open the hood and locate the coolant reservoir, typically a translucent plastic tank near the engine.
3
Inspect the coolant reservoir for minimum and maximum level markings.
4

5

Solution

1. Preparation

Gather necessary tools: a flashlight (if needed for visibility), and a clean funnel for refilling.
Ensure that the engine is completely cool to avoid burns.

2. Check Coolant Level

Locate the coolant reservoir on the engine bay.
Inspect the reservoir's side for the markings indicating the minimum and maximum levels.
If the coolant is below the minimum mark, proceed to the next step to add coolant.

3. Adding Coolant

Remove the cap from the coolant reservoir carefully (use a cloth if needed, as it might be hot).
Using a funnel, add the appropriate coolant mixture (typically a 50/50 mix of antifreeze and distilled water) until it reaches the maximum level.
Replace the cap securely after filling.

4. Inspect for Leaks

After adding coolant, inspect all hoses connected to the radiator and the reservoir for any signs of leaks or damage.
Check the area around the engine for any pooled coolant.
