Diagnostic Steps

1
Ensure the vehicle is parked on a level surface and the engine is turned off.
2
Open the hood and locate the coolant reservoir—typically a translucent plastic tank with a cap.
3
Inspect the coolant level against the markings on the side of the reservoir (minimum and maximum levels).
4
Check for any signs of coolant discoloration or contamination.
5

Solution

1. Preparation

Gather necessary tools: a clean cloth or paper towel for handling the cap.
Ensure the engine is cool to avoid burns from hot coolant.

2. Locate Coolant Reservoir

Open the hood and secure it with the hood prop.
Identify the coolant reservoir, which is usually on the left side of the engine bay, marked with a coolant symbol on the cap.

3. Inspect Coolant Level

Look at the side of the reservoir to find the minimum (MIN) and maximum (MAX) level indicators.
If the coolant is below the MIN mark, prepare to add coolant.

4. Add Coolant (if necessary)

If the level is low, remove the cap by turning it counterclockwise—use a cloth to protect your hand if the cap is hot.
Pour the appropriate coolant (usually a 50/50 mix of water and antifreeze suitable for VW vehicles) into the reservoir until it reaches the MAX mark.
Replace the cap securely by turning it clockwise.
