Solution

1. Preparation

Gather tools required for checking and filling coolant, such as a funnel and a clean cloth.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect the Coolant Level

Locate the coolant expansion tank under the hood.
Check the coolant level against the minimum and maximum marks on the tank.
- If the level is below the minimum mark, proceed to the next step.

3. Adding Coolant

If the level is low, carefully remove the cap from the coolant expansion tank.
- Tools Required: Funnel
- Safety Warning: Never open the coolant cap when the engine is hot; allow the engine to cool completely.
Using the funnel, add the appropriate coolant mixture (typically a 50/50 mix of BMW-approved coolant and distilled water) until the level reaches the maximum mark.
Replace the cap securely after filling.

4. Inspect for Leaks

After adding coolant, start the engine and let it run for a few minutes.
Check for any leaks around the coolant hoses and the expansion tank.
