Solution

1. Preparation

Gather necessary tools and materials.
Tools required:
- Clean cloth
- Funnel (if adding coolant)
Safety warnings:
- Ensure the engine is cool before opening the coolant reservoir to avoid burns.

2. Inspect Coolant Level

Remove the coolant reservoir cap gently to avoid any residual pressure.
Visually inspect the coolant level. It should be between the MIN and MAX markings.
If the level is below the MIN mark, proceed to add coolant.

3. Adding Coolant

If coolant needs to be added, use a funnel to prevent spills.
Add a 50/50 mixture of BMW-approved coolant and distilled water, ensuring it matches the specifications outlined in the owner’s manual.
Fill until the coolant reaches the MAX mark.

4. Replace Cap and Clean Up

Securely replace the coolant reservoir cap, ensuring it is tightly sealed.
Wipe any spills or excess coolant around the reservoir area to prevent contamination.

5. Dispose of Old Coolant

If any old coolant was removed or spilled, ensure it is disposed of properly according to local regulations.
