Why Coolant Matters
Coolant, also known as antifreeze, is vital for your car’s health. It prevents the engine from overheating in summer and freezing in winter. Moreover, it protects the engine and cooling system against corrosion and assists in heat transfer.

- Pentosin Antifreeze: Pentofrost NF (G11) is a suitable choice for your BMW. It’s a silicate European concentrate antifreeze that you can find in a 1.5-liter bottle¹.
- Color: BMW typically uses blue or green coolant. The color indicates the type of corrosion inhibitors used in the formula⁵.
How Much Coolant Do You Need?
The 2006 BMW 330i has a cooling system capacity of approximately 7.8-9.3 liters. It’s crucial to check the owner’s manual or consult with a professional to determine the exact amount required for your vehicle⁵.
