How to Add Coolant to a BMW F31

Coolant loss in your BMW F31? Don’t panic! Adding coolant is a simple process you can do yourself with a little know-how. In this article, we will explain step by step how to correctly add coolant to your BMW F31 and what you need to pay attention to. From the right coolant type to bleeding the system – here you will find all the important information.

Why is Adding Coolant Important?

A sufficient coolant level is crucial for the lifespan of your engine. Coolant prevents overheating and protects against costly damage. If the coolant level is too low, the engine can overheat and, in the worst case, cause engine damage. Therefore, regularly checking and, if necessary, adding coolant is essential.

The Right Coolant Type for Your BMW F31

Before adding coolant, you must identify the correct coolant type for your BMW F31. Never use the wrong coolant, as this can lead to corrosion and other problems. You can find the recommended coolant specification in your vehicle’s manual. Generally, it is a silicate-based coolant specifically developed for BMW engines.

“Using the wrong coolant can have catastrophic consequences,” warns Dr. Klaus Müller, author of “Modern Vehicle Cooling.”

Step-by-Step Guide to Adding Coolant

Ensure the engine is cold before starting the process. A hot engine and cooling system are under pressure and can cause burns.
Open the hood and locate the coolant reservoir.
Check the coolant level. The reservoir usually has “Minimum” and “Maximum” markings.
Carefully open the cap of the coolant reservoir.
Slowly and carefully add the correct coolant until the level is between the “Minimum” and “Maximum” markings.
Close the cap of the coolant reservoir tightly again.
Start the engine and let it run for a few minutes.
Check the coolant level again and refill if necessary.

Bleeding the Cooling System

After adding coolant, it is important to bleed the cooling system to remove air bubbles. You can find the exact procedure for bleeding the cooling system in your BMW F31 manual.

“Air in the cooling system can impair cooling performance,” explains engineer Sarah Schmidt in her book “Car Repair for Beginners.”

When Should You Visit a Workshop?

If you are unsure or frequently need to add coolant, you should visit a workshop. Constant coolant loss can indicate a leak in the cooling system.
