As a proud BMW owner, you understand the importance of maintaining your luxury vehicle's performance and longevity. One critical aspect of BMW maintenance is ensuring the cooling system works optimally. The engine's cooling system relies on the right coolant to regulate the engine temperature and protect it from overheating. In this blog, brought to you by Car Removals Adelaide, we'll explore the types of coolants suitable for BMWs and guide you on how to top it up effectively.

Types of Coolants for BMWs

BMW Coolant (OEM Coolant)

BMW recommends using their proprietary coolant specifically designed for their vehicles. It's a high-quality, ethylene glycol-based formula with additives that provide superior protection against corrosion, cavitation, and scaling. When purchasing this coolant, always ensure it meets BMW's specifications for your particular model.

Ethylene Glycol-based Coolants

If you're unable to find BMW coolant or looking for more budget-friendly options, you can choose ethylene glycol-based coolants from reputable brands. Look for coolants that meet the requirements of ASTM D3306 and ASTM D4985 standards. These coolants are suitable for BMWs and provide adequate protection.

Hybrid Organic Acid Technology (HOAT) Coolants

HOAT coolants are a blend of ethylene glycol and organic acids, making them suitable for modern BMWs. They offer enhanced corrosion protection and a longer service life compared to conventional green coolants. Ensure the HOAT coolant you choose meets the necessary ASTM and BMW specifications.

How to Top Up the Coolant in Your BMW

Before starting, make sure the engine is cool to avoid any burns or injuries. Here's a step-by-step guide on how to top up your BMW's coolant:

Step 1: Open the Hood

Locate the hood release lever inside the car and open the hood. Secure the hood with the provided prop rod.

Step 2: Locate the Coolant Reservoir

Once the hood is open, find the coolant reservoir. It's usually a transparent plastic container located near the engine bay with "COOLANT" written on the cap.

Step 3: Check the Coolant Level

Inspect the coolant level in the reservoir. There are usually "MIN" and "MAX" markings on the side of the container. If the level is below the "MIN" mark or visibly low, proceed to the next step.

Step 4: Prepare the Coolant

If you have the correct coolant, make sure it's properly mixed with water as per the manufacturer's recommendations. Refer to the coolant container for the correct mixing ratio.

Step 5: Top Up the Coolant

Carefully unscrew the coolant reservoir cap (only when the engine is cool) and pour the prepared coolant mixture into the reservoir until it reaches the "MAX" mark.

Step 6: Secure the Cap and Check for Leaks

Tightly screw the coolant reservoir cap back on. Inspect the area around the coolant reservoir for any signs of leaks.

Step 7: Close the Hood

Gently lower the hood and ensure it is securely latched.

Conclusion

Properly maintaining your BMW's cooling system is vital for its performance and longevity. By using the right coolant and topping it up correctly, you can safeguard your engine from overheating and potential damage. Remember always to use BMW-recommended coolants or ethylene glycol-based alternatives that meet the necessary specifications. By following the steps outlined above, you can confidently top up your BMW's coolant and enjoy smooth and trouble-free drives for years to come.
