BMW vehicles require specific coolants to maintain optimal engine performance and prevent damage to the cooling system. BMW approved coolant is a mixture of water and a concentrated ethylene glycol-based antifreeze. The exact composition of the coolant may vary depending on the model and year of the BMW, but it should meet BMW's specifications.
BMW Coolant Types
There are two main types of BMW coolant:
* BMW Blue Coolant (BMW Coolant BSS 8119.0): This is the recommended coolant for most BMW vehicles. It is a blue-colored liquid that provides freeze protection down to -40°F (-40°C) and boil protection up to 265°F (129°C).
* BMW Pink Coolant (BMW Coolant BSS 8126.0): This coolant is used in some BMW M vehicles and other high-performance models. It is a pink-colored liquid that provides freeze protection down to -54°F (-48°C) and boil protection up to 275°F (135°C).
Mixing BMW Coolant
BMW coolant must be mixed with water in a specific ratio. The ratio of coolant to water will vary depending on the model and year of the BMW, but it is typically 50/50 or 60/40 coolant to water.
It is important to use distilled water when mixing BMW coolant. Tap water can contain minerals that can damage the cooling system.
Changing BMW Coolant
BMW coolant should be changed every 2 years or 30,000 miles, whichever comes first. The coolant level should also be checked regularly and topped off as needed.
To change the BMW coolant, follow these steps:
1. Park the car on a level surface and allow the engine to cool down.
2. Open the coolant expansion tank.
3. Drain the coolant from the radiator and engine block.
4. Close the coolant expansion tank and fill it with the recommended amount of BMW coolant mixed with water.
5. Start the engine and let it run for a few minutes to circulate the coolant.
6. Check the coolant level and top it off as needed.
Note: It is important to properly dispose of old BMW coolant. Pour it into a container and take it to a recycling center. Do not pour it down the drain or onto the ground.
