We suggest using only German OEM BMW engine antifreeze to keep your cooling system working at its best, part number 83192468442 (83 19 2 468 442). BMW only recommends certain coolants because they do not contain nitrites, amines, phosphates, or borates. Off-the-shelf coolant from a local parts chain is unacceptable.
This new green-colored coolant was introduced in 2018 and is used instead of the older blue-colored coolant. Green is backwards compatible with blue and can be used on cars before 2018. However, BMW does not advise using the older blue formula on cars made after January, 2018.
The green coolant includes silicates, which add extra protection for cooling internals but the coolant must be replaced every two years
We recommend mixing a 1:1 ratio with distilled water in street cars for added corrosion resistance, anti-freeze protection, and water pump lubrication. Drivers looking for added cooling properties can reduce the amount of antifreeze in their coolant mix, but should only do this in warmer climate where freezing is not possible (see chart below). If you plan on running less than 1:1 antifreeze to water, we suggest measuring the freezing point of the coolant mix.
If extreme heat may cause engine knocking/pre-ignition you can also mix with Red Line Water Wetter.
