G8X BMW M2 M3 M4 Coolant / Antifreeze (2021+)

BMW offers coolant in blue and green. Most 2021+ M2, M3 and M4 models (aka G80 G81 G82 G83 G87) will have the green coolant, but it is still possible it came from the factory with blue. BMW does not recommend mixing the coolants, so visually confirm if your coolant is blue or green!
