Coolant is green and need to top it off?
Hi all,
I realized that my coolant level is slightly low, I had a gallon of blue BMW coolant sitting in my garage but I am not sure if I can mix the blue coolant with green ones? I just learned that BMW does not use the blue coolant anymore, it is green only but I already have the blue coolant which was made for BMW. Is it safe to add blue on top of green or do I need to go to the dealer and buy a green one instead? |

BMW HT-12 can be used in any vehicle that currently contains G48 coolant (blue), but G48 should not continue to be used in vehicles that were originally filled with HT-12. (see compatibility image) This HT-12 Antifreeze/Coolant is exclusively formulated and produced for BMW to protect your engine year-round when used as directed. It fulfills the very high standards and requirements set by BMW to help protect the engine against freezing, boil over, corrosion, and excessive silicate gel precipitation. This ethylene glycol-based antifreeze contains no nitrites or phosphate, greatly reducing the possibility of harmful deposit formation. BMW antifreeze provides protection for metals such as cast iron, steel and aluminum. |

The coolant is contained in a sealed system, however. If you are low and need to keep replacing, there is probably a leak somewhere. |

Check around your expansion tank seam. If there’s residue, it’s probably leaking.
I did a DIY a while ago. If done right, can swap it out easily without needing much coolant to top off. |

I just bought this M4 and not sure if it’s loosing coolant or not. It’s little less than full. I just dropped it off at an Indy shop for an oil change. The tech will fill up coolant. I’ll monitor for leaks thank you.
Note: Indy charges $92 for an oil change including top off for coolant |

This! Check your charge cooler because if it’s leaking it’s going straight into the engine.
