What coolant and how much needed? (N52)
I'm going to change out my waterpump and thermostat housing in the next few days, and can't seem to find what kind of coolant I need, and how much of it.
Anyone? |

Search the forum next time you'll get all the answers you need. Read the DIYs; they are very clear on the procedure and the type and amount of coolant needed. |

I missed the bit where it said, in the DYI I searched for and found, that I needed to mix a gallon of BMW coolant and a gallon of distilled water.
Perhaps I'm looking at a different DIY. My question then was, will any coolant do, or do I need special BMW coolant. |

"Coolant Refill procedure: 33) Reinstall the blue radiator drain screw. 34) If you didn’t open the bleed screw on the coolant reservoir, open it now (about 4 turns) 35) Slowly fill the system with a premixed 50/50% mix of BMW coolant and distilled water. 36) Fill the reservoir all the way up to the bottom of the filler neck. The bleed screw will bleed air as it gets trapped in the reservoir. Keep filling until the bleed screw is passing coolant with no bubbles in it. (Keep a paper towel handy to soak up the coolant coming out of the bleed screw). 37) Close the bleed screw. 38) Once the reservoir (system) is full (it will take almost two gallons of antifreeze) fully close the reservoir cap." I'm not sure why this is so hard to understand. Just use BMW coolant. It's properly formulated for use in your car and the metals in your engine are selected for BMW formula coolant in the engine. Mixing BMW coolant with distilled water keeps other unwanted minerals present in tap water from forming deposits in the engine. Use of some other coolants with different formulations are not recommended by BMW and may be harmful to the long-term operation of the cooling system. It's not like BMW prices their coolant at twice the price of other brands, so just use it and you know the coorect coolant is in the system. Simple.

You don't HAVE to use BMW coolant. It is not magical coolant. The most important part is to make sure you follow the venting procedure, which is a simple process. Do a search on here. I believe eninty has a DIY on here. How I do it is to remove the undercover, remove one of the blue screws to the radiator, refill, vent, refill, and vent (not a typo; when you vent you will need to add more coolant. Eninty has you remove the waterpump hose(s) which can be a PITA. It is the correct thing to do, but I skip that.

G-48 has plastic compatibility specs which are different from some otherwise very similar coolants. |

I don't think you'll have to worry about anything at that change interval. I opted for G-05 for the E92, but have used similar extended life products in our older BMW. Neglect is what harms cooling systems, not coolant.
