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. Mixing BMW coolant with distilled water keeps other unwanted minerals present in tap water from forming deposits in the engine. It's properly formulated for use in your car and the metals in your engine are selected for BMW formula coolant in the engine. The use of Original BMW Anti-Freeze/Coolant will ensure sufficient cooling in summer and protection against freeze-ups in winter. I'm not sure why this is so hard to understand.

(Keep a paper towel handy to soak up the coolant coming out of the bleed screw).ģ8) Once the reservoir (system) is full (it will take almost two gallons of antifreeze) fully close the reservoir cap." Keep filling until the bleed screw is passing coolant with no bubbles in it.

The bleed screw will bleed air as it gets trapped in the reservoir. My question then was, will any coolant do, or do I need special BMW coolant.įrom the DIY for water pump replacement on the N52:ģ3) Reinstall the blue radiator drain screw.ģ4) If you didn’t open the bleed screw on the coolant reservoir, open it now (about 4 turns)ģ5) Slowly fill the system with a premixed 50/50% mix of BMW coolant and distilled water.ģ6)ğill the reservoir all the way up to the bottom of the filler neck. 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.
