Antifreeze OEM BMW or OEM Toyota

Toyota coolant, the red / pink stuff is some of the best coolant available.

Just use toyota long life coolant je bro. Applicable to all car but buy the original one at toyota SC. Many prefered this coolant since it is good to engine cooling system

I currently just drove 20hrs down south to Florida and the engine level has stayed slightly below half level as it should be the entire trip. Still in Florida driving around the intense heat and sun and everything is still going well.

genuine BLUE BMW coolant (they released a GREEN BMW coolant around 2019 so remember to specify you want BLUE when ordering parts now). I dilute it 50/50 with distilled water (not tap water).

BMW blue only.

BMW only. Not saving yourself any money in the long run being cheap with this particular fluid. It isn\u2019t even that much more expensive than other brands.

OEM stuff from BMW.

Only use bmw brand it has special additives for the electric water pump

You can add distilled water as a temporary option if you can't find Toyota pink coolant.

So you don't mix coolants. BMW coolant uses embedded teflon or something. Dump in the wrong coolant and you have to run (I kid you not) laundry detergent through the entire system several times, flush the shit out of it several times then replace every single rubber hose.
