This is the coolant or anti-freeze that MINI recommends for your MINI. MINI Recommends the coolant system drain and refill EVERY 4 YEARS as listed in the 'Additional Service Items' section of Inspection II. This will maximize longevity of the cooling system and its components.

This Blue coolant is specially formulated with no Phosphates or Nitrites to ensure compatibility with your MINI Cooper and S. The factory recommends replacement every 4 years but many owners like to change more often.

MINI recommends a 50% mix of this coolant and distilled water. Coolant comes in one gallon bottles, may be labelled 'MINI' or 'BMW' depending on supply.

Approximate capacity of cooling systems:

Both Gen 1 and Gen 2 Minis (Rxx)
Cooper - 5.6 quarts
Cooper S - 6.3 quarts

Gen3 Minis  (Fxx)
Cooper with manual transmission - 4.9 liters
Cooper with automatic transmission - 5.7 liters
Cooper S with manual transmission - 5.8 liters
Cooper S with automatic transmission - 6.1 liters

Do not add coolant to the cooling system when the engine is hot. Escaping coolant can cause burns.

See instructions on drain and refill here.

Comply with applicable environmental laws regulating the disposal of coolant additives. Always dispose of used anti-freeze according to local laws and regulations.

Here is an interesting post from a popular MINI forum:

I'm a Master Level ASE tech (plus L1 and X1 cert)., and I teach Automotive Technology at a local Community College. You guys putting in the wrong fluids keep me, and my students who go on to join the tech workforce in business. Let's just say in my time dealing with European cars since '93 I've seen more than a few water pump impellers dissolved, heads fail, rotted intakes, and cooling system woes. It's simply not worth skimping on. I'm not saying you have to march out to the dealer, but you should research who makes the OEM fluids and stick to them. People forget the chemistry in today's cars is as complex as the electronics.
