COOLANT

Do not add coolant to the cooling sys-
tem when the engine is hot. Escaping

coolant can cause burns.
Antifreeze and anti-corrosion agents are
hazardous to health. Always store these
agents in tightly-closed original containers
kept well away from the reach of children.
Antifreeze and anti-corrosion agents are
flammable. Therefore, do not spill them
over hot engine parts; otherwise they may
ignite and cause burns. Always observe the
instructions for use provided on the con-
tainer.

Comply with the applicable environ-
mental laws regulating the disposal

of antifreeze and anti-corrosion agents.

The illustration shows as an example the
coolant tank on the MINI COOPER.

Checking coolant level

Correct coolant level with cold engine,
approx. 68

7/206:

Up to the MAX mark of the transparent
expansion tank.

Only open the cap of the expansion
tank when the engine has cooled

down. The needle on the coolant tempera-
ture gauge in the display elements must be
no higher than in the first quarter; other-
wise there is a danger of scalding.

To add coolant

MINI COOPER:

1. Slowly open the cap by pulling at the tab

to allow accumulated pressure to escape

2. Pull open the cap completely
3. If the coolant is low, slowly add coolant

until the correct level is reached; do not
overfill.

MINI COOPER S:

1. Open the cap by turning it slightly coun-

terclockwise to allow accumulated pres-
sure to escape

2. Unscrew and open the cap completely
3. If the coolant is low, slowly add coolant

until the correct level is reached; do not
overfill.

The coolant is made up of water and an
antifreeze with corrosion resistance. The
mixture ratio of 50 to 50 must be kept the
entire year due to the required anti-corro-
sion property. No other additives are
required.

Replace the coolant every four years.
