COOLANT

Do not add coolant to the cooling
system when the engine is hot.

Escaping coolant can cause burns.
To avoid the possibility of damage later on,
never use anything other than factory-
approved, nitrite and amino-free extended-
duty antifreeze with corrosion inhibitor.
Every MINI center is aware of these.
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.
Extended-duty antifreeze with corrosion
inhibitor contains the flammable
substance ethylene-glycol. For this reason,
do not spill extended-duty antifreeze with
corrosion inhibitor on hot engine parts. It
could catch fire and cause serious burns.

Comply with the applicable environ-
mental laws regulating the disposal

of extended-duty antifreeze with corrosion
inhibitor.

The illustration shows an example of the

coolant tank on the MINI COOPER.

Checking coolant level

Correct coolant level for cold engine
(approx. 68 7/20 6):

Up to the mark "MAX" 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 instrument cluster must
be no higher than in the first quarter,
otherwise there is a danger of scalding.

To add coolant

MINI COOPER:

1. Slowly open the cap by turning it with

the tab to allow accumulated pressure
toescape.

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

until the correct level is reached – do not
overfill.

The coolant consists of water and
extended-duty antifreeze with corrosion
inhibitor. The mixing ratio of 50 to 50 must
be maintained all the year round due to the
required corrosion resistance. No other
additives are required.

Replace the coolant every 4 years.
