Brake Fluid; Checking Coolant Level - BMW 525i Owner's Manual

Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of water and the addition of
antifreeze and anticorrosion agent. Not all com-
mercially available additives are suitable for
your BMW. Ask your BMW center for suitable
additives.
Only use suitable additives, as otherwise
engine damage may result. The additives
present a health hazard; observe the instruc-
tions on the containers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<

Checking coolant level

1. The engine must be at ambient tempera-
ture.
2. Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3. The coolant level is correct when the cool-
ant level is between the MIN and MAX
marks, refer to the diagram adjacent to the
filler neck.
4. If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5. Turn the cap until there is an audible click.
6. Have the reason for the coolant loss elimi-
nated as soon as possible.

assess the suitability of other brake pads for
use on your vehicle, we are unable to assume
continued responsibility for the vehicle's oper-
ating safety if non-approved pads are
installed.<
