Brake Fluid - BMW M COUPE 2002 Owner's Manual

Coolant
112n
Checking coolant level
Correct coolant level when the engine
is cold (approx. +68 7/+20 6).
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck (refer to the arrow in the illustra-
tion), but no more than 0.8 in (2 cm)
above it – that is, up to the second mark
on the float (refer also to the schematic
diagram next to the filler neck).
To add coolant
Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant temper-
ature gauge in the instrument cluster
must be located in the blue field; other-
wise, there is a danger of scalding.
1. Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape, then open
2. If the coolant is low, slowly add
coolant until the correct level is
reached – do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the
prescribed all-season 50 :50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant regularly. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
