Check, without removing the cap, that the level is above
the "MIN" mark of the fluid reservoir.
Always entrust brake fluid changing to an authorized
Volvo retailer.
Drive belt pg. 117
Belt check
Check the belt regularly to make sure it is in good
condition and is clean. A worn or dirty belt can cause poor
cooling and low generator output as well as impair the
operation of the power steering and the air conditioning
unit.
WARNING! The engine must not be running when
this check is performed. NOTE: The belt is equipped with a self-questioning
mechanism and requires no adjustment between changes.
Cooling system pg. 118
Changing coolant
Normally, the coolant does not
need to be changed. If the system
must be drained, use the following
procedure:
Remove the expansion tank cap.
Open the drain cock on the right
side of the engine block and
disconnect the lower radiator
hose.
Fill coolant through the expansion
tank. The heater controls should
be fully open when draining and
WARNING: If the engine is
warm and you are going to top
up coolant, unscrew the cap
slowly in order to allow any
excess pressure to escape.
NOTE: Do not top up with water
only. Water by itself reduces the
rust-protective and anti-freeze
qualities of the coolant and has a
lower boiling point. It can also
cause damage to the cooling system
if it should freeze.

Oil quality
Meeting API specification SG, SG/CD, SH or
Energy Conserving (EC) II
For best fuel economy and engine protection,
consult with your authorized Volvo retailer for
recommended oils. Oil with a different quality
rating may not provide adequate engine
protection.
Synthetic oils complying with oil quality
requirements are recommended for: driving in
areas of sustained temperature extremes (hot or
cold), when towing a trailer over long distances or
for prolonged driving in mountainous areas.
Extra oil additives must not be used unless
advised by an authorized Volvo retailer.
NOTE:SAE 15W/40 should only be used in
extreme operating conditions such as trailer
towing in sustained ambient temperatures over
104° F (40° C). However, SAE 10W-30 synthetic
oil would be a better alternative in such
conditions.
SAE 15W-40 should not be used under normal
operating conditions.

The following should be
checked regularly:
Coolant level should be
between the expansion tank
marks. Mixture: 50% anti-
freeze and 50% water. See
page 118.
Power steering - When
cold, the level must not be
above the COLD mark and
when hot it must not be
above the HOT mark. Top
up if the level drops to the
ADD mark with ATF fluid.
See page 116.
Engine oil - level should be
between the dipstick marks.
The distance between the
marks represents approx. 1
US qts. (1 liter). See page
108.
Brake fluid - check,
without removing the cap,
that the level is above the
MIN mark. Use brake fluid
DOT 4+. See page 116.
Washer fluid - reservoir
should be filled with water
and solvent (wintertime:
windshield washer anti-
freeze). See page 119.
Octane rating, see page 55.
Tire pressure, see label located on
the rear edge of the right front
door.
