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.

Check coolant level
The cooling system must be filled with
coolant and not leak to operate at maximum
efficiency. Check the coolant level regularly.
The level should be between the "Max" and
"Min" marks on the expansion tank. The
check should be made with particular
thoroughness when the engine is new or
when the cooling system has been drained.
Do not remove the filler cap other than for
topping-up with coolant. Frequent removal
may prevent coolant circulations between the
engine tank during engine warm-up and
cooling.
filling.
Add coolant until the level is up to
the MAX mark or slightly above.
Start the engine and run until hot.
Check the cooling system
connections for tightness. Also re-
check the coolant level.
Capacity: See "Specifications"
coolant: Volvo Genuine Coolant/
Antifreeze only
CAUTION
The cooling system must
always be kept filled to correct
level.
If it is not kept filled, there can
be high local temperatures in
the engine which could result
in damage.
Different types of anti-freeze/
coolant may not be mixed.
