Belt checkCheck 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 alternator out-
put as well as impair the operation of the power
steering and the air conditioning unit.
NOTE
The drive belt is equipped with a self-ten-
sioning mechanism and requires no adjust-
ment between changes.
WARNING
The engine must not be running when this
check is performed.Check coolant levelThe 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 top-
ping up with coolant. Frequent removal may
prevent coolant circulation between the engineand the expansion tank during engine warm up
and cooling.
Changing coolantNormally, the coolant does not need to be
changed. If the system must be drained, con-
sult a trained and qualified Volvo service tech-
nician.
Do not top off with water only. This reduces the
rust-protective and antifreeze qualities of the
coolant and has a lower boiling point. It can
also cause damage to the cooling system if it
should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water
and antifreeze.
CAUTION
The cooling system must always be kept
filled to the correct level. If it is not kept filled,
there can be high local temperatures in the
engine which could result in damage. Dif-
ferent types of antifreeze/coolant may not
be mixed.
WARNING
Never remove the radiator cap while the
engine is warm. Wait until the vehicle cools.

AThe transmission oil does not normally need to be changed during the service life of the vehicle. However, it may be necessary to replace the oil if the vehicle is often driven in areas of sustained
temperature extremes (hot or cold), when towing a trailer over long distances, for prolonged driving in mountainous areas, or if the vehicle is often driven short distances in temperatures under 40 °F
(5 °C).BSee page 90 for volumes
