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.

The cooling system must

the engine which could result
in damage.
Different types of anti-freeze/
coolant may not be mixed.

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.
