Check the belt regularly to make sure it is in good condition and is cle\
an. A worn or dirty belt can cause
poor cooling and low alternator output as well as impair the operation o\
f the power steering and the air
conditioning unit.
NOTE: The drive belt is equipped with a self-tensioning mechanism and require\
s no adjustment
between changes.
WARNING!
The engine must not be running when this check is
performed.
Check coolant level
The cooling system must be filled with coolant and not leak to operate a\
t 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 eng\
ine is new or when the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Fre\
quent removal may prevent
coolant circulation between the engine and the expansion tank during eng\
ine warm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and an\
tifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/ 50 mix of wat\
er and antifreeze). CAUTION!
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle
cools.

Engine oil
Oil specifications
Engine oil must meet the minimum ILSAC specification GF-3, API SL, and A\
CEA A1/ B1. Lower
quality oils may not offer the same fuel economy, engine performance, or\
engine protection.
Volvo recommends
.
Depending on your driving habits, premium or synthetic oils may provide \
superior fuel economy and
engine protection. Consult your Volvo retailer for recommendations on pr\
emium or synthetic oils.
Oil additives must not be used.
NOTE: Synthetic oil is not used when the oil is changed at the normal mainten\
ance services. This oil is
only used at customer request, at additional charge. Please consult your\
Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 86° F (30° C) in your area, Volvo recom\
mends, for the protection of your
engine, that you use a heavier weight oil, such as such as SAE 5W-40 or \
0W-40. See the viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86° F
(30° C), SAE 5W-30 will provide good fuel economy and engine protec\
tion. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 0W-30 or 0W-40 and 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, and for prolonged driving in mountainous areas.

American Petroleum Institute (API) symbol
The API Service Symbol "donut" is divided into three parts:
l The upper section describes the oil's performance level.
l The center identifies the oil's viscosity.
l The lower section indicates whether the oil has demonstrated energy-cons\
erving properties in a
standard test in comparison to a reference oil.

Engine oil
Changing engine oil and oil filter
See the previous page for oil specifications and
page 212 for oil volumes. Refer to the Warranty and
Service Records Information booklet for information on the oil change in\
tervals.
NOTE:
l Volvo does not recommend the use of oil additives.
l Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner
request and at additional charge. Please consult your Volvo retailer.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This\
is especially important during
the period up to the first scheduled maintenance service.
l The vehicle should be parked on a level surface when the oil is checked.\
l If the engine is warm, wait for at least 10-15 minutes after the engine has been switched off\
before
checking the oil.

Checking the oil
- Pull out the dipstick and wipe it with a lint-free rag.
- Reinsert the dipstick, pull it out, and check the oil level.
- Add oil if necessary. If the level is close to the MIN mark, add appro\
ximately 1 US quart (1 liter) of oil.
- Run the engine until it reaches normal operating temperature.
- Switch off the engine and wait for at least 10-15 minutes and recheck \
the oil level. If necessary, add oil
until the level is near the mark.
CAUTION!
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Never fill oil above the MAX mark. This could cause an increase in oil\
consumption.
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Always add oil of the same type and viscosity as already used.

Fluids
Washer fluid reservoir
The washer fluid reservoir is located in the engine compartment and hold\
s approx. 6.8 US qts (6.5 liters).
When there is less than approximately 1 US qt (1 liter) remaining in t\
he reservoir, the washer fluid spray
will be directed to the windshield only.
During cold weather, the reservoir should be filled with windshield wash\
er solvent containing antifreeze.
