2008 VOLVO S60 engine

The drive belt is equipped with a self -tensioning mechanism and requires 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 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 circulation
between the engine and the expansion tank during engine warm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be drained, consult a trained and qualified Volvo
service technician.
NOTE
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. Different types of antifreeze/coolant may not be mixed.
WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools.

192 09 Maintenance and servicing
Engine oil
Oil specifications
Engine oil must meet the minimum ILSAC specification GF-3, API SL, or ACEA A1/B1. Lower quality oils may not
offer the same fuel economy, engine performance, or engine protection.
Volvo recommends Castrol.
Depending on your driving habits, premium or synthetic oils may provide superior fuel economy and engine protection.
Consult your Volvo retailer or a trained and qualified Volvo service technician for recommendations on premium or
synthetic oils.
ProCarManuals.com

Oil additives must not be used.
NOTE
Synthetic oil is not used when the oil is changed at the normal maintenance services. This oil is only used at customer
request, at additional charge. Please consult a trained and qualified Volvo service technician.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 104° F (40° C) in your area, Volvo recommends, 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 temperatures do not exceed 104° F (40° C), SAE
5W -30 will provide good fuel economy and engine protection. 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.
193 09 Maintenance and servicing
Engine oil
American Petroleum Institute (API) symbol
The API Service Symbol "donut" is divided into three parts:
ProCarManuals.com

The upper section describes the oil's performance level.
The center identifies the oil's viscosity.
The lower section indicates whether the oil has demonstrated energy-conserving properties in a standard test in
comparison to a reference oil.
NOTE
Volvo uses different systems to indicate a low oil level or pressure. Some models have an oil pressure sensor, in which
case a warning symbol (see page 50
) is used to indicate low oil pressure. Other models have an oil level sensor, in
which case the driver is alerted by the warning symbol in the center of the instrument panel and a text in the information
display. Some models use both systems. Contact a trained and qualified Volvo service technician for more information.
Changing engine oil and oil filter
See the previous page for oil specifications and page 246
for oil volumes. Refer to the Warranty and Service Records
Information booklet for information on the oil change intervals.
NOTE
Volvo does not recommend the use of oil additives.
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge. Please consult a trained and qualified Volvo service technician.
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.
The vehicle should be parked on a level surface when the oil is checked.
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
1. Pull out the dipstick and wipe it with a lint-free rag.
2. Reinsert the dipstick, pull it out, and check the oil level.
3. Add oil if necessary. If the level is close to the MIN mark, add approximately 1 US quart (1 liter) of oil.
4. Run the engine until it reaches normal operating temperature.
5. 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.
194 09 Maintenance and servicing
Engine oil
CAUTION
Not checking the oil level regularly can result in serious engine damage 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 damage if the oil level becomes too low.
Always add oil of the same type and viscosity as already used.

WARNING
Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.
195 09 Maintenance and servicing
Fluids
Washer fluid reservoir
The washer fluid reservoir is located in the engine compartment and holds approx. 6.8 US qts (6.4 liters).
During cold weather, the reservoir should be filled with windshield washer solvent containing antifreeze.

WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools.
If it is necessary to top up the coolant when the engine is warm, unscrew the expansion tank cap slowly so that the
overpressure dissipates.

The battery in your vehicle is located under the floor of the trunk.
Driving habits and conditions, climate, the number of starts, etc. all affect the service life and function of the battery. In
order for your battery to perform satisfactorily, keep the following in mind:
Check the fluid level in each cell in the battery every 24 months or every 15,0001 miles (24,000 km), whichever is
sooner. The fluid should be at the level shown in the illustrations above (A)
2. Do not overfill.
1More frequently in warm climates.
Use a screw driver to open the caps or cover and a flashlight to inspect the level.
If necessary, add distilled water. The level should never be above the indicator (A).
The fluid level should be checked if the battery has been recharged.
After inspection, be sure the cap over each battery cell or the cover is securely in place.
Check that the battery cables are correctly connected and properly tightened. Route ventilation hose through opening in
floor (see page 199
)
2The level indicator inside the battery could be designed in various ways. See illustrations.
Never disconnect the battery when the engine is running, for example when changing the battery.
The battery should be disconnected from the vehicle when a battery charger is used directly on the battery.
However, if the battery is being charged via the connecting points in the engine compartment (see page 199), the
battery must be connected.
WARNING
PROPOSITION 65 WARNING!
Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the state of
California to cause cancer and reproductive harm. Wash hands after handling.
WARNING
Never expose the battery to open flame or electric spark.
Do not smoke near the battery.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If
contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
