Engine compartment overview

This overview shows some service-related com-
ponents.

The layout of the engine compartment may vary depend-
ing on model and engine variant.

Coolant expansion tank

Brake fluid reservoir (located on the driver's
side)
Washer fluid filler pipe

Fusebox

Air filter

Engine oil filler pipe

WARNING

Bear in mind that the cooling fan (located at

the front of the engine compartment behind

the radiator) may start or continue running

automatically up to about 6 minutes after the

engine is turned off.
Always entrust engine washing to a workshop

– an authorized Volvo workshop is recom-

mended. If the engine is hot, there is a risk of

fire.

WARNING

The ignition system works with extremely high

and dangerous voltages. The vehicle electrical

system should always be in ignition mode 0

when work in being performed in the engine

compartment.
Do not touch any spark plugs or ignition coils

when the vehicle electrical system is in igni-

tion mode II or when the engine is warm.

Engine oil

For the recommended service intervals and war-
ranties to be applied, an approved engine oil
must be used.

Volvo recommends:

Fill the washer fluid at regular intervals, e.g. when refueling.

MAINTENANCE AND SERVICE

}}

577

If the engine oil is not checked regularly and the
level becomes low, this could cause serious
engine damage.

CAUTION

To satisfy the requirements for the engine's
service intervals, all engines are factory-filled
with a specially adapted synthetic engine oil.
Great care has been put into the choice of oil,
with consideration given to service life, starta-
bility, fuel consumption and environmental
impact.

For the recommended service intervals to
apply, an approved engine oil must be used.
Only use the prescribed oil grade to top off or
change the oil. Otherwise, there is a risk of
the vehicle's service life, startability, fuel con-
sumption and environmental impact being
affected.

Failure to use engine oil of the prescribed
grade and viscosity could cause damage to
engine-related components. Volvo Car Corpo-
ration disclaims warranty liability for such type
of damage.

Volvo recommends entrusting oil changes to
an authorized Volvo workshop.

Volvo uses different systems to warn if the oil
level is too low/high or the oil pressure is low. On
engine variants with an oil pressure sensor, a

warning symbol is displayed in the instrument
panel when oil pressure is low

. On engine

variants with an oil level sensor, the

warn-

ing symbol in the instrument panel and display
messages are used to alert the driver. Some
engine variants have both systems. Contact a
Volvo retailer for more information.

Change the engine oil and oil filter according to
the schedule specified in the Warranty and Main-
tenance Records Information booklet. Oils of a
higher grade than that specified may be used. If
the vehicle is driven in adverse conditions, Volvo
recommends using an oil with a higher grade
than that specified.

Checking and filling engine oil

The engine oil level is monitored by an electronic
oil level sensor.

MAINTENANCE AND SERVICE

578

Filler pipe

It may be necessary to top up engine oil between
regularly scheduled services.

No action is necessary with regard to engine oil
level until a message appears in the instrument
panel.

WARNING

If this symbol is shown together

with the message

Engine oil level

Service required

, visit a workshop

– an authorized Volvo workshop is

recommended. The oil level may be too high.

CAUTION

If this symbol is shown together
with a message about low oil level,
for example

Engine oil level low

Refill 1 liter

, fill only with the indi-

cated volume, e.g. 1 liter (1 quart).

WARNING

Do not spill oil on the hot exhaust pipes as

this could cause a fire.

Viewing oil level in the center display

The oil level can be viewed using the electronic
oil level gauge in the center display once the
vehicle has been started. The oil level should be
checked regularly.

1. Open the

Car Status

app from App view in

the center display.

2. Tap

Status

to display the oil level.

Oil level graphic in the center display.

NOTE

The system cannot directly detect changes
when the oil is filled or drained. The vehicle
must have been driven approximately 30 km
(20 miles) and have been stationary
5 minutes on a level surface and with the
engine off before the correct oil level will be
displayed.

Engines with an electronic oil level sensor do not have a dipstick.

MAINTENANCE AND SERVICE

}}

579

NOTE

If the conditions for measuring oil level are
not properly fulfilled (time after engine shut-
down, vehicle inclination, ambient tempera-
ture, etc.) the message

No value available

will be shown in the center display. This does
not mean that anything is wrong in the vehi-
cle systems.

Refilling coolant

Coolant helps keep the combustion engine at
the right operating temperature. The heat trans-
ferred from the engine to the coolant can be
used to warm the passenger compartment.

When refilling coolant, follow the instructions on
the package. Never fill the cooling system with
only water. The risk of freezing is increased with
too low or too high amounts of coolant.

If there is coolant under the vehicle, smoke from
the cooling system, or if more than 2 liters (about
2 quarts) of coolant has been added to the sys-
tem, there could be something wrong with the
cooling system and starting the vehicle could
damage the engine. Call a tow truck and do not
attempt to start the engine.

WARNING

The coolant may be very hot. Never unscrew

the cap when the coolant is hot. If coolant

must be filled, unscrew the expansion tank

cap slowly to relieve overpressure.

Coolant expansion tank, left-hand drive vehicle.

MAINTENANCE AND SERVICE

580

Unscrew the cover in the plastic covering.

Unscrew the expansion tank cap and fill
coolant as needed. The level should not
exceed the yellow MAX mark inside the
expansion tank.

Put the components back in place in the reverse
order.

CAUTION

•

Do not ingest the contents. May cause
damage to organs (kidneys).

•

Use premixed coolant according to Vol-
vo's recommendations. If concentrated
coolant is used, make sure that the cool-
ant mixture is 50% coolant and 50%
water of acceptable quality.

•

Do not mix different types of coolant.

•

To help ensure sufficient corrosion pro-
tection in the system, only use new cool-
ant when replacing larger components in
the cooling system.

•

Never run the engine unless the cooling
system is properly filled. An improperly
filled cooling system could lead to high
temperatures and cracks in the cylinder
heads.

•

High levels of chlorine, chlorides and
other salts may cause corrosion in the
cooling system.
