Chapter 8 - (cont.)Engine oil
pg. 108
Checking the oil level

The oil level should be checked every
time the car is refuelled. This is
especially important during the engine
break-in period (up to the first service).

CAUTION: Not checking the oil level
regularly can result in serious engine
damage if the oil becomes too low.


Be sure the oil level is maintained between
the upper and lower marks on the dipstick.
Low oil level can cause internal damage to
the engine and over-filling can result in
high oil consumption. The distance
between the dipstick marks represents
approx. 1 US qt (1 liter) of oil. Before
checking the oil level after the car has been
driven, park the car on a level surface and
wait at least 5 minutes after the engine has
been switched off. The oil level should be
halfway between the MIN and MAX
marks.
If the oil is checked before the car is driven
(engine completely cold) the oil level
should be at the MAX mark.

NOTE: The engine must be stopped when
checking the oil.

Draining the oil

Drain the oil after driving while it is still
warm.

WARNING! The oil may be very
hot.
To add or change engine oil

Add oil of the same kind as already used.
Capacity (including filter): 5.9 US qts = 5.75 liters

Changing oil filter



Replace the oil filter at every oil change



WARNING! Oil spilled on a hot exhaust pipe
constitutes a fire risk.

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.
American Petroleum Institute
(API) labels. These labels certify
the oil conforms to the applicable
standards and specifications of
the API.
Servicing pg. 110
Torque exhaust and
intake manifold nuts


A loose manifold could alter air/
fuel ratio and cause an increase
in emissions and/or poor
driveability.

Air cleaner

Replace the air cleaner cartridge
with a new one every 30,000
miles (48,000 km). The
cartridge should be replaced
more often when driving under
dirty and dusty conditions, The
filter cannot be cleaned and,
therefore, should always be
replaced with a new one.

Vacuum fittings, hoses
and connections


Unstable idle, misfiring, or poor
emission control is often caused
by leaking vacuum hoses or
connections. Check hoses and
connections on distributor
vacuum unit, connections on
heater control servo systems and
hydraulic brake servo.
Fuel system cap, tank
and lines, and
connections


The effectiveness of the fuel
system to contain hydrocarbons
is dependent largely on a
leakfree system. Check for
proper sealing of gasoline filler
cap which contains "O" ring-
type seals. Check all
evaporative hoses in vehicle for
tightness. Check fuel lines under
vehicle and repair if necessary.

Fuel (line) filter

The fuel line filter is located
next to the fuel pump. This filter
should be replaced every
100,000 miles (160,000 km).
The filter is replaced as one
complete unit.
Replace more frequently if
contaminated fuel is introduced
into the tank (or if there is
reason to suspect that this has
occurred).

Timing belt

WARNING!
The distributor ignition
system operates at very high
voltages. Special safety
precautions must be followed
to prevent injury.
Always turn the ignition off
when:
l Replacing distributor
ignition components e.g.
plugs, coil, etc.
l Do not touch any part of
the distributor ignition system
while the engine is running.
This may result in unintended
movements and body injury.


Replacing spark plugs

The spark plugs should be
changed every 30,000 miles
(48,000 km). However, city
driving or fast highway driving
may necessitate changing after
15,000 miles (24,000 km) of
driving. When installing new
plugs, be sure to fit the right type

Idle air control system

Your Volvo is equipped with an
electronically-controlled idle air
control system that requires no
checking or adjustment.
Volvo recommends that the
timing belt be replaced every
70,000 miles (112,000 km).

PCV system

The orifice nipple in the intake
manifold and the filter at the
end of the PCV hose in the
aircleaner should be inspected
every 60,000 miles (96,000 km).
Check/replace rubber hoses at
the same time.
and use correct torque, see
Specifications. When changing
the plugs, check that the
suppressor connectors are in
good condition. Cracked or
damaged connectors should be
replaced.
When changing the spark plugs,
clean the terminals and the
rubber seals.
Battery maintenance pg. 111
Battery maintenance

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:
l Check the fluid level in the battery every 6
months or every 10,000 * miles (16,000 km).
The fluid level in each battery cell should be
checked - use a screw driver to open the caps and
a flashlight to inspect the level.
*More frequently in warm climates.
l If necessary, add distilled water to
approximately 0.4 in. (10 mm) above the plates in
the cell or to the level indicator. See the
illustrations above.
l Check that the battery cables are correctly
connected and properly tightened.
l Never disconnect the battery when the engine is
running, for example when changing the battery.
l The battery should be disconnected when a
boost charger is used.
l Switch off the radio before disconnecting the
battery. If your radio has an antitheft code and the
battery is disconnected, the radio code has to be
reentered in order for the radio to function.

Check, without removing the cap, that the level is above
the "MIN" mark of the fluid reservoir.
Always entrust brake fluid changing to an authorized
Volvo retailer.
Drive belt pg. 117
Belt check

Check 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 generator output as well as impair the
operation of the power steering and the air conditioning
unit.

WARNING! The engine must not be running when
this check is performed. NOTE: The belt is equipped with a self-questioning
mechanism and requires no adjustment between changes.
Cooling system pg. 118



Changing coolant

Normally, the coolant does not
need to be changed. If the system
must be drained, use the following
procedure:
Remove the expansion tank cap.
Open the drain cock on the right
side of the engine block and
disconnect the lower radiator
hose.
Fill coolant through the expansion
tank. The heater controls should
be fully open when draining and
WARNING: If the engine is
warm and you are going to top
up coolant, unscrew the cap
slowly in order to allow any
excess pressure to escape.


NOTE: Do not top up with water
only. Water by itself reduces the
rust-protective and anti-freeze
qualities of the coolant and has a
lower boiling point. It can also
cause damage to the cooling system
if it should freeze.

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.
Capacity: See "Specifications"
coolant: Volvo Genuine Coolant/
Antifreeze only

CAUTION
The cooling system must
always be kept filled to 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 anti-freeze/
coolant may not be mixed.
Adjusting washer nozzles, Washer fluid reservoir pg. 119


Adjusting washer nozzles

The washer jets should spray the windshield as shown. Use
the edge of a small screwdriver to adjust the nozzles, if
necessary. Please use caution to avoid damaging the
paintwork.


Washer fluid reservoir

The washer fluid reservoir is located in the engine
compartments and holds approx. 0.5 US gal. (2 liters) -
sedans and 0.8 US gal (3.2 liters) - wagons. During cold
weather, the reservoir should be filled with windshield
washer solvent containing anti-freeze.
