If you change the engine oil and filter
yourself, your Volvo retailer can assist you
in disposing of the used oil. Engine oil can
be harmful to your skin - gloves should
worn when performing this work.

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. Oils with a different quality
rating may not provide adequate engine
protection.

Viscosity (stable ambient
temperatures):




Do not use oils with other viscosity ratings. The
use of incorrect viscosity oil can shorten engine
life.
Volvo recommends the use of energy-conserving
oils. Look for the API label. 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


Changing oil and oil filter

Oil and oil filter changes should be made as
specified in the following table:

If driving conditions
include: Then the correct oil/oil
filter change interval
is:
l Extended periods of
idling and/or low-
speeds operation
l Frequent short trips
(less than 7 miles = 11
km)
l Extended periods of
driving in dusty and/or
sandy areas
l Trailer towing
l Driving in
mountainous areas EVERY 6 MONTHS
OR EVERY
5,000 miles= 8,000 km
WHICHEVER

l Primarily highway
driving
l Frequent trips of
longer than 7 miles =
11 km EVERY 12 MONTHS
OR EVERY
10,000 miles = 16,000

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
