MAINTENANCE

Maintenance services

Your Volvo has passed two major inspections before it was delivered to y\
ou, according to Volvo specifications. When driven 600 - 1,200 miles (1,000
2,000 km), your car should be brought to the Volvo dealer for a mainten\
ance service. Engine, manual transmission and rear axle oils, will be changed
at this time.
Following this inspection, maintenance Inspections as outlined In this b\
ook should be performed every 5,000 miles (8,000 km).
Engine oil and oil filter changes should be performed every 5,000 miles \
(8,000) km, or at the time intervals outlined on page 62.
The extended maintenance inspection intervals make it even more advisabl\
e to follow this program.
Inspection and service should also be performed any time a malfunction i\
s observed or suspected.
It is recommended that receipts for vehicle emission services be retaine\
d in the event questions arise concerning maintenance. See your "Warranty
Information and Maintenance Records Booklets".

Maintenance Inspection Intervals

Volvo advises you to follow the inspection program at 5,000 mile or 8,00\
0 km intervals which is outlined in the "Warranties and Maintenance Records
Manual: This maintenance program contains inspections and services neces\
sary for the proper functioning of your car over the next inspection interval.
The maintenance inspections contain several checks which require special\
instruments and tools and therefore must be performed by a qualified
technician.
To keep your Volvo in top condition, specify time tested and proven Genu\
ine Volvo Parts and Accessories.

Unleaded Fuel

Each Volvo has a catalytic converter and must use only unleaded gasoline\
(as specified on the
instrument panel and by a label near the filter inlet). U.S. and Canadi\
an regulations require that pumps
delivering unleaded gasoline be labeled "UNLEADED". Only these pumps hav\
e nozzles which fit your
car's filler inlet. It is unlawful to dispense leaded fuel into a vehicl\
e labelled "unleaded gasoline only".

Leaded gasoline damages the catalytic converter and the oxygen sensor sy\
stem. Repeated use of leaded
gasoline will lessen the effectiveness of the emission control system an\
d could result in loss of emission
warranty coverage. State and local vehicle inspection programs will make\
detection of misfueling easier,
possibly resulting in emission test failure for misfueled vehicles.

Octane Rating

Volvo recommends the use of premium unleaded gasoline with an (R+M)/2 \
rating of 91. This is
generally equivalent to a Research Octane Number (RON) of 95 or higher\
.

Deposit Control Gasolines

Volvo recommends the use of gasolines that contain "Deposit Control" add\
itives. These additives are
specially formulated to prevent the build up of certain injector and int\
ake system deposits. Fuels
containing "Deposit Control" additives are usually advertised as contain\
ing them and may have
additional claims to "clean injectors and intake valves" or similar word\
ing.

25:08 AM

Volvo 1990 240 Model
If it is not clear whether the fuel contains such additives, ask the sta\
tion operator for further information
regarding the detergency of their gasolines.

Gasoline Containing Alcohol

Some fuel suppliers sell gasoline containing alcohol without advertising\
the presence of alcohol. If you
are not sure whether there is alcohol in the gasoline you buy, check wit\
h the service station operator.

Blends of unleaded gasoline and ethanol (ethyl alcohol, grain alcohol)\
, sometimes called "gasohol", are
available in some areas. Gasohol, if used, must contain no more than 10 \
percent ethanol and must have
an (R+M)/2 rating of 87 or higher. If you experience problems with sta\
rting, drive ability, or fuel
economy with gasohol, you should discontinue its use.
Take care not to spill gasoline during refueling. Gasolines containing a\
lcohol can cause damage to
painted surfaces, which may not be covered under the New Vehicle Limited\
Warranty.
Caution:
Do not use gasolines containing methanol (methyl alcohol, wood alcohol)\
. This practice can result in
vehicle performance deterioration and can damage critical parts in the f\
uel system. Such damage may
not be covered under the New Vehicle Warranty.

Fuel Tank

The fuel tank is designed to hold approx. 15.8 US gal. (60 liters), wi\
th sufficient volume left over to
accommodate possible expansion of the fuel in hot weather.
Be aware that the "usable" tank capacity will be somewhat less than the \
15.8-US gal. (60-liter)
maximum. When the fuel level is low, such factors as ambient temperature\
, the fuel's "vapor pressure"
characteristics, and terrain can affect the fuel pumps' ability to suppl\
y the engine with an adequate
supply of fuel. Therefore, it is advisable to refuel as soon as possible\
when the needle nears the red zone.
After the needle enters the red zone, you should be able to drive approx\
. 25 miles (40 km) depending on
driving style and conditions.

Volvo does not recommend oil additives, as they can adversely affect the\
engine.

Changing oil and oil filter

Oil and oil filter are first changed at the 600-1,200 mile (1,000-2,000\
km) service. Thereafter, changes
should be made as specified by this table:

Capacity

Including oil filter: 4.0 US qts = 3.85 litres
Check oil level when filling fuel.
SAE 15W/40 is recommended for use in driving conditions that raise oil t\
emperature and increase oil
consumption (i.e., mountain driving, trailer towing).

Volvo recommends the use of oils with the American Petroleum Institute (\
API) label. This
label certifies that the oil conforms to the applicable standards and sp\
ecifications of the

Engine Mechanical Components

Torque manifold nuts

The manifold nuts should be torqued at the 600-1,200 mile (1,000-2,000 \
km) inspection. A loose
manifold could alter air/fuel ratio and cause an increase in emission an\
d/or poor driveability.

Valves

The valve clearance should be checked every 30,000 miles (48,000 km). \

Vacuum fittings, hoses and connections

Unstable idle, misfiring or poor emission control is often caused by lea\
king vacuum hoses or
connections. Check hoses and connections on distributor vacuum unit, EGR\
valve (where applicable)
and connections on heater control servo systems and hydraulic brake serv\
o.

Exhaust Gas Recirculation (EGR)

This system operates by returning some of the exhaust gases to the engin\
e to be recombusted: since this
lowers the combustion temperature the amount of nitrogen oxides released\
into the atmosphere is
reduced.
The EGR valve should be cleaned at the 60,000 mile inspection and therea\
fter cleaned every 25,000
miles (40,000 km).

Timing belt

The timing belt tensioner should be adjusted at the 600-1,200 mile (1,0\
00-2,000 km) inspection.

Engine Fuel System


The fuel injection system is all-electronic and is microprocessor contro\
lled. It can continually
compensate for variations in engine load, speed and temperature to give \
the best economy and power.
The most unique feature of the system is the air mass meter which measur\
es the mass of the inducted air
instead of the volume. In this way the system can make instantaneous adj\
ustments for changes in air
temperature or density, thus always assuring the best economy with the l\
owest possible exhaust
emissions. pg. 66 Servicing
Special Instructions for work on the fuel injection system

Extreme cleanliness is essential when working on the injection system. G\
reat care must be observed.
Injection system service should be handled by qualified technicians, usi\
ng equipment intended for this
service.

Fuel (line) filter

We recommend that this filter be changed every 60,000 miles (96,000 km)\
. The filter is replaced as one

complete unit.
Replace more frequently if contaminated fuel was introduced into the tan\
k.

Fuel system cap, tank, lines and connections

The ability of the fuel system to control hydrocarbon emissions is depen\
dent largely on a leak-free
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 vehic\
le. Repair if necessary.

Air cleaner

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

Checking and adjusting idle speed

Your Volvo is equipped with an electronically controlled idle speed syst\
em that requires no period
checking or adjustment.

Lamda-sond (oxygen sensor) system

This is an emission control system designed to reduce emissions and impr\
ove fuel economy. An oxygen
sensor monitors the composition of the exhaust gases leaving the engine.\
The exhaust gas analysis is fed
into an electronic unit which continuously influences the amount of fuel\
injected. This adjusts the air-
fuel ratio to provide optimum conditions for combustion and efficient re\
duction of the three major
pollutants (hydrocarbons, carbon monoxide and nitrogen oxides) through\
a 3-way catalytic converter. pg. 67 Servicing
