Changing oil filter

The oil level should be checked each time the

grade oil SAE 5W-20 or SAE 5W-30 is recom-

Driving under adverse conditions such as
high ambient temperatures, trailer hauling,
hill climbing, driving long distances at high
speeds, extended periods of idling, low speed

Changing oil filter

Every two years or 30.000 miles (50.000 km the
cooling system should be drained, flushed and
remove the expansion tank cap.
Open the drain cocks on both sides on both sides of the
engine block and disconnect the lower radi-
ator hose.
Fill coolant through the expansion tank.
The heater controls should be fully open
when draining and filling.

Add coolant until the level is up to the MAX
mark or slightly above.

Start engine and run until hot. Check the
cooling system connections for tightness. Also
re-check the coolant level.

The belt tension can be checked by depressing
the fan belt at a point midway between the

Change spark plugs

Replace the air cleaner cartidge with a new
one every 30,000 miles (50,000 km) The car-
tridge 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.

These checks should be made every 15,000
miles (25.000 km). California models, however,
only after the first 600-1,200 miles (1,000-
2,000 km).
The idling speed should also be adjusted and
the mixture ratio and manifold balance
checked at the first time.

The spark plugs should be changed every
30,000 miles (50,000 km).
However, city driving or fast highway driving
may require changing after 7,500 miles (12,500
km) of driving. When fitting new plugs, be sure
to fit the right type (Volvo Part No. 273593-4 or
equivalent). Torque to 7-10 ft.lbs. 10-14 Nm).

Special instructions for work on the
fuel injection system

Fuel (line) filter

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

Extrme cleanliness is essential when working
on the injection system. great care must be
Injection system services should be handled by
qualified technicians, using equipment inten-
ded for this servive.

The fuel filter is located on the firewall. This
filter is to be changed every 30,000 miles
(50,000 km). The filter is replaced as one com-
plete unit.
Replace more frequently if contaminated fuel
was introduced into the tank.

Fuel (91 octane RON)


Unleaded fuel is required for models with
catalytic converter (all models).
A label on the instruments panel and on the rear
fender, near the filler inlet, will remind of this
It is unlawful to dispense leaded fuel into a
vehicle labeled : unleaded gasoline only".

The B28F engine is provided with a fuel injec-
tion system called the CI system (Continuous
Injection). Fuel injectors are open and inject
fuel as long as the engine is operating.
This system has few moving parts, is reliable
and meets the exhaust emission standards at
maximum efficiency.
Air supplied to the engine is continuously
measured and determines the amount of fuel
The air flow is regulated by two throttle valves.
The air flow sensor and the fuel distributor are
integrally built as a single unit. A lever is
actuated by the air flow to produce continuous
fuel distribution.

Ignition timing

Crackcase ventilation

The ignition timing should be inspected at the 600-1,200 mile (1,000-
2,000 km) insection. All adjusting work should be done with pro-
per equipment. The distributor is one of the most sensitive engine
units. Careless handling can be lead to decreased engine output and high
fuel consumption or even serious damage to the engine.

The engine is provided with positive crankcase ventilation which
prevents crankcase gases from being released inti the atmosphere.
Instead, the crankcase gases are admitted to the intake manifold and

Cleaning PCV valve

The calibrated positive crankcase ventilation valve should be cleaned
every 60,000 miles. Rubber hoses should be checked for damage at the
same time. Replace if necessary.

Catalytic converter

This is a supplementary device in the exhaust
system, designed to clean the remaining dirty
exhaust gases.
This device is mainly a container with a
ceramic material insert, designed to let the
exhaust gases pass through channels in the
insert. The channel walls are covered by a thin
layer of platina-palladium. These metals act as
catalysy, permitting a chemical action action to
occur without actually taking part in it.
The CO content will increase if the Catalytic
Converter is damaged.

Evaporative control system

Vehicles intended for the North American markets are equipped with a
gas evaporative control system, which prevents gasoline fumes from
being released into the atmosphere.
The system consists of an expansion space in the fuel tank, a pressure
relief valve and a charcoal filter.
The components are interconnected by hoses which channel fuel
vapor from the gas tank to the charcoal filter where it is stored until
the engine is started and then drawn into the engine fuel induction

Fluid type: Automatic Transmission Fluid type F or G
Replace: at 600-1,200 mile (1,00-2,000 km) service only.

The oil level should be up to the filler plug (A). Drain the oil immediately
after driving, while it is still hot by remving plug (B).
Transmission and overdrive are lubricated by the same oil. Therefore,
when the oil is drained through plug B, also remove cover on the over-
drive and clean strainer.

Check the oil level as follows:
Park the car on flat ground with the engine idling
Slowly move selector, lever through all gear positions and then
to position P. Wait 2 minutes before checking the oil level. As the
illustrations shows, the dipstick has a "cold" and a "warm" side.
The oil level should be between the MIN and MAX marks.
Wipe the dipstick with a clean cloth. CAUTION! The oil may be very hot!
Do not use rags with can leave lint on the dipstick.
The transmission is topped up via the dipstick tube.
The space between the MIN and MAX marks on the dipstick corre-
sponds to 0,5 liter. Do not fill the transmission with too much oil, since
this can result in oil being ejected from the transmission.
Too little oil, on the other hand, can negatively affect transmission
operation, particularly in very cold weather.

During winter, locks in the doors and trunk lid

Check coolant level

Top up with coolant

The cooling system must be filled with
coolant and not leak to operate at maximum
efficiency. Check the coolant level when
filling fuel. The level should be between
the "Max." and "Min" marks on the ex-
pansion tank. The check should be made
with particular thoroughness when the engine
is new or 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
warming up and cooling.
Top up with coolant by filling the expansion
tank when level is at the "Min" mark. Use a
mixture of 50 % anti-freeze/summer coolant
and 50 % water all the year round. Top up to
the "Max" mark.
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.
