SERVICING
Engine fuel system
During the wintertime with large variations
i n temperature, condensation water forms
i n the fuel tank and can impair the running
of the engine. This can be eliminated by
adding suitable carburettor spirit (but not
methylated spirit) to the fuel. Add spirit
before filling the fuel tank with fuel. Also,
there is less risk of condensation water
forming if the tank is kept well-filled.
Engine lubricating system
During the winter multigrade oil or engine
oil SAE 10 W should be used for the en-
gine lubricating system. At very low tem-
peratures (below -20
°
C = -4
°
F) multi-
grade
oil
SAE 5 W-20 is recommended.
These oils reach the lubricating points in
the engine more easily at low temperature
and also facilitate cold starting. See page
41.
Electrical system
The electrical system in the vehicle is sub-
jected to greater stresses during the win-
ter than during the warm summer months.
The lighting and starter motor are used
more and since the capacity of the battery
i s also considerably lower at low air tem-
perature, the state of charge must be
checked more often and, if necessary, the
battery charged. If the battery voltage is
excessively low, there is risk of the battery,
being damaged by frost.
Brake system
During very cold weather the brakes are
subjected to splash and condensation wa-
ter which can result in the parking brake
freezing up if left on.
When you park the car, do not apply the
parking brake but engage first gear or re-
verse and if possible place blocks behind
the wheels. See also page 27.
Windscreen washer
Just as anti-freeze is added to the cooling
system during the winter to prevent frost
damage, anti-freeze should also be added
to the water container for the windscreen
washers. This is particularly i mportant be-
cause the windscreen during the winter
frequently
becomes dirty and is often
splashed with water which rapidly freezes
and thus necessitates the frequent use of
the windscreen washer and wipers. Your
Volvo dealer can supply you with suitable
anti-freeze for this purpose.
Anti-freeze for door locks
A frozen door lock is one the most irri-
tating
things that can happen
to a car
owner. Many valuable minutes early in the
morning can be wasted warming up keys
and melting ice in locks. Remember this
i n good time and lubricate the locks in ad-
vance with some suitable anti-freeze agent.
Such agents are now available in small
handy tubes which can easily find room in
a handbag or coat pocket.
