Engine cooling system
A good quality anti-freeze should be used
all the year round. Thus, the cooling sys-
tem should always contain water plus
anti-freeze and rust inhibitor, even during
the summer.
Experience has also shown that extremely
weak anti-freeze solutions (10-25%
)
are
very unfavourable from the point of view of
rust protection. For this reason, the quan-
tity of anti-freeze should amount to about
50 %
of the coolant, that is, 6.2 litres
(11 Imp. pints = 13 US pints), this lowering
the freezing point to -35° C (-31° F).
Radiator spirit is not recommended as an
anti-freeze agent since it evaporates at
normal engine temperature.
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 5W-20 is recommended.
These oils reach the lubricating points in
the engine more easily at low temperature
and also facilitate cold starting. See page
43.
Engine fuel system
During the wintertime with large variation
i n temperature, condensation water forms
62
i n the fuel tank and this can impair the
running of the engine. This can be elimi-
nated 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.
Electrical system
The electrical system in the vehicle is sub-
j ected 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 25.
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 important 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 washers 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 of 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.
