shown that extremely weak anti-freeze solutions (10-25 percent) are very unfavorable from the point of
view of rust protection. For this reason, the quantity of anti-freeze/summer coolant should amount to

about 50 percent of the solution, that is 5.0 US qts. = 4.3 Imp qts = 4.8 liters, this lowers the freezing
point to -31° F (-35° C).
Alcohol must not be used as an anti-freeze agent since it evaporates at normal engine temperature.
Engine fuel system
During the wintertime with large variations in temperature, condensation forms in the fuel tank and can
impair the running of the engine. This can be eliminated by adding special additives to the fuel. There is
less risk of condensation forming in the fuel tank if it is kept full.
Engine lubricating system
During the winter, multigrade oil 10W-40 should be used in the engine. At very low temperatures
(below 0° F), multigrade oil SAE 5W-20 or SAE 5W-30 is recommended. These oils reach the
lubricating points in the engine more easily at low temperature and also facilitate cold starting. See
48.
Electrical system
The electrical system in the vehicle is subject to great stresses during the winter than during the warm
summer months, because the electrical equipment and starter motor are used more often. Since the
capacity of the battery is also considerably lower at low air temperature, it should also be checked more
often and, if necessary, charge the battery. If the battery voltage is excessively low, it may become
damaged by frost.
Brake system
During cold weather the brakes are subject to splash and condensation which can result in the parking
brake freezing up if applied for long periods of time. Use of first or reverse gear on a manual
transmission or position "P" on an automatic transmission is preferable during these conditions. See
page 39.
Windshield washers
Anti-freeze should also be added to the water container for the windshield (rear window) washer.
This is particularly important during the winter because the windshield frequently becomes dirty and is
often splashed with water which rapidly freezes and thus necessitates the frequent use of the windshield
washer and wipers. Your Volvo dealer can supply you with suitable anti-freeze for this purpose.
Anti-freeze for door locks
Lubricate the outside locks with a suitable anti-freeze. Such agents are commercially available and
WWW.MANUALS.WS
should be used before the first frost.
