Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth
noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce
freeze protection. This gives protection against freezing down to -31°\
F (-35°C). See section "Coolant".
The use of "recycled" antifreeze is not approved by Volvo. Different typ\
es of antifreeze must not
be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo
retailer stocks plenty of Volvo engine coolant to protect your vehicle d\
uring cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. \
In
addition, in extremely cold weather conditions it is worthwhile to add f\
uel line de-icer before refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-
weather starting as well as decreasing fuel consumption while the engine\
is warming up. For winter use,
5W-30 oil, particularly the synthetic type
1, is recommended. Be sure to use good quality oil but do not
use cold-weather oil for hard driving or in warm weather. See section "E\
ngine oil" for more information.
l The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc\
.
are used more often. Moreover, the capacity of the battery decreases as \
the temperature drops. In very
cold weather, a poorly charged battery can freeze and be damaged. It is \
therefore advisable to check the
state of charge more frequently and spray an antirust oil on the battery\
posts.
l Volvo recommends the use of snow tires on all four wheels for winter driving - see section "Wheels
and tires."
l To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see

reserve capacity as the original (See the decal on the battery).
WARNING!
The distributor ignition system operates at very high voltages. Special \
safety precautions must be
followed to prevent injury. Always turn the ignition off when:
l Replacing distributor ignition components e.g. plugs, coil, etc.
l Do not touch any part of the distributor ignition system while the engin\
e is running. This may
result in unintended movements and body injury.

Engine specifications
1. Automatic transmission: 220 kW at 100 rps, 300 hp at 6000 rpm.
2. Automatic transmission: 350Nm at 32-100 rps, 258 ft. lbs at 1850-6000\
rpm.
Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the eng\
ine inlet manifold and a
charge air cooler to cool the compressed inlet air. The resulting increa\
se in air flow raises pressure in the
intake manifold and increases engine power over that developed by the no\
rmally-aspirated engine. The
charge air cooler (which resembles a radiator) is located between the \
turbo-compressor and inlet
manifold.
Fuel system
The engine is equipped with a multiport fuel injection system.
