The vehicle's ignition key or the stud on the edge of the supplied torqu\
e wrench can be used to undo or
tighten the cover. Turn a quarter turn (90 degrees). See illustration.\

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

Engine oil
Oil specifications
Engine oil must meet the minimum ILSAC specification GF-3, API SL, and A\
CEA A1/ B1. Lower
quality oils may not offer the same fuel economy, engine performance, or\
engine protection.

Washer fluid reservoir
The washer fluid reservoir is located in the engine compartment and hold\
s approx. 6.8 US qts (6.4 liters)
or 4.8 US qts (4.5 liters) on the V70 R.
During cold weather, the reservoir should be filled with windshield wash\
er solvent containing antifreeze.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and an\
tifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/ 50 mix of wat\
er and antifreeze).

CAUTION!
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.
Check coolant regularly!
WARNING!
l Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle cools.
l If it is necessary to top up the coolant when the engine is warm, unscre\
w the expansion tank cap
slowly so that the overpressure dissipates.

Fluids
Clutch and brake fluid reservoir
The clutch and brake fluid should always be above the MIN mark on the si\
de of the reservoir. Check,
without removing the cap, that there is sufficient fluid in the reservoi\
r.
Fluid type: DOT 4+ boiling point >536 °F (280 °C), P/N 9437433.
Replace: Every second year or 30,000 miles (48,000 km). The fluid should be rep\
laced once a year or
every 15,000 miles (24,000 km) when driving under extremely hard condi\
tions (mountain driving, etc.).
Always entrust brake fluid changing to an authorized Volvo retailer.
