2008 VOLVO C70 engine

Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and
at additional charge. Please consult a trained and qualified Volvo service technician.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This is especially important during the period up to
the first scheduled maintenance service
The car should be parked on a level surface when the oil is checked.
If the engine is warm , wait for at least 10-15 minutes after the engine has been switched off before checking the oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lint-free rag.
2. Reinsert the dipstick, pull it out, and check the oil level.
3. Add oil if necessary. If the level is close to the MIN mark, add approximately 1 US quart (1 liter) of oil.
4. Run the engine until it reaches normal operating temperature.
5. Switch off the engine and wait for at least 10-15 minutes and recheck the oil level. If necessary, add oil until the
level is near the MAX mark.
CAUTION
Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
Oil that is lower than the specified quality can damage the engine.
Always add oil of the same type and viscosity as already used.
Never fill oil above the MAX mark. This could cause an increase in oil consumption.

Engine oil
WARNING
Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces
NOTE
Volvo uses different systems to indicate a low oil level or pressure. Some models have an oil pressure sensor, in
which case a warning symbol (see page 48
) is used to indicate low oil pressure. Other models have an oil level
sensor, in which case the driver is alerted by the warning symbol in the center of the instrument panel and a text in
the information display. Some models use both systems. Contact an authorized Volvo retailer for more information.
211 09 Maintenance and servicing
Fluids
Washer fluid
The washer fluid reservoir is located in the engine compartment and holds approximately 6.8 US qts (6.5 liters).
During cold weather, the reservoir should be filled with windshield washer solvent containing antifreeze.
Coolant
ProCarManuals.com

Normally, the coolant does not need to be changed. If the system must be drained, consult a trained and qualified
Volvo service technician.
NOTE
Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has a
lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water and antifreeze).
CAUTION
The cooling system must always be kept filled to the correct level, and the level must be between the MIN and
MAX marks. If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Different types of antifreeze/coolant may not be mixed. Check coolant regularly!
WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools. If it is necessary to top off the
coolant when the engine is warm, unscrew the expansion tank cap slowly so that the overpressure dissipates.

Battery
Battery maintenance
Driving habits and conditions, climate, the number of starts, etc., all affect the service life and function of the battery.
In order for your battery to perform satisfactorily, keep the following in mind:
Check the fluid level in each cell in the battery every 24 months or every 15,0001 miles (24,000 km), whichever is
sooner. The fluid should be at the level shown in the illustrations above (A). Do not overfill.
1More frequently in warm climates.
Use a screw driver to open the caps or cover and a flashlight to inspect the level.
If necessary, add distilled water. The level should never be above the indicator (A).
The fluid level should be checked if the battery has been recharged.
After inspection, be sure the cap over each battery cell or the cover is securely in place.
Check that the battery cables are correctly connected and properly tightened.
Never disconnect the battery when the engine is running, or when the key is in the ignition. This could damage the
vehicle's electrical system.
The battery should be disconnected from the vehicle when a battery charger is used directly on the battery.
WARNING
ProCarManuals.com

Installing a new battery
1. Put the battery in place in the engine compartment.
2. Install the battery's retaining clamp.
3. Reinstall the front side of the battery box.
4. Connect the positive cable.
5. Connect the ground cable.
6. Reinstall the cover over the battery.
NOTE
Used batteries should be properly disposed of at a recycling station or similar facility, or taken to your Volvo
retailer.
WARNING
Never expose the battery to open flame or electric spark.
Do not smoke near the battery.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If
contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.

Replacing bulbs
Introduction
Before replacing bulbs in your vehicle, please keep the following points in mind:
NOTE
Never touch the glass of bulbs with your fingers. Grease and oils from your fingers vaporize in the heat and will
leave a deposit on the reflector, which will damage it.
The optional Bi -Xenon® headlight bulbs contain trace amounts of mercury. These bulbs should always be
disposed of by an authorized Volvo retailer.
Certain bulbs not listed here should only be replaced by an authorized Volvo service technician.
Certain bulbs should only be replaced by a trained and qualified Volvo service technician:
- Courtesy (dome) lighting
- Reading lights
- Glove compartment lights
- Turn signals and courtesy lights in the side door mirrors
- High-mounted brake lights
- Bi -Xenon® headlights

3. Pry carefully and lift out the entire mirror and the cover.
4. Remove the defective bulb and replace it with a new one.
5. To reinstall the mirror, begin by pressing the three lugs at the upper edge of the mirror back into place.
6. Press the three lower lugs back into place.
224 09 Maintenance and servicing
Fuses
Replacing fuses
There are relay/fuse boxes located in the engine compartment and the passenger compartment.
If an electrical component fails to function, this may be due to a blown fuse. The easiest way to see if a fuse is blown
is to remove it.
To do so:
1. Pull the fuse straight out. If a fuse is difficult to remove, special fuse removal tools are located on the inside of the
fuse box covers.
2. From the side, examine the curved metal wire in the fuse to see if it is intact.
3. If the wire is broken, insert a new fuse of the same color and amperage (written on the fuse).
If fuses burn out repeatedly, have the electrical system inspected by a trained and qualified Volvo service technician.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the following pages. Doing so could
seriously damage or overload the vehicle's electrical system.
225 09 Maintenance and servicing
Fuses
Fuse box in the engine compartment

The fuse box in the engine compartment has positions for 36 fuses.
Fuses 1-18 are relays/circuit breakers and should only be removed or replaced by an authorized Volvo service
technician.
Fuses 19-36 may be changed at any time when necessary.
Several extra fuses and a fuse removal tool to assist in removing/replacing fuses can be found on the underside of the
fuse box cover in the engine compartment.
226 09 Maintenance and servicing
Fuses
Fuse box in the passenger compartment
The fuse box in the passenger compartment is located under the glove compartment.
To access the fuses:
1. Remove the upholstery covering the fuse box by first pressing in the center pins in the mounting clips approximately
0.5 in (1 cm) with a small screwdriver and then pulling the pins out.
2. Turn both retaining screws (2) counterclockwise until they release.
3. Fold down the fuse box (3) half way. Pull it toward the seat until it stops. Fold it down completely. The fuse box can
be unhooked completely.
4. Replace the blown fuse.
