engine VOLVO S40 2007 Workshop Manual

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 53
) 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.
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
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 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).

Fluids
CAUTION
ProCarManuals.com

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.
Brake fluid
The brake fluid should always be between the MIN and MAX marks on the side of the reservoir. Check, without removing
the cap, that there is sufficient fluid in the reservoir.
Fluid type : DOT 4+ boiling point >536°F (280°C), P/N 9437433
Replace : The fluid should be replaced according to the intervals specified in the Warranty and Service Records
Information booklet. When driving under extremely hard conditions (mountain driving, etc), it may be necessary to replace
the fluid more often. Consult your Volvo retailer. Always entrust brake fluid changing to an authorized Volvo retailer.
Power steering fluid
The fluid level is checked at each service interval.
Fluid type : Volvo power steering fluid or equivalent.
Replace : No fluid change required.
WARNING
If a problem should occur in the power steering system or if the vehicle has no electrical current and must be towed, it is
still possible to steer the vehicle. However, keep in mind that greater effort will be required to turn the steering wheel.

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
PROPOSITION 65 WARNING!
Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the state of
California to cause cancer and reproductive harm. Wash hands after handling.

Removing the battery
1. Switch off the ignition and remove the key.
2. Wait at least 5 minutes after switching off the ignition before disconnecting the battery so that all information in the
vehicle's electrical system can be stored in the control modules.
3. Remove the cover over the battery.
4. Disconnect the battery negative (ground) cable.
5. Disconnect the positive cable.
6. Remove the front side of the battery box with a screwdriver.
7. Release the clamp holding the battery.
8. Lift out the battery.
Installing a new battery
1. Put the battery in place in the engine compartment.
2. Install the battery's retaining clamp.

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.
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 an authorized Volvo retailer.
WARNING
Never use fuses with higher amperage than those stated in the following tables. Doing so could overload the vehicle's
electrical system.

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.
5. Close the fuse box in reverse order.
6. Pull the center pins fully out of the mounting clips, secure the upholstery with the mounting clips and press the pins into
the mounting clips again. The mounting clips then expand, holding the upholstery in position.

NOTE
ProCarManuals.com

The transmission oil does not normally need to be changed during the service life of the vehicle. However, it may be
necessary to replace the oil if the vehicle is often driven in areas of sustained temperature extremes (hot or cold), when
towing a trailer over long distances, for prolonged driving in mountainous areas, or if the vehicle is often driven short
distances in temperatures under 40°F (5°C).

Engine oil
Oil specifications
Engine oil must meet the minimum ILSAC specification GF-3, API SL, and ACEA A1/B1. Lower quality oils may not
offer the same fuel economy, engine performance, or engine protection.
Volume: 6.1 US qts (5.8 liters).
Volume between the MIN and Max marks on the dipstick: approximately 1.4 US qts (1.3 liters).
Volvo recommends
.
Depending on your driving habits, premium or synthetic oils may provide superior fuel economy and engine protection.
Consult your Volvo retailer for recommendations on premium or synthetic oils.
Oil additives must not be used.
NOTE
Synthetic oil is not used when the oil is changed at the normal service intervals. This oil is only used at customer
request, at additional charge. Please consult your Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 86° F (30° C) in your area, Volvo recommends, for the protection of your engine, that you
use a heavier weight oil, such as such as SAE 5W -40 or 0W -40. See the viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when temperatures do not exceed 86° F (30° C), SAE
5W -30 will provide good fuel economy and engine protection. See the viscosity chart.
ProCarManuals.com

Extreme engine operation
Synthetic oils meeting SAE 0W -30 or 0W -40 and complying with oil quality requirements are recommended for driving
in areas of sustained temperature extremes (hot or cold), when towing a trailer over long distances, and for prolonged
driving in mountainous areas.
