2008 VOLVO S40 service

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).

Fluids
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.
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 a trained and
qualified Volvo service technician.
Power steering fluid
The fluid level is checked at each service interval.

Battery
Battery maintenance
ProCarManuals.com

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.

Replacing bulbs
Introduction
Before replacing bulbs in your vehicle, please keep the following points in mind:

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 should only be replaced by a trained and qualified Volvo service technician:

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.
