Air pump system (B5254S)
When the engine is being started from cold, an electrical air pump which\
draws air to the exhaust system
is activated. This starts an afterburning process which leads to reduced\
hydrocarbon and carbon
monoxide (HC and CO) emissions and reduces the warm-up period for the \
catalytic converter.
The pump starts when the car has been started and is moving. It continue\
s to work until the catalytic
converter has reached normal working temperature, although it can also s\
tart when the engine is idling.
If the air pump is running and the engine is switched off, the pump cont\
inues working in order to protect
the pump motor.
Note! A soft whining noise can be heard from the pump, and when it perfo\
rms a self-diagnosis, the high/
low beam and the instrument lighting will flash briefly. This is complet\
ely normal. pg. 8:15 Windshield washer nozzles, Washer fluid reservoir
Adjusting washer nozzles
The washer jets should spray the windshield as shown above. Use the edge\
of a small screwdriver to
adjust the nozzles if necessary.

Normally, the coolant does not need to be changed. If the system must be\
drained, use the following
procedure:
1 Remove the expansion tank cap.
2 Move the temperature adjustment control to max. heat. Open the drain c\
ocks at the rear left of the
engine block and at the bottom right corner of the radiator.
3 Disconnect the lower right radiator hose.
Filling:
4 Close the drain cocks and reconnect the hose.
5 Fill the expansion tank to the MAX mark or slightly above.
6 Run the engine until hot. Check the cooling system connections for tig\
htness. Recheck the coolant
level.
Capacity: Approx. 7.6 US qts. (7.2 liters)
Turbo - 7.4 US qts. (7.0 liters)
Coolant: Volvo Genuine Coolant/Antifreeze only
NOTE: Do not top up with water only. Water by itself reduces the rust-pr\
otective and anti-freeze
qualities of the coolant and has a lower boiling point. It can also caus\
e damage to the cooling system if it
should freeze.
WARNING: If the engine is warm and you are going to top up coolant, unsc\
rew the cap slowly in
order to allow any excess pressure to escape.
