Check the belt regularly to make sure it is in good condition and is cle\
an. A worn or dirty belt can cause
poor cooling and low alternator output as well as impair the operation o\
f the power steering and the air
conditioning unit.
NOTE: The drive belt is equipped with a self-tensioning mechanism and require\
s no adjustment
between changes.
WARNING!
The engine must not be running when this check is
performed.
Check coolant level
The cooling system must be filled with coolant and not leak to operate a\
t maximum efficiency. Check
the coolant level regularly. The level should be between the "MAX" and "\
MIN" marks on the expansion
tank. The check should be made with particular thoroughness when the eng\
ine is new or when the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Fre\
quent removal may prevent
coolant circulation between the engine and the expansion tank during eng\
ine warm up and cooling.
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.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle
cools.

slowly so that the overpressure dissipates.

Charge air cooler (Intercooler)
Turbocharged engines employ a turbocompressor to force air into the engi\
ne inlet manifold and a charge
air cooler to cool the compressed inlet air. The resulting increase in a\
ir flow raises pressure in the intake
manifold and increases engine power over that developed by the normally-\
aspirated engine. The charge
air cooler (which resembles a radiator) is located between the turbo-c\
ompressor and inlet manifold.
Fuel system
The engine is equipped with a multiport fuel injection system.
