fuel filter VOLVO XC90 2004 Owners Manual

2004 VOLVO XC90
Information booklet provides a comprehensive periodic maintenance schedu\
le up to 150,000 miles
(240,000 km) of vehicle maintenance. The schedule includes components \
that affect vehicle emissions.
This page describes some of the emission-related components.
Engine air filter
The engine air filter cleans particles from air entering the engine. Rep\
lace the engine air filter cartridge
with a new one every 37,500 miles (60,000 km) under normal driving con\
ditions. Replace the cartridge
more often when the vehicle is driven under dirty and dusty conditions. \
The cartridge cannot be cleaned,
and should always be replaced with a new one.
Fuel filter
The fuel filter should be replaced at 120,000 miles (193,000 km). The \
filter is replaced as a complete
unit. Replace more frequently if contaminated fuel is introduced into th\
e tank, or if there is reason to
suspect that this has occurred.
Fuel system, including filler cap, tank, lines, and connections
The ability of the fuel system to contain hydrocarbons depends upon a le\
ak-free system. Inspect fuel
lines every 30,000 miles (48,000 km). Check for proper sealing of the \
fuel filler cap, which contains "O"
ring seals.
NOTE: If the fuel filler cap is not closed tightly or if the engine is running\
when the vehicle is refueled,
the Check Engine light (Malfunction Indicator) may indicate a fault. H\
owever, your vehicle's
performance will not be affected. Use only Volvo original or approved fu\
el filler caps.
Timing belt
For proper functioning of the engine and emission control systems, the t\
iming belt and belt pretensioner
must be replaced every 120,000 miles (193,000 km). Engine damage will \
occur if the belt fails.
PCV system
(on turbocharged models)
The nipple in the intake manifold and the filter at the end of the PCV h\
ose in the air cleaner should be
inspected and cleaned at 120,000 miles (193,000 km), and again at 150,\
000 miles (240,000 km).
Spark plugs
The spark plugs should be replaced every 60,000 miles (96,000 km) unde\
r normal driving conditions.
City driving or fast highway driving may necessitate replacement sooner.\
Under normal driving conditions, spark plugs require no maintenance betw\
een replacement intervals.
When installing new plugs, be sure to use the right type and to tighten \
them correctly. When changing
the plugs, clean the terminals and rubber seals. Also check that the sup\
pressor connectors are in good
condition. Cracked or damaged connectors should be replaced.

Oil viscosity (stable ambient temperatures)
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86° F
(30° C), SAE 5W-30 will provide good fuel economy and engine protec\
tion. See the viscosity chart
above.
Extreme engine operation
Synthetic oils meeting SAE 10W-30 and complying with oil quality require\
ments 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.
Changing oil and oil filter
Oil and oil filter changes should be made at 7,500 mile (12,000 km) in\
tervals.
Volvo does not recommend the use of oil additives.
Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at
ower request and at additional charge. Please consult your Volvo retaile\
r.
l The API Service Symbol "donut" is divided into three parts:
l The top half describes the oil's performance level.
l The center identifies the oil's viscosity.
l The bottom half tells whether the oil has demonstrated energy-conserving\
properties in a standard test
in comparison to a reference oil.
