The fuel filter should be replaced at 105,000 miles (168,000 km). The filter is replaced as a complete unit. Replace
more frequently if contaminated fuel is introduced into the 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 leak-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 car is refueled, the Check Engine
light (Malfunction indicator) may indicate a fault. However, your vehicle's performance will not be affected. Use only
Volvo original or approved fuel filler caps.
Timing belt
For proper functioning of the vehicle and its emission control systems, the timing belt and belt tensioner must be
replaced every 105,000 miles (168,000 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 hose in the air cleaner should be inspected and
cleaned at 105,000 miles (168,000 km) and thereafter, again at 150,000 mile (240,000 km) intervals.
Spark plugs
The spark plugs should be replaced every 45,000 miles (72,000 km) under normal driving conditions. City driving or
fast highway driving may necessitate replacement sooner.
Under normal driving conditions, spark plugs require no maintenance between 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 suppressor connectors are in good condition. Cracked or damaged connectors
should be replaced.

pg. 112 Fuel/emissions systems
Fuel system
The fuel system is all-electronic and is microprocessor-controlled. It can continually compensate for variation in
engine load, speed and temperature to give the best economy and power. A mass air flow sensor measures the inducted
air. In this way the system can make instantaneous adjustments for changes in air temperature or density, thus always
assuring the best economy with the lowest possible exhaust emissions.
Heated oxygen sensor
This is an emission control system designed to reduce emissions and improve fuel economy. The heated oxygen sensor
monitors the composition of the exhaust gases leaving the engine. The exhaust gas analysis is fed into an electronic
module. This adjusts the air-fuel ratio to provide optimum conditions for combustion and efficient reduction of the
three major pollutants (hydrocarbons, carbon monoxide and oxides of nitrogen (NOx) by a three-way catalytic
converter.
Crankcase ventilation
The engine is provided with positive crankcase ventilation which prevents crankcase gases from being released into the
atmosphere. Instead, the crankcase gases are admitted to the intake manifold and cylinders.
Evaporative control system
The car is equipped with an evaporative control system which prevents gasoline vapor from being released into the
atmosphere.
The system consists of a fuel tank with filler pipe and cap, a rollover valve, a Fill Limit Vent Valve (FLVV), vapor
vent lines, a charcoal canister, a purge line, a purge control valve and engine connections. In addition, there is a
pressure sensor connected to the fuel tank and a filter -protected Canister Close Valve (CCV) on the atmospheric side
of the canister, for system diagnosis.
The gasoline vapor is channeled through the rollover valve and the FLVV via the vapor vent lines into the charcoal
canister, where it is stored. When the engine is started, the gasoline vapor is drawn from the charcoal canister to the
engine's air intake system and into the combustion process.
NOTE:
If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine light
