Periodic maintenance helps minimize emissions
Periodic maintenance will help keep your vehicle running well. Your Warranty and Service Records Information
booklet provides a comprehensive periodic maintenance schedule up to 150,000 miles (240,000 km) of vehicle service.
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. Replace the engine air filter cartridge with a new one
every 37,500 miles (60,000 km) under normal driving conditions. 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 105,000 miles (168,000 km). The filter is replaced as one 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 filler cap, tank and lines and connections
The ability of the fuel system to contain hydrocarbons is dependent 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 type 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 engine and 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 at
105,000 miles (168,000 km) and thereafter, at 150,000 mile (240,000 km) intervals.
Spark plugs
The spark plugs should be replaced every 60,000 miles (96,000 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.
