1) Replace at 105,000 miles (168,000 km)
2) Brake fluid should be changed at owner request every second year or 30,000 miles (48,000 km). The fluid
should be replaced once a year or every 15,000 miles (24,000 km) when driving under extremely hard
conditions (mountain driving, etc.).
3) Rotate tires at owner request.
The following items should be checked weekly by the driver (it takes only a few minutes):
Engine oil level, brake fluid level, radiator coolant level, operation of all lights, horns, windshield wipers, tire
pressure (all five tires), windshield washer fluid level
The following should also be carried out at regular intervals:
Washing (check all drain holes), polishing, cleaning
pg. 108 Servicing
Hoisting the car
If a garage jack is used to lift the car, the two jack attachments points should be used. They are specially reinforced to
bear the weight of the car. A garage jack can also be placed under the front of the engine support frame and under the
reinforced plate in the spare wheel well. Take care not to damage the splash guard under the engine. Ensure that the
jack is positioned so that the car cannot slide off it. Always use axle stands or similar structures.

If a twopost hoist is used to lift the car, the front lift arm pads should be positioned under the rear engine frame
mounts. The rear lift arm pads should be positioned under the rear supporting arm bracket.
CAUTION: Certain models have reduced ground clearance due to the design of the front spoiler. Please observe
caution when driving the car onto a garage hoist.
pg. 109 Servicing
Air cleaner
Replace the air cleaner cartridge with a new one every 30,000 miles (48,000 km). The cartridge should be replaced
more often when driving under dirty and dusty conditions. The filter cannot be cleaned and therefore should always be
replaced with a new one.
Timing belt
For proper functioning of the vehicle and its emission control systems, the timing belt and tensioner must be replaced
every 105,000 miles (168,000 km). Engine damage will occur if the belt fails.
Fuel system cap, tank and lines and connections
The effectiveness of the fuel system to contain hydrocarbons is dependent largely on a leakfree system. 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 Malfunction
Indicator Lamp ("Check Engine") may indicate a fault. However, your vehicle's performance will not be affected. Use
only Volvo original or approved fuel filler caps.
Fuel (line) filter
For proper functioning of the vehicle and its emission control systems, the fuel line 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).
PCV system
The orifice nipple in the intake manifold and the filter at the end of the PCV hose in the air cleaner should be

Spark plugs: Champion RC8PYP (or equivalent)
Spark plug gap: 0.03" (0.75 mm)
Tightening torque: 18.4 ft. lbs. +/ 3.7 ft. lbs. (25 Nm +/ 5 Nm)
WARNING!
The distributor ignition system operates at very high voltages. Special safety precautions must be followed to
prevent injury. Always turn the ignition off when:
· Replacing distributor ignition components e.g. plugs, coil, etc.
· Do not touch any part of the distributor ignition system while the engine is running. This may result in unintended
movements and body injury.
Replacing spark plugs
The spark plugs should be changed every 30,000 miles (48,000 km). However, city driving or fast highway driving
may necessitate changing after 15,000 miles (24,000 km) of driving. When installing new plugs, be sure to fit the right
type and use correct torque, see "Specifications". When changing the plugs, check that the suppressor connectors are in
good condition. Cracked or damaged connectors should be replaced. When changing the spark plugs, clean the
terminals and the rubber seals.
Front suspension
Spring strut suspension with integrated shock absorbers and control arms linked to the support frame. Powerassisted
rack and pinion steering. Safety type steering column.
The alignment specifications apply to an unladen car but include fuel, coolant and spare wheel.
Toe-in measured on the wheel rims: 2.4 mm +/ 0.7 mm

The following should be checked regularly: *
1 Washer fluid reservoir should be filled with water and solvent (wintertime: windshield washer anti-freeze). See
page 115.
2 Coolant level should be between the expansion tank marks. Mixture: 50% anti-freeze and 50% water. See page 116.
3 Power steering - When cold, the level must not be above the COLD mark and when hot it must not be above the
HOT mark. Top up if the level drops to the ADD mark with ATF fluid. See page 114.
4 Engine oil level should be between the dipstick marks. The distance between the marks represents approx.
1.6 US qts (1.5 liters). See page 112.
5 Brake fluid - check, without removing the cap, that the level is above the MIN mark. Use brake fluid DOT 4+. See
page 114.
* Engine oil should be checked each time the car is refuelled.
Octane rating, see page 57.
