support frame and under the reinforced plate in the spare wheel well. Ta\
ke care not to damage the splash
guard under the engine. Ensure that the jack is positioned so that the c\
ar cannot slide off it. Always use
axle stands or similar structures.


If a two-post hoist is used to lift the car, the front and rear lift arm\
pads should be centered under the
reinforced lift plates on the inboard edge of the sill rail. The positio\
n of these plates is marked with
arrows molded into the bottom of the sill rail.
CAUTION: 850 R turbo models have reduced ground clearance due to the des\
ign of the front spoiler.
Please observe caution when driving the car onto a garage hoist.

Torque exhaust and intake manifold nuts

A loose manifold could alter air/fuel ratio and cause an increase in emi\
ssion and/or poor driveability.

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. Th\
e filter cannot be cleaned and
therefore should always be replaced with a new one.

Vacuum fittings, hoses and connections

9:59:52 AMClassic Cars & Cycles www.ClassicCycles.org

1996 Volvo 850

Unstable idle, misfiring, or poor emission control is often caused by le\
aking vacuum hoses or
connections. Check all vacuum hoses and connections.

Checking and adjusting idle air control system

Your Volvo is equipped with an electronically controlled idle air contro\
l system that requires no
checking or adjustment.

Timing belt

For proper functioning of the vehicle and its emission control systems, \
Volvo recommends that the
timing belt be replaced every 70,000 miles (112,000 km).

Fuel system cap, tank and lines and connections

The effectiveness of the fuel system to contain hydrocarbons is dependen\
t largely on a leak-free system.
Check for proper sealing of the gasoline filler cap which contains "O" r\
ing type seals.

Fuel (line) filter

The fuel line filter is located next to the fuel pump. For proper functi\
oning of the vehicle and its
emission control systems, the fuel line filter should be replaced at 100\
,000 miles (160,000 km). The
filter is replaced as one complete unit. Replace more frequently if cont\
aminated fuel is introduced into
the tank (or if there is reason to suspect that this has occurred).

Charge air cooler (Intercooler)

The B 5234 Turbo engine employs a turbo-compressor to force air into the\
engine inlet manifold and a
charge air cooler to cool the compressed inlet air. The resulting increa\
se in air flow raises pressure in the
intake manifold by approx. 8.7 psi (over atmospheric pressure) and eng\
ine power output by approx. 50
horsepower over that developed by the normally-aspirated engine. The cha\
rge air cooler (which
resembles a radiator) is located between the turbo-compressor and inlet\
manifold.

Fuel System

The fuel system is all-electronic and is microprocessor-controlled. It c\
an 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 instan\
taneous adjustments for
changes in air temperature or density, thus always assuring the best eco\
nomy with the lowest possible
exhaust emissions.

Heated oxygen sensor

This is an emission control system designed to reduce emissions and impr\
ove 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 rat\
io to provide optimum conditions
for combustion and efficient reduction of the three major pollutants (h\
ydrocarbons, carbon monoxide
and oxides of nitrogen (NOx) by a three-way catalytic converter.

Secondary Air Injection (certain models)

This system adds air to the hot exhaust gases as they are expelled from \
the engine. This causes a
secondary combustion of residual hydrocarbons and carbon monoxide, resul\
ting in lower emissions
levels in the exhaust gases.

Evaporative control system

The car is equipped with a gas evaporative control system, which prevent\
s gasoline fumes from being
released into the atmosphere. The system is comprised of an expansion ch\
amber in the fuel tank, a roll-
over valve on the cross member in front of the fuel tank and a charcoal \
canister with a built-in vacuum
valve under the left-front wheel housing. The components are interconnec\
ted by hoses which channel
fuel vapor from the gas tank to the charcoal filter, where it is stored \
until the engine is started and then
drawn into the engine's air intake system.


Crankcase ventilation

The engine is provided with positive crankcase ventilation which prevent\
s crankcase gases from being
released into the atmosphere. Instead, the crankcase gases are admitted \
to the intake manifold and
cylinders.

PCV system

The orifice nipple in the intake manifold and the filter at the end of t\
he PCV hose in the air cleaner
should be inspected every 60,000 miles (96,000 km). Check/replace rubb\
er hoses at the same time. pg. 8:9 Lubrication

pg. 8:10 Engine oil
Checking the oil level

The oil level should be checked every time the car is refuelled. This is\
especially important during the
engine break-in period (up to the first service).
CAUTION : Not checking the oil level regularly can result in serious eng\
ine damage if the oil
becomes too low.
