Ford Mondeo 4 Owners Manual

General information
1This system consists of the pulse-air
solenoid valve, the pulse-air valve itself,
contained in the filter housing, and the piping
- see illustration 2.1A. It injects filtered air
directly into the exhaust ports, using the
pressure variations in the exhaust gases to
draw air through from the filter housing; air will
flow into the exhaust only when its pressure is
below atmospheric. The pulse-air valve can
allow gases to flow only one way, so there is
no risk of hot exhaust gases...

components are worn or damaged, the
assembly must be renewed.
18Refitting is the reverse of the removal
procedure.
Pulse-air piping
Note:This component, and those around it,
will be very hot when the engine is running.
Always allow the engine to cool down fully
before starting work, to prevent the possibility
of burns.
19Disconnect the battery negative (earth)
lead - see Section 1 of Chapter 5.
20Remove the air mass meter and resonator
- refer to Chapter 4.
21Unbolt the exhaust manifold heat shield;...

2The function of these components is to
reduce the emission of unburned
hydrocarbons from the crankcase, and to
minimise the formation of oil sludge. By
ensuring that a depression is created in the
crankcase under most operating conditions,
particularly at idle, and by positively inducing
fresh air into the system, the oil vapours and
“blow-by” gases collected in the crankcase
are drawn from the crankcase, through the oil
separator, into the inlet tract, to be burned by
the engine during normal...

hence the heat shields on the vehicle
underbody - and the casing will become
hot enough to ignite combustible
materials which brush against it. DO NOT,
therefore, park the vehicle in dry
undergrowth, over long grass or piles of
dead leaves.
(k) Remember that the catalytic converter is
FRAGILE. Do not strike it with tools
during servicing work, and take great care
when working on the exhaust system (see
Chapter 4). Ensure that the converter is
well clear of any jacks or other lifting gear
used to raise...

The independent front suspension is of
MacPherson strut type, incorporating coil
springs, integral telescopic shock absorbers,
and an anti-roll bar. The struts are attached to
steering knuckles at their lower ends, and the
knuckles are in turn attached to the lower
suspension arm by balljoints. The anti-roll bar
is bolted to the rear of the subframe, and is
connected to the front suspension struts by
links (see illustration).
On Saloon/Hatchback models, the
independent rear suspension is of
“Quadralink”...

pressed-steel lower side arms. A tie-bar on
each side supports the rear suspension
knuckles. The coil springs are separate from
the shock absorbers (see illustration).
A rear anti-roll bar is fitted to all models. On
SI models, the front and rear shock absorbers
are gas-filled; on other models, they are filled
with fluid. Self-levelling rear shock absorbers
are fitted as standard to Ghia Estate models.
A variable-ratio type rack-and-pinion
steering gear is fitted,...

Since most of the procedures dealt with in
this Chapter involve jacking up the vehicle
and working underneath it, a good pair of axle
stands will be needed. A hydraulic trolley jack
is the preferred type of jack to lift the vehicle,
and it can also be used to support certain
components during removal and refitting
operations. 
Warning: Never, under any
circumstances, rely on a jack to
support the vehicle while working
beneath it. When jacking up the vehicle, do
not lift or support it beneath the front...

11Locate one of the circlips in the outer
groove of the knuckle.
12Press or drive the new bearing into the
knuckle until it contacts the circlip, using a
length of metal tube of diameter slightly less
than the outer race. Do not apply any
pressure to the inner race.
13Locate the remaining circlip in the inner
groove of the knuckle.
14Support the inner race on a length of
metal tube, then press or drive the hub fully
into the bearing.

assembly as described in Section...
