manifold. Piston blow-by gases are drawn
through the oil separator and the vent valve to
the inlet manifold. The blow-by gases are then
drawn into the engine together with the fuel/air
mixture. Refer to Chapter 1 for maintenance of
the system.
The following operations can be carried out
without removing the engine from the vehicle.
a)
Removal of the camshafts.
b) Removal and servicing of the cylinder
head.
c) Removal of the timing chain and
sprockets.
d) Removal of the oil pump.
e) Removal of the sump.
f) Removal of the pistons and connecting
rods.
g) Removal of the big-end bearings.
h) Removal of the engine mountings.
i) Removal of the clutch and flywheel.
j) Removal of the crankshaft front and rear
oil seals.
The following operations can only be carried
out after removing the engine from the vehicle.
a)
Removal of the crankshaft main bearings.
b) Removal of the crankshaft.
Note: A hoist and lifting tackle will be required
to lift the engine out of the vehicle.
1 Disconnect the battery negative lead.
2 Remove the bonnet.
3 On carburettor models, remove the air cleaner.
4 On fuel-injection models, remove the air
inlet hose, plenum chamber and air cleaner lid
as an assembly.
5 Disconnect the breather hose from the
camshaft cover, and unscrew the bolt
securing the hose support bracket to the left-
hand side of the cylinder head (see
illustration).
6 Drain the cooling system.
7 To provide additional working space,
remove the radiator.
8 Disconnect the coolant hoses from the
water pump housing on the left-hand side of
the engine and the cylinder head (see
illustration).
9 Disconnect the coolant hoses from the
thermostat housing.
10 Disconnect the heater coolant hose from
the inlet manifold.
11 Where applicable, release the coolant
hose from the bracket under the carburettor
automatic choke housing.
12 Disconnect the throttle cable and (where
necessary) speed control cable from the
throttle linkage.
13 On carburettor models, disconnect the
vacuum pipe from the engine management
module.
14 Disconnect the brake servo vacuum hose
(where necessary) from the inlet manifold.
15 On fuel-injection models, disconnect the
vacuum pipes from the MAP sensor (located
on the suspension turret on the right-hand
side of the engine compartment) and, where
applicable, the air conditioning system.
16 On carburettor models, disconnect the
fuel supply and return hoses at the
carburettor, and plug the ends of the hoses to
minimise petrol spillage. Take adequate fire
precautions.
17 On fuel-injection models, slowly loosen
the fuel feed union at the fuel rail to relieve the
pressure in the fuel system before
disconnecting the union. Be prepared for
petrol spillage and take adequate fire
precautions. Disconnect the fuel feed hose, and disconnect the fuel return hose from the
fuel pressure regulator. Plug the ends of the
hoses to minimise petrol spillage.
18 Disconnect the HT lead from the ignition
coil, and unclip it from the timing chain cover.
19 Disconnect the wiring from the following
components as applicable, depending on
model. Then free the wiring loom from any
necessary retaining clips or ties and position it
clear of the engine.
a)
Alternator.
b) Starter motor.
c) Oil pressure warning lamp switch.
d) Temperature gauge sender.
e) Cooling fan switch.
f) Anti-dieselling valve (carburettor models).
g) Automatic choke heater (carburettor
models).
h) Engine coolant temperature sensor.
i) Crankshaft speed/position sensor.
j) Air charge temperature sensor.
k) Throttle position sensor.
l) Fuel temperature sensor.
m) Fuel injectors.
20 Remove the water pump/alternator
drivebelt, then unbolt the power steering
pump from the mounting bracket and move it
clear of the engine. Note that there is no need
to disconnect the fluid hoses, but make sure
that the pump is adequately supported to
avoid straining them.
21 On models fitted with air conditioning,
unbolt the air conditioning compressor from the
mounting bracket, and move it clear of the
engine (see illustration). Do not disconnect the
hoses, but make sure that the compressor is
adequately supported to avoid straining them.
22 Unscrew and remove the top engine-to-
gearbox bolts which are accessible from the
engine compartment. Note the location of the
bolts, and the positions of the earth strap and
any wiring clips attached to the bolts.
23 Unscrew the securing bolt, and
disconnect the earth lead from the rear left-
hand side of the cylinder head.
24 Unscrew the nuts securing the engine
mountings to the engine mounting brackets.
25 Apply the handbrake, jack up the front of
the vehicle and support it securely on axle
stands (see “Jacking”).
26 Drain the engine oil into a container.
5 Engine - removal leaving manual
gearbox in vehicle
4 Major operations requiring
engine removal
3 Major operations possible with
the engine in the vehicle
2B•4 DOHC engine
5.5 Removing the hose support bracket
bolt from the cylinder head
5.8 Water pump coolant hoses (viewed
from above)
5.21 Air conditioning compressor mounting
bolts (arrowed) (viewed from underneath)
Warning: Vehicles equipped with
air conditioning: Components of
the air conditioning system may
obstruct work being undertaken
on the engine, and it is not always possible
to unbolt and move them aside sufficiently,
within the limits of their flexible pipes. In
such a case, the system should be
discharged by a Ford dealer or air
conditioning specialist. Refer also to the
precautions given in Chapter 3.
