Ford Mondeo 4 Owners Manual

(a) One from the rear of the throttle housing
(only the one hose - there is no need to
disconnect the second hose running to
the fuel pressure regulator) (see
illustration).
(b) One from the union on the inlet manifold’s
left-hand end (see illustration).
(c) The braking system vacuum servo unit
hose - from the inlet manifold (see
Chapter 9 for details).
(d) Also disconnect the vacuum hoses from
the Exhaust Gas Recirculation system
components - one from the EGR valve,
two from the EGR pipe (note that...

inner wing panel, release the engine
wiring loom and refit the power steering
fluid reservoir.
(g) Secure the engine wiring loom neatly to
the engine/transmission so that it cannot
be damaged as the unit is removed from
the vehicle.
14Unbolt both parts of the exhaust manifold
heat shield; unclip the coolant hose to allow
the upper part to be withdrawn.
15Remove the auxiliary drivebelt (see
Chapter 1).
16Unbolt the power steering pump (see
Chapter 10); secure it as far as possible
(without disconnecting...

31Where the vehicle is fitted with manual
transmission, disconnect the driveshafts from
the transmission as follows, referring to
Chapter 8 for further details when required:
(a) Unscrew the nuts securing the right-hand
driveshaft support bearing, and withdraw
the heat shield.
(b) Pull the right-hand driveshaft out of the
transmission; be prepared to catch any
spilt oil.
(c) Secure the driveshaft clear of the
engine/transmission - remember that the
unit is to be lowered out of the vehicle -
and ensure...

socket spanner of suitable size (see
illustrations).
48Once the subframe is aligned as precisely
as possible, tighten its bolts to the specified
torque wrench setting without disturbing its
position. Recheck the alignment once all the
bolts are securely tightened.
49With the subframe aligned and securely
fastened, the engine/transmission unit must
now be positioned precisely, before the
mountings can be reassembled. Ford specify
the use of service tool 21-172; this is a fixture
bolted to the subframe in...

gear linkage heat shield. Reconnect the
gearchange linkage and transmission support
rods to the transmission, adjusting the linkage
using the marks made on removal (see
Chapter 7, Part A, for details).
56Re-install the remaining components and
fasteners in the reverse order of removal.
57Add coolant, engine oil and transmission
fluids as needed (see Chapter 1).
58Run the engine, and check for proper
operation and the absence of leaks. Shut off
the engine, and recheck the fluid levels.
59Remember that,...

2Remove the cylinder head (Part A of this
Chapter, Section 14).
3Using a valve spring compressor, compress
each valve spring in turn until the split collets
can be removed. A special valve spring
compressor will be required, to reach into the
deep wells in the cylinder head without risk of
damaging the hydraulic tappet bores; such
compressors are now widely available from
most good motor accessory shops. Release
the compressor, and lift off the spring upper
seat and spring (see illustrations).
4If, when...

4Scrape off any heavy carbon deposits that
may have formed on the valves, then use a
power-operated wire brush to remove
deposits from the valve heads and stems.
Inspection
Note:Be sure to perform all the following
inspection procedures before concluding that
the services of a machine shop or engine
overhaul specialist are required. Make a list of
all items that require attention.
Cylinder head
5Inspect the head very carefully for cracks,
evidence of coolant leakage, and other
damage. If cracks are...

grinding or head resurfacing. Use
compressed air, if available, to blow out all the
oil holes and passages.
2Beginning at one end of the head, lubricate
and install the first valve. Apply molybdenum
disulphide-based grease or clean engine oil to
the valve stem, and refit the valve. Where the
original valves are being re-used, ensure that
each is refitted in its original guide. If new
valves are being fitted, insert them into the
locations to which they have been ground.
3Fit the plastic protector...

remove the piston/connecting rod assemblies
may result in piston ring breakage.
7Slacken each of the big-end bearing cap
bolts half a turn at a time, until they can be
removed by hand. Remove the No 1 cap and
bearing shell. Don’t drop the shell out of the
cap.
8Remove the upper bearing shell, and push
the connecting rod/piston assembly out
through the top of the engine. Use a wooden
hammer handle to push on the connecting
rod’s bearing recess. If resistance is felt,
double-check that all of the ridge...

applicable); note that Ford state that the
piston-cooling oil jets (where fitted) must be
renewed whenever the engine is dismantled
for full overhaul (see illustrations).
2Remove the main bearing caps, and
separate the bearing shells from the caps and
the cylinder block/crankcase. Mark or label
the shells, indicating which bearing they were
removed from, and whether they were in the
cap or the block, then set them aside (see
illustration). Wipe clean the block and cap
bearing recesses, and inspect them...
