1985 FORD GRANADA checking oil

1Work around the vehicle, and lubricate the
hinges and locks with a light machine oil.
2Lightly lubricate the bonnet release
mechanism and exposed sections of inner
cable with a smear of grease.
3Check the security and operation of all
hinges, latches and locks, adjusting them
where required. Where applicable, check the
operation of the central locking system.
4Check the condition and operation of the
tailgate struts, renewing them if either is
leaking or is no longer able to support the
tailgate securely when raised.
SOHC and V6 engines
1The correct functioning of the spark plugs is
vital for the correct running and efficiency of
the engine. It is essential that the plugs fitted
are appropriate for the engine.
2Make sure that the ignition is switched off
before inspecting the HT leads to see if they
carry their cylinder numbers - if not, number
each lead using sticky tape or paint.
3Pull the HT lead connectors off the plugs.
Pull on the connectors, not on the leads.
4Blow away any dirt from around the spark
plug recesses in the cylinder head(s).
5Unscrew and remove the plugs, using a
proprietary plug spanner or a spark plug
socket, extension and ratchet.
6The condition of the plugs will tell much
about the overall condition of the engine. If the
insulator nose of the spark plug is clean and
white, with no deposits, this is indicative of a
weak mixture or too hot a plug (a hot plug
transfers heat away from the electrode slowly,
a cold plug transfers heat away quickly).
7If the tip and insulator nose are covered with
hard black-looking deposits, then this is
indicative that the mixture is too rich. Should
the plug be black and oily, then it is likely that
the engine is fairly worn, as well as the mixture
being too rich.
8If the insulator nose is covered with light tan
to greyish-brown deposits, then the mixture is
correct, and it is likely that the engine is in
good condition.
9Apply a smear of anti-seize compound to
the threads of the new plugs. Make sure that
theinsulators are clean and that the screwed
HT lead adapters are tight. Pay particular
attention to the plug seating surfaces on OHC
engines, since these plugs have no sealing
washers (“taper seat” type) and any dirt will
cause a bad seal.
10Screw each plug into its hole by hand. If a
plug is reluctant to go in, do not force it with a
spanner, but unscrew it and try again. If the
plug is cross-threaded, it is the cylinder head
which will be damaged.11Final tightening of the spark plugs should
ideally be carried out using a torque wrench.
The tightening torques are given in the
Specifications. If a torque wrench is not
available, tighten the plugs beyond the point
where they contact the head as follows:
OHC (taper seat plugs) - One-sixteenth of a
turn maximum
V6 (plugs with washers) - One-quarter of a
turn maximum
12If the taper seat type of plug is
overtightened, the sealing faces will bite
together and removal will be very difficult.
13Refit the HT leads to the plugs, paying
attention to the cylinder numbers. Push each
connector firmly onto its plug.
14Run the engine to verify that the HT leads
have been refitted correctly.
DOHC engines
15Proceed as described above whilst noting
the following points.
a)Remove the air cleaner as described in
Chapter 4.
b)The minimal length of number 3 HT lead
makes removal from the spark plug
difficult. It is advisable to remove this lead
from the distributor prior to removing it
from the spark plug.
c)The spark plugs are deeply recessed in
the cylinder head and it will be necessary
to use a spark plug socket with a long
extension bar. If possible, use a spark plug
socket with a rubber grip inside as this will
hold onto the spark plug once loosened
and will enable the spark plugs to be
withdrawn and refitted more easily.
SOHC and all V6 engines
1All of these engines have one or two
drivebelts which drive the water pump and
alternator from the crankshaft pulley. When
power steering is fitted, the same belts drive
the steering pump. The air conditioning
compressor, when fitted, is driven
independently.
2Periodically inspect the drivebelt(s) for
fraying, cracks, glazing or other damage. Turn
the engine so that the full length of the belt(s)
can be viewed. Renew belts which are in poor
condition. When twin drivebelts are fitted, both
must be renewed together, even if only one is
damaged.
3Check the tension of the drivebelt(s) by
pressing firmly with the fingers in the middle of
the longest belt run (engine stopped). Tension
is correct when the belt can be deflected by
10 mm (0.4 in) under firm finger pressure (see
illustration).
4Renewal and adjustment procedures for
models with power steering are given in
Chapter 11. For other models proceed as
follows.
5Disconnect the battery negative lead.
6On models with air conditioning, remove the
compressor drivebelt.
7Slacken the alternator pivot and adjusting
bolts. Swing the alternator towards the engine
and slip the belt(s) off the pulleys.
8Fit the new belt(s) over the pulleys. Move
the alternator away from the engine until the
belt tension is correct, then tighten the
alternator adjusting strap and pivot bolts. If it
is necessary to lever against the alternator to
achieve the correct tension, only do so using a
wooden or plastic lever(seeillustration).
9Refit and tension the air conditioning
compressor drivebelt, when applicable.
10Reconnect the battery. If a new drivebelt
has been fitted, run the engine for a few
minutes, then stop it and recheck the tension.
11Check the tension of new belts again after
a few hundred miles.

21.3 Checking drivebelt tension
It is very often difficult to insert spark
plugs into their holes without cross-
threading them. To avoid this
possibility, fit a short length of 5/16-
inch internal diameter rubber hose over
the end of the spark plug. The flexible
hose acts as a universal joint to help
align the plug with the plug hole.
Should the plug begin to cross-thread,
the hose will slip on the spark plug,
preventing thread damage to the
aluminium cylinder head. Remove the
rubber hose, and tighten the plug to the
specified torque using the spark plug
socket and a torque wrench. Fit the
remaining spark plugs in the same
manner.

1Remove the radiator grille being careful not
to damage the condenser fins.
2Check the refrigerant charge as follows. The
engine should be cold and the ambient
temperature should be between 18°and 25°C
(64°and 77°F).
3Start the engine and allow it to idle. Observe
the refrigerant sight glass(see illustration)
and have an assistant switch on the air
conditioning to fan speed III. A few bubbles
should be seen in the sight glass as the
system starts up, but all bubbles should
disappear within 10 seconds. Persistent
bubbles, or no bubbles at all, mean that the
refrigerant charge is low. Switch off the
system immediately if the charge is low and do
not use it again until it has been recharged.
4Inspect the refrigerant pipes, hoses and
unions for security and good condition. Refit
the radiator grille.
5The air conditioning system will lose a
proportion of its charge through normal
seepage typically up to 100 g (4 oz) per year -
so it is as well to regard periodic recharging as
a maintenance operation.
1Check the final drive oil level as follows.
2Position the vehicle over a pit, or raise it at
front and rear on ramps or axle stands (see
“Jacking”). The vehicle must be level.
3Wipe clean around the final drive filler/level
plug (see illustration).Unscrew the plug with
a hexagon key. Using a piece of bent wire as
a dipstick, check that the oil is no more than
10 mm (0.4 in) below the plug hole.
4If topping-up is necessary, use clean gear
oil of the specified type. Do not overfill.
Frequent need for topping-up can only be due
to leaks, which should be rectified.
5When the level is correct, refit the filler/level
plug and tighten it.
6There is no requirement for periodic oil
changing, and no drain plug is provided. Lubricate the transmission selector and
kickdown linkages with engine oil or aerosol
lubricant.
1Examine all steering and suspension
components for wear and damage. Pay
particular attention to dust covers and gaiters,
which if renewed promptly when damaged can
save further damage to the component
protected.
2At the same intervals, check the front
suspension lower arm balljoints for wear by
levering up the arms(see illustration).
Balljoint free movement must not exceed
0.5 mm (0.02 in). The track rod end balljoints
can be checked in a similar manner, or by
observing them whilst an assistant rocks the
steering wheel back and forth. If the lower arm
balljoint is worn, the complete lower arm must
be renewed.
3Check the shock absorbers by bouncing the
vehicle up and down at each corner in turn.
When released, it should come to rest within
one complete oscillation. Continued
movement, or squeaking and groaning noises
from the shock absorber suggests that
renewal is required.Position the vehicle over a pit, or raise it at
front and rear on ramps or axle stands.
Examine the driveshaft joint rubber gaiters.
Flex the gaiters by hand and inspect the folds
and clips. Damaged or leaking gaiters must be
renewed without delay to avoid damage
occurring to the joint itself
Check the tightness of the final drive
mounting bolts and the driveshaft flange
screws.
1Except on vehicles with a wax-based
underbody protective coating, have the whole
of the underframe of the vehicle steam-
cleaned, engine compartment included, so
that a thorough inspection can be carried out
to see what minor repairs and renovations are
necessary.
2Steam-cleaning is available at many
garages, and is necessary for the removal of
the accumulation of oily grime, which
sometimes is allowed to become thick in
certain areas. If steam-cleaning facilities are
not available, there are some excellent grease
solvents available which can be brush-applied;
the dirt can then be simply hosed off.
3After cleaning, position the vehicle over a
pit, or raise it at front and rear on ramps or axle
stands.
4Using a strong light, work around the
underside of the vehicle, inspecting it for
corrosion or damage. If either is found, refer to
Chapter 12 for details of repair.
Periodically inspect the rigid brake pipes for
rust and other damage, and the flexible hoses
for cracks, splits or “ballooning”. Have an
assistant depress the brake pedal (ignition on)
and inspect the hose and pipe unions for
leaks. Renew any defective item without delay.
On 2.0 litre engines, good electrical contact
between the carburettor stepper motor
plunger and the adjusting screw is essential to
maintain a regular idle speed.
Clean the plunger and adjusting screw
contact faces with abrasive paper followed by
switch cleaning fluid. Switch cleaning fluid is
available from electronic component shops.

1Remove the sump and cylinder head.
2Check the big-end caps for identification
marks and if necessary use a centre-punch to
identify the caps and connecting rods (see
illustration).
3Turn the crankshaft so that No 1 crankpin is
at its lowest point, then unscrew the nuts and
tap off the cap. Keep the bearing shells in the
cap and connecting rod.4Using the handle of a hammer, push the
piston and connecting rod up the bore and
withdraw from the top of the cylinder block.
Loosely refit the cap to the connecting rod
(see illustration).
5Repeat the procedure in paragraphs 3 and 4
on the No 4 piston and connecting rod, then
turn the crankshaft through half a turn and
repeat the procedure on Nos 2 and 3 pistons
and connecting rods.
1With the engine removed from the vehicle,
remove the pistons and connecting rods as
described in the previous Section. (In fact it is
not necessary to push the pistons out of the
bores if no work is to be done on them.)2Remove the timing belt and crankshaft
sprocket, and the flywheel or driveplate. Also
remove the auxiliary shaft sprocket.
3Unbolt the crankshaft front oil seal housing
and auxiliary shaft front cover and remove the

4Remove the oil pump and strainer.
5Check the main bearing caps for
identification marks and if necessary use a
centre-punch to identify them (see
illustration).
6Before removing the crankshaft check that
the endfloat is within the specified limits by
inserting a feeler blade between the centre
crankshaft web and the thrustwashers (see
illustration). This will indicate whether new
thrustwashers are required or not.

Carburettor models
The crankcase ventilation system consists
of the special oil filter cap (containing a steel
wool filter) and an oil separator and vent valve
on the left-hand side of the engine. This is
connected by hose to the inlet manifold. The
system operates according to the vacuum in
the inlet manifold. Air is drawn through the
filler cap, through the crankcase, and then
together with piston blow-by gasses through
the oil separator and 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.
Fuel-injection models
This system is closed, consisting of an oilseparator on the left-hand side of the engine
and a hose connecting it to the inlet air
trunking. Because the trunking is not subject
to manifold vacuum, no vent valve is needed.
1With the engine completely stripped, clean
all the components and examine them for
wear. Each part should be checked, and
where necessary renewed or renovated as
described in the following Sections. Renew
main and big end shell bearings as a matter of
course, unless you know that they have had
little wear and are in perfect condition.
2If in doubt as to whether to renew a
component which is still just serviceable,
consider the time and effort which will be
incurred should it fail at an early date.
Obviously the age and expected life of the
vehicle must influence the standards applied.
3Gaskets, oil seals and O-rings must all be
renewed as a matter of routine. Flywheel and
cylinder head bolts must be renewed because
of the high stresses to which they are
subjected.
4Take the opportunity to renew the engine
core plugs while they are easily accessible.
Knock out the old plugs with a hammer and
chisel or punch. Clean the plug seats, smear
the new plugs with sealant and tap them
squarely into position.1Unscrew the bolts and remove the oil pump
cover (see illustration).
2Using feeler blades check that the rotor
clearances are within the limits given in
Specifications (see illustrations). If not,
unbolt the pick-up tube and strainer and
obtain a new unit (see illustration).Fit the
pick-up tube and strainer to the new pump
using a new gasket, and tighten the bolts.
3If the oil pump is serviceable refit the cover
and tighten the bolts.
1Examine the bearing surfaces of the
crankshaft for scratches or scoring and, using
a micrometer, check each journal and
crankpin for ovality. Where this is found to be
in excess of 0.0254 mm (0.001 in) the
crankshaft will have to be reground and
undersize bearings fitted.
2Crankshaft regrinding should be carried out
by a suitable engineering works, who will

3Note that undersize bearings may already
have been fitted, either in production or by a
previous repairer. Check the markings on the
backs of the old bearing shells, and if in doubt
take them along when buying new ones(see
illustrations).Production undersizes are also
indicated by paint marks as follows:
White line on main bearing cap - parent bore
0.40 mm oversize
Green line on crankshaft front counterweight
- main bearing journals 0.25 mm undersize
Green spot on counterweight - big-end
bearing journals 0.25 mm undersize
4If the crankshaft endfloat is more than the
maximum specified amount, new
thrustwashers should be fitted to the centre
main bearings. These are usually supplied
together with the main and big-end bearings
on a reground crankshaft.
5An accurate method of determining bearing
wear is by the use of Plastigage. The
crankshaft is located in the main bearings (and
big-end bearings if necessary) and the
Plastigage filament located across the journal
which must be dry. The cap is then fitted and
the bolts/nuts tightened to the specified
torque. On removal of the cap the width of the
filaments is checked against a scale which
shows the bearing running clearance. This
clearance is then compared with that given in
the Specifications (see illustration).
6If the spigot bearing in the rear of the
crankshaft requires renewal extract it with a
suitable puller. Alternatively fill it with heavygrease and use a close fitting metal dowel
driven into the centre of the bearing. Drive the
new bearing into the crankshaft with a soft
metal drift.
1The cylinder bores must be examined for
taper, ovality, scoring and scratches. Start by
examining the top of the bores; if these are
worn, a slight ridge will be found which marks
the top of the piston ring travel. If the wear is
excessive, the engine will have had a high oil
consumption rate accompanied by blue
smoke from the exhaust.
2If available, use an inside dial gauge to
measure the bore diameter just below the
ridge and compare it with the diameter at the
bottom of the bore, which is not subject to
wear. If the difference is more than 0.152 mm
(0.006 in), the cylinders will normally require
reboring with new oversize pistons fitted.
3Proprietary oil control rings can be obtained
for fitting to the existing pistons if it is felt that
the degree of wear does not justify a rebore.
However, any improvement brought about by
such rings may be short-lived.
4If new pistons or piston rings are to be fitted
to old bores, deglaze the bores with abrasive
paper or a “glaze buster” tool. The object is to
produce a light cross-hatch pattern to assist
the new rings to bed in. 5If there is a ridge at the top of the bore and
new piston rings are being fitted, either the top
piston ring must be stepped (“ridge dodger”
pattern) or the ridge must be removed with a
ridge reamer. If the ridge is left, the piston ring
may hit it and break.
6Thoroughly examine the crankcase and
cylinder block for cracks and damage and use
a piece of wire to probe all oilways and
waterways to ensure that they are
unobstructed.
1Examine the pistons for ovality, scoring and
scratches. Check the connecting rods for wear
and damage. The connecting rods carry a
letter indicating their weight class; all the rods
fitted to one engine must be of the same class
(see illustration).
2The gudgeon pins are an interference fit in
the connecting rods, and if new pistons are to
be fitted to the existing connecting rods the
work should be carried out by a Ford garage
who will have the necessary tooling. Note that
the oil splash hole on the connecting rod must
be located on the right-hand side of the piston
(the arrow on the piston crown faces forwards)
(see illustration).
3If new rings are to be fitted to the existing
pistons, expand the old rings over the top of
the pistons. The use of two or three old feeler
blades will be helpful in preventing the rings
dropping into empty grooves. Note that the oil
control ring is in three sections.
4Before fitting the new rings to the pistons,
insert them into the cylinder bore and use a
feeler blade to check that the end gaps are
within the specified limits (see illustrations).
5Clean out the piston ring grooves using a
piece of old piston ring as a scraper. Be
careful not to scratch the aluminium surface of
the pistons. Protect your fingers - piston ring
edges are sharp. Also probe the groove oil
return holes.
6Fit the oil control ring sections with the
spreader ends abutted opposite the front of the
piston. The side ring gaps should be 25 mm

(1.0 in) either side of the spreader gap. Fit the
tapered lower compression ring with the TOP
mark towards the top of the piston and the gap
150°from the spreader gap, then fit the upper
compression ring with the gap 150°on the
other side of the spreader gap. Note that the
compression rings are coated with a
molybdenum skin which must not be damaged.
7Note that the compression rings are made
of cast iron, and will snap if expanded too far.
Examine the surface of the camshaft
journals and lobes and the cam followers for
wear. If excessive, considerable noise would
have been noticed from the top of the engine
and a new camshaft and followers must be
fitted.
Check the camshaft bearings for wear and if
necessary have them renewed by a Ford
garage.
Check the camshaft lubrication tube for
obstructions and make sure that the jet holes
are clear. Obstruction of the holes can be due
to sludge build-up which occurs when regular
oil changes have been neglected.
Examine the auxiliary shaft for wear and
damage and renew it if necessary.
If the auxiliary shaft endfloat is outside the
limits given in the Specifications fit a new
thrust plate. If this does not bring the endfloat
within limits, renew the shaft.
Whenever the timing belt is removed it is
worthwhile renewing it, especially if it has
covered a high mileage. This is more important
on the 2.0 litre engine where stripped teeth on
the timing belt can cause the pistons to foul
the valves.If the ring gear is badly worn or has missing
teeth, it should be renewed. The old ring can
be removed from the flywheel by cutting a
notch between two teeth with a hacksaw and
then splitting it with a cold chisel. Wear eye
protection when doing this.
To fit a new ring gear requires heating the
ring to 204°C (400°F). This can be done by
polishing four equal sections of the gear,
laying it on a suitable heat resistant surface
(such as fire bricks) and heating it evenly with
a blow lamp or torch until the polished areas
turn a light yellow tinge. Do not overheat or the
hard wearing properties will be lost. The gear
has a chamfered inner edge which should go
against the shoulder when put on the flywheel.
When hot enough place the gear in position
quickly, tapping it home if necessary and let it
cool naturally, without quenching.
1This operation will normally only be required
at comparatively high mileages. However, if
persistent pinking occurs and performance
has deteriorated even though the engine
adjustments are correct, decarbonising and
valve grinding may be required.
2With the cylinder head removed, use a
scraper to remove the carbon from the
combustion chambers and ports. Remove all
traces of gasket from the cylinder head
surface, then wash it thoroughly with paraffin.
3Use a straight-edge and feeler blade to
check that the cylinder head surface is not
distorted. If it is, it must be resurfaced by a
suitably equipped engineering works.
4If the engine is still in the car, clean the
piston crowns and cylinder bore upper edges,
but make sure that no carbon drops between
the pistons and bores. To do this, locate two
of the pistons at the top of their bores and seal
off the remaining bores with paper and
masking tape. Press a little grease between
the two pistons and their bores to collect any
carbon dust; this can be wiped away when the
piston is lowered.5Examine the heads of the valves for pitting
and burning, especially the exhaust valve
heads. Renew any valve which is badly burnt.
Examine the valve seats at the same time. If
the pitting is very slight, it can be removed by
grinding the valve heads and seats together
with coarse, then fine, grinding paste.
6Where excessive pitting has occurred, the
valve seats must be recut or renewed by a
suitably equipped engineering works.
7Valve grinding is carried out as follows.
Place the cylinder head upside down on a
bench on blocks of wood.
8Smear a trace of coarse carborundum paste
on the seat face and press a suction grinding
tool onto the valve head. With a semi-rotary
action, grind the valve head to its seat, lifting
the valve occasionally to redistribute the
grinding paste. When a dull matt even surface
is produced on both the valve seat and the
valve, wipe off the paste and repeat the
process with fine carborundum paste as
before. A light spring placed under the valve
head will greatly ease this operation. When a
smooth unbroken ring of light grey matt finish
is produced on both the valve and seat, the
grinding operation is complete.
9Scrape away all carbon from the valve head
and stem, and clean away all traces of
grinding compound. Clean the valves and
seats with a paraffin soaked rag, then wipe
with a clean rag.
10If the guides are worn they will need
reboring for oversize valves or for fitting guide
inserts. The valve seats will also need
recutting to ensure that they are concentric
with the stems. This work should be given to
your Ford dealer or local engineering works.
11If the valve springs have been in use
for 20 000 miles (32 000 km) or more, renew
them. Always renew the valve stem oil seals
when the valves are removed.
1To ensure maximum life with minimum
trouble from a rebuilt engine, not only must
everything be correctly assembled, but it must
also be spotlessly clean. All oilways must be
clear, and locking washers and spring washers
must be fitted where indicated. Oil all bearings
and other working surfaces thoroughly with
engine oil during assembly.
2Before assembly begins, renew any bolts or
studs with damaged threads.
3Gather together a torque wrench, oil can,
clean rag, and a set of engine gaskets and oil
seals, together with a new oil filter.
4If they have been removed, new cylinder
head bolts and flywheel bolts will also be
required.
