The maintenance intervals in this manual are provided with the
assumption that you will be carrying out the work yourself. These are
the minimum maintenance intervals recommended by the manufacturer
for vehicles driven daily. If you wish to keep your vehicle in peak
condition at all times, you may wish to perform some of these
procedures more often. We encourage frequent maintenance, because
it enhances the efficiency, performance and resale value of your vehicle.
If the vehicle is driven in dusty areas, used to tow a trailer, or drivenfrequently at slow speeds (idling in traffic) or on short journeys, more
frequent maintenance intervals are recommended.
When the vehicle is new, it should be serviced by a factory-
authorised dealer service department, in order to preserve the factory
warranty.

1•6Maintenance Procedures
This Chapter is designed to help the home
mechanic maintain his/her vehicle for safety,
economy, long life and peak performance.
The Chapter contains a master maintenance
schedule, followed by Sections dealing
specifically with each task in the schedule.
Visual checks, adjustments, component
renewal and other helpful items are included.
Refer to the accompanying illustrations of the
engine compartment and the underside of the
vehicle for the locations of the various
components.
Servicing your vehicle in accordance with
the mileage/time maintenance schedule and
the following Sections will provide a planned
maintenance programme, which should result
in a long and reliable service life. This is a
comprehensive plan, so maintaining some
items but not others at the specified service
intervals, will not produce the same results.
As you service your vehicle, you will
discover that many of the procedures can -
and should - be grouped together, because of
the particular procedure being performed, or
because of the close proximity of two
otherwise-unrelated components to one
another. For example, if the vehicle is raised
for any reason, the exhaust can be inspected
at the same time as the suspension and
steering components.
The first step in this maintenanceprogramme is to prepare yourself before the
actual work begins. Read through all the
Sections relevant to the work to be carried out,
then make a list and gather together all the
parts and tools required. If a problem is
encountered, seek advice from a parts
specialist, or a dealer service department.
If, from the time the vehicle is new, the
routine maintenance schedule is followed
closely, and frequent checks are made of fluid
levels and high-wear items, as suggested
throughout this manual, the engine will be kept
in relatively good running condition, and the
need for additional work will be minimised.
It is possible that there will be times when
the engine is running poorly due to the lack of
regular maintenance. This is even more likely if
a used vehicle, which has not received regular
and frequent maintenance checks, is
purchased. In such cases, additional work
may need to be carried out, outside of the
regular maintenance intervals.
If engine wear is suspected, a compression
test will provide valuable information regarding
the overall performance of the main internal
components. Such a test can be used as a
basis to decide on the extent of the work to be
carried out. If, for example, a compression test
indicates serious internal engine wear,
conventional maintenance as described in this
Chapter will not greatly improve theperformance of the engine, and may prove a
waste of time and money, unless extensive
overhaul work is carried out first.
The following series of operations are those
most often required to improve the
performance of a generally poor-running
engine:
Primary operations
a)Clean, inspect and test the battery
(Section 6)
b)Check all the engine-related fluids
(Section 3).
c)Check the condition and tension of the
auxiliary drivebelt (Section 21).
d)Renew the spark plugs (Section 20).
e)Inspect the distributor cap, rotor arm and
HT leads - as applicable (Chapter 5).
f)Check the condition of the air cleaner filter
element, and renew if necessary (Section 38).
g)Renew the fuel filter (Section 41).
h)Check the condition of all hoses, and
check for fluid leaks (Section 10).
i)Check the idle speed and mixture settings
- as applicable (Chapter 4).
If the above operations do not prove fully
effective, carry out the following secondary
operations:
Secondary operations
a)Check the charging system (Chapter 5).
b)Check the ignition system (Chapter 5).
c)Check the fuel system (Chapter 4).
d)Renew the distributor cap and rotor arm -
as applicable (Chapter 5).
f)Renew the ignition HT leads - as
applicable (Chapter 5).
2Intensive maintenance
1Introduction
Engine oil
1Check the oil level as follows.
2With the vehicle parked on level ground,
and with the engine having been stopped for a
few minutes, open and prop the bonnet.
Withdraw the dipstick, wipe it on a clean ragand re-insert it fully. Withdraw it again and
read the oil level relative to the marks on the
end of the stick (see illustration).
3The oil level should be in between the MAX
and MIN marks on the dipstick. If it is at or
below the MIN mark, top-up (via the oil filler
cap) without delay. The quantity of oil required
to raise the lever from MIN to MAX on the
dipstick is approximately 1 litre. Do not overfill
(see illustration).
4The rate of oil consumption depends onleaks and on the quantity of oil burnt. External
leakage should be obvious. Oil which is burnt
may enter the combustion chambers through
the valve guides or past the piston rings;
excessive blow-by past the rings can also
force oil out via the crankcase ventilation
system. Driving conditions also affect oil
consumption.
5Always use the correct grade and type of oil
as shown in “Lubricants and fluids”.
Coolant
6Check the coolant level as follows.
7Open and prop the bonnet. Observe the
level of coolant through the translucent walls
of the expansion tank (on the right-hand side
of the engine bay). The level should be up to
the MAX mark when the engine is cold, and
may be somewhat above the mark when hot.
8If topping-up is necessary, wait for the
system to cool down if it is hot. Place a thick
rag over the expansion tank cap and slacken it
3Fluid level checks
3.2 Dipstick markings3.3 Topping up the engine oil
Warning: DO NOT remove the
expansion tank pressure cap
when the engine is hot, as there
is a great risk of scalding.
Weekly checks
procarmanuals.com

The exhaust system fitted in production is
made of aluminised steel, with stainless steel
used in the endplates and baffles of the rear
silencer. Individual sections of the system are
easily renewed in service.
Emission control for the UK market is
achieved largely by the inherent efficiency of
the fuel, ignition and engine management
systems. A welcome spin-off from such
efficiency is remarkably good fuel economy for
a vehicle of such size and weight.
Precautions
Fuel
Many of the procedures in this Chapter
require the removal of fuel lines and
connections which may result in some fuel
spillage. Residual pressure in fuel-injection
systems will remain in the fuel lines long after
the vehicle was last used, therefore extra care
must be taken when disconnecting a fuel line
hose. Loosen any fuel hose slowly to avoid a
sudden release of pressure which may cause
fuel spray. As an added precaution place a rag
over each union as it is disconnected to catch
any fuel which is forcibly expelled. Before
carrying out any operation on the fuel system
refer to the precautions given in “Safety first!”
at the beginning of this Manual and follow
them implicitly. Petrol is a highly dangerous
and volatile liquid and the precautions
necessary when handling it cannot be
overstressed
Tamperproof adjustment screws
Certain adjustment points in the fuel system
(and elsewhere) are protected by tamperproof
caps, plugs or seals. The purpose of such
tamperproofing is to discourage, and to deter,
adjustment by unqualified operators.
In some EU countries (though not yet in the
UK) it is an offence to drive a vehicle with
missing or broken tamperproof seals. Before
disturbing a tamperproof seal, satisfy yourself
that you will not be breaking local or national
anti-pollution regulations by doing so. Fit a
new seal when adjustment is complete when
this is required by law.
Do not break tamperproof seals on a vehicle
which is still under warranty.
Catalytic converter
The catalytic converter is a reliable and
simple device which needs no maintenance in
itself, but there are some facts of which an
owner should be aware if the converter is to
function properly for the full service life.
a)DO NOT use leaded petrol in a car
equipped with a catalytic converter the
lead will coat the precious metals,
reducing their converting efficiency and
will eventually destroy the converter.
b)Always keep the ignition and fuel systems
well-maintained in accordance with the
manufacturer’s schedule - particularly,
ensure that the air cleaner filter element,
the fuel filter and the spark plugs are
renewed at the correct interval - if the inletair/fuel mixture is allowed to become too
rich due to neglect, the unburned surplus
will enter and burn in the catalytic
converter, overheating the element and
eventually destroying the converter.
c)If the engine develops a misfire, do not
drive the car at all (or at least as little as
possible) until the fault is cured - the
misfire will allow unburned fuel to enter
the converter, which will result in
overheating, as noted above.
d)DO NOT push- or tow-start the car - this
will soak the catalytic converter in
unburned fuel, causing it to overheat when
the engine does start - see b) above.
e)DO NOT switch off the ignition at high
engine speeds - if the ignition is switched
off at anything above idle speed,
unburnedfuel will enter the (very hot)
catalytic converter, with the possible risk
of igniting on the element and damaging
the converter.
f)DO NOT use fuel or engine oil additives -
these may contain substances harmful to
the catalytic converter.
g)DO NOT continue to use the car if the
engine burns oil to the extent of leaving a
visible trail of blue smoke - the unburned
carbon deposits will clog the converter
passages and reduce the efficiency; in
severe cases the element will overheat.
h)Remember that the catalytic converter
operates at very high temperatures -
hence the heat shields on the car’s
underbody and the casing will become hot
enough to ignite combustible materials
which brush against it - DO NOT,
therefore, park the car in dry undergrowth,
over long grass or piles of dead leaves.
i)Remember that the catalytic converter is
FRAGILE, do not strike it with tools during
servicing work, take great care when
working on the exhaust system, ensure
that the converter is well clear of any jacks
or other lifting gear used to raise the car
and do not drive the car over rough
ground, road humps, etc, in such a way as
to “ground” the exhaust system.
j)In some cases, particularly when the car is
new and/or is used for stop/start driving, a
sulphurous smell (like that of rotten eggs)may be noticed from the exhaust. This is
common to many catalytic converter-
equipped cars and seems to be due to the
small amount of sulphur found in some
petrols reacting with hydrogen in the
exhaust to produce hydrogen sulphide
(H
2S) gas; while this gas is toxic, it is not
produced in sufficient amounts to be a
problem. Once the car has covered a few
thousand miles the problem should
disappear - in the meanwhile a change of
driving style or of the brand of petrol used
may effect a solution.
k)The catalytic converter, used on a well-
maintained and well-driven car, should
last for between 50 000 and 100 000 miles
- from this point on, careful checks should
be made at all specified service intervals
of the CO level to ensure that the
converter is still operating efficiently - if
the converter is no longer effective it must
be renewed.
See Chapter 1, Section 38.
1On carburettor models only, the air cleaner
can take in both hot and cold air. Hot air is
obtained from a shroud bolted to the exhaust
manifold.
2A flap valve in the air cleaner spout
determines the mix of hot and cold air. The
valve is operated by a vacuum diaphragm.
Vacuum is obtained from the inlet manifold
and is applied via a heat-sensing valve, which
cuts off the vacuum as the temperature of the
incoming air rises. Thus the air cleaner takes in
only hot air on starting from cold, changing
progressively to cold air as the engine warms
up (see illustrations).
3If the system fails, either the engine will take
a long time to warm up (flap stuck in “cold”
position), or it may run roughly and not
develop full power when warm (flap stuck in
“hot” position). Check it as follows.

The vehicle owner who does his or her own maintenance according
to the recommended service schedules should not have to use this
section of the manual very often. Modern component reliability is such
that, provided those items subject to wear or deterioration are
inspected or renewed at the specified intervals, sudden failure is
comparatively rare. Faults do not usually just happen as a result of
sudden failure, but develop over a period of time. Major mechanical
failures in particular are usually preceded by characteristic symptoms
over hundreds or even thousands of miles. Those components which
do occasionally fail without warning are often small and easily carried
in the vehicle.With any fault-finding, the first step is to decide where to begin
investigations. Sometimes this is obvious, but on other occasions, a
little detective work will be necessary. The owner who makes half a
dozen haphazard adjustments or replacements may be successful in
curing a fault (or its symptoms), but will be none the wiser if the fault
recurs, and ultimately may have spent more time and money than was
necessary. A calm and logical approach will be found to be more
satisfactory in the long run. Always take into account any warning
signs or abnormalities that may have been noticed in the period
preceding the fault - power loss, high or low gauge readings, unusual
smells, etc - and remember that failure of components such as fuses or
