Maintenance procedures
1 General information
1 This Chapter is designed to help the home
mechanic maintain his/her vehicle for safety,
economy, long life and peak performance.
2 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.
3 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.
4 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.
5 The first step in this maintenance
programme 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.
2 Intensive maintenance
1 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.
2 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.
3 If engine wear is suspected, a compression
test (refer to the relevant Part of Chapter 2) 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 the
performance of the engine, and may prove a
waste of time and money, unless extensive
overhaul work (Chapter 2B) is carried out first.
4 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 8)
b) Check all the engine-related fluids
(Section 3).
c) Check the condition and tension of the
auxiliary drivebelt (Section 22).
d) Renew the spark plugs (Section 25).
e) Inspect the distributor cap, rotor arm and
HT leads - as applicable (Chapter 5B).
f) Check the condition of the air cleaner filter
element, and renew if necessary (Section
33).
g) Renew the fuel filter (Section 36).
h) Check the condition of all hoses, and
check for fluid leaks (Section 21).
i) Check the idle speed and mixture settings
- as applicable (Chapter 4A).
5 If the above operations do not prove fully
effective, carry out the following secondary
operations:
Secondary operations
a) Check the charging system (Chapter 5A).
b) Check the ignition system (Chapter 5B).
c) Check the fuel system (Chapter 4).
d) Renew the distributor cap and rotor arm -
as applicable (Chapter 5B).
f) Renew the ignition HT leads - as
applicable (Chapter 5B).
Weekly Checks 1•5
3.3a Removing the engine oil filler cap
Weekly checks
Engine oil
1 The engine oil level is checked with a
dipstick that extends through the dipstick/oil
filler tube on the rear of the cylinder block and
into the sump at the bottom of the engine.
Depress and turn the cap anti-clockwise to
remove it. The dipstick is attached to the cap.
2 The oil level should be checked with the
vehicle standing on level ground with the
engine still warm, between 2 and 5 minutes
after the engine has been switched off.
3 Release the oil filler cap and withdraw the
dipstick from the tube, then wipe all the oil
from the end with a clean rag or paper towel.
Insert the clean dipstick back into the tube as
far as it will go, then withdraw it once more,
Note the oil level on the end of the dipstick.
Add oil as necessary until the level is on the
upper ("MAX") mark on the dipstick (see
illustrations). Note that 1.0 litre of oil will be
required to raise the level from the lower
MIN") mark to the upper mark.
4 Always maintain the level between the two
dipstick marks. If the level is allowed to fall
below the lower mark, oil starvation may result,
which could lead to severe engine damage. If
the engine is overfilled by adding too much oil,
this may result in oil leaks or oil seal failures.
3.3b Markings on the engine oil level
dipstick
5 Oil is added via the dipstick/filler cap on the
rear of the engine, behind the inlet manifold.
Remove the filler cap and dipstick completely
before topping-up the oil level. Always use the
correct grade and type of oil as shown in
"Lubricants, fluids and capacities".
Coolant
Warning: DO NOT attempt to
remove the expansion tank
, pressure cap when the engine is
hot, as there is a very great risk of
scalding.
6 All vehicles covered by this manual have a
pressurised cooling system. An expansion
tank is incorporated in cooling system, and is
located on the right-hand side of the engine
compartment. As engine temperature
increases, the coolant expands, and the level
in the expansion tank rises. As the engine
cools, the coolant level drops. Circulation of
coolant through the expansion tank occurs at
all times that the engine is running, and in this
way, any accumulation of air in any part of the
engine is purged continually.
7 The coolant level in the expansion tank should
be checked regularly. The level in the tank varies
with the temperature of the engine. When the
engine is cold, the coolant level should be on or
slightly below the "MAX" mark on the side of the
tank. When the engine is hot, the level may rise
slightly above the "MAX" mark.
8 If topping-up is necessary, wait until the
engine is cold, then unscrew the pressure cap on
3.3c Topping-up the engine oil level
the expansion tank one or two turns. Wait until
any pressure remaining in the system is released,
then fully unscrew the cap and remove it.
9 Add a mixture of water and antifreeze (see
Section 35) through the expansion tank filler
neck until the coolant is on the "MAX" mark on
the side of the tank (see illustrations). Refit
the cap, and tighten it clockwise as far as it
will go to secure.
10 With a sealed type cooling system like
this, the addition of coolant should only be
necessary at very infrequent intervals. If
frequent topping-up is required, it is likely
there is a leak in the system. Check the
radiator, all hoses and joint faces for any sign
of staining or actual wetness, and rectify as
necessary. If no leaks can be found, it is
advisable to have the pressure cap and the
entire system pressure-tested by a dealer or
suitably-equipped garage, as this will often
show up a small leak not previously apparent.
Brake and clutch fluid
1 The brake and clutch fluid reservoir is
mounted on the left-hand side of the engine
compartment, behind the battery. The "MAX"
and "MIN" marks are indicated on the side of the
reservoir (see illustrations), and the fluid level
