Engine coolant Use Texaco XLC long life coolant. Use one part anti-freeze to one part water for
protection down to -36°C (-33°F).
IMPORTANT: Coolant solution must not fall below 50% anti-freeze otherwise
damage to engine is liable to occur. Maximun concentration is 60%.

Compressor Oil ND-OIL 8
LUBRICATION PRACTICE
Use a high quality oil of the correct viscosity range and service classification in the engine during maintenance and
when topping up. The use of oil not to the correct specification can lead to high oil and fuel consumption and
ultimately to damaged components.
Oil to the correct specification contains additives which disperse the corrosive acids formed by combustion and
prevent the formation of sludge which can block the oilways. Additional oil additives should not be used. Always
adhere to the recommended servicing intervals.
WARNING: Many liquids and other substances used in motor vehicles are poisonous. They must
not be consumed and must be kept away from open wounds. These substances, among others,
include anti-freeze, windscreen washer additives, lubricants and various adhesives.

MAINTENANCE BATTERY CONDITION - Td5
Remove
1.Remove drivers seat base.
2.Release clip securing battery cover.
3.Remove battery cover.
NOTE: The vehicle may be fitted with an
alarm and immobilisation system. To
prevent the alarm from sounding, it is
important that the following procedure is used
when disconnecting the battery.
4.Turn the ignition switch to position’II’, and then
to position’0’.
5.Remove the ignition key.
6.Disconnect the vehicle -ve terminal within 15
seconds.
NOTE: Always disconnect the -ve terminal
first. When replacing, connect the +ve
terminal first.
Check
The battery fitted to Td5 models is designed to be
maintenance free, so topping-up is not possible. On
the top of the battery is a battery indicator. When the
indicator shows:
GREEN - The battery is in a good state of charge.
DARK (turning to black) - The battery needs
charging.
CLEAR (or light yellow) - The battery needs
replacing. Do not charge the battery or jump start
the vehicle in this condition.
If the green dot is missing, the battery needs
charging.
NOTE: If the indicator shows clear or
yellow, tap the indicator with the handle of
a screwdriver to disperse any air bubbles.
If the indicator colour remains unchanged, the
battery will need replacing.

7.Clean and grease battery terminals and leads
with petroleum jelly.
8.Connect leads to battery (+ve first) and tighten
clamp bolts.
9.Fit battery cover and secure with clip.

Repair.ROAD TEST
There are two purposes for conducting a road test.
Firstly, to ensure the work completed within the
dealership meets the standards required as layed
down by dealership processes. Secondly, for a skilled
technician to assess the general condition of the
vehicle and report any conditions that the customer
should be made aware of.
CAUTION: Two wheel roller tests must not
be carried out. Four wheel roller tests
must be restricted to 3 mph (5 kph).
1.Check for correct operation of starter switch.
Ensure the engine starts in a correct manner.
Leave the engine running.
2.With vehicle stationary, turn steering from lock to
lock. Check for smooth operation and ensure
there is no undue noise from the power steering
pump or drive belt.
3.Depress clutch and select all gears in turn.
Check for smooth notch free engagement.
4.Drive vehicle on a short road test. Check all
vehicle systems for correct operation. Pay
particular attention to:
Engine noise
Gearbox noise
Suspension noise
Body noise
Braking system operation
Gear selection
Engine performance
5.Check for correct operation of all instruments
and warning devices where practical.
6.After road test, carry out a final inspection of the
vehicle on vehicle ramps.
7.Check all underbonnet fluid levels and top-up if
necessary.

DESCRIPTION AND OPERATION GENERAL
The Td5 diesel engine is a 2.5 litre, 5 cylinder, in-line direct injection unit having 2 valves per cylinder, operated by
a single overhead camshaft. The engine emissions on pre EU3 models comply with ECD2 (European Commission
Directive) legislative requirements. EU3 models comply with ECD3 legislative requirements. Both units employ
electronic engine management control, positive crankcase ventilation and exhaust gas recirculation to limit the
emission of pollutants. The unit is water cooled and turbo-charged and is controlled by an electronic engine
management system.
The cylinder block is a monobloc cast iron construction with an aluminium stiffening plate fitted to the bottom of the
cylinder block to improve lower structure rigidity. The cylinder head and sump are cast aluminium. An acoustic
cover is fitted over the upper engine to reduce engine generated noise.
The engine utilises the following features:
Electronic Unit Injectors (EUI’s)controlled by an Engine Management System for precise fuel delivery under
all prevailing operating conditions.
Turbochargingwhich delivers compressed air to the combustion chambers via an intercooler for improved
power output.
