ANTI-FREEZE
PERCENTAGE CONCENTRATION - 50%
PROTECTION - LOWER TEMPERATURE LIMIT
Complete protection
Vehicle may be driven away immediately from cold,
-33°C (-36°F).
Safe limit protection
Coolant in semi-frozen state. Engine may be started
and driven away after warm-up period, -41°C (-42°
F).Lower protection
Prevents frost damage to cylinder head, block and
radiator. Thaw out before starting engine, -47°C (-53°
F).
CAUTION: Anti-freeze content must never
be allowed to fall below 25% (pre 99MY) or
50% (99MY on) otherwise damage to the
engine is liable to occur. Anti-freeze content
should not exceed 60% (all models) as this will
greatly reduce cooling efficiency.

MAINTENANCEREV: 05/99 ADDITIONAL MAINTENANCE SCHEDULES
Camshaft drive belt
The engine timing gears are driven by a toothed
rubber belt which must be renewed at intervals
determined by the severity of operating conditions. In
reasonable, temperate climate operation, the belt
should be renewed every 120,000 km (72,000 miles)
or every six years whichever occurs earlier.
In adverse operating conditions, such as work in dusty
atmospheres, high ambient temperatures, desert and
tropical zones, renew the belt every 60,000 km
(36,000 miles) or every three years, whichever occurs
earlier.
CAUTION: If the drive belt is not renewed
at the correct interval, it could fail,
resulting in serious engine damage.
Oil change diesel engines
If the vehicle is operated on fuel with a high sulphur
content (over 1%) the oil change intervals must not
exceed 5000 km (3000 miles).
Anti-freeze
At two yearly intervals or at the onset of the second
winter, the cooling system should be drained, flushed
and refilled with the required water and anti-freeze
solution.
Hydraulic brake fluid.
It is recommended that at 40,000 km (24,000 miles)
intervals or every two years, whichever is the earlier,
the hydraulic brake fluid should be completely
renewed.
At 80,000 km (48,000 miles) intervals or every four
years, whichever is the earlier, all hydraulic brake fluid
seals and flexible hoses should be renewed. All
working surfaces of the master cylinder and caliper
cylinders should be examined and renewed where
necessary.Air cleaner
When the vehicle is used in dusty or field conditions or
deep wading, frequent attention to the air cleaner may
be required.
Dampers
At 60,000 km (36,000 miles) intervals remove all
suspension dampers, test for correct operation, refit or
renew as necessary.
SPECIAL OPERATING CONDITIONS
When the vehicle is operated in extremely arduous
conditions or on dusty, wet or muddy terrain, more
frequent attention should be paid to all servicing
requirements.
Additional daily or weekly attention depending on
operating conditions:
Check/top-up transfer box oil.
Check steering rubber boots for security and
condition. Renew if damaged.
Check brake fluid level: Investigate cause if any fluid
loss is suspected.
Clean brake discs and calipers.
Lubricate front and rear propeller shaft
universal/sliding joints. Under tropical or severe
conditions, particularly where sand is encountered,
the sliding joints must be lubricated very frequently to
prevent ingress of abrasive material.
Every week and every maintenance inspection check
tyre pressures and inspect tyre treads and side walls.
Under arduous cross-country conditions the tyre
pressures should be checked much more frequently,
even to the extent of a daily check.
Monthly
Renew gearbox oil.
Renew transfer box oil.
Check air cleaner element and renew every 6 months
or as necessary.

REPAIR ENGINE OIL PRESSURE TEST
Service repair no - 12.90.09/01
WARNING: Use suitable exhaust
extraction equipment if an engine test is
being carried out in a workshop.
WARNING: If vehicle has been running,
engine wil be hot; care must be taken
when fitting test equipment to prevent
personal injury.
1.Check that engine lubricant is to correct level.
2.Remove oil pressure switch .
3.Connect pressure test gaugeLRT-12-052A,as
shown.
4.Start and run engine to normal operating
temperature.
5.With engine running at idle check oil pressure,
which should read 1.76 bar (25.87 lbf/in
2).6.If pressure is low it can be caused by the
following:-
Thin or diluted oil.
Low oil in sump.
Choked oil strainer.
Faulty oil pressure relief valve.
Excessively worn or damaged oil pump
displacement gears.
Excessive crankshaft bearing clearance.
7.If excessive pressure is indicated it can be
caused by :-
Overfilling engine with lubricant.
Sticking oil pressure relief valve.
Blockage in breather system.
