En gine  OilCHECK & TOP-UP
Check the oil level at least every 250 miles 
(400 km), when the engine is COLD and with 
the vehicle resting on level ground.
NOTE: If it is necessary to check the oil level 
when the engine is hot, switch off the engine 
and let the vehicle stand for five minutes to 
allow the oil to drain back into the sump. DO 
NOT start the engine.
As a general guide, if the level on the dipstick:
•is nearer to the upper mark than the lower, 
add no oil.
•is nearer to the lower mark than the upper, 
add half a quart of oil. 
•is below the lower mark, add one quart of oil 
and re-check the level after a further five 
minutes.
Oil specification
It is essential to use an oil suitable for the 
climatic conditions in which the vehicle is to be 
operated. Precise specifications are shown in 
‘LUBRICANTS AND FLUIDS’, page 271. If in 
doubt, contact your Land Rover retailer.
Topping-up
1.Withdraw the dipstick and wipe the blade 
clean.
2.Fully re-insert the dipstick and withdraw 
again to check the level, which should 
NEVER be allowed to fall below the lower 
mark on the dipstick.
3.To top-up, unscrew the oil filler cap and 
add oil to maintain the level between the 
UPPER and LOWER marks on the dipstick.
DO NOT OVERFILL!
Oil levels above the MAX mark may cause 
engine damage. Some oil must be removed 
from the engine by a service technician.

DRAIN & REFILL
Ensure that the engine oil is changed at the 
recommended service intervals as specified in 
the Passport to Service book.
NOTE: Under severe operating conditions 
(i.e. regular use in muddy terrain or dusty 
conditions), the engine oil must be changed 
more frequently, even to the extent of a daily 
change. Consult your Land Rover retailer for 
guidance.
Used engine oil
WARNING
Prolonged contact with used engine oil can 
cause serious skin disorders, including 
dermatitis and cancer of the skin. Wear 
protective clothing if possible and ALWAYS 
wash thoroughly after contact.
It is illegal to pollute drains, water courses 
or soil with toxic chemicals such as used 
engine oil. Use authorised waste disposal sites 
to dispose of used oil and toxic chemicals.
It is assumed that the engine oil filter will be 
renewed at the same time as draining and 
refilling the engine oil.
Because any used engine oil remaining in the 
filter container will drain into the sump when 
the filter is changed, it is better to change the 
filter element (see ‘Oil filter renewal’, page 203) 
before draining and refilling the engine oil.Drain
With the engine warm (to assist oil drainage) 
and the vehicle parked on firm, level ground, 
remove the filler cap and position a container of 
suitable size (at least 10 US quarts or 10 litres) 
under the drain plug, in the bottom of the sump.

Remove the drain plug and copper washer and 
allow the engine oil to drain into the container.
WARNING
Oil from the engine can be very hot, to avoid 
harmful burns, take care when removing the 
drain plug.Refill
Clean the oil drain plug and its mating surface 
on the engine sump. Fit the drain plug, 
complete with a new copper washer, and 
tighten to 13 lbf.ft (17 Nm).
Refill the engine with fresh oil, suitable for the 
climatic conditions in which the vehicle is to be 
operated (see ‘LUBRICANTS AND FLUIDS’, 
page 271).
DO NOT overfill the engine! Remember that a 
little oil will always remain in the engine after 
draining and that, therefore, the quantity of oil 
required to refill the engine will be slightly less 
than the full capacity quoted in ‘CAPACITIES’, 
page 272.
After filling, allow a few minutes to elapse 
before checking the level on the dipstick (this 
will allow all the oil to drain into the sump and 
enable a true reading to be obtained). Once the 
correct level of oil is shown on the dipstick, 
replace the filler cap.
Start and run the engine. Do not rev the engine 
until the oil pressure warning light 
extinguishes. Check for oil leaks around the 
drain plug.
Stop the engine, wait a few minutes, then check 
the oil level and top up if necessary.

Oil filter renewal
The engine oil filter is located at the front of the 
engine compartment.
1.Unscrew the filter cap anti-clockwise and 
raise it slightly. The filter element will be 
withdrawn by the cap.
2.Allow a few moments for the engine oil 
retained within the filter body to drain 
away.
3.With a suitable container handy, fully lift 
off the cap and element together and place 
them in the container.
4.Pull the cap from the element and clean it.
5.Clean the inside of the filter body.6.Attach the cap to the new filter element by 
pushing it onto the end of the element.
7.Insert the element into the filter body and 
screw down the cap. Tighten to 18 lbf.ft 
(25 Nm)
8.Start and run the engine. Do not rev the 
engine until the oil pressure warning light 
extinguishes. Check for oil leaks around 
the filter body.
9.Stop the engine, wait a few minutes, then 
check the oil level and top up if necessary.

Air CleanerELEMENT RENEWAL
Renewing the air cleaner element at the 
recommended service intervals (see your 
‘Passport to Service book’) is extremely 
important. However, to maintain optimum 
engine performance under dusty operating 
conditions, more frequent renewal will be 
necessary. Consult your retailer for guidance.
1.Release 2 catches securing the hose to the 
rear of the air cleaner; detach the hose. 
2.Release 4 catches securing the cover to 
the air cleaner body and remove the cover 
to gain access to the element.3.Remove and discard the air cleaner 
element, noting which way up the element 
fits. Before fitting a new element, clean the 
inside of the air cleaner body and cover.
4.Fit the new air cleaner element and cover 
and secure the catches. 
5.Connect the hose to the rear of the air 
cleaner and secure the catches.

Co olin g S ystemCOOLANT CHECK AND TOP-UP
WARNING
NEVER remove the filler cap when the engine 
is hot -escaping steam or scalding water 
could cause serious personal injury.
Unscrew the filler cap slowly, allowing the 
pressure to escape before removing 
completely.
Avoid spilling anti-freeze onto a hot engine - 
a fire may result.
CAUTION: NEVER run the engine without 
coolant.
CAUTION: NEVER top-up with salt water. When 
travelling in territories where the water supply 
contains salt, always ensure that you carry a 
supply of fresh (rain or distilled) water.
NOTE: Anti-freeze will damage painted 
surfaces: Soak up any spillage with an 
absorbent cloth immediately and wash the area 
with a mixture of car shampoo and water.
The coolant level in the expansion tank should 
only be checked and topped-up if low level 
indication is given in the message centre. 
Always check the level WHEN THE SYSTEM IS 
COLD.
If it is necessary to remove the filler cap before 
the system has fully cooled, loosen the cap 
slowly, allowing the air pressure to escape 
gradually.Top-up with a 50% mixture of anti-freeze and 
water so that the float protrudes slightly from 
the filler neck, in accordance with the 
illustration inset. DO NOT OVERFILL!
Ensure the cap is tightened fully after top-up is 
completed.
If the level has fallen appreciably, suspect 
leakage or overheating and arrange for your 
retailer to examine the vehicle. 
CAUTION: An over-filled expansion tank may 
cause a build-up of pressure and excess fluid 
could be expelled through the filler cap.

ANTI-FREEZE
WARNING
Anti-freeze is poisonous and can be fatal if 
swallowed - keep containers sealed and out 
of the reach of children. If accidental 
consumption is suspected, seek medical 
attention immediately.
Prevent anti-freeze coming in contact with the 
skin or eyes. If this occurs, rinse immediately 
with plenty of water.
Anti-freeze contains important corrosion 
inhibitors. The anti-freeze content of the 
coolant must be maintained at 50% ± 5% all 
year round (not just in cold conditions). To 
ensure that the anti-corrosion properties of the 
coolant are retained, the anti-freeze content 
should be checked once a year and completely 
renewed every 4 years, regardless of distance 
travelled. Failure to do so may cause corrosion 
of the radiator and engine components.
The specific gravity of a 50% anti-freeze 
solution at 68ºF (20°C) is 1.075 and protects 
against frost down to -33ºF (-36°C).Coolant specification
Use ONLY a 50% mix of water and Castrol 
Anti-freeze NF or approved alternative. See 
‘LUBRICANTS AND FLUIDS’, page 271.
In an emergency - and only if this type of 
anti-freeze is unavailable - top-up the cooling 
system with clean water, but be aware of the 
resultant reduction in frost protection. DO NOT 
top-up or refill with conventional anti-freeze 
formulations. If in doubt consult a Land Rover 
retailer.
NOTE: When clean water is added in the event 
of an emergency, the low coolant light will 
illuminate if the water/anti-freeze mix ratio is 
over-diluted. This light will extinguish when the 
ratio of water/anti-freeze is returned to a 50% 
mix. This should be done at the earliest 
opportunity.
