E ngine  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 US quart (0.5 liter) of oil. 
•is below the lower mark, add one US quart 
(1 liter) 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 239. If in 
doubt, contact your Land Rover retailer.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!
CAUTION: Oil levels above the MAX mark may 
cause engine damage, in which case some oil 
must be removed from the engine by a service 
technician.

DRAIN & REFILL
Ensure 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.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 6.90 US quarts or 6.60 
liters) 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 24 lbf.ft (33 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 239).
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 240.
CAUTION: Oil levels above the MAX mark may 
cause engine damage, in which case some oil 
must be removed from the engine by a service 
technician.
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
NOTE: To avoid draining the oil pump, it is 
essential that the engine is filled with oil to the 
correct level, before the filter is removed. It is 
therefore recommended that the engine oil is 
renewed before work on the filter commences.
1.Clean the area around the filter head and 
place a suitable container beneath the 
engine.
2.Using a strap spanner, or similar tool, 
unscrew the filter anti-clockwise and 
discard it. 
3.Smear the seal of the new filter with clean 
engine oil, partially fill the filter with oil and 
then screw the filter on clockwise, until it 
is securely is position. Use hand force 
only, DO NOT overtighten.
4.Start and run the engine. Do not rev the 
engine until the oil pressure warning light 
extinguishes. Check for oil leaks around 
the filter and drain plug.
5.Stop the engine, wait a few minutes, then 
check the oil level and top up if necessary.

							Air Cleaner
184
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.
Release the two catches securing the hose to 
the rear of the air cleaner, then detach the hose. 
Release the catches securing the cover to the 
air cleaner body, disengage the two clips at the 
front of the air cleaner and remove the cover to 
gain access to the element.
Remove and discard the air cleaner element. 
Before fitting a new element, clean the inside of 
the air cleaner body and cover.Fit the new air cleaner element and cover and 
secure catches. Ensure the two clips at the front 
of the air cleaner are properly engaged.
Connect the hose to the rear of the air cleaner 
and secure catches.
H2658A
IMPORTANT INFORMATION
Always fit a NEW element; under no 
circumstances should a contaminated 
element be cleaned and used again. 
						

							Spark Plugs
185
S park PlugsSPARK PLUG REMOVE & REFIT
Spark plug removal
Remove the plug leads, ensuring that you hold 
the rubber shroud and NOT the high tension 
leads (this will ensure no damage occurring to 
the connectors during removal).
Ensure that the recesses around the plugs are 
free from debris (to avoid foreign matter 
accidentally entering the cylinder head) and use 
a suitable spark plug wrench to remove the 
plugs and washers.
Refitting the plugs
When refitting, take care not to cross-thread the 
spark plugs, otherwise costly damage to the 
cylinder head will result.
Only fit plugs of a type recommended by the 
vehicle manufacturer (see ‘ENGINES’, 
page 241) and tighten to a torque of 15 lbf.ft 
(20 Nm). Please note that incorrect grades of 
plug may lead to engine failure and serious 
damage.Refitting the high tension (H.T.) leads
To ensure the correct firing order (1, 8, 4, 3, 6, 
5, 7, 2), the high tension leads must be replaced 
in the correct relationship to each other (as 
illustrated). Failure to maintain the correct plug 
lead connections, will result in a misfire and 
possible damage to the catalytic converter.
When pushing the leads onto the plugs, ensure 
that the shrouds are firmly seated on the plugs.

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.
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 
be checked at least weekly (more frequently in 
high mileage or arduous operating conditions). 
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 water and 
approved anti-freeze, see ‘LUBRICANTS AND 
FLUIDS’, page 239, so that the surface of the 
coolant is level with the indicator on the side of 
the tank (arrowed in illustration). 
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. DO NOT 
OVERFILL!

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 30,000 miles (48,000 km) or 
24 months, whichever is the sooner. Failure to 
do so may cause corrosion of the radiator and 
engine components.
The specific gravity of a 50% anti-freeze 
solution at 68°F (20°C) is 1.075 and protects 
against frost down to -33°F (-36°C).
Coolant specification
Use ONLY a 50% mix of water and and an 
approved anti-freeze, see ‘LUBRICANTS AND 
FLUIDS’, page 239.
In an emergency - and only if no approved 
anti-freeze is available - 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.

Brak esBRAKE FLUID
WARNING
Brake fluid is highly toxic - keep containers 
sealed and out of the reach of children. If 
accidental consumption of fluid is suspected, 
seek medical attention immediately.
If brake fluid should come into contact with 
the skin or eyes, rinse immediately with 
plenty of water.
Take care not to spill fluid onto a hot engine - 
a fire may result.
CAUTION: DO NOT drive the vehicle with the 
fluid level below the ‘MIN’ mark.
NOTE: Brake fluid 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.
Check
The fluid level may fall slightly during normal 
use as a result of brake pad wear but should not 
be allowed to fall below the ‘MIN’ mark. Any 
substantial drop in fluid indicates a leak in the       
system, in which case the vehicle must NOT be 
driven and you should contact your retailer.
With the vehicle on level ground, check the fluid 
level at least every week (more frequently in 
high mileage or arduous operating conditions). 
Check the level visually through the side of the 
transparent reservoir without removing the 
filler cap.Top-up
Wipe the filler cap clean before removing to 
prevent dirt from entering the reservoir. 
Unscrew the cap (1/8 turn) and top-up the 
reservoir to the ‘MAX’ mark using brake fluid 
conforming to DOT 4 specification. If this is not 
available, use a universal brake fluid or any 
brake fluid having a minimum boiling point of 
500 ºF (260 ºC) and complying with FMVSS 116 
DOT4.
Use only new fluid from an airtight container 
(old fluid from opened containers or fluid 
previously bled from the system will have 
absorbed moisture, which will adversely affect 
performance, and must NOT be used). DO NOT 
OVERFILL!
Brake fluid must be completely renewed every 
30,000 miles (48,000 km) or 24 months, 
whichever is the sooner.
In addition, note the advice contained under 
‘Brake fluid/component replacement’, 
page 175.
IMPORTANT INFORMATION
Contact your retailer immediately if brake 
pedal travel is unusually long or if there is 
any appreciable drop in brake fluid level.

Power SteeringPOWER STEERING FLUID
WARNING
Power steering fluid is highly toxic and can be 
fatal if swallowed - keep containers sealed 
and out of reach of children. If accidental 
consumption of fluid is suspected, seek 
medical attention immediately.
If power steering fluid should come into 
contact with the skin or eyes, rinse 
immediately with plenty of water.
Do not spill power steering fluid onto a hot 
engine - a fire may result.
NOTE: Power steering fluid 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.
Emergency operation
Any large or sudden drop in the fluid level must 
be investigated by a qualified retailer.
If it can be established that fluid loss is slow, 
then the reservoir may be topped-up to the 
upper level mark to enable the vehicle to be 
driven to the nearest qualified retailer for 
examination. 
CAUTION: If the fluid level has dropped below 
the lower level mark, top-up the reservoir 
before starting the engine, or damage to the 
steering pump could result, see ‘LUBRICANTS 
AND FLUIDS’, page 239.Check and Top-up
Check and top-up the fluid level ONLY with the 
engine switched off and the system cold, and 
ensure that the steering wheel is not turned 
after stopping the engine.
Check the fluid level against the level marks on 
the side of the reservoir. If more fluid is needed, 
first wipe the filler cap clean to prevent dirt from 
entering the reservoir, then twist the cap a 
quarter turn anti-clockwise and pull to remove. 
Top up the reservoir until the fluid reaches the 
upper level mark. DO NOT OVERFILL!
