pressing firmly to ensure that the handle is fully seated. With-
draw the dipstick again to inspect the oil level, which should lie between the two dimples on the end of the stick. The oil level
should be maintained at the upper of these two marks in order
to provide optimum engine protection.
Topping Up
: If topping up is necessary, unscrew the oil filler cap
from the left hand end of the cam cover. Add a suitable quantity of the recommended engine oil (see ‘Recommended Lubricants’)
taking care not to spill any oil onto engine or electrical compo
-
nents; use a funnel if necessary. The difference between high and low dipstick marks is equiv
-
alent to 1.6 U.S. quarts (1.5 litre). Allow several minutes for the oil to drain through to the sump before re-checking the oil level.
Do NOT over fill, or lubrication will be degraded and consump
-
tion increased as the oil becomes aerated. Refit the filler cap,
turning clockwise until secure.
Engine Oil Change The use of high quality oil, renewed at the specified intervals,
is the key to engine longevity and sustained performance. Ad
-
here strictly to the engine oil and filter change intervals specified
in the Maintenance Schedule.
For access to the engine sump and filter, the engine bay
undertray must first be removed. This is most easily achieved
with the car raised on a garage hydraulic lift, or alternatively, parked over an inspection pit.
The drain plug is located at the rear of the sump, and should
be removed to drain the sump immediately after a run when
the oil is warm and the impurities are still held in suspension.
On cars fitted with front mounted oil coolers, it is not necessary routinely to attempt to drain the cooler circuit. Servicing & Maintenance

Oil FilterThe canister type oil filter is vertically mounted at the front
of the engine, and is accessible from beneath after removal of
the engine bay undertray. The filter should be renewed along
with the engine oil, at intervals specified in the Maintenance
Schedule.
WARNING:
• Engine oil is hazardous to your health and may be fatal
if swallowed.
• Take all suitable precautions to guard against scalding
from the hot oil.
• Prolonged and repeated contact with used engine oil may cause serious skin disorders, including dermatitis
and cancer.
• Use protective gloves to avoid contact with skin as far
as possible and wash thoroughly after any contact.
• Keep out of reach of children.
Remove the filter by turning in a counterclockwise direction,
if necessary using an oil filter wrench, and dispose of safely
(see ‘Used Engine Oil’). Ensure that only a Lotus specified filter is fitted, as parts with
identical outward appearance can contain different internal
features. Before fitting a new filter, clean the mating face on the engine, and smear the new seal on the filter with clean oil. Add

As a precaution, every week when the engine is completely
COLD, and without disturbing the filler cap, check that the level of coolant in the translucent tank is between the ‘FULL’
and ‘LOW’ marks moulded on the front of the tank. If topping
up is required, wait until the coolant has fully cooled before
turning the cap a quarter turn counterclockwise and allowing any remaining pressure to escape. Only then may the cap be
completely unscrewed. In order to maintain protection from freezing damage and
metal corrosion, use only an approved coolant mixture (see below) to top up the tank to the ‘FULL’ mark. Refit the cap, and
turn clockwise until the leg on the cap locates in the slot at the
front of the tank.
NOTICE: If the cap is removed when the engine is warm, the coolant may boil and a small coolant loss may occur. The com
-
pletely cold header tank level should be checked at the first subsequent opportunity.
Cooling Fans
: Two cooling fans are fitted below the radiator in
the air intake duct. The fans are energised at high coolant tem
-
peratures, or when the air conditioning (if fitted) is selected. The
fans will also run if certain types of engine fault are detected, and
may operate during a 20 minute period following ignition switch off to prevent ‘hot soak’ boiling. An electric coolant circulation pump may also be heard running during this period.
WARNING: Keep hands, tools and clothing away from the radiator
cooling fan area, as personal injury could result from the
fans starting up without warning.
At service intervals, the air duct and matrices of the engine
cooling radiator, a.c. condenser and oil coolers, should be
checked externally for clogging by insects, leaves or other debris,
and if necessary, a water jet used to clear the finning. Take care not to damage or distort the delicate finning of the radiator or
the cooling performance will be degraded.
Anti-Freeze/Corrosion Inhibitor It is most important that the correct coolant specification is
used in order to inhibit boiling and protect the engine and heat

3. If adjustment is required, the clear cover and mask must be removed from the body. From within the wheelarch, remove
the access panel from the wheelarch liner to expose the
headlamp cover retaining screws. Use the hexagonal key provided in the toolkit (in the rear pocket on the batter y
cover) to release the three socket head retaining screws and washers, and withdraw the cover assembly complete
with rubber edge seal from the body. When refitting, do not overtighten the fixings.
4. To adjust the low beam laterally, adjust the dome headed screw at the upper inboard side of the low beam (uppermost)
lamp, accessed from the front of the lamp. Turn clockwise to
adjust the beam to the right. Optimum setting is 0%. To adjust
the vertical aim of the low beam, adjust the dome headed screw at the lower outboard side of the lamp, accessed
from the front of the lamp. Turn clockwise to raise the beam.
Optimum setting is -1.5%.
5. Repeat for the RH lamp. 6. Centralise the machine on the LH high beam (lowermost) lamp, and switch on the high beams. Check the high beam
alignment which should be centralised with the marker dot on
the machine screen or slightly below the horizontal. Optimum
setting is 0%.

Front Turn Indicator Lamp Bulbs For access to the front turn indicator bulb, the lamp unit must
be released from the body. Using a suitable stiff rod or screw

driver blade inserted through the access hole in the outer top
corner of the air intake aperture, press back the lamp retaining
clip at the front end of the lamp, and withdraw the lamp from the body. Twist the bulb holder counterclockwise to release from the
lamp, and replace the bayonet fitting amber bulb. After replacing the bulb and holder, ensure the rubber seal
is correctly positioned around the lamp. Engage the tongue at
the rear end of the lamp unit with the body flange, and press the
front end of the lamp firmly down until a distinct ‘click’ is heard, indicating engagement of the retaining clip. Pull up on the front
end of the lamp to check security.
