Land Rover Lesson 2 Auto Trans Coolingine Rover Manual

when a range change is selected then the request is
denied and the instrument cluster message centre (if
fitted) will display a SLOW DOWN message.
RANGE CHANGE PROCEDURE
(MANUAL VEHICLES ONLY)
Neutral must be selected on the main transmission
before requesting a range change and then select the
appropriate gear following completion of the range
change. During the range change the driver must not
attempt to move the main transmission out of neutral.
If the lever is moved out of neutral then the range...

GENERAL
The major components of the fuel charging and control
system comprise an intake manifold, a fuel pump, a fuel
rail and six injectors. The fuel pump supplies fuel from
the tank at a constant pressure, via a pipe routed along
the underside of the vehicle, to the fuel rail. The fuel
rail distributes the fuel equally to each of the six
injectors.
INTAKE MANIFOLD
The intake manifold is located on top...

to the correct angle by means of an electric motor
integrated into the throttle body. Sensors in the throttle
body are used to determine the position of the throttle
plate and the rate of change in its angle.

FUEL PRESSURE REGULATOR
The fuel pressure regulator is attached to the RH front
end of the fuel rail. The regulator acts as a damper to
damp pulses from the pump and ensure that the fuel
pressure in the rail and to the injectors is constant. The
regulator is connected by a pipe to the inlet manifold
from which it receives a vacuum to aid the damping
process.
INJECTORS
Six injectors are held between the fuel rails and each
cylinder head. The injectors are sealed to the fuel rail
and cylinder head by O...

GENERAL
The major components of the fuel charging and control
system comprise an intake manifold, a fuel pump, a fuel
rail and eight injectors. The fuel pump supplies fuel
from the tank at a constant pressure, via a pipe routed
along the side of the transmission, to the fuel rail. The
fuel rail distributes the fuel equally to each of the eight
injectors. The fuel injectors, which are controlled by
the Engine Control Module (ECM), are installed in the
fuel rails on each side of the intake manifold. A...

Injectors (8 of)8
Each fuel rail maintains a constant fuel pressure of
4.5bar (65 psi). Four fuel injectors are installed in each
injector housing and are connected to the fuel rail. O
ring seals are used to seal the injectors in the fuel rails
and inlet manifold. A Cooper style fitting is used to
connect the fuel jump hose to the LH fuel rail.
A fuel...

INJECTORS
Eight, top fed, eight hole, fuel injectors are installed in
the fuel rails. Two O rings seal each injector to the
manifold interface and should be renewed whenever an
injector is refitted to an engine. A small amount of
engine oil can be applied to the O rings to aid
installation. No other form of lubrication should be used.
The fuel jets from the injectors are directed onto the
back of the intake valves.
The injectors are electromagnetic solenoid valves
controlled by the ECM. Each injector...
