Engine - Oil Leaks
NOTE: Before installing new gaskets or seals, make
sure that the fault is clearly established.
If the oil leak cannot be identified clearly by a visual
inspection, carry out an ultraviolet
(UV) test:
Ultraviolet (UV) Testing
1. Clean the engine and transmission with a
suitable cleaning fluid.
2. Pour the UV-test fluid in accordance with the
quantity specified by the manufacturer through
the oil filler neck into the engine and install the
oil filler cap.
A WARN1NG:Vehicles with manual transaxle,
shift the transaxle into Neutral. Failure to
follow this instruction may result in
personal injury.
3. Start the engine and let it run for about five
minutes. 4.
Switch off the engine.
N0TE:lf no leak can be found, road test the vehicle
under various loads and check the engine for leaks
again.
5. Check the engine for oil leaks using a suitable
UV lamp.
'
6. Rectify any leaks found and check the engine
for oil leaks.
Measure the compression pressure
N0TE:The powertrain control module (PCM)
receives an error message when the fuel pump
relay is removed or electrical components are
disconnected. This error message must be deleted
from the fault memory using WDS after completing
the compression test.
(' ,
'I N0TE:Valve clearance must be set correctly before
performing a compression test. Make sure the
engine is at the normal operating temperature.

Principles of Operation
Ethanol equipped vehicles
Ethanol, is derived from cellulose waste. A large
proportion of Ethanol is distilled from corn, wheat
and sugar cane crops. The product that is to be
used in this vehicle is called Ethanol E85. E85 is
a mixture of 15% gasoline and 85% Ethanol.
Ethanol is a clear liquid and when fully burnt the
combustion gasses remaining are Carbon Dioxide
and water. This makes the use of Ethanol a good
environmental proposition. One drawback with pure
Ethanol is that it is corrosive to certain rubber and
plastic materials. The
introduction of Ethanol E85 has required some
major internal changes to the fuel supply and
delivery system. Some earlier vehicles used an
Ethanol mixture called Ethanol
El 5. This fuel was
made up of 15% Ethanol and 85% gasoline. At this
mixture ratio, no changes to the fuel charging or
delivery system where required, as no degradation
would occur with the cylinder head valves or
material content of the components, although some
performance loss would be noticeable.
The components used by vehicles running Ethanol
appear to be the same in construction as those
that use unleaded fuel only. The changes are
mainly to do with the materials used and increases
in fuel flow rates.
Ethanol has a much higher octane rating than
standard fuel which means that the ignition and
fuel injection calibrations for a vehicle that is
capable of using Ethanol E85 must be adapted
suitably.

The fuel supply for all petrol fueled variants is
equipped with a return-less fuel system. This
means that the fuel delivery pressure at the fuel
injectors, is monitored and controlled by the fuel
tank module. This control is achived by switching
the fuel pump on and off.
The fuel pump module for both the Ethanol E85

E85 variant is sealed. This is not the only
differance, both fuel pump modules have different
(
Fuel composition monitoring fuel level sensor resistor card values.
The quantity of Ethanol E85 in relation to the
quantity of unleaded fuel contained in the fuel tank
at any one time is not monitored at the fuel tank.
The Ethanol percentage volume can only decrease
from its maximum 85% (pure Ethanol
E85), to zero
(1 00% unleaded fuel).
The fuel charging system compensates for the
changes in fuel composition using the signal
received by the power train control module (PCM)
from the
H02s. The PCM adapts the fueling and
ignition calibrations to suit the current fuel tank
content composition.
Cold start
To overcome the problems relating to cold start
inherent with Ethanol E85 vehicles (temperatures
down to -29 degrees centigrade), a block heater
has been installed into the engine coolant system.
The block heater is located to the rear of the engine
under the exhaust manifold. The block heater is
fitted with a dedicated harness which terminates at an external plug connector fitted into the radiator
grill.
