2. Open the radiator expansion tank plug.
3. Disconnect water pump inlet and outlet hoses and allow the coolant to drain out.
4. Unscrew the taps placed under the radiators and accessible when the rear aprons are removed in order to
empty the rear radiators.
5. Connect all the removed parts, close the open taps; top up with the prescribed coolant through the radiator

Fuel pump
The two fuel pumps are supplied by a relay controlled by LIE control unit. For safety reasons the pump relevant to
cylinder bank 1-6 is controlled by LIE control unit of cylinder bank 7-12 and vice versa. They are roller type positive displacement pumps with permanent magnet energizing.

Any operating point of the engine is found by two parameters: • Rotation Speed;
• Engine Load.
Having found these parameters through relevant processing, it is possible to calculate and obtain the injection (delivered fuel amount and relevant timing in relation to bursting TDC), the ignition (correct spark advance) and any
other function for each engine operating point.
The rotation speed is measured directly through the relevant sensor.
The engine load is determined indirectly trough a “density” parameter (representing the engine load) according to
the absolute pressure in the intake manifold and the intake air temperature.
The engine load is continuously detected from the LIEs and elaborated according to the user’s requirements (accelerator pedal): through the &$1line the /,(Vsend the signal to the ETBs that control the throttle bodies
allowing the air in the intake manifold to reach a determined density (engine load).

speed-load parameter pairs, the time/ injection timing values and ignition spark advance required for correct engine
operation are stored.
These injection time values are further corrected according to the signal coming from the oxygen sensor that, based RQFHUWDLQRSHUDWLRQVWUDWHJLHVGHWHUPLQHVDFRQWLQXRXVÀXFWXDWLRQRIWKHPL[WXUHVWUHQJWKDURXQGDWDUJHWYDOXH

by these three parameters.
All operation situations that require special adaptation of the calculated time/injection timing values, spark advance
and throttle bodies position are managed by the engine control unit, correcting the calculated base values through
suitable strategies according to the signals coming from the system sensors.

Injection System
The aim of the injection management strategies is to supply the engine with the correct amount of fuel at the required
moment according to the engine operating conditions.
The injection management is essentially the calculation of the injection time, the determination of the injection timingand the subsequent actuation through the injector control.
The “basic” injection time is calculated by a mathematical interpolation of the speed-load map: The values contained

The ratio below is the mixture titration and is indicated with the Greek letter ë (lambda): Quantity of air taken in by the engine

Theoretical quantity of air to burn - All the injected fuel
The stoichiometric ratio depends on the type of fuel: For current unleaded petrol it is equivalent to approx. 14.7, that corresponds to a lambda titration = 1.
