Dismounting – Remounting
Continue to mount:
- cylinder head cover equipped with a ne w cylinder head gasket, tighten the attachment
sc rews to the required moment of 1 daNm;
- water inlet pipe and the oil dipper guide (with new sealing rings);
- distribution casings;
-cr ankshaft pulley or pulleys; tighten the pulley hub screw to the required moment of 2
daN m, then to 68° ± 6°.
ATTENTION!
If the screw is not properly tighten, this may unloose, which may lead to the oil pump
no n-drive and to the distribution derangement, consequently to engine damaging.
- intake manifold and exhaust manifold, tighten the attachmen t screws to the required mo-
ment of 2.5 daNm;
- compressor and/or power steering support;
- alternator (see chapter 16”Alternator”);
- compressor- for vehicles equipped with air conditioning (see chapter 62 “Air condition-
ing”); -power steering pump-for vehicles equipped with power steering (see chapter 36 “Power
steering pump”);
-belt or accessories belt according to the method described in chapter 07” Accessories

PRESENTATION
The system is composed of : -electronic control unit (UCE injection);
-a double ignition coil;
-f our spark plugs;
- spark plugs cables.
OPERATING PRINCIPLE
Subject to the information received from different sensors, but mainly subject to engine RPM
and charge, the electronic control unit will establish the advance at ignition, will identify the cylinders
being at upper dead point and consequently , will control the corresponding coil to them.
This is producing the spark at the level of the two cylinders being at upper de ad point,
interrupting the mass connection of the corresponding coil.

IGNITION COIL
The system is including a double coil (X), controlled by the electronic control unit (UCE).
The coil has and electric connector (Y) with four ways, and is simultaneously producing sparks at cylinders
1 and 4, when it is controlled by the pin 32 of the UCE injection and at cylinders 2 and 3, when it is controlled
by the pin 1 of the UCE injection.

WATER TEMPERATURE SENSOR
The water temperature sensor ( 1) is sending to UCE injection the information regarding water tempera-
tu re, and another information is sent to the indicator from the instrument panel, which will show the water
tem perature.
In case of an alert regarding the water temperature, UCE injection will control the lightening of
the water temperature indicator from the instrument panel.
Subject to water temperature, UCE injection will control:
- injection system;
- relays for controlling the engine cooling fan.
When setting the contact on, the water temperature indicator located on the instrument panel,
will be lighted for 3 seconds, then it will turn off.

If after the contact is set off, in the next 2 minutes from engine stopping, the water temperature
is reaching 102 °C, and t hen the injection computer i s control ling t he starting of the e ngine
cooling fan at low speed. When the temperature is lowering at 95°C, the engine cooling fan stopping will be controlled;
its operation must not exceed 10 minutes after engine stopping.
