Thermostatic expansion valve
Its function is to reduce the refrigerant fluid
pressure at the evaporator entrance, to a default
value. In this way, the fluid passing through the
evaporator may be suction by the compressor
in a complete gaseous condition.
DISMOUNTING
Drain the refrigerant circuit by means of the
charging station .
Dismou nt :
- attachment nut ( A) of the connection
pipes;
-two attachment screws ( B) of the
expansion valve ( C) on evaporator.
REMOU NT I NG
When remounting, replace the pipes sealing
gaskets. The require d tightening moment for B
screws is of 0,8 daNm.
The required tightening moment for A pipes
attachment nut is of 0,57 daNm
V acuum the unit then perform its filling with
refrigera nt fluid by means of the charging
station. REMARK:
Adj ust m e nt s of t he e xpansi on v al v e
spring are to be pe rform e d only by the
manufacturer.
The expansion valve is not to be
repaired and not adjustable.

ELECTRIC DIAGRAMS
89 - 2
The fuse box from the engine compartment is presented in Chapter 9, that contains information
about its location on the vehicle and the functional purpose of the relays and fuse placed on it.
The functional codes of the wires are detailed explained in Chapter 12. FUNCTIONAL DIAGRAMS INTERPRETATION
The functional diagram information included in Chapter 7 are to be i nterpreted taking i nto
consideration the explanation referring to the following example:
1= vehicle class
2= manufacturing year
3= functional electric diagram denomination
4= equipment differentiation criteria for identifying the functional electric diagram ˙
5= electric connector colour ˝
6= connector graphical representation
7= electric component index number
8= number of the fuse box on which the relay or safety fuse is m ounted
9= safety fuse identification on fuse box
10 = safety fuse value
11 = identification of wiring joints
12 = electric mass identification
13 = electric connection colour between wiring ˝
14 = electric connection identification
15 = electric connection graphical representation
16 = symbol, pages containing functional diagrams
17 = wire function code
18 = wire colour ˝
19 = functional diagram number
OBSERVATION:
1. The area ( 4) specifies the differentiating elements serving to the various functional diagrams
identification, considering the following symbols:
ABCO01 = driver’s airbag
CA = climate maintenance with air conditioning
CHAUFO = climate maintenance without air conditioning
CPE = Electric locking/unlock ing doors control
DA = assisted power steering
E0, E1, E2 = levels of equipment
LV E = front windows electric control
