Cylinder head gasket
Mount the MOT 484 device or MOT
588 clamps for jackets maintenance.
Check the cylinder head smoothness using
a lineal a nd a set of templates. The maximal admissible deformation: 0.05
mm. The cylinder head is not to be rectified!REMOU NT I NG
Clean the gasket-seating surface of the cyl-
inder head.
Mount the cylinder head with a new gasket.
Perform the dismounting operation s in the re-
verse order.
Tighten the cylinder head observing the cyl-
inder head tightening method described in chap-
ter 10 “Dismounting-Remounting” .
Mount the distribution belt ( see chapter 11
”Distribution belt”).
Adjust the tilters.
Perform the cooling circuit filling and purging
(see chapter 19 “ Filling and Purging” ).
REMARK:
At each operation implying battery dis-
mounting,
when reconnecting it, introduce the radio
code t hat is written on the vehicle-purchas-
ing invoice.

PURPOSE
To avoid the fire hazard due to the fuel losses, that may occur in case of an accident.
OPERATION
The hazard sensor ( 1) is placed in the engine compartment, being mounted on the left shock
absorber column.
In case of shock, the sensor ball l eaves its lodgement, t hus interrupting the electric c ircuit
between the control relay of the petrol electric fuel pump and the electric petrol pump.
HAZARD SENSOR RE-STARTING
The upper part of the hazard sensor is to be pushed to re-position the ball i nto its lodgement
and thus to re-start the sensor.
