DISTRIBUTION SYSTEM
MOT 484
Cylinder head gasket
Mount the MOT 484 device or MOT
588 clamps for jackets maintenance.
Check the cylinder head smoothness using
a lineal and a set of templates.
The maximal admissible deformation: 0.05
mm.
The cylinder head is not to be rectified!
REMOUNTING
Clean the gasket-seating surface of the cyl-
inder head.
Mount the cylinder head with a new gasket.
Perform the dismounting operations 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 that is written on the vehicle-purchas-
ing invoice.

(1) The CO value at 2500 rpm must be maximum 0.3 %.
〈 For a water temperature of over 80 ° C and after a steady value of 2500 rpm during 30
sec; after this, return to idle running and perform measurement of polluting emissions level.
The water and air temperature sensors are of CTN type (negative coefficient of temperature)
and their resistance variation subject to the temperature, has the following evolution:
