REFITTING
The alignment of the sub-frame with the body
will be made easier by positioning two threaded
rods Mot. 1233-01 in the two front mountings of
the sub-frame on the body.
Tighten the sub-frame mounting bolts to a torque
of:
- 6.2 daN.m at the front,
-10.5 daN.m at the rear.
Refitting is the reverse of removal.
Fit the heat shields correctly.
Apply
Loctite FRENBLOC to the caliper mounting
bolts and tighten them to the recommended tor-
que.
Press the brake pedal several times to bring the
pistons into contact with the brake pads.
Fill:
- the engine and gearbox with oil, if necessary,
- the cooling circuit and bleed it (see section 19
"Filling - bleeding"). F8Q engine
Fix tool Mot. 1040-01 underneath the sub-frame.

Lower the lift until the tool touches the ground.
Remove the sub-frame mounting bolts and take
out the engine and transmission assembly by lif-
ting the body.
NOTE : for any operation requiring separation of
the engine, gearbox and sub-frame assembly,
take care to mark the position of Mot. 1159 on the
sub-frame.
Remove the mounting bolts (3).

MEASURING THE THICKNESS OF THE CYLINDER
HEAD GASKET
Checking piston protrusion
Clean the piston heads in order to eliminate any
traces of deposits.
Turn the crankshaft in its operating direction
once, to bring piston n° 1 close to
TDC .
Fit tool Mot. 252-01 on the piston.
Fit tool Mot. 251-01, complete with dial gauge
Mot. 252-01. on the plate Ensure that the dial
gauge measuring pin is in contact with the cylin-
der block; then locate the piston
TDC.
NOTE
: All measurements are to be carried out in
the longitudinal axis of the engine, in order to eli-
minate any errors due to tilting of the piston.
99173R
Measure the piston protrusion.
ONLY TAKE INTO CONSIDERATION THE
DIMENSIONS OF THE PISTON WITH THE
GREATEST PROTRUSION.
For a maximum piston protrusion:
- lower than 0.868 mm, use a gasket marked by
a tab with two holes ,
- included between 0.868 mm and 1mm, use a
gasket marked by a tab with one hole,
- greater than 1mm, use a gasket marked by a
tab with three holes. F8Q Engine

DIESEL EQUIPMENT
Adjusting idle speed
13
12870R
It is vital to make these adjustments when the en-
gine is warm, and after the engine cooling fan
has operated at least twice.
The idle speed adjustment and anti-stalling
function adjustment must be carried out
correctly, since these operations directly
influence the behaviour of the engine at idle
speed and in the deceleration phase (hesitation
idle speed lasts too long, etc.).
1 Idle speed adjustment screw
2 Load lever
3 Residual flow adjustment screw (anti-stalling
function)
4 Fast idle lever
5 Idle speed cable grip
FAST IDLE SPEED
Without applying a vacuum to the LDA, position
the cable grip (5) at 2 ± 1 mm from the fast idle
speed lever (4).
NOTE : the fast idle speed value is not directly ad-
justable; it is adjusted on the injection unit.
CHECKING THE MAXIMUM SPEED
Whilst the engine is warm, accelerate to full load ;
the engine speed must be between 4 500 and
4 700 rpm (this adjustment can only be carried
out in a Renault Injection Centre workshop).
IDLE SPEED AND RESIDUAL FLOW ADJUSTMENT
(anti-stalling)
a)Ensure that the fast idle speed function is not
operational .
b)Adjust the idle speed to 825 ± 25 rpm. using
screw (1).
c)Place a 4 mm shim between the load lever (2)
and the residual flow screw (3).
d)Adjust the engine speed to 1 250 ± 50 rpm.
using the residual flow screw (3).
e)Remove the 4 mm shim then accelerate
sharply twice.
f)Check the conformity of the idle speed; if
necessary, repeat the idle speed adjustment
and check the residual flow once more.

INJECTION
Coolant temperature management
244Injection coolant temperature sensor and
coolant temperature indication on
instrument panel.
3 track sensor, of which two tracks are
allocated to the injection coolant
temperature information, and one to the
indication of the coolant temperature on
the instrument panel.
259Warning coolant temperature switch for
instrument panel.
Operating principle
Sensor 244 allows :
- the coolant temperature to be shown on the
instrument panel,
- the injection computer to receive constant in-
formation on the engine coolant temperature
.
The injection computer, depending on the co-
olant temperature, controls :
- the injection system,
- the cooling fan assembly.
The engine cooling fan assembly is controlled
at fast speed (both slow and fast speeds are
controlled by the air conditioning system) if
the temperature is greater than 99°C. If the
temperature falls below 96°C, it cuts off
automatically ( if a check has to be carried out,
ensure that the air conditioning is not opera-
tional).
