Tools.
[1]
Filling cylinder: 4520T
[2]Adaptor for filling cylinder: 4222T
IMPERATIVE: Respect the safety and cleanliness requirements.
The draining and refilling operations can be carried out using WINN’S or similar coolant fluid replacement
equipment;it is essential to follow the instructions as stated for that equipment.
Filling and bleeding.
Fit the cylinder adaptor [2] 4222T (Picasso,C2,C3)and the filling cylinder [1] 4520T (all types).
Use the coolant to ensure protection between 15°C and 37°C.
Slowly fill the system.
NOTE:Keep the cylinder filled up (visible level).
Close each bleed screw as soon as the coolant flows without air bubbles.
Start the engine :Engine speed
1500 rpm.
Maintain this speed until the first cooling cycle (cooling fans cut in and cut out).
Stop the engine and allow it to cool down.
Remove the filling cylinder
[1] 4520T (all types)and the cylinder adaptor [2] 4222T.

Peg:
The camshaft hub, using tool [2].
The injection pump hub, using tool [3].
Impossible to peg the camshaft.Reset the valve timing (See page 245).
Possible to peg the camshaft, but not the injection pump.Carry out the following operations:
Loosen the screws of the injection pump hub.
Turn the injection pump hub.
Insert the peg
[3]into the setting hole.
Tighten the screws of the injection pump hub.Tighten to 2,3 ±0,2 m.daN.
ESSENTIAL:If setting the diesel injection pump proves impossible, reset the valve
timing.(See page 251)

ADJUSTING THE MECHANICAL CONTROLS OF THE DELPHI INJECTION PUMP
Engine: WJY (continued)
Adjusting the antistall (residual output).
Insert a 3 mmthick shim (10)between the throttle lever (6)and the antistall screw (7).
Push the stop lever (8).
Insert a 3 mmdiameter peg (9)in the lever (2).
Adjust the engine speed to 1500 rpm ± 100using the stop screw (7).
Remove the shim (10)and the peg (9).
Adjusting the idle speed.
Adjust the speed using the idle adjustment screw (11).
Idling speed:825 ± 25 rpm.
Checking the engine deceleration.
Move the throttle lever (6)to obtain an engine speed of 3000 rpm.
Release the throttle lever (6).
The deceleration should be between 2.5and 3.5seconds.
The drop should be approximately 50 rpmin relation to the idle speed.
Deceleration too fast, (the engine has a tendency to stall)slacken the screw (7)by a quarter turn.
Deceleration too slow, (engine speed is greater than the idle speed)tighten screw (7)by a quarter turn.
NOTE:In each case, check the idle speed for any necessary adjustments.
