ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: 8HX 8HW 8HZ
B1EP18GC
Setting the timing.
Remove the upper timing cover (1).
Rotate the engine by means of the crankshaft screw (2).
NOTE:The pegging hole is located under the crankshaft bearing cap cover.
Peg the engine flywheel, using tool
[3].
Remove the lower timing cover (3).
Uncouple the exhaust line from the manifold.
IMPERATIVE: Uncouple the exhaust line in order to avoid damaging the front flexible pipe. Twisting,
pulling and bending the front flexible pipe reduces its life.
Remove:
The engine speed sensor (6).
The belt retaining stop (5).
The screw (2).
The crankshaft pinion (4)(with its magnetic track «a»).
IMPERATIVE: The magnetic track should show no signs of damage and should not be approached
by any other source of magnetism.Should this not be adhered to,it is essential to replace the crank
shaft pinion.
Refit the screw (2).

Setting the timing (continued).
Turn the tensioner roller to the right to bring the index «c»to position «d», using a
hexagonal spanner.
Tighten the screw
(9)of the tensioner roller, tighten to 3 ± 0,3 m.daN.
Remove the tools [4]and [5].
Rotate the engine
ten times(check that the timing pinion is correctly up against the
crankshaft).
Check:
The pegging of the camshaft.
The crankshaft pinion.
The fuel high pressure pump pinion
(15).
The correct positioning of the index of the dynamic tensioner.
If these are not correct, repeat the operation to position the timing belt.Refit:
The engine speed sensor
(6).
The belt retaining stop (5), tighten to 0,7 m.daN.

ALL TYPES FILLING AND BLEEDING THE COOLING CIRCUIT
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.
Top up the system to the max. mark, with the engine cold.

SAFETY REQUIREMENTS.
Preamble.
All interventions on the injection system must be carried out to conform with the following requirements and regulations:
Competent health authorities.
Accident prevention.
Environmental protection.
WARNING:Repairs must be carried out by specialised personnel informed of the safety requirements and of the precautions to be taken.
Safety requirements.
IMPERATIVE: Take into account the very high pressures in the high pressure fuel circuit (1350 bars), and respect the requirements below: No smoking in proximity to the high pressure circuit when work is being carried out.
Avoid working close to flame or sparks.
Engine running: Do not work on the high pressure fuel circuit.
Always stay clear of the trajectory of any possible jet of fuel, which could cause serious injuries.
Do not place your hand close to any leak in the high pressure fuel circuit.
After the engine has stopped, wait
30 secondsbefore any intervention.
NOTE:This waiting time is necessary in order to allow the high pressure fuel circuit to return to atmospheric pressure.

ADJUSTING THE MECHANICAL CONTROLS OF THE DELPHI INJECTION PUMP
Engine: WJY
Adjusting the fast idle.
Engine cold.
Ensure that the lever (2)is up against its stop to the right.
If not, adjust the tension of the cable (3)using the cable clamp (1).
Finish tensioning using the sleeve tensioner (4).
Engine hot. Check that the cable (3)is in tension.
Checking the thermostatic sensor. There should be a minimum 6 mmcable travel between a cold and a hot engine.
Adjusting the accelerator control.
Prior conditions.
Engine hot (cooling fan is engaged twice).
Checking the accelerator cable tension. Fully depress the accelerator pedal.
Check that the lever (6)is against its stop (5)otherwise, alter the position of the pin.
If not, adjust the position of the accelerator cable tensioning retaining pin.
Ensure that in the idle position the lever
(6)is against the stop (7).

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.
