CHECKING AND SETTING THE VALVE TIMING
Engines: 8HY 8HV
B1EP18VD
Setting the timing.
Perform the preliminary operations for checking the timing up to removing tool [1]at «a»for immobiling the
engine flywheel.
Refit screw
(8).
Rotate the crankshaft to bring the camshaft towards its pegging point.
Peg the camshaft, using tool
[2](oil the pegs).
WARNING: Do not press or damage the track which is the target for the engine speed sensor (14).
Peg the crankshaft at «b», using tool [3].
Remove:
The timing protector
(13).
The engine speed sensor
(14).
Slacken the screw
(12)of the tensioner roller, keeping it slack with the aid of a hexagonal spanner at
«c».
Detension the belt by pivoting the tensioner roller
(clockwise).
Remove the timing belt, commencing with the coolant pump pinion.
Peg the pulley

Setting the timing (continued).
Chec
king the setting.
IMPERATIVE: Just prior to refitting, carry out the following tests.
Check that:
the rollers and the coolant pump operate freely
(no play and no tight spot).
there are no traces of oil
(from the crankshaft and camshaft sealing rings).
there is no leak of coolant fluid
(from the coolant pump).
the target track of the engine speed sensor
(14)is not damaged or scratched
(if necessary replace the defective components).
Refitting.
Fit the timing belt on the crankshaft pinion.
Position the belt on the guide roller, with the belt well tensioned.
Refit:
The timing protector
(13).
The sensor
(14).

Adjusting the timing belt tension (continued).
IMPERATIVE: Never rotate the engine backwards.WARNING:
Do not touch or damage the track of the target of the engine speed sensor (14).
Peg the crankshaft, using tool
[3].
Check the position of the tensioner roller
(the alignment of the marks «f»and «g»should be correct).
If this is not the case, repeat the operation to tension the belt.Peg the camshaft pulley, using tool
[2].
IMPERATIVE: Should it be impossible to peg the camshaft, check that the offset between the
camshaft hole and the pegging hole is not more than 1 mm. If the offset is too great, repeat theoperation.
Remove the pegs [2]and [3].
Refit tool
[1]at «a».
Remove the screw
(8).
Complete the refitting.

spanner at «d».
Detension the timing belt by pivoting the tensioner roller (clockwise).
Remove the timing belt, starting with the coolant pump pinion.
Checks.
ESSENTIAL: Just prior to refitting, proceed to the checks as below.
Check:
That the rollers and the coolant pump pulley turn freely (without play and without tight
spot).
That there are no signs of oil leaks (at the crankshaft and camshaft seals).
That there are no leaks of coolant fluid(at the coolant pump).
That the track of the engine speed sensor target (15)is not damaged or scratched.
Replace any components that are defective (if necessary).

Adjusting the timing belt tension.
Act on the tensioner roller (18)to align the marks «g»and «h», avoiding detensioning the
timing belt, using an allen spanner at «d».
Should this fail, repeat the operation to tension the timing belt.Hold the tensioner roller
(18).
Tighten the tensioner roller fixing nut to 3,7 ± 0,3 m.daN.
Check the position of the tensioner roller (the alignment of the marks «g»and «h»should
be correct).
Remove tools [2]and [3].
Rotate the crankshaft six times(clockwise).
IMPERATIVE:Never rotate the engine backwards.
WARNING:
Do not touch or damage the track of the target of the engine speed sensor (14).
Peg the crankshaft, using tool
[3].
Check the position of the tensioner roller (the alignment of the marks «g»and «h»should
be correct).
If this is not the case, repeat the operation to tension the timing belt.
Peg the camshaft pulley, using tool
[2].
IMPERATIVE: Should it be impossible to peg the camshaft, check that the offset bet
ween the camshaft hole and the pegging hole is not more than 1 mm. If the offset is
too great, repeat the operation.
Remove tools [2]and [3].

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.
Refit the filler cap.
