ks (continued).
Reposition the timing belt, belt at «e»well tensioned, in the following order:
Guide roller
(17).
Camshaft pulley
(16).
Fuel high pressure pump pulley
(15).
Coolant pump pinion
(18).
Tensioner roller
(19).
Remove the
5 mmdiameter peg at «d».
Adjusting the fitting tension of the belt.
Action the tensioner roller (19)to align the marks «f»and «g», avoiding detensioning the timing belt,
with the aid of a male hexagonal spanner, at
«c».
If this is not successful, repeat the operation to tension the belt.Hold the tensioner roller in position
(19).
Tighten the tensioner roller, tightening to
3,7 ±0,3 m.daN.
Check the position of the tensioner roller
(the alignment of the marks «f»and «g»should be correct).
Remove tools
[2]and [3].
Turn the crankshaft
six rotations(clockwise).

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.
