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.

SAFETY REQUIREMENTS: HDi DIRECT INJECTION SYSTEM
Engines: HDi ALL TYPES
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.
