COOLING
Filling - bleeding
19
There is no water control valve.
Coolant circulates continuously in the heater
matrix, assisting with engine cooling.
FILLING
The following bleed screws must be opened:
- on the top of the radiator,
- on the heating hose,
- on the thermostat mounting(except E7J- K7M
engines ).
Fill the circuit at the expansion bottle opening.
Close the bleed screws as soon as fluid runs out in
a continuous jet.
Start the engine (2 500 rpm).
Adjust the level by overflow for approximately
4 minutes.
Close the expansion bottle.
BLEEDING
Let the engine run for 20 minutes at
2 500 rpm,until the engine cooling fan operates
(time required for automatic degassing).
Check the fluid level is close to the "Maximum"
mark.
NEVER OPEN THE BLEED SCREWS WHEN THE
ENGINE IS RUNNING.
TIGHTEN THE EXPANSION BOTTLE CAP WHEN THE
ENGINE IS WARM.
