COOLING
Filling and bleeding
19
There is no heater matrix water control valve.
Water flow is continuous in the heater matrix,
which contributes to the cooling of the engine.
FILLING
Check the tightening of the drain plug(s).
Open the two bleed screws.
Fill the circuit through the opening in the expan-
sion bottle.
Tighten the bleed screws as soon as the liquid
flows in a continuous jet.
Start the engine (2 500 rpm).
Adjust the level by overflow for a period of about
4 minutes .
Close the bottle.
BLEEDING
Allow the engine to run for about 10 minutes at
2 500 rpm, until the fan(s) operate (time necessary
for automatic degassing).
Check the liquid level is at the "Maximum" mar-
ker.
DO NOT OPEN THE BLEED SCREWS WHILST THE
ENGINE IS TURNING.
RE-TIGHTEN THE EXPANSION BOTTLE CAP WHILST
THE ENGINE IS WARM.

1 - Testing the sealing of the circuit
Replace the expansion bottle valve with adapter
M.S. 554-01.
Connect this to tool M.S. 554-07.
Let the engine warm up then turn it off.
Pump to put the circuit under pressure.
Stop pumping at 0.1 bar less than the valve is
rated.
The pressure should not drop, otherwise look for
the leak.
Slowly unscrew the union of tool M.S. 554-07 to
decompress the cooling circuit, then remove tool
M.S. 554-01 and refit the expansion bottle valve
with a new seal.2 - Checking the rating of the valve.
If liquid passes through the expansion bottle
valve,the valve must be replaced.
On pump M.S. 554-07 fit tool M.S. 554-06 and fit
the assembly on the valve to be checked.
Increase the pressure which should stabilise at the
valve rating pressure with a test tolerance of
±
0.1 bar.

CLEANING
It is very important not to scratch the gasket faces
of all aluminium components.
Use the product Décapjoint to dissolve the part
of the gasket which remains attached.
Apply the product to the part to be cleaned, wait
approximately 10 minutes, then remove it using a
wooden spatula.
The wearing of gloves is recommended during
this operation.

Special notes
Sealing of the water pump is carried out using
RHODORSEAL 5661, the bead (J) must be applied
following the illustration below.
Apply a bead of
LOCTITE 518 on the sealing sur-
face (L) between the inlet pipe elbow and the wa-
ter pump.
