COOLING - EXHAUST - TANK
The heating radiator has no valve.
The fluid circ ulation is permanently done in the heating radiator, this leading to t he engine
cooling.
FILLING
Open the purging screw located on the water pipe between engine and climate control radiator.
Fill up the circuit by the expansion vessel hole
Tighten the purging screws in the moment when the fluid is flowing in a continuos jet.
Start the engine, maintaining it at 2500 rot/min.
Adjust the fluid level in the expansion vessel, during about 4 minutes.
Close the cap of the expansion vessel.
PURGING
Let the engine run for 10 minutes at 2500 rot/min, until engine fan starting (necessary
period for automatic gas purge).
Check if the fluid level in the expansion vessel is nearby the mark “Max”.
Do not open the purging screws with the engine running.
Ret ighten the expansion vessel cap with the warm e ngine.

SPECIAL TOOLS

MS 5 54-06 Adapter fo r M.S. 554-07
MS 5 54-07 Kit for checking the coo ling system sealing
1. CIRCUIT S EALIN G CHECKING
Mount the adapter M.S 554 –01 instead of
the expansion vessel valve.
Connect a t the adapter, the M.S. 554-07
device. Wa rm the engine, then stop it.
P ump, in order to create pressure in the cir-
cuit. Stop pumping at a value lower with 0.1 bar
then the valve calibrating value ( 1.2 bar)
The pressure must not drop, if not, check for
leak and fix it.
Progressively unscrew the device connection
for cooling circuit decompressing , then unscrew
the device, and mount back the expansion vessel
valve.
2. CHECKING ALVE CALIBRATION
M ount t he expansion vessel va lve on
adapter M.S. 554-06 and connect it to the
MS 557-07 device.
P ump to increase the pressure, this must
be stabilized at the valve calibration value 1.2
w ith a checking tolerance of ± 0.1 bar.
The calibra tion value of t he expansion
vessel valve is : 1.2 bar.
