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.

COOLING - EXHAUST - TANKRadiator
* For the vehicles with air conditioning :
- Connect the t wo pipes to the condenser.
- Connect the engine fan resistance connector (1) and the engine fan connector, then attach
it by clips. Connect the battery.
Attach in clips the oil reservoir for power steering and the air inlet pipe on the battery screen.
Perform the cooling circuit filling and purging.
Perform the air conditioning circuit filling with refrigerant fluid HFC 134a (0.600 Kg) and
check for refrigerant fluid leak ( for vehicles with air conditioning).

Cooling engine fan for vehicles without air conditioning
DISMOUNTIN G
Disconnect the battery (-) terminal.
Remove the air inlet pipe from the attachment of the battery screen.
Detach from clips the oil reservoir of the power steering from the battery screen.
Disconnect the engine fan connector ( 1) and detach from clips wiring of point ( 2)
Dismount the four attachment screws ( 3) of the engine fan on radiator.
Carefully dismount the engine fan assembly from guiding points (4).
REMOUNTING
Check the condition of the fan impeller and of the engine fan electric motor.
Carefully position the engine fan assembly in the guiding points (4).
Mount the attachment screws ( 3) of the assembly on the radiator.
Connect the engine fan connector ( 1).
Attach in clips the wiring in point ( 2).
Attach in clips the power steering oil reservoir on the battery screen.
Mount the air inlet pipe.
Connect t he battery (-) terminal. In case the vehicle is equipped with programmable
r adio-cassettes player, e lectronic clock, etc, there are t o be re-programmed before returning
the vehicle to the client.
Check the engine fan operation: start the vehicle engine and disconnect the water
temperature sensor. The engine fan must start. Reconnect the water temperature sensor
then by means of the CLIP tester erase the memorized failure corresponding to the water
temperature sensor.

Check fuse F01 from engine compartment. Is it good?
Replace water temperature sensor.
Replace the control relay of the cooling engine fan.
Replace the cooling engine fan assembly . Start the vehicle’s
engine.
Disconnect the water

cooling engine fan working?
Check the control relay of the cooling engine fan Is it good?
Is any voltage between pins 1
and 2 of the cooling engine fan connector?
The wirin g

damaged. Fix it. Stop the vehicle engine.
Check the continuity and resistance
against vehicle mass between:
- pin B2 connector of water temperature sensor pin 13 UCE i njection;
- pin B1 connector of water temperature sensor pin 73 UCE i njection;
- pin 3 connector of cooling engine fan control relay exit fuse F01;
- pin 5 connector of cooling engine fan control relay pin 2 connector of
cooling engine fan
- pin 1 connector of cooling engine fan vehicle mass;
- pin 1 connector of cooling engine fan control relay pin D 5 connector
of actuators relay;
- pin 2 connector of cooling engine fan control relay pin 8 UCE injection.

C HECKING METHOD
“ DISK RELEASE “
The checking is to be performed at idling, with warm engine. - release the clutch,
- wait for thre e seconds,
- engage the reverse dri ving (engagement must be performed without noise).
CHECKING METHOD
“ CLUTCH RELEASING FORK STROKE “
By means of a lineal perform the following operations:
- measure the distance between the fork upper part and the clutch cable support, in the
clutched position;
- measure the distance be tween t he fork upper part and c lutch cable support, in t he
clutch releasing position;
- calculate the differe nce between the t wo values (the fork active stroke) and compare i t
with the re ference value ( 29 mm).
