CHECKING CANISTER BLEED OPERATION
Incorrect operation of the system may cause the
idle speed to be unstable or the engine to stall.
Check the conformity of the circuit (see
operational diagrams)
Be sure to check that the pipe marked "CAN" on
the solenoid valve is correctly connected to the
canister.
Check the condition of the pipes to the fuel tank.

2Canister bleed solenoid valve
3Canister
4Fuel tankAt idle speed connect a pressure gauge
(- 3 ; +3 bars) (Mot. 1311-01) to the "CAN" outlet
on the solenoid valve, to check there is no vacuum
(the command value read by the
XR25 for #23 re-
mains minimal X = 0.7 % ). Is there a vacuum ?
YESIgnition off, use a vacuum pump to apply a
vacuum of 500 mbars to the solenoid valve
at (C). This should not vary by more than 10
mbars in 30 seconds.
Does the pressure vary?
YESThe solenoid valve is faulty. Renew it. Air
must be blown into the pipe (A) connecting
the solenoid valve to the canister to remove
any particles of active carbon.
NOThere is an electrical fault. Check the circuit.
NOUnder bleeding conditions (not at idle
speed, engine warm), the vacuum should
increase (the value for #23 on the XR25
should also be seen to increase).

CHECKING
To ensure the correct operation of the
antipollution system, it is important to keep the
oil vapour rebreathing system clean and in good
working condition.

REFITTING
The sealing of the water pump is carried out using
the product
LOCTITE 518; the bead (H) must be
applied following the diagram below.
REMOVAL
Place the vehicle on a two post lift.
Disconnect the battery.
Drain the cooling circuit from the lower radiator
hose.
Remove:
- the timing belt (see method described in
section 11 "Timing belt),
- the timing tension wheel,
- the water pump, and extract this from above.
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.
