N.B.: Do not use oils or greases while fixing thecooling system. Failure to observe this
regulation can cause irreversibledeformation to the sealing gaskets.
.
.
- Check the proper circuit sealing when it is in pressure and at the temperature.
- For a more accurate check, wait until the system has cooled down since small leaks may not
be visible due to evaporation.
- The water pump is provided with a drainage
hole in case of leaks from the cooling system
mechanical seal, or from the shaft sealing oil
guard.
- If cooling fluid or oil leaks are detected, inspect the pump (see
[1005]?Flywheel cover
?/span>
hapter).
1
- Check the system outside seals as described above.
YES
go to 2
NO
go to 3
2
- Check the head gasket seal (see "Thermal unit and timing system" chapter)
- If water leaks are detected in the engine oil, inspect the pad on the head cooling circuit.
3
-
Fix any damaged seals.
1
- Oil into the cooling fluid.
YES

2
- Check the head gasket seal (see "Thermal unit and timing system" chapter).
1
- Check the expansion tank cap efficiency.
N.B.: The cap is provided with an overpressure valve calibrated at 0.9 bar.
There is also a valve that must allow air inlet during the cooling step.
YES

NO
go to 3
2
- Check the head gasket seal (see "Thermal unit and timing system" chapter)
3
- Replace the cap.
