Tests and checks

!

Check that the cooling fluid does not contain filth
before using it; if it does, filter with appropriate net
filters; in case of filling-ups, see the table REFUELING
in the section “GENERAL”.

Start the engine, leave it in motion at a running rate
little more than the minimum and wait that the
cooling fluid temperature reaches the rate for the
thermostat to be opened , then check that:

Assemble injectors as described in the appropriate chapter.

Assemble high and low pressure tubing as described in the
paragraph “main service operations to be performed on
engine fitted on vehicle”.

- Check manifold, cooling fluid and air-conveyor

conditions and replace them in case of damage;

- Fasten the screw to the prescribed torque;

- Fill the cooling system with cooling fluid and bleed as

described before.
