5.4 Engine Maintenance for Long-term Storage
5.4.1 Preparing the Engine for Long-term Storage
In the case of a long-term storage that lasts longer than two months, to prevent the interior
parts of the engine and some components of the injection system from oxidizing, prepare the
engine as follows:

Drain the lubricant oil from the sump after heating the engine.

Pour protective oil type 30/M into the engine up to the "minimum" level indicated on the oil
level dipstick. Start the engine and run it for about 5 minutes.

Drain the fuel from the injection circuit, from the filter and from the injection pump chan-
nels.

Connect the fuel circuit to a tank containing protective liquid and introduce the liquid by
pressurizing the circuit and driving the engine for about 2 minutes, after executing the
operation of the injection system. The required operation may be completed by directly
polarizing terminal 50 of the electric starter motor with positive voltage equal to that of the
nominal system voltage, using the specifically provided conductor.

Spray the protective oil 30/M in a quantity of about 10g per liter of displacement in the
turbocharger intake inlet, during the engine turning operation described in the previous
paragraph.

Close all of the engine's intake, discharge, and ventilation and bleeder holes with plugs or
seal them with adhesive tape.

Drain the residual 30/M protective oil from the sump, which can be used for an additional
2 preparations.

Place warning notices of ENGINE WITHOUT OIL on the engine and dashboard.

Drain the coolant if it was not mixed if necessary with antifreeze and corrosion inhibitors,
positioning signs that this operation was performed.
In the case of prolonged inactivity, repeat these operations every 6 months, according to the
following procedure:

Drain the 30/M protective oil from the sump.

Repeat the operations from point 2
nd
to point 7

.
To protect the external parts of the engine, spray the protective liquid on the unpainted metal
parts such as the flywheel, pulleys, etc., and do not spray it on belts, connector cables and
electrical equipment.
