5.12 Product preservation
Important
• If the engines are not to be used for 6 months, they must be protected by carrying out the
operations described in Engine storage (up to 6 months) (Par. 5.13).
• If the engine is still not in use after the first 6 months, it is necessary to carry out a further operation
to extend the protection period (more than 6 months) (Par. 5.14).
• If the engine is not to be used for an extended period, the protective treatment procedure must be
repeated within 24 months of the previous one.
5.13 Engine storage up to 6 months
Before storing the engine check that:
•
The environments are not humid or exposed to bad weather. Cover the engine with a proper
protective sheet against dampness and atmospheric contaminants.
•
The place is not near electric panel.
•
Avoid storing the engine in direct contact with the ground.
5.14 Engine storage over 6 months
Follow the steps described in Par. 5.13.
1. Engine oil replacement (Par. 6.1).
2. Refuel with fuel additives for long storage.
3. With expansion tank:
make sure that the coolant is up to the maximum level.
4. Without expansion tank:
Top liquid up until the pipes inside the radiator are covered by about 5 mm.
Do not overfill the radiator, but leave room for the fuel to expand.
5. Start the engine and keep it idle at minimum speed for 2 minutes.
6. Bring the engine to 3/4 of the maximum speed for 5÷10 minutes.
7. Turn off the engine.
8. Completely empty the fuel tank.
9. Spray SAE 10W-40 on the exhaust and intake manifolds.
10. Seal the exhaust and intake ducts to prevent foreign bodies from entering.
11. When cleaning the engine, if using a pressure washer or steam cleaning device, avoid directing the
nozzle on electrical components, cable connections and sealed rings (oil seals etc).
If cleaning engine with a pressure washer or steam cleaner, it is important to maintain a minimum
distance of at least 200mm between the surface to be washed and the nozzle - avoiding absolutely
electrical components such as alternators, starter motors and engine control units (ECU).
12. Treat non-painted parts with protective products.
If the engine protection is performed according to the suggestions indicated no corrosion damage should
occur.
