LONG TERM STORAGE (MORE THAN 30 DAYS) - Continued
Prepare the engine for long-term storage as follows:
Drain and thoroughly flush the cooling system with clean, soft water.
Refill the cooling system with clean, soft water.
Add a rust inhibitor to the cooling system.
Remove, check, and recondition the injectors, if necessary, to ensure they will be ready to operate when the
engine is restored to service.
Reinstall the injectors in the engine, time them, and adjust the valve clearance.
Circulate the coolant through the entire system by operating the engine until normal operating temperature is
reached (160 to 185°F [71 to 85°C]).
Stop the engine.
Remove the drain plug and completely drain the engine crankcase. Reinstall and tighten the drain plug.
Install new lubricating oil filter to elements and gaskets.
Fill the crankcase to the proper level with a 30-weight preservative lubricating oil.
Drain the engine fuel tank.
Refill the fuel tank with enough rust-preventive fuel oil to enable the engine to operate 10 minutes.
Drain the fuel filter and strainer. Remove the retaining bolts, shells, and elements. Discard the used elements
and gaskets. Wash the shells in clean fuel oil and insert new elements. Fill the cavity between the element
and shell about two-thirds full of the same rust-preventive compound as used in the fuel tank and reinstall
Operate the engine for 5 minutes to circulate the rust-preventive compound throughout the engine.
Service the air cleaner.
Apply a non-friction, rust-preventive compound to all exposed parts. If it is convenient, apply the rust-preventive
compound to the engine flywheel.
Drain the engine cooling system (tag cap).
The oil may be drained from the engine crankcase if so desired. If the oil is drained, reinstall and tighten the
drain plug (tag cap).
Clean the batteries and battery cables with a baking soda solution and rinse them with fresh water.
Insert heavy paper strips between the pulleys and belts to prevent sticking.
Seal all of the openings in the engine, including the exhaust outlet, with moisture-resistant tape. Use cardboard,
plywood, or metal covers where practical.
Clean and dry the exterior painted surfaces of the engine. Spray the surfaces with a suitable liquid automobile
body wax, a synthetic resin varnish, or a rust-preventive compound.
Cover the engine with a good weather-resistant tarpaulin or other cover if it must be stored outdoors. A clear
plastic cover is recommended for indoor storage.
