Coolant System
Completely fill the cooling system before storage.Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for more information about coolants.Removal from Storage
Remove all outside protective covers.
Change the oil and filters.
Check the condition of the fan and alternator belts. Replace the belts, if necessary. Refer to this Operation and Maintenance Manual, "Belts - Inspect/Adjust/Replace" for the correct procedure.
Replace the fuel filter elements.
Remove the plastic covers from the air cleaner elements.
Use a bar or a turning tool to turn the engine in the normal direction of rotation. The procedure ensures that no hydraulic locks or resistance exist.
Before starting the engine, remove the valve cover or covers. Put a large amount of engine oil on the camshaft, cam followers, and valve mechanism to prevent damage to the mechanism.

(1) Plugs for oil system
If an engine is stored for more than 1 year, Caterpillar recommends pre-lubrication of the engine to avoid dry starting. Use a suitable pump to put engine oil into the engine oil system.The pump will need to create a minimum pressure within the engine of 0.25 bar (3.60 psi). This pressure is needed for 15 seconds to lubricate the internal surfaces.Remove one of the plugs (1) shown in illustration 1 to connect to the engine oil system. The connection required is 9/16 in x 18 tpi. Ensure that the correct oil specifications used. Refer to this Operation and Maintenance Manual, Fluid Recommendations for more information. After the engine internal surfaces have been lubricated, remove connector, and install plug (1). Tighten plug to a torque of 60 N m (530 lb in). Caterpillar recommends performing the procedure in a minimum ambient temperature of 0° C (32° F).
Check the condition of all rubber hoses. Replace any worn hoses. Replace any damaged hoses.
Before start-up, test the cooling system for a 3 percent to a 6 percent concentration of coolant conditioner. Add liquid coolant conditioner or a coolant conditioner element, if equipped.Test the coolant mixture for proper nitrite level. If necessary, adjust the coolant mixture.Prime the engine with clean diesel fuel before starting.
Ensure that the cooling system is clean. Ensure that the system is full. Ensure that the system has the correct amount of supplemental cooling system conditioner.
On the first day of operation, check the entire engine several times for leaks and correct operation.
If the engine was removed from storage in which temperatures of less than -12°C (10°F) were encountered, refer to Service Manual, SEBU5898, "Cold Weather Recommendations Operation and Maintenance".Extended Storage (Engine with DEF Tank)
Ensure a normal shutdown. Allow Delayed Engine Shutdown, or properly cool the engine prior to shutting down.
Ensure a proper DEF purge. Do not disconnect the battery disconnect switch within 2 minutes after key off.
Fill the DEF tank with DEF that meets all requirements defined in "ISO 22241-1".
Ensure all DEF lines, and electrical connectors are connected prior to prevent crystal from forming.
Ensure that the DEF cap is properly installed.Removal from Extended Storage (Engine with DEF Tank)
If the DEF tank was stored for a duration equal to or exceeding that listed in table 1 at the corresponding temperature, replace the DEF.If the DEF quality is in doubt, test with a refractometer. DEF must be within the required range defined in "ISO 22241-1". For more detailed information about testing DEF quality, contact the local Caterpillar dealer.
