Fresh Water Systems
This information applies to all systems that contain fresh water, such as engine blocks, separate circuit aftercoolers, etc.Note: Water is not the preferred substance to use in cooling systems of Caterpillar diesel engines. If the stored engine will never be exposed to below freezing temperatures, completely drain the fresh water system. The system can be drained by removing the drain plugs from the following locations: engine block, oil cooler, body of the heat exchanger and radiator.Clean the system. Refill the system with approved water and supplemental coolant additive. For a definition of approved water, refer to Cooling Systems in this document. If the stored engine will be exposed to below freezing temperatures, completely drain the fresh water system. The system can be drained by removing the drain plugs from the following locations: engine block, oil cooler, body of the heat exchanger and radiator. Clean the system. Refill the system with Caterpillar Premixed ELC or 50 percent Caterpillar Antifreeze concentrate and 50 percent approved water.Note: Caterpillar Antifreeze concentrate is available only in the one gallon size. The Caterpillar Antifreeze concentrate should only be used to adjust the level of the cooling system.Raw Water Systems
Completely drain the raw water system by removing all the drain plugs from the raw water pump, water manifolds, heat exchanger bonnets, and the aftercooler. After the system has been drained, inspect all zinc plugs for damage from corrosion.Note: To ensure complete drainage and evaporation during storage, do not install the drain plugs and zinc plugs. Place all removed plugs in a cloth bag and fasten the bag to the engine for storage.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. The belts should be tightened to the specification that is found in the Operation & Maintenance Manual.
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 in case there are hydraulic locks or any resistance.
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 in order to prevent damage to the mechanism.
Pressurized lubricating of the engine is necessary to ensure immediate lubrication. Also, pressurized lubricating will prevent damage to the engine. The damage occurs in the first seconds after start-up. Note: Refer to "Pressure Lubrication Procedure".
Check the condition of all rubber hoses. Replace the hoses if it is necessary.
Before start-up, test the cooling system for a three to six percent concentration of coolant conditioner. Add liquid coolant conditioner or a maintenance coolant conditioner element, if the coolant system is low. Test the coolant mixture for proper nitrite level. Adjust the coolant mixture if it is necessary. Prime the engine with clean diesel fuel before starting.
If the engine utilizes a fresh water system, ensure that the fresh water system is clean and full. Also, the
