PLATE-SEALING 4755915 - Caterpillar

Conventional Coolant System
Completely fill the cooling system before storage.Water or water which is mixed with supplemental coolant additive (SCA) is not an approved coolant for use with Cat C7-C32 Marine Engines which are cooled with heat exchangers. Cat C7-C32 Marine Engines which are cooled with heat exchangers require a minimum of 30 percent glycol to prevent cavitation of cooling system components. A minimum of 50 percent glycol is verystronglyrecommended.Refer to this Operation and Maintenance Manual, "Refill Capacities and Recommendations" or refer to this Operation and Maintenance Manual, "Fluids Recommendations" for more information about coolants.Raw Water System
Completely drain the raw water system by removing all the drain plugs from the raw water pump, the water shielded manifolds, the heat exchanger bonnets, and the aftercooler.After the system has been drained, inspect all zinc plugs (normally painted red) 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. Refer to this Operation and Maintenance Manual, "Belts - Inspect/Adjust/Replace" or refer to this Operation and Maintenance Manual, "Belts - Inspect/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.
Pressure lubricate the engine before starting the engine. Pressure lubrication of the engine ensures immediate lubrication. Pressure lubrication of the engine prevents damage to the engine which might otherwise occur at start-up. If the engine is not equipped with a prelube pump, contact your Cat dealer for information about lubrication of the engine before the engine is started.
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 to 6 percent concentration of coolant conditioner. Add liquid coolant conditioner or a coolant conditioner filter, 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.
If the engine is equipped with a fresh water system, ensure that the system is clean. Ensure that the system is full. Ensure that the system has the correct amount of supplemental cooling system conditioner.If the engine is equipped with a raw water system, install all the drain plugs and zinc plugs. Fill the system. It may be necessary to prime the raw water system pumps before operation.
On the first day of operation, check the entire engine several times for leaks and correct operation.
