Product Storage
Sealed Coolant System
Ensure that the cooling system is filled with Perkins
ELC, or an antifreeze that meets "ASTM D6210"
specification.
Open Cooling System
Ensure that all cooling drain plugs have been
opened. Allow the coolant to drain. Install the drain
plugs. Place a vapor phase inhibitor into the system.
The coolant system must be sealed once the vapor
phase inhibitor has been introduced. The effect of the
vapor phase inhibitor will be lost if the cooling system
is open to the atmosphere.
For maintenance procedures refer to this Operation
and Maintenance Manual.
Monthly Checks
The crankshaft must be rotated in order to change
the spring loading on the valve train. Rotate the
crankshaft more than 180 degrees. Visibly check for
damage or corrosion to the engine.
Ensure that the engine is covered completely before
storage. Log the procedure in the record for the
engine.
