with preservatives and the crankshaft should not be barred over. The tag should indicate: if coolant has been removed,
the date of treatment, and that the engine is not ready to run.

Store the engine in an area where the air is dry and temperature uniform.
NOTE
Engines in storage for more than 24 months should be flushed out with a suitable
solvent or a light, hot oil, and then be reprocessed with rust preventive materials.
Periodically inspect the engines for rust or corrosion. Take corrective action as
