Engine Storage - Short Term (14-07) Section 14 - Engine Testing - Group 14 M11 Page 14-52 Remove the electrical wiring from the fuel pump solenoid. Drain the cooling system. NOTE: It is not necessary to drain the coolant if it is a permanent type antifreeze with a rust inhibitor. Do not drain the coolant if the engine is installed in a vehicle. Cover all openings with tape to prevent dirt and moisture from entering the engine. Install a warning tag on the engine. The tag must indicate that the engine does not contain oil and must not be operated. Store the engine in an area that is dry and has a constant temperature. Warning: Do not pull or pry on the fan to manually rotate the engine.
To do so can damage the fan blades. Dam- aged fan blades can cause premature fan failures which can result in serious personal injury or property damage. Use the accessory drive shaft to rotate the crankshaft two to three revolutions every three to four weeks.
