No shortcuts here, please! Like never try
to dean the engine by spraying the engine
with the separator on. If you do, you'll wash
the dirt in the separator right into the engine
(ughl).
 Next, take the inlet air temperature sensing
element off the inlet housing by removing the
four retaining bolts. You do this to keep the
element from getting plugged with dirt
loosened dunng the deoning chore.

 Disconnect the pressure line from the air-
bleed actuator so the line won't get plugged
with loosened dirt. Put on AN929-6 cap on
the fitting.

 Have your buddy motor over the en- 1
 gine with the starter.
 Spray the quart of the dry cleaning
solvent evenly thru all sections of the
inlet. Be sure both sides of the inlet SPRAY IN A OUART
 OF DRY (LEANING
guide vanes are covered with the SOLVENTY
solvent.
 When the solvent is used up stop motoring the engine and let it set for an
hour or so to allow the solvent to soften and loosen the caked-on dirt.
 The dirt really builds up on inlet guide vanes, so go over them with a small,
round, fiber brush with a long handle when you return from your break.

 SPRAY WITH WATER
 Have your favorite throttle jockey start the engine and run it at flight idle.
 To get rid of the dirt loosened by the dry cleaning solvent, spray clean, fresh
water evenly into all sections of the inlet housing at a rate of 2 gallons per
minute for about 2 minutes.
 After the water treatment run the engine from 2 to 5 minutes to dry it out.
Shut down the engine.
