• Drainexhaustmanifoldsofrawwaterbyremoving½”NPTpipeplugs.
• Drainengineblockofrawwater(ifrawwatercooled).
 • For5.7Lapplications:removeknocksensors/drainplugsfrombothsidesofthe
engineblock.
 • For6.0Lapplications:removeelectricheater17mmAllenplugfromengineblock
rawwaterpumpside.Remove10mmAllenplugonstartersideofengineblock.
 • For6.2Lapplications:removeelectricheater17mmAllenplugfromengineblock
rawwaterpumpside.Remove10mmAllenplugonstartersideofengineblock.
• Drainheatexchangersofrawwater.
 • Opencooledsystemswillhaveanoil/transmissionheatexchanger.
  •Remove1/8”NPTdrainplugandallowdraining.
 • Closedcooledsystemswillhaveanoil/transmissionandengineheatexchanger.
  •Remove1/8”NPTdrainplugandallowdraining.
• Reinstallexhaustheaderdrainplugs,engineblockdrainplugs,andheatexchangerend
caps/drainplugsafterallrawwaterhasbeendrained.Drainothercomponentsthat
containrawwater,suchasthewaterheater.
• Fillallcomponentsofrawwatersystemwithanon-toxic-50F.(-45C.),-60F.(-51C.)or
-100F.(-73C.)Marine/RVAntifreeze.Freezeprotectionlevelwilldependonclimate
location.Marine/RV Antifreeze will provide freeze protection to water pockets
that did not drain and necessary corrosion protection.
Approximatelysix(6)gal-
lonsofMarine/RVAntifreezewillbeneededforopencooledsystems.Approximately
three(3)gallonswillbeneededforclosedcooledsystems.Therearetwomethodsfor
fillingyourenginewithantifreeze;
 • Open Cooled System
 •Closethru-hullwaterpickupseacock.
•Fillengineblockandheadsfromthermostathousing.Removebothexhaust
headerfeedhoses.Lifteithertheportorstarboardhoseashighaspossibleand
filluntilfull.Theotherremovedhoseallowsairtopurge.
•Fillportandstarboardexhaustmanifoldsbyremovingthermostathoseends.
Lifthoseendashighaspossibleandfilluntilfull.
 •Fillseastrainerifnotfull.
 • Closed Cooled System
  •Closethru-hullwaterpickupseacock.
•Fillrawwatercomponentsbyremovingbothone-inch(1”)hosesfromexhaust
downturnadapters.Lifteithertheportorstarboardhoseashighaspossibleand
filluntilfull.Thisshouldfilltherawwatersideoftheengineheatexchanger,
oil/transmissionheatexchanger,rawwaterpump,andseastrainer.Thesea
strainermayneedtobeopenedtopurgeair.
  •Fillseastrainerifnotfullbyendofprocedure.
  •Filldownturnexhaustadapterswith1/4to1/2gallonsofantifreeze.
  •Reinstallhoses.
