However, if circumstancesrequire addition and predil

41、uted aqueous engine coolant is not available,use the appropriate engine coolant concentrate (Type I or II) diluted to 50volume % with water of at least the quality outlined in Table X1.1.4.6 When diluting engine coolant concentrates for actualservice, use deionized (demineralized) or distilled water

42、, mu-nicipal (treated) water, or a low mineral content well water (seeAppendix X1, Table X1.1). This procedure will minimize theformation of hard water scale and avoid the introduction ofmineral components, such as chlorides and sulfates, which canincrease the corrosion rate of aluminum and iron.4.7
