However, if circumstancesrequire addition and prediluted aqueous engine coolant is not available,use the appropriate engine coola
36、nt concentrate (Type I or II) diluted to 50volume % with water of at least the quality outlined in Table X1.1.3.6 When diluting engine coolant concentrates for actualservice, use a municipal (treated) water, or a low-mineralcontent well water (see Appendix X1, Table X1.1). If suchwater is not availa
37、ble, use deionized (demineralized) or dis-tilled water. This procedure will minimize the formation ofhard water scale and avoid the introduction of mineral com-ponents, such as chlorides and sulfates, that can increase thecorrosion rate of aluminum and iron.3.7 When installed in accordance with the
38、vehicle manufac-turers recommendations and those on the product label, enginecoolant concentrates or prediluted glycol base engine coolantsshall be suitable for use in a properly maintained coolingsystem (Appendix X1) in normal light-duty service for aminimum of one year without adversely affecting

Detailed Requirements4.1 Glycol base coolant concentrates and prediluted cool-ants shall conform to the physical and chemical requirementsprescribed in Table 2 depending on coolant type (see 1.2).4.2 The requirements listed in Table 2 for prediluted cool-ants (Types II
40、I and IV) are prescribed for the coolant aspackaged, without further dilution or adjustment.4.3 All coolant concentrates and prediluted coolants shallconform to the performance requirements listed in Table 3.4.4 Coolant concentrates shall be diluted for performancetesting as described in the individ
41、ual ASTM test methods.4.5 If necessary, the freezing point of prediluted coolantsshall be adjusted with deionized water before proceeding withperformance testing.

44、 Before installing engine coolant, the cooling systemshould be inspected and necessary service work completed.X1.1.2 Cooling system fill should consist of coolant con-centrate and water or prediluted glycol base engine coolant (50volume % minimum).X1.1.3 When preparing solutions, the water should be
45、 ofsuch quality that it does not contain excessive solids, hardnesssalts, sulfates, or chlorides.

Themost accurate and preferred means of determining coolantconcentration is by the refractometer. (See X

ASTM MNL 6 provides suggestions for properwater quality limits.X1.5 CautionDo not remove the radiator pressure capwhen the engine is hot. The cooling system will likely be underpressure. When the engine has cooled, carefully turn to the firstnotch to vent the system pressure, then remove.
