Scope*1.1 This specification covers the requirements for fully-formulated glycol base coolants for cooling systems
3、of heavy-dutyengines. When concentrates are used at 40 to 60 % glycol concentration by volume in water of suitable quality, (see Appendix X1),or when prediluted glycol base engine coolants (50 volume % minimum) are used without further dilution, they will functioneffectively during both winter and s

However, several serious cases of very poor performance have been reported and substantiated in heavy duty fleets whenrecycled glycols from sources such a

40、hen untreated, all water is corrosive. Water having a highmineral content or corrosive materials is unfit for cooling system use.X1.1.1.2 When preparing coolant mixtures, the water should be of such quality that it does not contain excessive solids, hardnesssalts, sulfates, or chlorides. In the abse
41、nce of specific recommendations from the engine or vehicle manufacture, see Table X1.1.Contact your local water department, the responsible government agency, or submit a water sample for analysis if there is aquestion on water quality.X1.1.2 Coolant Concentrates:X1.1.2.1 The coolant concentration s
42、hould be maintained between 40 and 60 % glycol by volume, depending on the engineoperating environment. Freeze protection will be provided in accordance with Table X1.2.X1.1.3 Prediluted Engine Coolants:X1.1.3.1 Prediluted glycol base engine coolants (50 volume % volume % minimum) should be used wit
43、hout further dilution. Ifadditional freeze protection is required, coolant concentrate may be added to the prediluted engine coolant to increase the totalglycol content in the cooling system (see Table X1.2).X1.1.4 Supplemental Coolant Additive:X1.1.4.1 SCAs extend the life of the coolant by repleni
44、shing the additives that deplete during normal operation. SCAs, however,do not extend the freeze protection provided by the coolant concentrate.X1.1.4.2 Heavy-duty engine users experience has shown that coolants not meeting the criteria specified in A1.1 may not providelong term protection against c
45、avitation corrosion (liner pitting). User experience and published information shows the presence ofnitrite in an SCA or fully-formulated heavy-duty coolant is particularly effective in providing maximum protection.X1.1.4.3 New technology consisting of other chemistries may provide satisfactory prot
46、ection. Such chemistries can be establishedby agreement between producers and users upon demonstration of performance utilizing Test Method D7583. Optionally, suchdemonstrations can consist of comparative damage rating from testing in operating engines. One or both of these options may beapplied as
