2、, Ford Global Technologies, Inc. COOLANT, HEAVY DUTY FOR DIESEL/TRACTOR - ESE-M97B18-C CONCENTRATE NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is an ethylene glycol type corrosion inhibited coolant concentrate, composed essentially of mono-ethylene glycol. This
3、coolant is not recommended nor intended for use in passenger cars or in light trucks. 2. APPLICATION This specification is released for material which when mixed with water, shall be a satisfactory fluid for diesel and tractor engine cooling systems. This material is for both initial fill and servic
4、e use. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 QUALIFICATION The material shall be inhibited sufficiently to be satisfactory for use in t
5、he cooling system. Qualification under this requirement shall be based on engine and water pump cavitation tests conducted by Ford Motor Company or a qualified independent laboratory. 3.2.1 Engine Test, min 670 h (FLTM BL 102-01) 45/55 mixture of test coolant and Detroit city water. Test is to be ru
6、n continuously 670 h with no downtime permitted except for removal of coupons. Maximum weight loss in mg/specimen on metal specimens are as follows: Each Material 100 h 0-300 h 300-670 0-670 h Aluminum 14 19 19 24 Cast Iron 19 19 19 24 Steel 18 22 26 31 Brass 18 18 22 22 Solder 88 131 131 131 Copper

Some deviation may be permitted but a mixture which causes pitting of any metal specimen shall be rejected even though the weight loss is under the limit given above. Weight losses
8、*greater than those listed may be permitted for interim samples if the specimens exposed for the full test period (670 h) show approximately the same weight loss as the interim period (100 h). *This indicates the cleaning method has removed a protective film formed by reaction with metal surface at
9、start of test. Coolant samples taken at specified intervals shall meet the following limits: pH, min 7.3 Reserve Alkalinity, max 25.0% decrease If engine components at the conclusion of the test exhibit any evidence of significant corrosion or attack, the coolant shall be considered unsatisfactory r
10、egardless of its performance in the tests above. 3.2.2 Water Pump Cavitation Corrosion, min #8 rating (FLTM BL 3-1) 3.3 ACCEPTANCE 3.3.1 Glassware Corrosion Test (FLTM BL 1-1) The loss in weight of metal specimens at the end of the normal two-week test shall not exceed 9 mg on steel, copper and bras
11、s, 10 mg on cast iron, 16 mg on solder, and 31 mg on aluminum. Some deviations may be permitted but a concentrate which causes pitting of any metal specimen shall be rejected even though the weight loss is under the limit given above. Weight losses* greater than those listed for two-week tests may b
12、e permitted if samples from an extended period (six weeks or more) show approximately the same weight loss as the interim period. *This indicated the cleaning method has removed a protective film formed by reaction with metal surface at start of test. 3.3.2 Color Green, (equivalent to 22.5 mg/L Uran
13、ine C and 33 mg/L Alizarine Cyanone Green G Extra) color to remain for life of coolant. 3.3.3 Staining (FLTM AL 1-1) The dye used in this material shall not discolor or stain white painted panels any more than 50/50 Alizarine Cyamine Green “G“ Extra and Uranine “C“.

15、shall have a freezing point of -37 C maximum. The freezing point is defined as the maximum temperature obtained after beginning of crystallization. The undercooling must not exceed 1 C. 3.3.7 Foaming 5 s for “eye“ to appear Test Method: Pour 250 mL of 30% solution of the material with distilled wate
16、r into a 500 mL glass stoppered graduate. Place in an oven at 70 C until the solution reaches 70 C. Remove from oven and shake the graduate for 1 min with one up and down stroke every 2 or 3 s. Place on bench with stopper removed. Time with a stop watch until an “eye“ appears. The term “eye“ refers
17、to a condition which exists when the surface of the liquid can be seen through the foam. 3.3.8 Compatibility All coolants submitted to this specification shall be compatible with all coolant previously approved under this specification. 4. GENERAL INFORMATION The information given below is provided for clarfication and assistance in meeting the requirements of this specification. The intent of this specification is to provide the basis for a no silicate or a low silicate coolant similar in composition to GM 6038-M but not as restrictive.
