This SAE Information Report is a source of information concerning the basic properties of engine coolants which are satisfactory for use in internal combustion engines. Engine coolant concentrate (antifreeze) must provide adequate corrosion protection, lower the freezing point, and raise the boiling point of the engine coolant. For additional information on engine coolants see ASTM D3306 and ASTM D4985.

This standard covers glycol-type compounds which, when added to engine cooling systems at concentrations of 50 - 70% by volume of coolant concentrate in water, provide corrosion protection, lower the freezing point, and raise the boiling point of the coolant. Such compounds are intended for a minimum of 1 year (approximately 12 000 miles) service in a properly maintained cooling system. (Reference: SAE HS-40, Maintenance of Automotive Engine Cooling. Systems.) Coolants meeting this standard do not require the use of supplementary materials. For additional information on engine coolants, see SAE J814. Heavy-duty non-automotive and heavy-duty diesel engine coolant maintenance may require different measurement and test parameters due to differences in engine design and materials, and high mileage service requirements.

This standard covers glycol-type compounds which, when added to engine cooling systems at concentrations of 40-70% by volume of coolant concentrate in water, provide corrosion protection, lower the freezing point, and raise the boiling point of the coolant. Such compounds are intended for a minimum of 1 year (approximately 12,000 miles) service in a properly maintained cooling system. (Reference: SAE HS-40, Maintenance of Automotive Engine Cooling Systems.) Coolants meeting this standard do not require the use of supplementary materials. For additional information on engine coolants, see SAE J814.

Three levels of fan structural analysis are included in this practice: 1 Initial Structural Integrity 2 In-vehicle Testing 3 Durability Test Methods The Initial Structural Integrity section describes analytical and test methods used to predict potential resonance and, therefore, possible fatigue accumulation. The In-vehicle (or machine) section enumerates the general procedure used to conduct a fan strain gage test. Various considerations that may affect the outcome of strain gage data have been described for the user of this procedure to adapt/discard depending on the particular application. The Durability Test Methods section describes the detailed test procedures that may be used depending on type of fan, equipment availability, and end objective. Each of the previous levels builds upon information derived from the previous level. Engineering judgment is required as to the applicability of each level to a different vehicle environment or a new fan design.

All materials classified as nylons share certain basic characteristics. However, even within the seemingly limited realm of glass fiber reinforced nylons, many levels and combinations of physical, thermal, and environmental resistance properties are available. These properties result from such factors as the following: 1 Type of nylon (6, 6/6, 6/10, 6/12, etc.) 2 Percentage (by weight) of glass fibers 3 Diameter and length of glass fibers 4 Wetting agent used to promote adhesion between resin and fibers (if present) 5 Heat stabilizer (if present) 6 Impact modifier (if present) 7 Pigmentation (if present) In order to select a material with appropriate characteristics, the prospective manufacturer and end user should investigate the proposed application thoroughly, and maintain open communication with the various material suppliers.

This document supersedes SAE J819 - Engine Cooling System Field Test. The purpose of this SAE Recommended Practice is to establish a testing procedure to determine the performance capability of engine cooling systems, including charge air coolers, on heavy-duty vehicles with liquid-cooled internal combustion engines. The definition of heavy vehicles for this document includes, but is not limited to, on- and off-highway trucks, cranes, drill rigs, construction, forestry and agricultural machines. Vehicles equipped with side or rear-mounted radiators may require an alternate procedure of a towing dynamometer because of peculiar aerodynamics. Testing is generally conducted to determine compliance with cooling criteria established by the engine manufacturer or the end product user to meet a desired engine reliability goal.
