Low-Temperature Coolant Circuit Nomenclature and Applications
2018-11-08
CURRENT
J3136_201811
The document provides clarity related to multiple temperature coolant circuits used in on- and off-highway, gasoline, and light- to heavy-duty diesel engine cooling systems. Out of scope are the terms and definitions of thermal flow control valves used in either low- or high-temperature coolant circuits. This subject is covered in SAE J3142.

ENGINE COOLANT CONCENTRATE—ETHYLENE-GLYCOL TYPE
1973-06-01
HISTORICAL
J1034_197306
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.

ENGINE COOLANT CONCENTRATE - ETHYLENE-GLYCOL TYPE
1988-07-01
HISTORICAL
J1034_198807
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.

ENGINE CHARGE AIR COOLER NOMENCLATURE
1976-06-01
HISTORICAL
J1148_197606
This recommended practice is intended to outline basic nomenclature and terminology in common use for engine charge air coolers. An ENGINE CHARGE AIR COOLER is a heat exchanger used to cool the charge air of an internal combustion engine after it has been compressed by an exhaust gas driven turbocharger and/or mechanically driven blower. The use of an engine charge air cooler allows increased engine output because of the denser and cooler air available for combustion. Normal cooling sources are the engine’s coolant, a raw water source or air. Engine charge air coolers are often referred to as either INTERCOOLERS or AFTERCOOLERS depending upon their location, relative to the final compression stage, in the air induction system. Nomenclature sketches are presented below for the following general types of engine charge air coolers:

Engine Charge Air Cooler (CAC) Nomenclature
1990-06-01
HISTORICAL
J1148_199006
This SAE Recommended Practice is intended to outline basic nomenclature and terminology in common use for engine charge air coolers, related charge air cooling system components, and charge air operating and performance parameters. An engine charge air cooler is a heat exchanger used to cool the charge air of an internal combustion engine after it has been compressed by an exhaust gas driven turbocharger, an engine driven turbocharger, or a mechanically or electrically driven blower. The use of a charge air cooler allows increased engine horsepower output, and may reduce emission levels and improve fuel economy through a more complete combustion due to the increased air density available. Typical cooling media includes the engine's coolant, ambient air, or an external water or coolant source.

COOLANT CONCENTRATE (LOW SILICATE, ETHYLENE GLYCOL TYPE REQUIRING AN INITIAL CHARGE OF SUPPLEMENTAL COOLANT ADDITIVE) FOR HEAVY-DUTY ENGINES
1990-04-01
HISTORICAL
J1941_199004
This SAE Recommended Practice applies to engine coolant concentrate, low silicate ethylene glycol base, for use in cooling systems of heavy-duty engines. An initial charge of supplemental coolant additive (SCA) is required when using this type of coolant concentrate. This document applies to engine coolant concentrates for heavy-duty engine requirements. SAE J1034 applies to coolant concentrates for automobile and light truck applications. For further information on engine coolants, see SAE J814.

Oil Cooler Application Testing and Nomenclature
2017-03-21
HISTORICAL
J1468_201703
This SAE Recommended Practice is applicable to oil-to-air and oil-to-coolant oil coolers installed on mobile or stationary equipment and provides a glossary of oil cooler nomenclature. Such oil coolers may be used for the purpose of cooling automatic transmission fluid, hydraulic system oil, retarder system fluid, engine oil, etc. This document outlines the methods of procuring the test data to determine the operating characteristics of the oil cooling system and the interpretation of the results.
