Electric Drive Cooling Fan Motor Mounting
2010-07-08
HISTORICAL
J2873_201007
This SAE Recommended Practice is applicable to Electric Drive Cooling Fan Assemblies used in Light Duty vehicle cooling systems (typically, passenger cars and light duty trucks). This document outlines the Electric Drive Cooling Fan Motor Mounting interface characteristics such that a common standard is possible.

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 (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
2021-12-13
CURRENT
J1468_202112
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.

Fan Hub Bolt Circles and Pilot Holes
2014-03-12
HISTORICAL
J635_201403
This Recommended Practice applies to engine cooling fans up to 2000 mm in diameter with a mounting interface consisting of a pilot hole and a circular bolt pattern. Most of these fans are belt, gear, clutch, hydraulically, or electrically driven.

FAN HUB BOLT CIRCLES AND PILOT HOLES
1984-07-01
HISTORICAL
J635_198407
The scope of the specification is limited to heavy-duty diesel engine manufacturers, fan suppliers, and end users. Standard mounting patterns are given for fans up to 2000 mm rotating diameter. Passenger car and light-duty fans were not addressed because committee members issuing the specification felt that standards for these fans could be better addressed by personnel working in the market segments which use those fans. Rationale for issuance of the specification is cost savings through reduction of part numbers and inventory. Failure to comply with this specification will result in the need to release and carry in inventory parts of identical blade geometry and construction, but with different mounting patterns.

FAN HUB BOLT CIRCLES AND PILOT HOLES

HISTORICAL
J635_199506
The purpose of this SAE Recommended Practice is to encourage the standardization of mounting patterns for engine cooling fans as new engines are designed and developed in SI metric units. It is specifically not the objective of the specification to address the soft metric conversion of existing mounting patterns on engines designed in English units. The scope of the specification is limited to heavy-duty diesel engine manufacturers, fan suppliers, and end users. Standard mounting patterns are given for fans up to 2000 mm rotating diameter. Passenger car and light-duty fans were not addressed because committee members issuing the specification felt that standards for these fans could be better addressed by personnel working in the market segments which use those fans. See Figure 1 and Table 1. Rationale for issuance of the specification is cost savings through reduction of part numbers and inventory.
