SAE J1393, “Heavy Duty Vehicle Cooling Test Code,” has just been revised and the new J1393-2012 is available from Document Center Inc. now in either paper or pdf format. 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.
SAE J1393-2012 replaces the previous edition, SAE J1393-2004, which is now obsolete. Additionally, the document replaced SAE J819, “Engine Cooling System Field Test,” when that recommended practice was cancelled in April 2009.
