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.
