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 the 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.
