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.

The purpose of this SAE Recommended Practice is to establish a testing procedure to determine the performance capability of heavy-duty vehicle cooling systems to meet Original Equipment Manufacturer or end user thermal specifications to ensure long term reliable vehicle operations. The recommendations from the present document are intended for heavy-duty vehicles including, but not limited to, on- and off-highway trucks, buses, cranes, drill rigs, construction, forestry, and agricultural machines.

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.

The purpose of this SAE Recommended Practice is to establish a testing procedure to determine the performance capability of the engine cooling system and, if so equipped, the charge air cooling system on onhighway trucks with liquid-cooled internal combustion engines.

The purpose of this SAE Information Report is to define common industry terminology and nomenclature relative to thermal flow control valves and to describe common thermal flow control valve applications in automotive, highway truck, mobile construction equipment, and industrial applications. This document is primarily directed at internal combustion engine or electric powered applications and the downstream systems to which power is provided, such as transmissions, hydraulics, air compression, etc. The information contained herein does not constitute an SAE Standard.

This SAE Recommended Practice was developed primarily for passenger car and truck application, but may be used in marine, industrial, and similar applications. It addresses non-metallic caps and both metallic and non-metallic filler necks.

It is necessary to identify and attempt to evaluate the characteristics of an application which can have an effect on fan durability. Failures almost always occur in fatigue, so careful attention should be paid to avoid resonance or forced vibration of the fan. This section considers vibrational inputs, fan natural frequencies, and operating speed as part of the initial structural integrity analysis. A fan application fact sheet (Table 1) is recommended as a form to communicate between user and fan supplier.

Three levels of fan structural analysis are included in this practice: 1 Initial Structural Integrity 2 In-vehicle Testing 3 Durability Test Methods The Initial Structural Integrity section describes analytical and test methods used to predict potential resonance and, therefore, possible fatigue accumulation. The In-vehicle (or machine) section enumerates the general procedure used to conduct a fan strain gage test. Various considerations that may affect the outcome of strain gage data have been described for the user of this procedure to adapt/discard depending on the particular application. The Durability Test Methods section describes the detailed test procedures that may be used depending on type of fan, equipment availability, and end objective. Each of the previous levels builds upon information derived from the previous level. Engineering judgment is required as to the applicability of each level to a different vehicle environment or a new fan design.
