Reducing the High Temperature of Water Radiator Dump Truck (HD 785-7 Type) by Making Special Tool

Abstract

The high temperature of the engine in the dump truck vehicle will cause a decrease in the performance. Therefore, it is necessary to monitor and analysis the causes high temperature by creating a program called Intelligence Availability. This program is monitor and control the critical engine conditions and to make sure the engine coolant temperature can't exceed 85 ?C. In March 2018, 50 units HD 785-7 type have temperature above 85 ?C. The main cause is the dirty core of the radiator and the absence of tools to clean the cores, so it is necessary to make a special tool to clean the radiator cores by flushing method. This flushing method can reduce the high temperature to be normal.
