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.
