As we all know that diesel engine temperature overhigh in may causes many tractor engine problems, such as coolant boiling and power decline. Also with temperature of the tank going high, the viscosity of the lubricant oil decreases , which increases the friction among the components in the diesel engine. More seriously, excess temperature increases the possibilities of some serious accidents, such as drawing cylinder and cylinder pad burning out. This article is about to talking about the reasons that cause high temperature of the tractor and harvester’s tank. Here is the analysis of the factors that cause high temperature of the tank:
