Farm Machinery Parts. Product Description Usually cold starting one time is equal to a 200-300 km drive in engine wear, and increases 20% fuel consumption. The Simate engine preheater is a simple plug-in heating device. It can effectively prevent the engine cold starting in the winter. Different from the common non-pump heaters (tank-type heaters), the Simate engine preheater is a pump-type preheater, it has an internal circulation pump. Therefore the preheater can be connected into the car heater hose simply. And it can force the coolant to circulate through the preheater and the engine, the preaheater heats the coolant continuously, and the circulating coolant warms up the engine. Thus the Simate preheater has more powerful heat output, and it can warm up the whole engine more quickly, the engine can reach a higher temperature also. Starting an well-warmed engine subjects to less wear and consumes less fuel, thus producing fewer harmful exhausts.
