HT40MA Water Heater enables wide application on various engine coolant pre-heating. It has fine cast aluminum enclosure and self-extinguishing engineering plastics end closure, easy and convenient to use. 
If the ambient temperature is lower than 4ºC during cranking, engine coolant and lubricant may condense into solid state and lose their lubricating and cooling properties, which can damage the engine. Therefore, engine heater should be installed to ensure normal starting and running of the engine when the ambient temperature is lower than 4ºC. 
The inner heating pipe and end cover both adopt stainless steel with high corrosion resistance. The heater has light indication function, which can indicate power and heating status. 3 kinds of heaters with different heating temperature are optional (Standard heater: 40ºC; 50ºC and 60ºC heaters are needed to be customized).
This product is suitable for various engines with (13~25) L displacement.
