In-Block and Replacement Thermocords

HOTSTART In-block Thermocords complete the in-block heater assembly, providing a power cord and plug for use with the installed engine block heater. Cords are available with or without thermostats and come in a range of lengths and plug options for your power connection. These thermocords also fit most non-HOTSTART in-block heaters. 

Thermocords can also be ordered to replace existing heater cords. Contact HOTSTART Customer Service at 509-536-8660 or sales@hotstart.com for help in selecting the proper replacement for your existing heater and application.  

HOTSTART's TwinStat^TM Thermocord is an energy efficient, idle reduction heater cord ideal for fleet operations. The cord's twin thermostats monitor engine temperature and ambient temperature, allowing for the heater to run only when needed in the coldest weather. When the ambient temperature is warm, the heater does not run, saving on energy. When the ambient temperature is cold, the heater operates until the engine is within the correct temperature range and then shuts off.
