There are many types of block heater cords. This block heater cord has a temperature sensing switch installed inside the end that plugs into the extension cord which turns on the power to the engine block heater element when the outside temperature reaches. It senses the outside temperature to ensure the block heater turns on at the right temperature which is 0 degrees. It will not supply power to the heater until the temperature reaches.

This specific block heater cord for your engine includes a built in thermostat and if this recommended cord is not used you will trigger a fault code. It is best to unplug the existing cord from the block heater element to determine what end style you need.
