Engine block heaters are essentially just a water-heater element that look and operate just like the units that warm water in your home’s basement. They’re mounted in a hole in the engine’s lower block and live submersed in the liquid coolant. Most could fit in the palm of your hand before installation and are powered by normal 120V household electrical current via a purpose-made cord — the sort you’ve likely noticed poking out from the corner of some vehicles’ hoods.
ounted in the bottom of the cooling system, these are completely submerged so they won’t burn themselves out. Likewise, block heaters don’t present any danger to the engine as they can’t overheat things, and as their circuits are safely grounded, they won’t present any risk to home outlets or properly rated extension cords.
