Freeze plug, or frost plug, block heaters install in an existing freeze plug opening in the engine block. The heater is secured using a V-Lok expansion mechanism with an o-ring that creates a reliable seal against the block. Once installed, the heating element is immersed and warms the coolant directly.
Designed to fit a dedicated threaded port within the engine block, threaded block heaters warm the engine by heating the coolant. The threaded design provides a secure installation and reliable seal while delivering efficient heat transfer to the engine.
Designed to fit a dedicated mounting location on the engine block, plate block heaters are secured using bolts and sealed with a gasket. Once installed, the heating element is immersed in the engine coolant, delivering consistent heat throughout the engine.
Cartridge block heaters install in a dedicated dry socket within the engine block, where the heating element warms the surrounding metal transferring heat throughout the engine. Unlike other block heater styles, cartridge heaters do not come in contact with the coolant.
Zerostart offers block heaters for a wide range of on- and off-road applications. Because each heater is designed for a specific engine, use the lookup tool below to identify the correct part number.
