Freeze Plug Heaters are used to heat the engine fluids of gas and diesel vehicles to ensure quicker winter starts and reduce engine wear in cold weather. The heater is operated using standard household AC power and the heat generated is distributed throughout the engine by the convective flow of the warmed coolant. Highest rated; most efficient type of heater on the market today. The V-Loc(TM) locking system provides quick; trouble-free installation. Plated stamped steel & forged brass adapters with copper heating elements for maximum life and efficiency.
