In-Block Immersion Heater

In-Block heaters mount directly into the water jacket of the engine and can reduce engine wear due to cold starts by up to 50%. Warming the engine to the proper temperature also reduces idling and cranking time, saving fuel and minimizing maintenance. Preheaters are available for most leading makes and models of heavy-duty truck engines and are CSA approved. To specify an in-block heater for your heavy-duty engine, please select your engine manufacturer and model in the drop-down below.
