Steve, an alternative to the Wolverine-type pan heaters are the immersion type with a heating element in the engine's internal coolant, installed in a block port with pipe threads. I have these, made by Kim, called Hot Starts. I only use them before winter starts or during sub-freezing weather. They are 500 watt and I run them on timers, 2 hours on, 2 hours off, alternating between engines. The engine room stays about 25 degrees above ambient. I've done this through 15 winters with both Detroits and Cummins with no ill effects.
