This preheat kit contains threaded electrical resistance heat elements located in each cylinder assembly, and four pad heat elements on the engine crankcase, oil sump, oil cooler, and tank. This multi-point configuration fully preheats the engine and attached accessories for reduced wear on startup and reduced run-up times at any temperature. Power is routed to the elements through a dedicated wiring assembly with system power indication and circuit overload protection. System is self-regulating through design. Heated components reach an average state of thermal equilibrium in approximately six hours.

This preheat kit when installed will supply 570 watts with a 5.0 amp draw at 115 volts.
This preheat kit when installed will supply 570 watts with a 2.5 amp draw at 230 volts.
