Using the Engine Block Heater
Make sure the receptacle terminals are clean and dry before use. To
clean them, use a dry cloth.
The heater uses 0.4 to 1.0 kilowatt-hours of energy per hour of use. The
system does not have a thermostat. It achieves maximum temperature
after approximately three hours of operation. Using the heater longer
than three hours does not improve system performance and
unnecessarily uses electricity.
