HOW DOES THE ENGINE BLOCKHEATER WORK
The engine block heater warms the enginecoolant. This allows the climate controlsystem to quickly respond. The equipmentincludes a heater element installed in theengine block and a wire harness. You canconnect the system to a grounded 110 voltAC electrical source.
Note:The engine block heater is mosteffective when outdoor temperatures arebelow 0°F (-18°C). We recommend the useof engine block heater to improve enginecold start performance.
USING THE ENGINE BLOCKHEATER
Make sure the receptacle terminals areclean and dry prior to use. Clean them witha dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hoursof energy per hour of use. The system doesnot have a thermostat. It achievesmaximum temperature afterapproximately three hours of operation.Using the engine block heater longer thanthree hours does not improve systemperformance and unnecessarily useselectricity.
