GENERAL DESCRIPTION
Engine block heaters are used to maintain coolant fluidity inside the engine's coolant passages. Coolant fluidity is a factor when vehicles are parked in
extremely cold areas (0°F or less) for extended periods of time. A block heater consists of a heating element, 0-ring, electrical connector, and a power
cord.
The block heater is the same shape and diameter as the engine's core plugs and permanently replaces a designated core plug. Refer to the chart on page 3
for block heater part numbers, application information, and core plug location and position.
To operate the block heater, attach the power cord to the block heater electrical connector and route it safely inside the engine compartment. Plug the
male end of the power cord into a standard 120V household electrical outlet. When operated overnight, the block heater will help prevent engine coolant
from thickening and/or freezing. This allows the engine to start and run normally in very cold ambient temperatures.
