ENGINE BLOCK HEATER
DESCRIPTION
The engine block heater (1) is mounted in the cylinder
block (2), near the right rear corner. The block heater
is a dry cylinder type design and is powered by 110
volt AC. The power cord must be secured in its
retainer clips, and not positioned so it could con-
tact linkages or exhaust manifolds and become
damaged.
The engine block heater (1) is mounted in the cylinder
block, near the left rear corner. The block heater is a
dry cylinder type design and is powered by 110 volt
AC. The power cord must be secured in its
retainer clips, and not positioned so it could con-
tact linkages or exhaust manifolds and become
damaged.
OPERATION
When power is applied (110 volt AC) to the block heater, the heating element transfers heat through the aluminum
engine block and into the coolant without directly penetrating the cooling system.
DIAGNOSIS AND TESTING
ENGINE BLOCK HEATER
If unit does not operate, trouble can be in either the power cord or the heater element. Test power cord for conti-
nuity with a 110-volt voltmeter or 110-volt test light; test heater element continuity with an ohmmeter or 12-volt test
light.
