A/C - Heater Pipe Comes Out of Cylinder Head
SOURCE: Kia Technician Times
TITLE: Heater Pipe
APPLIES TO: 98 Sephia
SERVICE TIP:
CONDITION
The heater pipe has come out of the cylinder head on some vehicles resulting in a loss of engine coolant.
CAUSE
This condition is caused by insufficient interference fit of the pipe into the cylinder head due to insufficient hardness of the heater pipe.
CORRECTIVE ACTION
Beginning with 3/23/98 production, improvements were made to the heater pipe and the installation process at the factory. To correct this condition on
all vehicles produced prior to the production change, install a new heater pipe (P/N 0K247 15 270A).
