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).

Do not reuse the old heater pipe.
