Condition
Cause
North America
Some customers may comment that the SES lamp is on or the engine may have a slight noise coming
from the front of engine belt area.
This noise may or may not be present at the time vehicle comes in.
Upon investigation you may find DTC P0324 set in the ECM.
Vehicle may also have a slight squeak noise coming from the front of engine. We have determined
that at times this code can be set by noise from the water pump.
Correction:
If this condition is found perform the following inspections prior to diagnosing per SI.
a) Listen to the water pump with a stethoscope or chassis ears to see if any unusual noise is
heard. Compare to similar vehicle to confirm.
b) Watch the knock retard bank to bank on GDS2, then remove the belt and observe knock retard
again. If there is a difference this PI applies.
If no noises are heard or there is no difference in knock retard then this PI does not apply.
Normal SI diagnostics should be followed.
If a noise is heard or a difference is made removing the belt, then replace the water pump and
reevaluate the
concern.
NOTE: This is a preliminary temporary diagnostic and repair. As more investigation information
becomes available this PI will be updated or advanced to a bulletin.
