NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 3.2L OR 3.5L ENGINE.
SYMPTOM/CONDITION:
"Hiss" noise similar to a vacuum leak during engine idle and/or low RPM driving conditions. The noise is most noticeable during cold engine operation
from outside the vehicle, but may also be heard at normal operating temperatures and/or from inside the vehicle.
DIAGNOSIS:
Using the Mopar Diagnostic System (MDS/MDS2) and or the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual,
verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and
repair as necessary before proceeding further with this bulletin. If no DTC's are present, check all engine vacuum lines, connections, and air induction
tubes including the air cleaner and air cleaner filter box to assure that no restrictions, vacuum or air leaks exist. Verify that the EGR tube and seals are
properly seated. Check throttle body gasket seating and for cracks/splits or missing material. If no problems are found and the noise is still present,
perform the Repair Procedure.
