TECHNICAL SERVICE BULLETIN
ALTERNATOR PULLEY AND
TENSIONER REPLACEMENT
SUBJECT:
This bulletin provides information related to the ECM software upgrade and alternator pulley
replacement for some 2013MY Sorento vehicles, produced from February 16, 2012 to
September 13, 2012, to improve idle RPM stability (750 to 680) while at a stop with A/CON. It
is important to note that the 2.4L GDI engine has a certain level of harmonic vibration while at
low idle RPM which is a normal characteristic of this engine design. For confirmation that the
latest reflash has been performed to a vehicle you are working on, verify ROM ID using the
tables in this TSB.
A CAUTION
DO NOT attempt to jack the engine up by the oil pan as this may result in damage
to the oil pan. In addition, the clearance between the oil pan and oil screen pickup is minimal and a collapsed pan can restrict oil flow into the pump assembly.
Any claims associated with this type of damage are not covered under warranty
and may result in a chargeback being issued to the dealer for improper repair.
