Remy Alternator P/N:14939
Remy 12393 alternator for the 2001-2002 Jeep Wrangler 6-cylinder 4.0L and other vehicles charges the battery and powers the electrical system while the engine runs. This Remy unit is remanufactured and designed for dependability through the vehicle's service life.
Dim or flickering lights, a battery warning light or a battery that keeps going flat can point to a weak charging system. The belt or the battery connections can also produce those signs. Before you replace the alternator, look over the drive belt, battery terminals and wiring with the engine off for looseness or corrosion; a shop can test the charging output.
It fits the 2001-2002 Jeep Wrangler 6-cylinder 4.0L and works as an alternator for the 2001-2002 Jeep TJ 6-cylinder 4.0L. Each takes one.
