How to Replace an Alternator on a Gasoline-Powered Engine on Jeep Liberty?

To replace the alternator on a gasoline engine, start by connecting the negative battery cable so that you avoid getting hurt. Take out the generator drive belt, lift the plastic cover from the B+ stud and take off the top of the B+ terminal mounting nut. To break the connection, push on the tab at the back of the field wire connector for the generator. To remove the generator's mounting for the 2.4L engine, unbolt the two holding it in place; for the 3.7L engine, remove the vertical bolt as well as the two holding it horizontally. Once the generator has been taken out from the vehicle, lower the new generator onto the engine bracket and attach the two bolts for the 2.4L engine or the three bolts for the 3.7L engine, tightening the horizontal bolts next to each other and then the uppermost vertical bolt to the suggested torque. Fit the field wire connector into the rear of the generator, attach the B+ terminal and bolt to its mounting stud and snap the plastic cover back on the B+ terminal. Add the drive belt, making sure its path is accurate so your engine doesn't get too hot. After that, reattach the negative battery cable.

How to Install the Alternator on a 3.7L Engine on Jeep Liberty?

When installing the generator on a 3.7L engine, put it in position and tighten three bolts: two horizontally to 57 Nm and one vertically to 40 Nm. After connecting the field wire connector to the back of the generator, add the B+ terminal and nut to the generator stud, tighten the nut to 13 Nm. Attach the plastic cover onto the B+ terminal. Don't use a screwdriver to lift the belt over the pulley, because this might damage the synthetic material in the belt. Be sure to direct the serpentine accessory drive belt clearly to keep the water pump from rotating backward; use the belt routing label located in the engine compartment. After that, attach the drive belt and reconnect the negative battery terminal to the battery.

Another significant part of the Jeep Liberty's electrical system is an alternator which is its combined charger for the car battery and the generator that provides power to the automotive systems when the car is running. It functions by using the mechanical energy derived from the engine to generate electrical energy in the form of alternating current which is then converted to direct current used for recharging the battery as well as for powering several parts. The alternator generally has a two part cast aluminum case in which a stator and rotor are enclosed where the pulley and fan are on the shaft. For the years, there have been variations used in the Jeep Liberty vehicles and which include the high output ones that meet the extra load of electrical parts. In some vehicles such as customize ones or the ones with complex eletronical systems, these kind of high output alternators are most appropriate for handling high electrical loads.
