How to Replace the Alternator in a Dodge Caravan

by Contributor

The alternator in a Dodge Caravan sends electrical current to various accessories in the vehicle while the engine is running. Most modern alternators have a built-in voltage regulator to ensure the voltage level remains constant. If your battery keeps running down or your headlights become dimmer while driving, you may need to replace the alternator.

Step 1

Determine which alternator your Dodge Caravan will need. You'll want to be sure the new alternator is compatible with your Caravan's engine. The models for 2001 to 2007 may have a 2.4 L EDZ, 3.3 L EGA or 3.8 L EGH engine. Models made after 2007 have a 3.3 L EGA, 3.8 L EGH or 4.0 L engine.

Step 2

Disconnect the negative battery cable with a socket wrench. Remove the windshield wiper module for 3.0 L and smaller engines or the right front lower splash shield for engines larger than 3.0 L. Remove the accessory drive belt with a socket wrench. You will also need to remove the lower bolt and wiring harness from the oil dipstick tube with a socket wrench if you have an engine larger than 3.0 L.

Step 3

Take the mounting bolts off of the alternator with a socket wrench and disconnect the alternator's electrical harness. This will allow you to remove the alternator assembly.

Step 4

Install the new alternator assembly and connect the electrical harness. Tighten the mounting bolts to 40 foot pounds with a torque wrench and install the accessory drive belt. You will also need to install the lower bolt and wiring harness from the oil dipstick tube with a socket wrench if your engine is larger than 3.0 L.

Connect the windshield wiper module or right front lower splash shield as required. Connect the negative battery cable with a socket wrench.
