The alternator on your 2002 Dodge Intrepid is nestled inside the engine compartment among several components. Still, you can gain access to it through the underside of your vehicle after removing a couple of components. Then you can easily remove the old unit and install the new one. The strategy allows you to accomplish the job in your driveway using a few common tools. This procedure applies to the 2.7-liter engine model.

Open the hood and detach the ground (black) battery cable, using a wrench.
Jack up the front of your vehicle, using a floor jack, and support the car on two jack stands.
Chock the rear wheels and apply the parking brake.
Detach the splash shield from under the engine compartment, using a ratchet and socket.
Unfasten the transmission cooler mounting bolts, using a ratchet and socket, and move the cooler to the side.
