How do you replace an alternater in a 1997 dodge ram 150 truck

Hi,

You will be needigng the below;

New alternator

Socket wrench set

Torque wrench

Determine which alternator your Dodge Ram will need. You'll want to be sure the new alternator is compatible with your Ram's engine. A Dodge Ram made after 2001 may be equipped with a 3.7 L, 4.7 L, 5.7 L Hemi V8, 5.9 L Magnum V8, 5.9 L Cummins diesel, 6.7 L Cummins diesel, 8.0 L Magnum or 8.3 L Viper engine.

Disconnect the negative battery cable with a socket wrench. Remove the accessory drive belt and disconnect the wiring harness from the alternator. You will also need to remove the support bracket with a socket wrench for 3.7 L, 4.7 L and 5.7 L engines.

Take the mounting bolts off of the alternator with a socket wrench and remove the alternator assembly.

Install the new alternator assembly. If you have a 3.7 L engine, tighten the horizontal bolts to 42 foot pounds and the vertical bolt to 29 foot pounds with a torque wrench. Torque the long horizontal bolt and vertical bolt to 41 foot pounds and the short horizontal bolt to 55 foot pounds for a 4.7 L engine. Torque the mounting bolts to 30 foot pounds for all other engines.

Connect the wiring harness to the alternator, install the accessory drive belt and connect the negative battery cable.

I hope this helps.

Good luck.
