How to Replace the Alternator in a Kia Spectra

The alternator in a Kia Spectra 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.

Instructions

1

Determine which alternator your Kia Spectra will need. Make sure the new alternator is compatible with your Spectra's engine. All versions of the Kia Spectra have a 2.0 L engine.

2

Disconnect the negative battery cable, power steering pump and its bracket with a socket wrench. Remove the cover cap for the alternator's B terminal so you can disconnect the electrical connection from the alternator. Loosen the pivot bolt for the alternator and the tensioner mounting bolt with a socket wrench but do not remove them. Relieve the tension on the drive belt by rotating the adjustment bolt counterclockwise.

3

Take off the tensioner mounting bolt so you can remove the belt tensioner. Disconnect the pivot bolt for the alternator and loosen the bolt for the adjusting bracket. This will allow you to rotate the bracket up and remove the alternator.

4

Install the new alternator assembly and tighten the pivot bolt by hand. Move the adjusting bracket into position and install the belt tensioner. Tighten its mounting bolt by hand and install the drive belt.

5

Adjust the tension so that the belt deflection is .22 to .31 inches for a new belt and .33 to .45 inches for a used belt. Use a torque wrench to tighten the tensioner bolt to 14 to 19 foot pounds and the pivot bolt to 28 to 38 foot pounds. Connect the power steering pump and the negative battery cable with a socket wrench.
