The alternator is right on top of the 2.5L motor and held on by 2 14mm bolts. To remove the lower bolt (hard to reach), you must remove the coolant bottle and the IPDM fuse board and its metal box/bracket. A breaker bar really helped give enough torque to loosen the bolts. Approach the drive belt from under the front passenger tire. There is a tension adjuster (hard to reach) bolt that loosens the belt and allows you to remove it from the alternator.

You can go to your local Library, they usually have automotive manuals (Chiltons, Haynes, etc.) that you can check out. Or, you can purchase these at your local auto parts store $10-$20. They are very useful to have on hand and provide decent photos.

SOURCE: 2003 Nissan Altima 2.5 transmission

The 2.5 and the 3.5 transmissions are the same except for the side cover where the output gears are. The 3.5 uses thicker gears. They were made in Decherd Tn. Also the bell housing is different. The starter for the 3.5 is mounted in the bell housing and the starter for the 2.5 is mounted to the block.

My 2003 Altima 2.5s makes a humming type (vibration?)sound.


I have a 2003 Nissan Altima making a humming sound towards the front of the motor at idle in Park.

Not sure if alternator or compressor.

Not rattle from timing cover has to be something Nissan already denies.

How do you change the alternator and replace it with new alternator, for a 2003 Nissan Altima, with a 2.5 L engine ?


The alternator is right on top of the 2.5L motor and held on by 2 14mm bolts. To remove the lower bolt (hard to reach), you must remove the coolant bottle and the IPDM fuse board and its metal box/bracket. A breaker bar really helped give enough torque to loosen the 2 bolts. Approach the drive belt from under the front passenger tire. There is a tension adjuster (hard to reach) bolt that loosens the belt and allows you to remove it from the alternator. If the belt is still good, (don't remove entirely) save time and try to keep the belt in a similar position. I am not an experienced mechanic and job took me about 3 hours & $200 for the alternator.
