Question about 2006 Nissan Altima

Open Question

2006 Nissan Altima 2.5 belt tensioner question.

I'm changing the alternator on my 2006 Nissan Altima 2.5 liter engine. How do I loosen the belt? I can see the automatic tensioner, but its difficult to get a wrench near it. How do I loosen the belt enough to remove and replace the alternator with ordinary hand tools?

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.

Belt vibration


This may be a stupid question, but has the tensioner for the belt been properly tightened?  Does it squeal when it vibrates?  The tensioner for the alternator belt is on top of the alternator and is a bolt you tighten or loosen.  The tensioner for the AC belt is underneath and can accessed with the right front splash guard removed and the car placed on ramps.
