2006 Altima 2.5 Belt Tensioner Pully
First of all let me say thank you to the people who post here trying to help everyone.
When I reviewed the service manual for changing the Drive Belt (2.5L), it referenced using a special tool to remove the tension from the tensioner. Alas I do not have the special tool. Is there an alternative method? |

A 14mm wrench will work, or you can just pull on the belt between the alternator and compressor until the holes on the tensioner line up and then stick a screwdriver in the holes. It will keep the pulley in place and allow you to remove the old belt and install the new belt without having to hold the wrench on the tensioner. After you get the belt on just pull in the same spot again and slide the screwdriver out.

Thanks for the quick reply.
Do you typically work this from above or below the engine? |

Yes- I removed the tire and the access panel so I could work the belt in.

I've just done this past weekend. Here is how to do it:
1 - remove wheel 2 - Remove side plastic cover, behind wheel, by taking off plastic clips 3 - locate the auto tensioner, it has a 14mm bold in the center. Put a wrench on it, and turn it as if you were tightening. You will see the whole tensioner move. There is a hole in the tensioner that needs to line up with another hole on the engine. 4- Once both holes are lined up insert a screw driver through both holes, then you can let go of the tensioner. 5- now you can just remove the belt and put the new one in. 6- Once the new one is in, remove the screwdriver from both holes and the tensioner will spring back and stretch the new belt. DONE |

Removal of the tensioner pulley a problem?
I recently changed the drive belt on my wife's 2006 2.5 Altima. I'd done this kind of job on other vehicles, and didn't anticipate much trouble.
After fumbling with the tensioner for a few minutes I took some bad advice from a friend and loosened the tensioner pulley to get the belt off. Only later did I go online and read in a manual posted here which informed that I had to torque the tensioner pulley bolt clockwise and line up the “Boss” holes… However, the manual also stated that “You should never turn the bolt holding the tensioner pulley on counter-clockwise. If this bolt IS turned counter-clock-wise, you must replace the pulley along with the entire belt tensioner.” Well, I put her all back together and she runs like a top. What does it matter if you remove the pulley? Should I be concerned that the new belt and/or tensioner will fail prematurely because I removed and reinstalled the pulley? Thanks for any advice that may be provided. |

Thanks for the information. Will you kindly keep a log say the date and mileage when you did this procedure. I am most curious if a failure occur, how long it took to happen. I hope nothing happens.
Let us know. Thanks. |

Will do, Benny.
Are you aware of why the manual would state that? It is just a smooth pulley with a center bearing. How could removing it and replacing it effect the tensioner? Confusing to me... |

Just did this job myself
2005 Nissan Altima 2.5 serpentine belt replacement. I didn't have the special tool so I improvised with a 14mm wrench. (Unfortunately, there wasn't enough room to get a socket onto the belt tensioner, which would have been easier to manage than the wrench.) I did not have to remove the passenger tire, only the plastic splash guard that keeps water and such from splashing up into the belt area. I drove the car upon a set of ramps for easier access to get underneath it. I worked from below while an assistant worked from the top. I had him insert the screwdriver into the belt tensioner holes while I worked the 14mm wrench from below to get the holes aligned. With the proper tool it's possible one person could do it by himself, but having an assistant makes it easier. The screwdriver you need is a medium sized phillips head, but not too long. Work it in between the oil level checker and the engine to get the right angle to be able to get it through both holes. Once we had the screwdriver in place it wasn't too hard to work the old belt off and the new belt back on. Here again teamwork was beneficial, but probably not essential. Once the new belt was in place I again worked the tensioner from below while my assistant removed the screwdriver from above. While he was watching the belt to see if it was properly aligned I gently bumped over the engine from inside the car. The hardest part was probably getting that little splash guard back on.
A few tips: Use a digital camera to take a few snapshots of the belt in place before you take it off. If you get confused you can refer back to them when placing the new belt back on. Remember the ribbed side of the belt has to go against the ribbed pulleys while the smooth side goes up against the smooth pulleys. It's not too difficult to remove the water reservoirs to give you a bit more room to work with and to see better, but I didn't need to remove them. Take note of which pulleys the belt completely encircles and which it only partially encircles. Make use of the screwdriver in the belt tensioner holes trick to keep the tensioner in the slack position until you get the new belt on -- this is a godsend. Get an assistant to help you if you can, it will make the job a lot easier. |

I used a 14MM OFFSET box wrench with a pipe slipped over the other end for more leverage. That way you can do it alone, wrench left hand, screwdriver right hand. Don't even have to jack it up.
