Just bought a used 04 with 115 k. the belts are..."worn"

using this to help me do them tomorrow. thanks for it!

 

Great write up. Just did this today, should have been a short job but it turns out the previous owner had under drive pulleys. Took four trips to the auto parts store to get the right belt.

 

had to change mine around 85k miles (belt started cracking but probably could have gone on for quite a few more miles before it would have actually snapped).

went back twice to re adjust the tension before i got it right

 

snapped my ac belt tonight will be using this !

 

my ac belt is WRECKED! Replacing with OEM on monday.

 

WOW!!! I didn't know it was gonna be that easy. Thanks to this DIY.

 

I was having issues with good year gatorback belt and even after adding tension it would squeal. I ordered OEM belts for $37 shipped and found out that oem belts use FELT on the ribs to help keep it quiet compared to other belts available after market. I also picked up a BT3373 belt tension gauge.

I installed the OEM belts and did not have the gauge and chose what I thought was tight and to the point where no squealing occurred. I just got the tension gauge and checked my tension and I was off. The actual tension that is needed is really high compared to what I thought was around 20lbs and measuring deflection using a ruler and a hammer.

I would recommend investing in a belt gauge of some sort to check your tension for sure and not just add tension till there is no squealing. I have both tension and deflection in spec now. I am trying to figure out a way to rent my gauge out for the community.

GREAT write up, thanks very much!

 

How/where did you get the tensioner from?

Also, am i reading correctly, that the tension you now show is far higher than the specs for it?

 

i couldnt have said it better myself. i did mine tonight in less than an hour (with the undertray already off). this thread helped a lot! thanks!

 

I got the belt tension guage from ebay on an auction. I set the tension in between used belt adjustment and new belt. Since my belt was only 1 week old when I installed it and slightly stretched during the week. I will recheck the tension again and see how it settled and then adjust if it need to. Remember don't add to much tension and thrash all your bearing or be too loose and slipping / squealing. STICK WITH OEM BELTS

 

HAD A PROBLEM...had to leave one bad belt on.

Went to Nissan to order my belts A1920-AL510 (Compression) and 11720-4P102 (Fan & Alt). The compression belt was special order since it was not in stock.

The smaller of the 2 belts, the compression belt, was a little bit too small. I even fully removed the idler pulley to make room. Still a no-go.

*Side note...removed idler pulley for the bigger belt and it fit and worked fine.

Should I try to swap out the compression belt for another one? I was thinking not everything manufactured is good. Or is there another way to make it work?

 

If I am not mistaken the correct Nissan part number for the OEM belt is 11920-AG900 - so I think that may be your problem.
I just did mine last week and that is the belt I used with no issues.
Did you loosen the idler pulley to its lowest setting and then try to slide the belt over it?
That's how I did it, I worked the belt over the crank and A/C pullies first and then slid the belt over the idler - it is tight but it will work.

 

I just requested it by the belt names and that's what they gave me. I'll tell them to get me that part number. Thanks

 

Just finished this....I had to double and triple check everything because it seemed too easy. The bolts on the idler pulley also wasnt as tight as i had thought for some reason...

Got the belts from my local Oreilly store...Alternator Gates Belt#K060465 for 20 bucks the other is Master Pro #K040372 for 15 bucks. Easiest install I've ever done to my Z..

 

My first post here... Thanks for the excellent write up!
I now know how to change the belts on my Renault Vel Satis
I tried before, but did not know I had to undo the pulley bolt itself, I thought it was just a bajonet fitting and only the tensioner bolt needed to be removed.... You guessed it, no movement what so ever!

As my car shares the engine with the fabulous 350Z... I will be here more often concerning all engine matters For the rest... I don't think there is anything similar!

F.y.i: I do drive something more sportive as well, My Lotus Elan!

Anyone know the torque for the tensioner bolt, 2007? Mine broke....in traffic....great friday afternoon! Thanks for your help, anyone.

 

According to my FSM for an '06, torque specs are 24-28 ft/lbs.

 

Different setup, but thank you for looking. I'll give in and buy the FSM for my year. Thanks again.
