I figure if it doesn't squeal, it's tight enough. This is not a critical adjustment here. My thumb-o-meter has served me well for many years and belt changes with never a peep, shredded belt, or bearing wearing before its time.

I used Bando belt part #'s 6PK1175B and 4PK945B
I think they were like $30 or so.

Part numbers for the belts from NiSSan:

11920-AG900 Belt Compressor list price $18.82
11720-4P102 Belt Fan & Alternator list price $21.86

I purposely overtightened the belts knowing they would stretch just a wee bit as the Z runs.

I did my hoses at the same time, when you have the undercover off you have plenty of access, my original antifreeze was 3.5 years old when replaced

I did this, great write up. But unfortauntely my tension adjuster on the alternator pulley is ****ed because I snapped the head off the bolt. I was told that I can just dremel the old bolt out, and install a new one. Is this true, or do I have to replace the whole tension pulley w/ adjuster which costs $75 or so. Any help is appreciated on this..

Done! I did have to pull off the under tray and adjust a second time. I wasn't checking deflection from the top where I should have, and the AC belt was left a little loose. Got it tightened up perfectly now on both belts

Great write up...very easy DIY

Great write up. very easy to install new belts. Quick question, how essential is that plastic under tray. Mine is long gone after hitting two dead animals in a row in a lowered Z. Just messed up or ripped to many plastic pieces for it to properly stay there so I had to remove it. Should I replace it or is it not that important?

It is there so that the components are protected from road debris and the elements. It also serves to reduce the coefficient of drag. It isn't essential, but manufacturers put that there for a reason.

Just wanted to say thanks for posting this, step by step with great pictures. I'm a huge fan of doing what I can myself to my Z, and since I recently heard some squeeling noises coming from my engine when it wasn't completely warmed up and freezing outside, I knew my belts needed to be replaced. I look forward to replacing them with the help of this thread!

Thanks!!
