Fluids and what else?

[Nismo0941se]

Ok in short many many questions
Bought a 2009 coupe 3.5se a few months back
It had 52,000 on it when i got it
It now has 66,400 miles


My questions
At this mileage what should i replace or change as far as fluids??
I jus did a full synthetic oil change 2 days ago
So thats done


Cvt?
Coolant?

Also bought a serp belt even tho no signs that mines bad
Jus figured the belt is a good 5 years or more old now

Why not replace

It also got a fresh set of tires about 3 months ago

So thats done too.

O and i chnaged the cabin filter and got and upgrade oil filter.

All sugestions welcome

And this is my first post so hello all!

Other people on the forum will tell you to check the fluids and then change them if needed. But personally I like to change ALL fluids when I get a used car so I know for sure how old the fluids are. But thats just me. Congrats on the purchase though.
