Haven't had my radiator fluid change. It was just brought to my attention, bought the car with 30,000 miles now I'm at 80k ! I did a cvt fluid drain and fill at 60,000 but need to know what else to do maintenance wize. Probably need a new belt.. What else?

 

The maintenance manual says every 30k miles, so I'd say now's a good time. You're probably okay as most coolants/antifreeze formulas resist breakdown and likely won't turn acidic but go ahead and drain/fill.

Here's a link to the maintenance manual:

I would suggest a flush/fill.
