Fluid change is how often?

How often should I be changing the radiator fluid? Power steering fluid? Brake fluid? Transmission fluid? The truck is a 2012 Tacoma Access Cab 2.7 liter/4 cylinder motor 200,000 miles this year. Any oil additives ? , Just did oil change w/ purple synthetic oil. Now worried about all the other fluids.

Since you must not have an owners manual, the link above will get you a PDF version.

I'd not print it of course, but at least you can read it as needed.

 

Car Care Nut on YouTube has great recs for all these intervals. Excellent channel. The link above is great too.

 

Coolant every 50k. Trans fluid every 40k.
