The only thing that I've been told that would be good to get done by Nissan is the trans service, since Nissan has specific fluid that is needed. Or, at least that is what I was told by a local repair shop.
I am the tech manager at Prestone Coolants. Prestone extended life coolant exceeds all ASTM standards for coolant set forth by Nissan. You can drain and flush your cooling system and use Prestone extended life coolant in your Versa. If you need instructions, I am happy to send them, just send your year and engine size to [email protected].:thumb2:
