thats because coolant is a bad conductor. the only reason we use coolant is to prevent seals from drying out, and to lube the water pump & thermostat & prevent the water from freezing. otherwise it doesnt actually cool as well as water does. water gets hot faster, thus being able to take away the heat from the metal better than coolant. the more water you have, the better cooling properties; but your freeze protection is less. in the summer you dont need freeze protection so run more water. you'll see your temp numbers spike, because the water boils faster- but the thermostat will open sooner allowing a cycle.
ImStricken - as you can see, this thread lives on as more of us, or at least me, have ample time at home to show their Rogue's some love. In your statement above, you praise water for it's awesome cooling abilities, but you caution that some coolant is needed to prevent seals from drying out and other reasons.
I've read that a few times, and I keep wondering what a good amount of coolant would be for my car in very hot Miami. We will never reach freezing temperatures, obviously, so how much coolant should I use? Buying a gallon should be more than enough, but would I pour all of it in? Shouldn't I have more water than coolant in the radiator?

If you’re going to pamper, buy the Nissan blue long life coolant on EBay or your local dealership. You can also get the Aisin version which is a close second and slightly cheaper. I got the Nissan version but I did top up with the Aisin version when replacing my radiator recently.
thank you Casper. At the moment, Aisin is more expensive than the Nissan Blue (in Amazon), so I may just go blue. I will keep looking.
