wannabe... sounds 100% like you got a couple of air bubbles and/or failed T-stat. You give a lot of details but a good part of it doesn't help. Pretty much idle= cool/warm air and off-idle= nice hot air.

It does sound like air bubbles, but if the coolant has never gotten low, I don't understand how you would have ended up with them ![Dunno](https://g35driver.com/forums/images/smilies/dunno.gif)
On a side note... you are setting your hvac on recirculate, right? Obviously if you're pulling in fresh air at negative temperatures, there's no chance it will heat up to 90 degrees with the fan pulling it through the heater core full blast.
I assume you know this, just have to cover all the bases.

He could of messed something with it or replaced something. A lot of times people replace radiator caps and cause a bubble or 2. doing those samco hoses or w/e is a big possible air bubble thing. There are many reasons why an airpocket in the coolant can form that some people just dont realize. our cars are too new to say part failure aside from a stuck T-stat.
That is something he shouldn't be fixing in this weather in the parking lot tho. Just live with it for now. To me it does sound like air pockets/ t-stat failure but then again it doesn't... I would start off with that possibly consider replacing the T-stat, cheap part, should be easy DIY plus gal of coolant. Again... not worth it to do it at your school lot. Go home on your winter break and handle that.

^ There is a hose in the back with a Philips type screw on it. Near the ATF DipStick. But to the left of it, if you are looking at your engine straight on.
Thats the bleeder. But I have no idea how to do it.
I think you need to have the car on and once coolant starts spilling out you need to close it fast.
dont quote me, I really have no idea lol

I know of that hose but i didn't bother to read how it exactly works.
How i get rid of air bubbles is simple, with a cold engine. I pop off the radiator cap, start the car and leave the heat on full blast hot. Let the car get up to tempature. Your coolant will spill out off the radiator where the cap is, thats fine.. if you have air pockets you can see them come up to the top. I normally run the engine for 15 minutes and just watch it overfill, once you stop seeing bubbles you should be good to go.
Always make sure of your overfill tank is filled up while doing this or it can created more bubbles.
I understand that purge valve in the back can be used to remove bubbles/pockets too. I dont know how.
If you take it to the nissan dealership, they will recommend you do a coolant flush for $129-$159, and this is to "ensure we get rid of all possibly air pockets" bet you they will say this..
