placing this in the General maintenance but if it needs to be moved that's fine. noticed that my X hasn't been heating that well lately. (no heat at idle, taking a lot longer to warm up then usual) and wasn't sure if it was due to the -40*c ( with wind chill) temps that we have been having lately so I took a peak in the overflow tank and in the radiator, both were pretty low, so now is the question. what antifreeze to use? I know I want a pre-mixed one cause I don't want to be standing outside for longer then I really need to at these temps. should I just go with the general all purpose green prestone pre mixed? should I avoid it? any advice is appreciated.

Just buy 100% antifreeze and mix it 50\50 with water in another container inside of your house. Old milk jugs or something work just fine just be sure to mark it and keep it away from food so someone doesnt use it by accident. You could also mix it a little more concentrated due to your temps and go like 70/30 or so of course the antifreeze being the higher amount.

I will just post these up here since most people don't know that a 50/50 ratio is not the best. Growing up where it could get that cold we always tested ours with a device that my dad owned that would tell you the freezing point.

Depending on the year of your xterra, along with manual vs automatic and if you have done the bypass or not I would go with the nissan blue antifreeze. Might cost you a little more but to me it is a peace of mind thing.

I like the Nissan OE Green stuff, it doesnt have silicate (or amines and borates), its always worked better for me than the neon green parts store stuff.

I would just recommend looking into the causes of the milkshake of death as this is for a 2nd gen. If I remember right and it has been a while since I've done a bunch of reading on it. This is one of the main reasons why they switched from the OEM Green stuff to the OEM Blue stuff. Maybe someone who remembers more can join in.

Question for the smarter people out there: Do you have to mix? Could you run 100% undiluted anti-freeze?

Yes technically you could run 100% anti-freeze just like you could run 100% distilled water. The reason you run a mixture is to achieve the lowest freezing point possible. If you look at the second graph I posted this will help explain that. In most of the U.S. 100% water or anti-freeze would freeze at some point in the winter and expand and mess up a whole lot of stuff.

Ah, I didn't catch that the scale is inverted, got it. Thank you.

I thought that the smod was caused by a faulty radiator intercooler. and to fix the issue Nissan went from using Matic S to MaticJ trans fluid ( might have them reversed) and diffrent materials when fabricatin the radiators instaslled in the newer 2.5 gens ( 2009 and newer there arn't many reports of smod from the people that haven't bypassed). as to weather Nissan has changed out the anti freeze or not I have no clew.

I've heard it was a combination of multiple things that caused it but yeah in mid 09 Nissan fixed it and changed radiators.

To sum it up they changed the radiator, Transmission fluid from Matic S to J, and coolant from green to blue. What was the cause of the issue I don't know but in my mind there is a reason why they switched all three.

The 4.0 will use a little water for some reason.. Mine has done this in the past.. No smod.. This is a typical issue.. You loose heat, check the levels...
