Moving to Arizona in a couple of years, but want to get my X ready before the move. Any idea on a quality 4 core replacement for a 2011?? :scratch:

Koyo makes one as well, at a fairly reasonable price, part no. A2807. It is a 2-row radiator.

I am not aware of anyone making a 3-row or 4-row radiator for an Xterra and I doubt there would be enough clearance to fit anything more than a 2-row unit.

Considering Nissan has there proving grounds in Arizona. The stock cooling system works just fine even in this miserable heat. Doing an upgrade on such a new vehicle would probably make something else worse and now you have problems that could have been prevented by simply leaving things alone.

The money is better spent on window tint.

i would get some tech line coatings 2,000 ceramic paint for your exhaust manifold.... and i would also do some ceramic window film on your back windows and llumar winshield film... you can get the whole package of special tint at tintzoom.com then have a local mobile installer come out and install it.

I just noticed that your X is an '11. That is after the "SMOD years," so there is no compelling reason to change anything in your cooling system.

If, after you move to Arizona, you experience cooling issues, that would be the time to address the situation. In the meantime, change the coolant at recommended intervals with the proper coolant and just enjoy your X.

Given they run Xterra's in the middle east with out issues you shouldn't need a radiator upgrade for Arizona. If you're having heating issues where you live now then you might want to consider that there is something wrong and get that checked before replacing the rad.

Thanks to all of you for the info, just don't want it to cook ya know. Window tint is a great idea and is on my list. Now onto a front bumper or bull bar and lights :). thanks again

have you tried/considered using Redline's Water Wetter?

I use that here in the heat of wichita falls in all my vehicles and keeps things cool. I especially notice it on my motorcycle as it has a digital water temp display. typically 15-20 degrees cooler with the water wetter/distilled water mixture. (no coolant at all)

I suspect the thermostat wouldn't care how large the radiator is or what additives are in the coolant. You will probably still see 190-205 degrees on the coolant temp, which is within the operating range. The factory cooling system is very capable of doing the job. If you feel the need to replace, the Koyo part that Robert mentioned above is a direct replacement, no modifications needed. I know of one Koyo that replaced a factory radiator earlier this year, and it has undergone rigorous testing and monitoring all summer in the southwest (including AZ). I have only received positive feedback about it.

I've put 150K on my X working in the desert with zero cooling problems at all. I'd save the radiator money for something else.

Another option (one that I have personally done on race cars & plan to do on my '13 PRO-4X) is to cut the hood, carefully, and add vents. I try to put some wide one's side-by-side just behind where the radiator is and do two more long one's closer to the firewall, directly above the exhaust manifold. Works wonders at releasing trapped heat with no other upgr

uh oh, you're about to get yelled at for commenting on a 7 year old thread. Not by me tho, I'd never point that out.

I have never heard of any overheating issues on and Xterra as long as there are no other mechanical issues. Sounds like a solution looking for a problem that doesn't exist.

I like it when people revive old threads. Keep the info in one place makes it easier to search.

As for cutting holes in your hood you would then loose the benefit of the fire smothering hood liner. Your rig - your call - just everyone should know what that thing is there for. A daily driven truck and a racing truck are different animals. I truly don't think under hood temperatures are a giant issue with the x in normal use - even in hot climates.

Probably not relevant to the X but some vehicles the airflow under the hood is actually part of the cooling system as it allows airflow around the engine and exhaust as well as a low pressure zone to pull air through the radiator and out the bottom. Cutting holes in the hood can actually prevent this designed airflow.

I would agree the hood louvres do look cool.
