So the mechanic couldn't get it to overheat........weird. I picked the truck back up and went down the road aobut 10 miles and there you have it....it was hot. I decided to replace the radiator. I put the new one in yesterday, and haven't had any problems since. I pretty much replaced the entire cooling system with the exception of the sensors. Awesome.

Lean Burn can be a timing problem and a cause of over heating.
As previously stated on the thread ...
"You might pull a couple of spark plugs to see if you have carbon build-up or a lean burn fuel ratio. Carbon will screw up every thing in the engine including the EGR. Lean Burn will cause over heating on the highway."
and check the tailpipe if it’s gray or black it’s not lean burn.
Have a good one.. Don S..
It would be nice if our members would add their vehicle information to their signature (similar to mine) plus add their City and State .
A member in the same town might be willing to drop by and help you with a problem. Or drink all your beer! One took my wife!... J/K

Hello, It has been a while since I posted an issue in
this forum, last time I was living in Fla. Then
Chicago, IL (3.5 yrs.) and now I am in Indianapolis
In. (1.5 yrs.)
This is my issue: While living in Fla I never had a
need for a heather. If anything else, cars overheat a
lot. A mechanic friend of mine, suggested to remove
the Thermostat. And it was without a Ther, from 2004
to 2012, never a lick of problem. But, when I moved to
Chicago (2012), I must definitively did. No hot air
was coming out, not even warm.
Took the Fronti to an AC/ Radiator shop, they
mentioned that the heather coil was not working, but
he could fixed it. Also, he mentioned that I need to
put back the thermostat.
All that was done. And started to get hot air in
winter.
No issues until just about 6 months ago. The water
pump failed, and I had it replaced…
2 months ago, started to overheat, had the truck
completely flush, and still overheating.
What it would do is, pump all the water into the
reservoir next to the radiator, but, will not suck it
back in. It will just push out the contents of the
radiator until the water would force itself out of the
container.
Replaced the Thermostat twice with the fail safe kind.
Nothing. Took out the thermostat, just like in
Florida. It work great for about 3 weeks.
Ok, so I took it to the Nissan dealer, they replaced
the Radiator. And gave me a clean bill of health.
Last night started to do it again. Got a whiff of
coolant, open the hood, and sure enough, the side
container, was full, and starting to spill over. So I
am buying a Nissan Thermostat, as per the Service
manager recommendation. Just to be on the safe side
and after reading the threads, I am getting a Water
pump. I am sure that the mechanic did not use a
Nissan when did the replacement job.

New Radiator from Nissan
Oil is good. No milky residue.
Thinking about upgrading the cooling fan. Does the
fan pulls in air or pushes air away from the
radiator???
Any and all suggestions are more than welcome.

I had a overheating issue with mine several years ago I spent no telling
how much trying to pin point it because I didn't want to believe it was a
head gasket. So I had the head gasket changed and that fixed my
overheating problem apparently it had a hairline crack in the gasket
causing it to over heat and my guess once the engine warmed up that
gasket expanded the crack causing it to over heat when I was at idle . I
would look into the head gasket. I flipped my frontier over on its side
back in 2009 they totaled it I wish I still had it but good luck!

..
praetorianpi...
The cooling fan is thermally controlled to work hard or just spin. It pulls (sucks) the air though the radiator and blows it onto the engine. If the thermal unit built into the fan fails to work correctly the coolant will overheat on warm days.
GOOD LUCK.. Don S..

Good morning supbud / lakota,
Just yesterday I notice after reading several post,
and it should have downed on me this fact, that the
fan is not working... Fronti rides cool, but after 200
miles of highway driving I start driving in city, it
tents to start overheating. So to cool it down, I
start driving over 35mph....... and top off the
antifreeze.
That alone should have been a red flag. So after
driving home yesterday, and then thru my neighborhood,
the temp gauge went to normal, so I cranked up the AC,
and it went a bit higher..... I looked thru the grill,
and the fan was standing still....
I just ordered a high performance fan for my '00
Fronty.
On a side note, I am on the process of insulating,
sound proofing the cab. Went to Second Skin Deadener
web site, and purchase some Overkill Pro, and some
Damplifier Pro.
Have half of the truck done, and I can tell a big
difference in the interior temp, sound and
vibration....
Again, thank you and will keep you posted as soon as I
am done with the fan.

Hello,
After a couple of very busy months at work, I can post
what I've found.
Even without the thermostat I am overheating. It just
pushes the liquids to the over fill bottle on the side
of the radiator. It does not sucks it back to the
radiator.
Now, as I understand, if I have no Tstat, the water /
anti freeze, should just continuously flow, but it
would appear that something is clogging it.
I can drive in the city traffic all day, no issue.
As soon as I have about 30 minutes of highway driving,
at about 75 mph and start to slow down, the temp
starts to go up, and I have anti freeze all over the
block from the over fill bottle.
So far;
New Hoses. (from Nissan)
New radiator. (from Nissan)
New Clutch fan. (from Nissan)
No Thermostat. (did not make any difference when I had
it). it was from Nissan
I do hear a bubbling sound under the Passenger side of
the dashboard..... not a clue what that is...
Also, about a year ago I had one of those windshield
Displays that connects by way of the ODBC plug, could
that have corrupted the fronti software???
Just grasping at straws....
Thanks
