I have a 2016 Versa Note with about 68,000 miles on it.

Last month, I noticed the AC was not so cold when idling. Once moving it blow cold. I made a mental note to check it out sometime.

A few weeks later, I was stuck in traffic and saw the red temperature overheat light go on. I shut off the AC and turned on the heat full blast (in 90 degree heat) til the light went off. Once traffic was moving again, it was OK.

After it had cooled that night, I looked in the overflow well and the radiator fluid seemed low, I added maybe a cup of coolant to get it to the line. There appeared to be no coolant leaks anywhere.

A week later, it's overheating again, and I thought I smelled some coolant.

I think the problem is either the radiator fan switch, or the fan itself.

Where is the fan switch located? Is that the same as the coolant temp sensor?

I would double check the coolant level again, You may have added fluid, but there could have been air bubbles in the system.

When parked at an idle running normally or when overheating, does the radiator fan ever kick on?

Can you hear the radiator cooling fan running at any time? It should cycle with the A/C and the noise is quite noticeable on our 2015 1.6 S.

Could be the fan itself is bad. Could be a switch, relay, etc. I'd start by unplugging the fan and put power to it to see if it runs. If it runs well, back trace from there.

No, the switch is not the same as the relay.
The relay is in one of the fuse boxes located under the hood.

DO you have a SES light? If so, grab the code.

Quick fan motor test:
First, WITH THE CAR OFF, can you spin the fan by hand? Does it make any noises or bind when spinning?
If the fan does spin freely, check the relay next.

Thanks all!
I was due for an oil change, so I took it to my local Nissan dealer in Chantilly. They charged $139 for a diagnostic.

An hour later and they reported everything in the cooling system checks out good... except for the fan.

Total for parts, labor and credit for the diagnostic fee is $887.

I told them thanks, but no.

They charge me the $139 and I got the oil change and a car wash for free.

I just ordered a premium fan assembly online with OEM connectors for $90.... $107 with shipping and taxes.

Consulting YouTube, I find someone with same make/model of car and they removed the fan assembly by disconnecting the airbag sensor and about 24 different bolts and pop-out clips. Then you have to finesse the fan out of there and shimmy the new one in and reconnect everything.

I think I can do it in about 3 hours or less.

~$900 repair on a 3yr/old car where this part should last 5x that long.

I know some will balk at the cheap Chinese aftermarket fan assembly, but look how good the OEM one was.

Good for you!

Yes. Certainly disappointing. I was not expecting that kind of failure. Even at 68K miles.

There are actually a couple YouTube videos for the 2016 Versa with this issue. So it appears to be common.

Maybe I'll make a video myself.

Next question would be... should I keep the old fan assembly and look at refurbishing it? Hold onto it for another 68K miles. Just in case.

Maybe build an emergency fan that clips on to the FRONT of the radiator for quick deployment the next time this happens.

I had a fan motor go out on an '88 Escort several years ago and couldn't find a used one and didn't want to put a new one on a car with 300-400K miles at the time. I looked at the fan on a mid-late 90's model Ford Taurus, it was quite a bit different with a larger motor and totally different blades but figured I could remove the one from the Taurus and put my blades on the Taurus motor drill a couple holes for mounting the motor to my frame and cut the plug off and splice it. I think I paid about $10 for the fan out of the Taurus maybe did 30 minutes worth of modifications and it lasted until I quit driving the car several years later with over 500K miles. This is something you may want to try with your old assembly or if it happens again. Sometimes you have to think outside the box.

Some Versa fans have integrated electronics on the fan itself, could be as easy as replacing the relay on one to get it back working..........

I'd keep the old one. It would be nice to just be able to replace the fan motor on it.
Yes. The Nissan mechanic said "In the old days, we would just replace the motor. But these days, they recommend replacing the whole assembly."

I see that the motor can easily be replaced in the assembly. Maybe I can find a more powerful one.

Also wondering if there would be a market for an "Emergency Fan" that you could clip to the front of the radiator? Or would it really have to be blowing on the engine to be of use?

Reason: It takes the removal of over 23 bolts and connectors to reach the fan. If you need a quick fix until you can get a fan properly replaced, a backup fan could be useful. Especially since it only takes maybe 10 bolts and plastic connectors to loosen the grill/bumper to access the front of the radiator and it looks like there is enough room there for a small turbo fan. Just a thought.

I got my fan in the other day. Waiting on a nice sunny afternoon to install it.

Temperatures in my area have dropped, so the fear of overheating is reduced now.

That's a good idea. Was thinking that myself. I'd have to label it and hang it up in my garage for the time when I might need the new fan - Maybe in 10 years?

Or, I might take the fan assembly and build a stand for it, so I can use it to circulate air when I'm painting the house interiors.

Finally got around to doing the install. What a PITA!

Took about 2 hours to get the thing out. Easy part was that 12 or so fasteners for the front frame brace and grill.

Other than that, there were only two bolts down on the sides of the fan assembly and it theoretically could just slide out. But you still have a bunch of hoses to unhook from various clips.
It would probably have been easier if I had jacked up the car a bit to access all the hose clips near the bottom of the fan assembly. I stole the screenshot from a youtube video of the operation.

Also, take a good look at your fan harness before you order. I had opted for the premium fan assembly off RockAuto.com. (around $170). Did not realize it had a single pigtail hock with 4 prongs in it. I needed two hocks with 2 prongs each. the cheaper assembly at $90 would have done the trick!

I ended up going to Advance Auto where they had the correct assembly for $170 and I have to send the Rock Auto part back.

Once I got the correct part, I fussed with it for half an hour trying to get the right side to align properly with the bolt hole. Turned out the alignment was off because a piece of plastic had fallen into the right side clip that the fan tab slides into. I had to use a small screwdriver to pry the obsteuction out and then everything fell into place and had it all put together in 30 minutes!

Next time cut all hose clips, and any other clip on one time use fasteners used. Go the Harbor Freight or Walmart and buy a cheap bag of plastic wireties and use those to refasten any hoses or wiring harnesses. Fan assemblies like you picced there should be able to come out and go in in 5-7 minutes max and never having seen them before. Many lift UP to free them but come out of the BOTTOM of the cars easiest.
