Sounds like a different issue.

Thanks for the info guys!
I just don't see a clogged radiator on a car with only 17K on it....but always possible I guess...

At least I now know how to onitially deal with it if/when it happens again.

Apparently GM has never acknowledged or addressed the issue?? Recall??

Update... zero issues since adding the Z06 fan assembly with new control module. Driven 3-4K miles since.

Thanks for the part number and information. When I searched the part number I was able to find the Performance Radiator fan here: Link

When you say new control module, does that mean you had another part replaced or is it included in the fan assembly in the link? Do I need to buy anything else?

Just happened to my brother yesterday in his 2014 ...... Car overheated after a 30 min highway drive and then stop and go at the chik-fil-a drive through. It did the weak battery thing too where it wouldn't restart. He left it overnight and it started up fine this morning.

No... the fan control module is part of the fan assembly. It's in the end of the wiring harness... it's the plug.

I just wasted my time and money. I went to the dealer and had them check the cooling fan and controls. Nada, Zip, Zilch! Everything tested out perfect. I can buy the part for $320 and do it myself but damn, that's why I have the extended warranty.

This is a PITA to get covered by the warranty. There's no friggen way I can get the car to the dealer while its having the fan snit and not do damage to the engine.

As I said, on the Hot Rod Power Tour a team of factory GM techs were there and put my car and another gentleman's 2014 with the same issue through all the tests with the Tech II. Both cars passed fine, but come off the highway and the fan won't turn on. Never get on highway.... works fine.

Just pony up and buy the newer fan assembly and enjoy the car.

Well, I just looked into my Helms and to replace the fan is an electrical connector and 2 bolts, IN /OUT. Have to remove the 4 bolts to get the air intake shroud off, remove the air intake from the TB and Filter and you have full access to the fan. The coolant hose is attached to the fan shroud but it is connected with 2 push pin type of attachments so they'll pop off.

Screw this whole thing. I just ordered the part and I'll do it myself in my garage. I might even take pictures of the project for the timid of heart who are afraid to remove a screw here or there. IT really looks easy, might eat those words but what the helll

It's easy... but you're replacing the entire fan assembly with shroud. You remove the duct to the hood vent, the air intake tube, and the coolant hose support. Then you unplug the connector (has a red tamper proof safety lock tab) and take the entire fan assembly out. Then reverse.

That's what I thought I said? Oh well, I got beer in the fridge and I'm retired so there's no time constraint. Just git 'er done.

Sorry... I read it as you thinking you had to swap the fan and fan motor assembly over. It's easy... just one part.

I would like to do an electrical "autopsy" of your bad fan motor/module. If possible, can you remove the fan motor from the shroud (so it is easier to ship), and ship it to me? Send me a Private Message if you want to do this, I will pay for shipping.

Joo want my freaky fan/controller? Joo got it! We can work this out. It would be great to find a "fault" that can be pointed at to get this issue covered by GM or warranty.

Awesome. Thanks for the info. I'll have him order it. Sounds like an easy fix, although not super inexpensive. I think it will be a good mod regardless. More cooling is always a plus. Even though he drives like a grandpa in it.
