High Temperature Warning

[GhiaFan]

Might be worth checking if there is problem with the Active Grille Shutters

Not always. If the thermostat is sticking sometimes (opening at a higher temperature than normal), it can give this illusion of overheating/rapid cooling as well.

However, a faulty sensor or grill shutter issue posted above is more likely.

Thanks for the reply's.

Just to clear things up... My car runs perfect. No problems what so ever, even when I get this spike. No burning smell, no weird noises, no heat if I turn off the A/C. I do get an ozone smell from the A/C, but this always happens when I idle for a bit.

Last time I took my car in, the dealership told me they replaced some items, but when I questioned them further they admitted they didn't do anything. It seems they had some ideas what the problem was, but couldn't replace anything since they couldn't replicate the warning. I was pissed to say the least. Then they tried to charge me for a week of a rental car since they couldn't charge anything to Ford.

I like the idea of a faulty fan, it makes the most sense. I'm going to try my luck with a different dealer (benefits of living in a big city), and see if they can reproduce the over temp.

Can a dealer charge Ford for repairs based off of my video, or do they have to do it in their shop?

Hi HammerStriker,

I want to do some research and see how I can help. Drop me a line via PM with your VIN, preferred servicing dealer, mileage, and daytime phone number. I'll start investigating.

Think this can be partially ruled out in your case though...So my question/suggestion is, when the overheat light comes on, does your fan sound like a tornado in a trailer park? It should still be at max if the gauge is anywhere above normal, and if not, that may be your culprit.

Any abnormal steam, sounds, smells or car actions(other than gauge)?...

The problem is this kind of stuff shouldn't be diagnosed remotely on an Internet forum. We need the dealerships to step up to their responsibilities.

Yeap that's what I meant to say, I'm not to good with car terms and plus thats what the technicians had wrote on their report.

Thanks Crystal, I sent you my info. Let me know if you need further information.

That is not the problem I am having in this thread. I was specifically asking for the help she's providing. Please find a Ford rant thread, there are plenty to choose from. Thanks.

If they wont fix it i say pound it long n hard and when they have to replace the engine you can say..."I told you there was a problem".

That is my whole thought process. I've had my share of clunkers that overheated. This is not exhibiting any of those traits. That's why I just keep driving like nothing is happening. It is very worrying though.

I said nothing against Crystal. I was echoing your sentiments that the dealer is falling short. You said the dealer told you they replaced stuff and they didn't and that you were pissed. So telling me not to rant is a bit of the pot calling the kettle black IMO.

[HammerStriker]

I didn't read it like that...
