Pulled this from a different forum where they reported same condition after change. Quote: Ambient Air Temperature Sensor The Ambient Air Temperature (AAT) sensor contains a thermistor. The sensor varies its resistance with the temperature. As the temperature rises, the resistance falls. As the temperature falls, the resistance rises. The Ambient Air Temperature (AAT) sensor is an input to the PCM through separate input and return circuits. If the outside air temperature is below approximately 0°C (32°F), the PCM does not allow the A/C clutch to engage. After replacing an Ambient Air Temperature (AAT) sensor, the sensor data must be reset by either driving the vehicle at speeds consistently about 20 MPH for at least 5 minutes to update the filtered data or perform the multiple button press reset procedure to update to the current raw value. On the HVAC panel controls, press the A/C and Recirc buttons simultaneously, then release both. Within 2 seconds press the A/C button again.

Thank You! Was curious about how the compare with the gen 1 versions. .

or their MKX's. (cough)

On mine, the cooling fans cycle on and off when idling (and going slow, like in traffic when insufficient air flow through radiator). Seat fans (at least on mine) stay on steady when turned on. They don't cycle on and off). Is you seat cooling on when this occurs?

Probably the radiator cooling fans turning off and on as coolant temperature rises.

Can't you measure the pipe before the start of the tips?

Would this work? https://www.amazon.com/dp/B01M028L5E/ref=cm_sw_r_cp_apa_dhTSAbCKTNHH2

What's wrong with going through the dealer?

About the only way I've ever tried was to drill out the spot welds. Doubt you can break the welds.

Interesting, short article on the SAE website about the future of automotive sound systems. Talks about eliminating the speakers to produce better sound & 3D modeling. https://www.sae.org/news/2017/11/sounds-like-holistic-audio-system-development?eid=339052586&bid=1993549

Pull each sensor connector and check for corrosion.

Don't think these pads were designed to fit plastic oil pans anyway.

Well if that's 12k miles, that car has seen a lot of back Texas roads. lol. If you haven't installed it yet, can you slap a tape measure on it and let me know what the dimentions are?

Got curious and checked. You're absolutely right. They are pressurized (my cap is marked 16 psi) and the service manual talks about crud getting between the gasket and how to clean. (Replace if cracked or failed). And if leaking, can cause loss of coolant as OP described. Learn something new every day. Thanks for chiming in.

Looks great! Now you need chrome door handles.

PTU = Puke-up Tactical Unit. It's a black box that sits in the middle of Ford & Lincoln automobile powertrain, that came equipped with an option called AWD (which is an acronym for "Acute Watery Diarrhea") and when the time is jussssssssst right, trashes itself.

Using your analogy, I'm nearly 144 years old.

Service reps come and go, not really important. Their job is to get you checked in and push extra service such as wiper blades, tires, etc. Your best bet to ask to speak the either the Service Manager or a technician.

Believe it was added in on an update, perhaps they just installed the unit without updating the software.

Guess I'm confused. Doesn't the coolant resevoir vent to the exterior? If so, the only function the cap would have is to keep the dirt out. What am I missing, can't seem to see what part the cap would play in loosing coolant?

It's not, it's only a recommendation. One way to be certain is to drain a small amount of coolant and test one or twice a year. The important part is to make certain that the coolant doest go acid as it ages.

Ford builds cars. It's the suppliers who design and build the add-ons. The map software is produced by HERE maps and the DO have a procedure for sending in edits. I've done it twice. In order to just "hit a button" the navigation unit would need to be a full computer, with a specific i/o function dedicated to just this purpose. Used what, once a year? If you go onto the HERE website you will find the method for making edits on their maps. As far as why so long, I called HERE and it's not them, it's Ford. Appearently Ford has decided to switch venders for the map software. But then that's not comfirmed either. .

I buy mine on Amazon. Cheaper and better selection. Normally I buy the ATP brand with carbon. Couple of years ago I went with OEM. On my filter, I didn't see any difference in number of pleats over aftermarket.

One other possibly is to have the dealer do it while it's up.on the hoist for an oil change. My dealer told me they don't stock the foam, but if I were to bring it in, they would spray it into the evaporator drain while it's up there.
