I've read that the average MPG is a running average until it gets about 1000 miles in its memory.

Ans in tires & wheels forum

235-75/17 was the smallest OEM tire offered.

$80. Believe the Ford technician said the synthetic oil retails for $40/qt (or something like that) which was why it was so expensive. Better that every 30k than a new unit.

In what field? As most of us know, a PE stamp only covers the discipline you tested in. In all other areas you may not know shit. (I'm not trying to be mean, but stating that you "at least as smart", is somewhat a rediculuous statement. Unless you work for an automotive company, or in a related field, your just a layman like the rest of us). A license does not make anyone an expert. Experience does. A license simply means one has demonstrated the minimum qualifying expertise in a particular field. The reason we trust the engineers at Ford, is for their expertise in automotive engineering. They have to consider hundreds of varables and have knowledge of the history of their particular area. Unrelated, I worked with an automotive engineer who worked for Bendix Automotive. (He was also one of the engineers who had a hand in the Lunar Lander). The experience I gained from him could fill a book. There are so many small points of knowledge concerning each individual part, making up the whole. For example, we spent two hours talking about one screw, the forces affecting it, the shear stress on the thread tips, etc. We don't run your tires underinflated, not JUST because Ford tells you not to; we do it to maintain stability in turns, to prevent overheating around the chords (and subsquently failure), to prevent short life of the treads, to improve braking distance, etc. etc. There is simply no good reason to run tires on low pressure. The soft, squishy ride you get is detromential to the tire, to the suspension and to the car's ability to recover from high speed cornering. It's one of the reasons the feds mandated in the FMVSS to have low tire pressure warning indicators. Lower gas milage certainly, but for all the others reasons as well. BTW, your the first Professional Engender I've met that bragged he was an expert in Automotive Engeering. Every other PE I've ever known in the field were always quiet as to how much they knew. I would guess it's because it's such a large, complicated field. Question: would you, as a Professional Engeneer, feel comfortable stamping a design for running 36 psi on an auto designed to run at 44 psi? Would you be willing to take the professional responsibility for underflated tires?

What about the navigation module, GPS module and GPS antenna? You saying you don't need the extra hardware?

He's driving a 2015.

If Ford calls for 44 psi and your running 36 psi, your wasting gas, wearing your tires out faster (they run hotter and heat causes heat) and throwing off the alignment. Not to mention loss of traction (especially in cornering) and stopping distance. Remember also that pressure drops 1 psi for each 10°(f) drop in temps. If you set pressure at 36 at 72°, you'll be running 32 psi at freezing. Far too low for safety. Should always maintain the sticker pressure in tires.

You mean lifetime of the car (however long that may be - 50 years?) or so long as the car is in warranty? I serious doubt Ford will ever define lifetime publicly. They have to stand behind their warranty, if the defined lifetime as being beyond that, it would extend the factory warranty. So lifetime is only as long as the factory warranty.

By lifetime, Ford didn't mean the lifetime of the car, it means to end of the factory warranty. If you read the owners manual, it also requires you to change the fluid anytime the ptu is submerged and when used in "special operating conditions". In my manual it's 60,000 miles for cars used to tow a trailer, cars used that have a lot of idling and/or lots of low speed driving, operating on dusty or unpaved roads & cars operated in off-road conditions.

Does the screen have the word "Navigation" then yes you have maps and GPS. If it has the word "Information", you don't have navigation. But it can be added for $800. https://www.4dtech.com/15-ford-edge-navigation-kit-for-myford-touch-systems/ Sync services is not related to navigation. It is a method you can use with your cell phone to control certain functions of your car, like remote start, things like that. You must have a contract with Ford and pay a monthly fee. Like GM's OnStar.

Wow, that's distinctive, bet you get a lot of complements.

Believe that you will find the following site has a lot of information and harnesses to convert to aftermarket head unit. http://www.installer.com/cars/by_car.php?carid=7966

It would take a lot more light to add sufficient visibility. If it were me, I would pour a turn around pad and not try to back such a long distance. 12ft x 20ft should be sufficient (3.7 x 6 m) A quick and cheap fix (less desirable however) would be to just add reflectors on stems (about 2ft high). When backing out at night, they should provide sufficient information as to where the edge of the drive is.

Inasmuch as the booster has a 150,000 extended warranty why not have the dealer do it. (Btw, has the diaphragm starts to tear, the booster starts hissing, pedal get spongy. Only gets worst, might as well have it changed).

Well that's certainly scary. Good thing they found it.

Air miles. Each air mile is equal to 7 ground miles.

Btw, how did you determine that the GPS antenna was bad? I don't believe they fail very often. Did you try a radio reset? Don't know how it's done on the aftermarket radio, but it sometimes resets a radio with a glitch and fixes it.

It's a pink connector on gen 1 radios, but in the gen 2 (MyFord Touch) I believe it's bundled in the main radio harness (sorry, misunderstood, thought you had a gen 1 system and looking to add a nav system. Not necessary in gen 2 systems, already there). In gen 1 it's located above the radio, below the center speaker. As it's standard on gen 2 systems, I'm not completely certain. It needs to "see" windshield but will be located inside the instrument cluster. I would guess it's still in back of and above the radio unit.

Not a pink wire, it's the pink connector. It's located above the radio, below the speaker in tbe instrument cluster.

Youtube video, guy shows how you have to come in from the back side on the passenger side.

Just out of curiosity, what's the battery voltage? Someone else in the 150 forum reported the same problem went away after he put in a new battery.

Billy, I have a 2009 MKX with 20" wheels and a T165/80D17 spare. The car had originally come with 18". (Don't know if they used a 17 with factory 20" wheels or not, but based on the size of the spare storage well, it's probably standard). I've used my spare a couple of times without any problems. Rides hard, noisy and rough, but it is what it is. One thing that may have contributed to your problems, and I seen this first hand on mine, is the pressure in the spare. Tire states to inflate to 60 psi. When my tires were getting to the point of needing changing, I remembered to check the spare's tire pressure. It was low, way low. (Probably had not been checked since the car left the factory). I plugged in the air compressor and brought it up to 60 psi. It was the very next week when I picked up a lag screw and had to use the spare for the first time. Did you ever check your spare's pressure? I would have your local Ford garage check to car over and see if it's the tranny sensors or PTU failure. Whichever it is, can't rule out the age of the car, service history (did you ever drain and refilled either the PTU and transmission with fresh fluid)? If you don't do the service, you can expect the parts to fail. Anyway, was just reading a post where a forum member was going to buy a PTU online for <$600 and have a local mechanic install it for jus a few hours labor. (Think it was three, but may have been five. Still cheap considering ...) Either way, you could get the problem fixed for under a grand. If you go the Ford garage route, they have a credit plan (which I use all the time) where you put the bill on Ford Credit, take a year to pay it off WITH NO INTEREST, and get a check back in the mail if over $200. They can sign you up at the service desk. Good luck.

Really? I've never seen a single mosquitoe in Arizona. (We own property up near Sedona).

Wow, great deal. If I were you, I would also consider asking him to drill and tap a drain in the replacement PTU. Still have to drain and refill this unit in the future.
