    Auto startstop

    If you apply the brake very lightly it won't activate as well. Still a non-issue. Just drive it and enjoy the fuel savings and *quiet* while stopped.

    2010 Taurus SHO rear brake calipers open too far

    95% of the time, replacing the caliper solves caliper retraction issues. Odd that two are though, but it is possible. I'd also replace the rubber lines to the affected calipers and thoroughly flush the system with the correct fluid. Think it is DOT 3 but don't quote me.

    EcoBoost Engines and Coolant Consumption

    I haven't gotten to drive one after the recall. Be sure to post anything odd you notice otherwise. I'm curious.

    EcoBoost Engines and Coolant Consumption

    Before going further, ALL new Fords are shipped at or very near the "Minimum" mark. If you get one shipped to you anywhere above it, be *very* surprised, or someone added when PDI'd. A few ounces less coolant per car times millions of cars adds up and Ford is notoriously tight assed on stuff like that. A side note, The 1.6's with the coolant level sensors had to be set where ever the sensor was happy, and often that was the low end of the marks on the bottle. In answer to your question, YES. Some loss is to be expected OVER TIME as they do weird voodoo in the head on 1.5 and 1.6 to run it hotter, and thus maximize fuel efficiency. They also water cool the turbo. Both of these may create potential for outgassing at the cap. You're not really "using" coolant (it isn't being burned or leaked), just outgassing water as steam and other parts of the coolant due to normal heat cycling. Your Fusion does not hold very much (10.9 qts total) so a very small amount of change is noticeable. And finally, temperature of the coolant causes the level to vary slightly in the bottle. Can't speak as to the statement in the WSM. I never looked for that, honestly. The 1.5 has a LOT of places it can leak externally that are hard to determine. The usual culprits are the waterpump, the totally unnecessary quick connect directly above the transmission, and numerous other fittings. The water pump is tough to diag as the weephole is inside a cavity that can fill and dry up easily without streaking anywhere else, or hitting the ground. Usually some light streaking from the hole, or gooey sludge on the inside of the pulley are the first signs. Keep an eye on it. It doesn't fix a coolant leak. It reduces the possibility of headgasket failure. As I told JTav8r, some loss of coolant over a long period of time is expected due to outgassing. Fact of life with these engines primarily due to how they use the coolant in the head to maximize efficiency. LARGE amounts of change are a problem. Yes. Reprogram is to reduce the potential for headgasket failure due to the design of the block.
  5. It's 52 inches at the narrowest point in a '15 four door. It's 50 inches across my '08 four door. That being said, the most kid friendly car when mine were little was my '95 TBird. Preferred that to the Focus or the Tauruses (95, 02, 03) I had during those years.

    Preferred oil for 3.5 ecoboost?

    Uhh.... Motorcraft?
  7. When my wife got pregnant with our third, she figured out how to get two *and a booster for our oldest* in her 08. It can be done.

    Batter issue?

    The electronics aren't that finicky. Under 8.5ish volts, modules shut down. Been that way since EEC IV in the 80s. No alternator on the planet can stop transients dropping voltage, because it takes a bit of time for the alternator to react. It is also harder to make more when the voltage is low to begin with. To reduce transients it needs physical storage. In other words, It needs 2 batteries, and the OE one is probably failing. It is NOT a warrantable item, as per Ford. Things age. The battery, your plow, alternator, etc. It probably takes just a bit more amps to run than last year and your battery is a bit older.

    Batter issue?

    Test the battery. Then get a copy of TSB 19-2373 to add another battery. 19-2373

    Porosity in Ford Blocks

    ALL new short blocks are of the new design. That is the latest part number. If it had an earlier revision I'd be concerned, but that is the latest available.

    2011 Ford Edge Oil pressure Warning Intermittent Light

    You didn't say what year the vehicle is, but It appears to have Specialty Green in the coolant bottle so that makes it a 2009 to early 2012. So that's what I'm running with. Correct me if wrong. Does the oil appear milky at all, like it may have coolant in it? The waterpump is the timing chain idler, and it can leak internal to the engine. If it does, it can be saved as long as it runs and doesn't knock. Is the check engine light on? Does the engine operate quietly at startup and when the light is on? What type of oil filter and grade of oil are you using? It may be as simple as the oil pressure switch giving up the ghost, but I'd want to have an engine oil pressure check performed, to verify it is not the engine. The switch is a simple on/off switch, screwed into the block near the oil filter. It has a single wire. You can probably DIY a new one in. STRONGLY suggest MOTORCRAFT replacement, if you do. Your pic is the VCT solenoids. Sometimes they weep, not a huge deal as long as the solenoids are functioning ok. The other thing might be that someone missed the oil fill at some point. Typically the 3.5 leaks from valve covers and timing cover.

    Alarm goes off randomly

    What year is your MKZ?
  13. You're smelling it in the cabin? Several possibilities to check, In order. Check for missing/broken hardware on exhaust manifolds, cats, or Y pipe. Check manifolds for cracks. Soot around any pre-cat connection is also an indicator of leakage. Loose spark plugs. Fuel leaks from rail/injectors and EVAP system. Check for missing/damaged grommets, air vents and decklid seal, just as they would for CO issues in Explorer. Make sure HVAC is at latest software level- won't solve issue, but may mitigate it some.

    Black Fluid leak

    Most of the 6F55 transmission's port plugs are in the case end cover (driver's side) and on the bottom. The lowest one in the case is the sump drain, the one slightly higher, still in the case, is the line pressure port. If I remember right, there is one more located near the rear cooler line. The end cover has several. Four, I think but don't hold me to that. But most of those will not pool on top of the trans. I've seen the cooler lines leak where they go into the case as well, but it is much rarer and usually because someone was messing with them.

    Black Fluid leak

    Pooling on top of the transmission or the PTU? I'm a bit confused. If it is pooling on top of the PTU and it is gear oil, the PTU is done. What year and which engine does it have? I guess I just assumed it was a 3.5?
