Dino615 Posted September 20, 2016 Report Share Posted September 20, 2016 So my wife text me and said her air stopped working and then called almost immediately and said it died. When I picked her up she said the display told her it overheated. I scanned it first thing and got a P1299. Then I opened the hood and the reservoir was bone dry. First thing I did was check the oil, liked fine. I ran and got a gallon of water and a gallon of anti-freeze. I poured in the gallon of water and waited, nothing. Checked the oil, seemed fine. Poured in about half a gallon of anti freeze and it was finally showing in the reservoir so I waited a minute. The engine ran smooth. After about a minute water Started running out from under the car. Checked the oil and it was slowly getting milking. Obviously an issue. I snapped a picture and a short video before I shut it off. And suggestions? Does this look like a cracked block, or could it be a head gasket? Or is it still just a guessing game?? It won't let me upload the video.

akirby Posted September 21, 2016 Report Share Posted September 21, 2016 Could be the water pump which is internal. Quote Link to comment Share on other sites More sharing options...
Dino615 Posted September 21, 2016 Author Report Share Posted September 21, 2016 Ewww. Ballpark what that repair cost? <$1,000? $1000-$1,500? I'm trying to maybe work a deal on a trade in at the dealership. Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted September 21, 2016 Report Share Posted September 21, 2016 The video should be uploaded to a sharing site like flickr, photobucket, etc then linked back here. How many miles on your MKX? "water" coming out, meaning coolant, right? From the location, it is likely a cracked block OR the coolant xover tube OR the thermostat housing that gave way. I hate to say this, but regardless of the cause (water pump, head gasket, cracked block), you may want to look at getting a low mileage used engine and having that put in instead of attempting repairs. At least figure out if that option is viable for you or not. 1 Quote Link to comment Share on other sites More sharing options...
Dino615 Posted September 21, 2016 Author Report Share Posted September 21, 2016 Yes, coolant/water i had just added. It has 111k miles on it, it was a cool 88 degrees today so she was running the air but just everyday driving. I am not discounting it, but I have never heard of s block cracking in the middle of summer for no reason. What would cause that? Any of the other answers sure sound better to my wallet Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 21, 2016 Report Share Posted September 21, 2016 (edited) I am thinking cracked tube/housing, but I dont know why the oil is turning "milky". Are you sure the oil is simply not breaking down, possibly because the oil level is low? Edited September 21, 2016 by WWWPerfA_ZN0W Quote Link to comment Share on other sites More sharing options...
Dino615 Posted September 22, 2016 Author Report Share Posted September 22, 2016 Well it was water pump and the my wife let it get too hot and warped the heads. Thanks for all the answers and help. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 22, 2016 Report Share Posted September 22, 2016 Ugh, sorry to hear! Dropping in a new engine then? And I wouldn't blame da wife. I think it's just lousy that the design of the water pump makes it near impossible to figure things out until the failure happens. I guess that should be a warning to all of us to change the coolant sooner than the stated 105K miles for the first change. Just not worth the risk.

akirby Posted September 22, 2016 Report Share Posted September 22, 2016 I thought all Fords had failsafe cooling and would shut down the engine before it got damaged? Quote Link to comment Share on other sites More sharing options...

I am trying hard not to blame her, but this is the second car in a row that she has blown the motor on (03 Altima 3.5s), and she said, "well, it didn't want to go so I just kept pushing the gas until it did."

Dino615 Posted September 22, 2016 Author Report Share Posted September 22, 2016 I thought all Fords had failsafe cooling and would shut down the engine before it got damaged? It did try that, but she fought it and managed to let it get super hot and ruin it. Quote Link to comment Share on other sites More sharing options...
akirby Posted September 22, 2016 Report Share Posted September 22, 2016 It did try that, but she fought it and managed to let it get super hot and ruin it. Wow. At least an engine is cheaper than a divorce! Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 22, 2016 Report Share Posted September 22, 2016 Wouldnt call it failsafe, but it is pretty neat in that only 3 cylinders are fired and the remaining 3 are used as "air coolers". I had asked a tuner about having that as an optional economy mode (cylinder deactivation), but was told it's not a good idea. Anyway, make sure your wife gets a non-3.5. Maybe "3.5" is a jinx LOL. 1 Quote Link to comment Share on other sites More sharing options...
akirby Posted September 22, 2016 Report Share Posted September 22, 2016 That's step 1 to allow you to get to a safe place. But beyond that it will actually shut off the vehicle. 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 22, 2016 Report Share Posted September 22, 2016 (edited) ok, that's new to me. Will look it up. EDIT: Ok, I see it in the OM. Here is an excerpt for the 2007 Edge: What you should know about fail-safe coolingIf the engine coolant supply is depleted, this feature allows the vehicle tobe driven temporarily before incremental component damage is incurred.The “fail-safe” distance depends on ambient temperatures, vehicle loadand terrain.How fail-safe cooling worksIf the engine begins to overheat:• The engine coolant temperature gauge will move to the red (hot) area.• The symbol will illuminate.If the engine reaches a preset over-temperature condition, the enginewill automatically switch to alternating cylinder operation. Each disabledcylinder acts as an air pump and cools the engine.When this occurs the vehicle will still operate. However:• The engine power will be limited.• The air conditioning system will be disabled.Continued operation will increase the engine temperature:• The engine will completely shut down.• Steering and braking effort will increase.Once the engine temperature cools, the engine can be re-started. Takeyour vehicle to an authorized dealer as soon as possible to minimizeengine damage.When fail-safe mode is activatedYou have limited engine power when in the fail-safe mode, so drive thevehicle with caution. The vehicle will not be able to maintain high speedoperation and the engine will run rough. Remember that the engine iscapable of completely shutting down automatically to prevent enginedamage, therefore:1. Pull off the road as soon as safely possible and turn off the engine.2. Arrange for the vehicle to be taken to an authorized dealer.3. If this is not possible, wait a short period for the engine to cool.4. Check the coolant level and replenish if low.Never remove the coolant reservoir cap while the engine isrunning or hot.5. Restart the engine and take your vehicle to an authorized dealer.Driving the vehicle without repairing the engine problemincreases the chance of engine damage. Take your vehicle to anauthorized dealer as soon as possible. Edited September 22, 2016 by WWWPerfA_ZN0W Quote Link to comment Share on other sites More sharing options...
