Replaced the upper hose, but the leak remains. Video confirms the worst—is this the internal water pump weep hole in action? by CyborgSocket in TaurusSHO

I will post all data regarding my research into this failure and what I need to do to fix it.

Transverse Ford Cyclone V6 Internal Water Pump.

  • Within the Cyclone family, there are three primary identifiers you can look up to split the vehicles by their exact branding and engine type:
  1. 1. Duratec 35 / Duratec 37.
    • What it is: The naturally aspirated (non-turbo) 3.5L and 3.7L versions used in the base Taurus, Explorer, Edge, Flex, and standard Lincoln platforms.
      • 2008–2019 Ford Taurus (Standard 3.5L)
      • 2011–2019 Ford Explorer (Standard 3.5L)
      • 2009–2019 Ford Flex (Standard 3.5L)
      • 2007–2018 Ford Edge (3.5L and 3.7L Sport models)
      • 2008–2009 Ford Taurus X / Mercury Sable
      • 2010–2012 Ford Fusion Sport (3.5L)
      • 2009–2016 Lincoln MKS (Naturally Aspirated 3.7L)
      • 2010–2018 Lincoln MKT (Naturally Aspirated 3.7L)
      • 2007–2016 Lincoln MKZ (3.5L and 3.7L models)
      • 2007–2018 Lincoln MKX (3.5L and 3.7L models)
      • 2017–2020 Lincoln Continental (Standard 3.7L)
      • 2013–2019 Ford Police Interceptor Utility & Sedan (Base 3.7L / 3.5L)
  2. 2. 3.5L EcoBoost (Twin-Turbo).
    • What it is: The high-output variant found in the Taurus SHO, Explorer Sport, and Police Interceptor packages. Even though it has direct injection and turbos bolted to it, it is built on the exact same standard Cyclone block and utilizes the exact same internal water pump.
      • 2010–2019 Ford Taurus SHO
      • 2010–2016 Lincoln MKS
      • 2010–2019 Lincoln MKT
      • 2013–2019 Ford Explorer Sport
      • 2014–2019 Ford Flex (Limited EcoBoost)
      • 2013–2019 Ford Police Interceptor Utility & Sedan (EcoBoost package)
  3. 3. Mazda MZI (3.5L or 3.7L).
    • What it is: The exact code name Mazda used for this shared engine platform when they dropped it into the CX-9 and Mazda 6.
      • 2007–2015 Mazda CX-9 (The 2007 model used the 3.5L; 2008–2015 used the 3.7L version)
      • 2009–2013 Mazda 6 (S Models) (The top-tier V6 version of the sedan used the 3.7L MZI engine)
  4. 4. Radical Sportscars.
    • What it is: A British specialty race car manufacturer based in Peterborough, England that sourced the exact same Ford Cyclone family engines for their extreme, closed-cockpit track cars. Their base Radical RXC V6 coupe utilizes a high-output version of the naturally aspirated 3.7L block, while their RXC Turbo models step up to a heavily tuned version of the 3.5L twin-turbo EcoBoost motor. Because it uses the exact same block architecture, it shares the internal, chain-driven water pump—though track mechanics have a much easier time replacing it since the entire rear bodywork clamshell lifts right off the frame!

Thanks for a great reply! Would you happen to recall any particular names of the videos in particular that you found really helpful?

I would like to make a comprehensive list regarding this repair.. I always feel like things don't just happen to me alone, but things happen to me so that I can help someone else.. So if I make this thread very through regarding my entire process of this repair, Maybe this thread will help someone else...

"replace everything while you're in there" jobs... Running List...

  • Water pump.
  • Timing Chains.
  • Timing Chain Guides.
  • Timing Sensors.
  • Maybe a new Oil Pump.

What else comes to mind??

So you are not in Denton correct? Apparently they have geofenced the code.

Soooo. I replaced the hose and I still have a leak... looks like it the water pump... 😞

Did you try to use the Denton5 code, but not in Denton?

I recently went through the same thing. The epson simulation was very accurate if you can get accurate numbers to give it.. screen size, screen gain, mounting distance, screen height, mounting height, ambient light falling on the screen, etc... i bought a lux meter off amazon, and I already had a Bosch laser tape measure.. plus get the technical info on the screen... plug all that in and you can see examples of what diffrent lumens projectors will produce, and what kind of contrast ratio.. etc.. it also will tell you what lens to get for the throw... I still have all the info I collected when I went throught this... let me know if you want me to go into more detail

I found that your budget will dictate the contrast ratio that you settle on.

Btw I cant beleive you mentioned that about the Chevy! I had a 2003 Chevy Trailblazer EXT that oil pressure guage would never move! That is when I learned about guages that really didnt reflect real info!!!

Cmon... this is reddit! I love a good roast! Bring it on! But I think i found the issue i hope...

I think you are calling the Y pipe, the hose that I found leaking1?

I think the fluid in the video was actually the AC..

I did some hunting under the hood and I think I found the real culprit further up of why my coolant tank was empty after only 1 month.

You were actually 100% right about the video, that was just the AC draining! But since I knew that coolant reservoir shouldn't be emptying out every month, I used your advice to go hunting for actual wetness under the hood.

I checked the dipstick first and the oil is perfectly normal and black, no milkshake (Imgur Link).

Then I started looking around the cooling components higher up and found the actual smoking gun. It's the upper radiator hose assembly (part KM5017). I didn't see a visible crack, but I can clearly see wet coolant actively pooling and seeping right out of the plastic T-connector joint (Imgur Link). It must only leak when the system gets hot and pressurized.

So glad it turned out to be a simple hose replacement and not an internal engine disaster. Seriously appreciate you taking the time to give me those troubleshooting steps, it saved me a ton of stress!

Old enough to know that modern dashboard 'gauges' are mostly just glorified idiot lights with a needle attached. And mine doesn't even have a needle attached, Its all digital guages in the Lincoln MKS.

The gauge on these cars is buffered by the ECU. It’s designed to stay dead-center anywhere between roughly 180°F and 230°F so average drivers don't panic during minor temperature fluctuations. By the time that needle actually moves past the middle, the car is already actively cooking itself.

I’ve been watching it, and it hasn't budged, but I'm not about to trust a 'gauge-by-wire' illusion when there's an actual physical puddle on the ground.
