Does anybody have a cooling system schematics for a 2011 F-150 5.0? I have a leak that I can't seem to find anywhere. Thanks in advance

Thank you so much. Hopefully this will help track it down.

Your leak is probably right under the reservoir, I think it's #19 in the diagram. Possibly from the T connector in front, #2. 3rd guess: water pump itself. #16

This is very common and I'm dealing with it right now. I was quoted over $900CDN to have it repaired. They said I needed the hose actually replaced and the reservoir. This blew my mind but I said nothing except "Is this covered by my extended warranty?". I wanted as many new free parts as possible lol. They double checked and it was. What it actually is...most likely...a bad o-ring in that T pipe. An o-ring kit and 4 jugs of Motocraft anti-freeze and you should be in business. I would've done the repair myself if it was not covered.

My truck is in today for the third time for this exact leak. The first two times they replaced the o-rings and connector. Today they are replacing everything again including the reservoir. Hopefully this will fix this persistent leak.

Yikes that has to be annoying. Hopefully they get it fixed for you this time. When the weather get better here I plan to get back out there and look around for the leak again. The rain here has been non stop for weeks. Anyways I'll keep everybody posted on my result and hopefully have some photos to share so others that have the same issue can refer to as well. If they figure it out please let me know that might save me a lot of time looking lol

If it is all warranty, fine. But, you may want to take a look at my sig.

just fixed it myself - new upper rad hose, bypass hose off overflow tank & new tank. 2 gals ford antifreeze & has been good to go ever since.

My leak looks to be coming from a bad water pump gasket. All of my connectors and hoses are dry but I have fresh drops under the WP that sometimes show up on the oil filter, and a seep mark all the way around the WP. Have you checked that?
