So I just recently returned home from work after 15 days and when my wife picked me up I Noticed I could smell coolant around the front end, level was a little low so I topped it now. Now this morning when backing out of the driveway I noticed a small puddle on the ground. I've looked everywhere and can't seem to find where the leak is coming from, crawled under the truck and all I can tell is that it's dripping around the front diff. Anyone have any ideas of where it could be coming from? 2011 5.0

Thanks

 

Just noticed same yellowish prestone in snow on my 2009 xlt.
will have to check that out this week.

 

Check the plastic elbow on the overflow tank OP. I have seen posts of leaks from there.

 

I have checked there, looks bone dry. I have just been doing some more reading and am about to head out to check the drain plug on the engine block itself, some said that could be leaking but I have to find the location before I go out and freeze again.

Thanks

 

I had a slight misty spray pattern on the plastic below the lowest pulley on my 5.0L. Turns out that my water pump had a slight leak and was replaced by the dealer.

 

I have had the same problem on my 2011 F150, and the part I think I need to fix it (hopefully) just came in today. Mine appears to be leaking from the T-fitting that is between the hose going to the top of the radiator and the water pump. There is a O-ring between the hose and said T-fitting, so I am hoping it is that ($9) instead of a crack or something in the actual fitting ($95) but I got it just in case. The O-ring is part #8590 on the second picture, and the t-fitting is #8566. I am planning on tackling it within the next few days, so I will let you know the outcome.
