Leak
#12
It looks to be coming from the water pump area. It is some sort of of oil like liquid. Definitely not coolant and I am very positive it is not engine oil it is too light of a color and doesn't smell anything like it. My dad took a look at it and We removed the "skid plate" like cover(it covers the power steering stuff) and we could see it was just leaking from the front down. I drove it about 12 miles and parked it. It has been an hour and there is no liquid on the ground as of now.

The water pumps fail a little more often than we'd like on the 5.0, not sure about the 3.7. But, that would be coolant leaking.

The liquid I have is watery looking with slightly yellow orange tint to it and has no odor does that match what your liquid was?

Hi. Its coolant. On the front of the lower intake manifold there is an aluminum nipple (coolant outlet) that the thermostat housing slips over. Behind it there is an o ring. Likely this o ring is seeping. The coolant sits on the top of the block and runs down the front of the motor next to the water pump and to the ground. Depending on how the truck is sloped the coolant could run down the ridges next to the water pump and be hard to see. I had this issue on my 2011 with 3.7. I came out one day and there was a huge puddle under the front left corner. You need the o ring as well as a seal that seals the aluminum housing to the left cylander head. Unfortunately I cannot attach any sort of parts diagram from ford parts But.....
The o ring part# is AT4Z-8527-A and the seal is RTS-1081. I am looking at them right now as I have not changed them yet. Since it has warmed up (I live in Alberta Canada) it has not leaked. When it leaked that big puddle we had a huge warm up from -40 to -19 in a very short period of time. I think its because of the aluminum expanding and contracting. The block is big and the housing assembly is small and changes at much different rates. i also noticed seepage when I plugged my truck in as the block heater is also located in the same aluminum housing as the thermostat on a 3.7. Doesnt look too bad to change,drain coolant, 4 bolts and slide the thermo housing off. Not sure if you have to remove hoses as there may be enough slack. Sorry this is so long. Good luck and please report back.

After it evaporates it doesn't seem to have an odor and just leaves a stain. If its coolant pouring water over it will clean it off 100%. Take a real close look at the coolant outlet as per my last post
