Hey guys I'm new to the forums and just want to say thank you for your insight in advance. I just began the process today of doing some minor TLC to my 1997 F150 5.4 L to get ready sell it. I noticed the Coolant reservoir was low so I added so more water to it before cranking it and noticed it was leaking out just as fast as I could pour it in. On further inspection I noticed the leak looked like it was coming from in-between the motor and transmission on the drivers side. Surely there isn't a freeze plug in there? Has anybody ever seen this or have any idea what this might be?

Thanks!
