Hello all. I have a 2012 super crew, 4x4 with the 5.0. I have an antifreeze leak. I am guessing somewhere on the back of the engine. It is dripping off of the back of the oil pan and transmission bell housing. It only seems to leak on long trips of about 45 minutes to an hour or longer. I can't get to were I can see the back of the engine very well. where could this be leaking from? Intake? Head gasket. No water in oil and runs at normal operating temp.

 

Need to put a pressure tester on it to pinpoint the leak, that and/or coolant dye and a UV light.
.

 

There is a t-connector on the drivers side of the engine that will leak. The same thing happened to my truck. It took the Dealership a while to find it as it didn't leak until the motor cooled down some.

 

I just dug up my repair order....DR3Z-8566a T-connector and a BC3Z- 8590F seal.

 

that looks similar to my leak, and I only notice it after cool down. Did that leak drip off of oil pan and bell housing?

 

Exactly... at first I thought it was tranny fluid. It was like it would burp overnight after cooling down.

 

I had one of these. Replaced a $.26 oring all by myself in about an hour. Oh, cleaned the throttle at the same time.

 

Thanks for the replies. Hopefully I will be able to fix this soon.

 

Look on top of the front of the engine too. I just noticed coolant on my top pulley so I assume I have a leak from a top hose... Anyone have this issue?

 

That's where i had my coolant leak. People say to replace the O-ring, but i didnt feel like waiting till the store was open so i just used RTV and it has been holding fine for about a year now
