Hello all. I have a 2006 v6 F150 that just started leaking coolant on to the exhaust. I took a look under the hood after searching for about 30 minutes found the leak, it is just behind the exhaust manifold but on the bulk head. There is no hose connected and it seems the connection may have sheared off. What am I looking at and how do I go about repairing this?

 

You sure it's not just water? The photo is real blurry but it could just be the a/c condensate drain?

 

It’s definitely losing coolant as I’ve had to top it up a few times now. Sorry for pic quality injured rotator cuff, it’s difficult to get a clearer pic.

 

Theres nothing in that area but heater hoses and condensate drain , it looks like your heater hoses are intact .
The earlier 4.2l was known for timing cover coolant leaks due to bad gaskets as well as failing head gaskets . In some cases the coolant hydro locked engine and destroyed it .
Better pin it down quickly . If it doesn't want to turn over don't force it or jump it .

 

Take another picture that's not blurry and repost.

 

Photo shows what looks like condensate line from HVAC plenum. Your heater core maybe leaking.

Jimboy Good idea on heater core leak .

 

Thanks for all your thoughts on what it could be it’s still confusing as to what’s leaking. Does anyone have a schematic or pic of where the ac condensate is? I’d best describe the position as on the firewall sitting behind the exhaust manifold 8” right of the heater hoses and down 12” from that point. I’d send better pics but my rotator cuff has ripped. Are there any freeze plugs in the firewall?
