Hi everyone, long time user of this site for information but never posted. I have an issue I'm hoping you can all help with. I noticed the rotten smell of burning coolant in my 2013 f150 ecoboost when driving home from work yesterday. I popped the hood today and think I have located the leak but the problem is I'm having difficulty locating the part I would need to replace it. I'm posting a picture, it appears that the elbow on the heater core line has worn away through rubbing on the cover over the years and is now a steady small leak which is burning on my engine and making me nauseas lol. Any help with this fix is appreciated.

that won't work. That is for the over flow tank not the heater hose connection to the core

OP you need a new heater hose

I thought something looked a little different about it.
