2012 PPV Coolant Leak

[aniwack]

My apologies if this has already been discussed but I am trying to determine what part this is. My 2012 PPV has developed a coolant leak on the right side of the motor where there appears to be two plastic housings on the upper side of the motor. I can’t find an engine diagram to determine what part this is but the coolant will ‘spill’ and vaporize off the engine throwing up a white cloud while reversing up an incline. I’m going through half a reservoir every 2000 miles. Before the local shop charges me a $250 dialogistic fee to glance at my motor, what am I looking at??

Don’t forget the new metal Dorman tees @Tonyrodz recently posted about

Posting a picture of where you think it’s leaking might help us.

Is it where @Doubeleive is pointing or here?

if so, same parts listed above would apply

Silly phone didn't attach the pictures. It doesn't appear to be the hoses but this plastic housing.

I don't see anything of note in the pic. What plastic housing?
