A/C Evaporator Replaced Due To Leak

[Jimayy]

I wanted to see what the problem and cause was. So, having nothing better to do, I took the assembly apart...

Note the discoloration.

These coils are mass produced and someone's quality control (if they have one) didn't show up.
Ford apparently got away with a recall.

I think other threads or places said it was a supplier issue and the batches or so were bad from that model/part number. So supposedly 2017 models didn't get it as much as 2015 and 2016s. Did it make recall? Or just get a TSB for the issue? I couldn't remember. Just glad we're not to worry about this for a while. Now don't forgot your back-up camera harness! =)
Still, not as bad as the Nissan CVTs being all jacked up on certain models I guess.

Mindo398, Thanks for the amazing write up. I am getting ready to tackle this with my son when he gets home from school.
Question, I notice you have the whole evaporator assembly. Is that to make sure it goes back together well with less chance for fitment issues or mistakes? On that same topic, I have researched your part # and see that the last letter or few letters change from one place to the next. Is that upgraded part/parts that hopefully have addressed some of the weak spots on the core?
Thanks!!!

We decided on the whole assembly due to the age of the car. There's 4 actuators for the dampers, and the logic was if I were to only change the evaporator core, what if the heater core or one of the dampers went out... they're not easily replaced. I suppose your local Ford dealership parts department can assist you with the part number. I don't know why it's different. If you look at the O Ring kit label, you'll see where I got my parts... Read Jimayy's tool list and the other guy's posts, too. They were a big help in preparation.
