Hello,

The heater core is located inside the HVAC box, which is behind the dash.
In order to access the heater core, the dash needs to be removed first.
It calls for about 10 hours of labor for a shop to do it.
So, it is fairly labor intensive. But it can be done using basic hand tools.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.

Would it be the same for the 2016 LML 6.6 diesel?

One more thing, this will require you to vacuum down and discharge the A/C system, before taking everything apart.
