I'm not 100% sure of the right name but this is what it looks like.



Under the hood it's easy. You remove the plastic cover, there are a few screws but pretty simple overall.

Then you need to remove 3 heater intake hoses, clamped with 6 mm bolts. You peel back a very stuck in place, thick tuber grommet, and underneath you will find 1 of 3 10mm nuts that hold the IKHA assembly together.

Moving to the middle, in between the 2 wire looms, you will find a second 10mm metal nut which is covered with a bigger plastic 10mm nut and it's like an inch long. Once you remove the plastic nut, you can remove the metal nut underneath.

Moving to the left, you peel back another thick rubber and expose the third metal nut. You can unscrew it right away or remove the A/C lines first. You need to find the Allen key that fits, ot you can use torx 40 I believe.
Be careful, if you A/C system is full, it will empty it.

Once you disconnect the 2 A/C lines and the 10mm nut, you're done under the hood.
