I took pictures and also swapped in a coolant filter kit. Figure about 4-6 hours depending on what you run into. I'll tell you the thing that took the most time... the lower cooler (getting it out), the upper delete plug (it refused to fit), and getting the battery box back in (I had to trim 2 support ribs on it for some dang reason... still can't figure that out. Although, that was b/c it was late and I couldn't bang it in b/c I would've have woke the neighbors up).
That 4-6 hours included swapping the elbow, coolant filter kit install, refilling fluids, and putting up tools.
