I'm "Technologically Challenged" in the photography department, only got a old regular camera :( so pics would have been horrible. Funny, I was thinking that as I was working on it! I can tell ya the hardest part is just physically reaching the hoses/clamps on the core. I had to unplug the computer harness from inside the car & bring it out into the engine bay to get enough room just to reach them(the harness runs into the car above where the heater hoses hook to the core). The AC is in the way, but you can work around it. Inside, I pulled the computer out to gain a little more room inside. All the electronics that control the heater are attached to the housing, that had to be removed also. There are only 2 scews to take off the housing, then a cover slips out & you have access to the core.
Barely got dirty :o
