I was kinda exploring in my engine during the process of changing my O2 sensor, and I found a couple things that I would like for you guys to shed some light on.

#1 - Is this the infamous coolant elbow? If so, I think i'm in luck 'cause I knocked on it with a screwdriver and it sounded plenty metallic to me

#2 - I started pushing this thing to the side while trying to get to my O2 sensor, and it just plain cracked in half. No fluid came out or anything, and there'* like a shiny, glossy, black plate of some sort under it. For once, i'm totally clueless as to what this could be...

#3 - This must be some sort of mysterious, car-repair accelerating fuel.

i got rexed

Damn, almost got the edit in time

1, Yup.
2, Sound sheild for the blower motor. Not worth replacing.
3, I heard it slows down repairs....

image #3 is infamous with willwren! :P

just don't mistake it with fuel injector cleaner

It'* kinda cliched (#3) to have one while working on your car, but it seems to be just one of those situations where the two go well together, as long as it'* not too many of them

I see an ignition coil and a SC nosedrive in the first pic, not a coolant elbow.

Yes, that'* your climate control blower motor on your firewall in #2.

#3 is the wrong brand.

bummer. image dump is blocked at work.

me also
