Let's Play...Name That Part!

Unsure of what I am looking at here.

on a 24 V. Behind the alt on the block,an angled hose of some sort?
It is probably OE on my '00 and is pretty cracked and worn. Need to replace...

Thanks!

Coolant jumper from block to transmission Cooler?

I believe that is the supply line to your heater core but can't tell 100% from that picture.
If you follow that line where does it go? Through the firewall?

If that one's cracked, I would change all of them, including the straight ones (5/8.) There's several in my 12v. The only one I haven't changed is the one in the back of the block. I'm almost certain this is the one at Geno's Garage.

Just so everyone knows. I was under the hood today on the 99 and it is the line for the heat exchanger.
