Which is supply / return for heater core?

[vnapple]

Guys, which hose is the heater core supply line as I look aft on my '03? Is it the left or the right hose? The illustration in my shop manual shows a different configuration than what my truck has, so I am not sure.



Thanks in advance,

Vinny

To the best of my knowledge, the supply line comes off the cylinder head to the heater core.

Thanks man. That makes sense to me from looking at my truck, but that is opposite of what is in my shop manual. Thanks for the the help!
