Okay so I have the truck listed above 3500 four-wheel drive and it has the 454 Big block in it, and I was just wondering what lines came off of the radiator because I know you got a two main water lines an inlet and your outlet and then you got your four metal lines two on either side. I was just wondering what they are called because I'm trying to change my transmission cooler lines and I was sent the two lines that are on the left side of the radiator if you're facing the truck, but I need the two lines that are on the right hand side of the radiator if you're facing the truck. I was wondering what those are called. Thank you

Hi,

If you are standing at the front of the truck, on the right side of the radiator are the lines for the engine oil cooler. Is that what you needed to know?

I attached a pic below showing the lines I think you are looking for. Let me know if that is what you needed.

Take care,

joe
