What year and why are you replacing it? If i see your picture correctly and there are 2 lines one goes into the cooler and the other comes out of the cooler.

Hallo Big Mama ,

You are right i forgot to tell you the car details. It's an 2007 Tahoe 5.3 regular gas LTZ 2WD. And you are right, this are this to lines they goes in to the cooler in front behind of the grill. One is the top Pipe and one is the bottom pipe. I think top one is Ingoing and the bottom one is outgoing.

Thanks for your help greetings Markus from Germany

My pleasure Markus. The parts on line or in the catalog should clearly state which is supply and which is return. I haven’t had to replace mine but I’m assuming you have a leak? If so where?

 

[DJPoertsch]

Hallo Big Mama.. I have no leak at the moment. Only the survace ov the pipes have corrosion. So i want to replace them.
My concern was if I order the right parts. Because with the Dorman product is a valve block with it and in the other two articles, it is only the individual lines. I wanted to have another expert opinion so that I would not order the wrong parts. Because sending to Germany and sending it back is very complicated

The difference between the individual lines and the lines with the 'block' is: the individual lines are for a 4 speed (4L60) transmission, while the other one with the lines connected is for a 6 speed (6L80) transmission.

Hallo @mikeyss

Good you are my hero. I was one step away to order the wrong one. Thank you so much. So i would see that i get the 2 single pipes. Because my Tahoe LTZ is only an 4 Speed transmission.
I am so happy not making an mistake in point of ordering this parts.

Great help from you

I just looked again at the picture with the block with the hoses attached and just realized, those lines are for an engine oil cooler. I'm really glad you didn't order the block one, that one attaches to the engine and not for the transmission.

 

[Big Mama]

Me too. Thanks for jumping in.

Thank you very much... safe money and don't waste time with the wrong parts. Now i start ordering the right parts. Thanks to all here at my post.

Greetings Markus
