Do the LS1 and LS6 coolant lines are the same? bolts on?

 

If you are talking about the ones running to the heads then yes they interchange

 

The ones that runs under the intake manifold. thanks.

 

Any comment at all?

 

I believe that the coolant lines are different. That's why you have to modify the LS6 intake when installing onto an LS1.

 

The coolant lines under the intake are different.

 

They're different but so similar that you can use either on either setup. To use the LS1 lines on the 5.3L it will require an ever so slight bend to that line. It's nothing major and it wouldn't crimp it or anything. This is due to a VERY slight different in that area on the head. Nothing serious, run whichever you want. We keep the LS6 pipes/plugs in stock if you want them!

 

Thanks for your advice.

 

They are different. If you are asking because you are doing a swap to a ls6 you can get the ls6 coolant lines and rear block offs for around $10 shipped on ebay.

 

you stole my avatar, dick

 

The way I look at it the more of those avatar's running around, the better.

Using the LS1 lines on a 5.3 was mentioned up above. So there is a little bit of modifying involve in this? Reason I'm asking is I gave my LS1 intake and coolant lines to my brother for a future mild 5.3 build, the more info we know now the better.

 

I totally agree. lol.^ And, yeah they are different but only cus the ls6 doesnt go under the manifold and there are blockoffs for the back.

 

sorry about that. lol. I seen it and had to have it. I have a lot of them but cant use them here. due to size so I would have to make them smaller.

 

no dont apologize the more the merrier. lol. Thats my favorite avatar on this site right now.

 

mine too

 

It's cool just giving you a hard time
