Not sure what it is to search. I have the 4 corner coolant crossover tube. Mine has a small leak on one of the corners, The local auto wreckers has a 2 corner there that he is willing to part with as its a core engine. Can I put that one on mine or should I look for the 4 corner? The 4 is on a 5.3 and the 2 is on the 4.8.
What is the cost of them used?

 

why not just get new o rings and stick with the 4 corner. otherwise to use the 2, you still need to block the other holes.

 

It's leaking where the tube goes into the block that bolts to the head. I was going to get the rear blockers as well. Just wanted confirmation if I should or shouldn't do it thats all.

 

I realize that, there are small o rings that prevent it from leaking...

 

I think he means the actual tube that goes into the block David. The o-rings go under the block between that and the head. The tube might have a hole in it where it comes together with the block at the end.

 

Aw thanks for the clarification scott. in that case just go with the 2

 

Yep thats where its leaking. I'll go with the 2 then as thats all thats readily avaliable. Why are there the differences?

 

Clean it up good with a wire brush at the leaky joint, heat it up hot with a propane torch and touch some solder to it. Worked perfectly when I modified mine for my TVS. Guaranteed to work.

 

Good call, i'll try that guess it couldn't hurt.

 

Good call. I was thinking the same thing. The piping is so soft some plumbing solder should seal it right up.
