the waterpump sits higher than the coolant bleed pipe under the intake manifold and coolant bleeds best at the highest point. i would like to remove the coolant bleed pipe for a cleaner setup and install plugs by wegner in all 4 holes

could i tap the top flat part of the waterpump and run a hose from the waterpump to the radiator?

 

I'm sure you could do it...you can do anything. HOw effective it would be, that is the question. The purpose of the coolant pipe is to keep air pockets from gathering in the heads, forming hot spots. Those hot spots could cause problems (elevated op temps) and maybe detonation. I could be wrong, but just my thoughts on the subject.

 

well i tried doing a search on this and couldnt find what i was looking for. i seen this in a thread a long time ago and cant find it. i read up that the waterpump sits higher so wouldnt it bleed air better than the coolant bleed pipe? wouldnt it also prevent hot spots if its higher?

 

Looking at pictures I don't think the waterpump is actually higher. I may be wrong. If it is, its only like 1/4" higher, not high enough that it will make a difference. At first I thought you were referring to this post in the FAQ. https://ls1tech.com/forums/showpost....5&postcount=49.

The LS1 has natural steam passages to route hot steam back to the radiator, hence the steam lines. same thing on LT1s, except theirs is on the back of the head. Why not use what the factory gave you? It worked damn near perfect for my swap.

 

similar to that post but instead of running that hose to the bleed pipe, running it to the barb on the radiator and installing plugs in all 4 bleedpipe holes

 

I've heard of people doing that, i just can't think of any off hand that have done it. I don't think that would be any different than running a hose from the steam pipe to the radiator, or 2 inches away from the top of the water pump. Not knocking your idea by any means, just don't get it. Maybe someone else will chime in and be of more help.

 

just curious on the setup i had in mind to clean things up a lil. GM system does work good damn good tho

 

so people have tried the idea i had in mind? i cant find that post so i need word of mouth for security

 

They didn't tap the water pump, just replaced the steam pipe with block-offs like on the rear of the heads.

 

has anyone tried the setup im talking bout....or heard of it?

 

is the factory steam tube more effective than eliminating the tube and blocking the holes and drilling the waterpump and running a hose from the waterpump to the radiator?

 

I'm sure the steam tube would be more effective. There are no steam passages in the water pump. I say go for it if you think it will work.

 

While I am interested in seeing how this works out I certainly wont be the one to try it first. You can barley see the cross over pipe on my set up so it not a big deal to me anyway, but I would be a little concerned about hot spots in the heads with that blocked off, but I am certainly no expert on this kind of thing

 

haha ya im not gonna try it either unless i see it done or hear positive word of mouth
