LS1 Steam vent hose routing
Hey guys,
I am looking for ideas on alternate ways to route the LS1 steam vent hose from the heads. Currently I have a largish header tank and the hose vents into this tank. I am looking to replace the header tank with an inline filler (simple and neat in appearance) and looking for options for the steam vent hose routing. I have seen many options such as tapping into the water pump, tapping into the radiator (long distance in a cobra), into the top radiator hose, etc. What I have not seen is it being plumbed back to the heater hose outlet. Whilst this could be an option it would be neater to go to the in-line filler neck. I was thinking to tap into the inline filler at the highest point below the radiator cap. Or getting a filler cap made with a longer neck so there is room for this. Anyway, I am wondering what other LS engine users have done, any pics would be great. Cheers. |
I originally had the steam vent running to the header tank as well. I wanted to tidy things up and with the change of manifold I was able to mod my water pump to put a filler neck on top. This let me delete the header tank and I ran the steam vent to a point high on the filler neck.
I now just have an overflow tank in case of a boil over. Don't want to be dumping coolant onto the track surface, tyres etc. Ideally you want that steam vent going to somewhere as high up as possible to burp the air out of the cooling system. If you run an inline filler in the top hose just tap it into the side of it would probably be good enough. http://www.clubcobra.com/photopost/d...iller_cap2.jpg Cheers |
Mike, I Appreciate the pic and I had not thought or seen of a filler modified to the water pump but I like it.
I have a overflow connected to the headertank which I was to continue using from the in-line. Is the filler neck in the pump drilled and welded on or has this been tapped in. It looks welded but I cant see. Cheers. |
Drilled and welded. However I'm going to have to cut it off and re weld it as I've got a pin hole in the weld that I can't seem to get rid of. It only weeps a little but it annoys me.

Perfect , Thanks mate. This has given me ideas for a different layout for hoses, pipes etc.
