How are you guys routing the return line to the radiator? I understand that the collection block is the high point but, wouldn't going "down hill" back the radiator pose a problem? Any advice, opinions, tips or pictures would be greatly appreciated!

There's another thread on this with heaps of pictures, can't find it though.

Here's mine. I've added a T-piece to the left there where there's a gap which runs through to a free port on my radiator low-pressure side.

If you have ever seen how much coolant/ pressure comes out of those steam ports you will realize that it doesn't matter that the block is the highest point.


Although in mine my rad was lowered so I have an expansion tank mounted to the passager side head and it is level with my block for the water vapor kit

I have the single return line at a slight upward angle to promote flow back to the radiator. Hard to say if its working 100% efficiently like that, but its better than not having the rear of the heads vented at all.

I was wondering this as well. I have to get creative to put that thing somewhere it looks nice.

Is that a surge tank with a fill cap next to the TB? I'm in the process of building one so i can lay my radiator horizontal. Can you offer any tips? Any discoveries?

I plan on venting my steam port and radiator line (for purging air) into the surge tank.

Yes that is my Fill point for the hole system. IT it very easy to fill my system and get all the air out set up like this. The bottum port on the surge tank goes to the top of the rad and the port on the side goes to the water vapor system. I did it like this as I dropped my rad down about 2 inches and pushed it forward.

Im not using the Kurt Urban block assembly but...

I just T'd into the right front port and ran the return hose to the radiator from the T...

My problem is finding a return location. I do not have a port in the radiator for mine. I guess I could pay someone to weld it in (can't do aluminum with my tig). Should not be terribly expensive.

I have seen how much water actually comes through those vents. Your setup will work fine.

Get one of these and tee it into your upper radiator hose.

Is anyone using something like this?

I was thinking about just having a -4 AN bung welded into the radiator right below the cap. Would that work?

Mine returns right to the top of the water pump.

that Jegs fitting seems like the easiest way to go. Now if someone will just do the measuring for me so I know which one to grab. That is the route I will be taking. I would like to use a ssb line tho rather than a piece of hose.

The best is if you could keep it going uphill, that is possible in about 1 in 20 cars! Most in the pictures seem decent. The most important part is going up from the head to the collection block, then having that 5th port highest. Once the air collects in the block and gets into the single line even an electric water pump can push the air down if needed. Post two shows line installed on the head then going down, this is bad as air will trap in the high part of the single line if flow volume is low.

So what is the solution for feeding the line out of the 5th port back to the radiator? Rout into an expansion tank or something first?

SirNemesis

Thanks for that Kurt. I asked that question on YB and people there assured me that it'd be OK. I'll change the lines around a bit.
