Water pump / steam line mod
Has anyone done the mod and has pictures or info on it. Im looking for any links on here but cant find anything that really explains it. If you can help me out that would be appricated. Thanks

Re: Water pump / steam line mod
You drill and tap a barbed fitting to the flat spot over the upper port. Nothing special about it
Be careful because the alum is very thin there and easy to strip. A 90* fits best
Alternatively if you have the stock 3rd gen radiator, check the heater core return port to see if its threaded. If it is, screw a barbed fitting directly in there and run the steam line to it. Saves you the trouble of permanently altering your pump

Re: Water pump / steam line mod
The part I posted is the actual part I ordered and used on my Holley fuel pump. It's a 3/8" NPT to 3/8" barb but you can find them in any combo. Remember to use the correct NPT tap and a little Teflon tape.
The key is to tap the hole progressively larger and test fitting your fitting so that it seals at the angle you want it to. Meaning so that the barb is pointing in the direction you want it to while still sealing properly.

Re: Water pump / steam line mod
Do you have a port just under the overflow port? If you do mine came plugged when I bought it last year. Its a rubber cap with a hose clamp on it. If you need to plug it just use a piece of hose and a bolt in one end with a couple hose clamps.
heres a pic of mine with the 3rd gen rad. Only pic I got at the moment
Heres a pic of the waterpump on the car just got to get a longer hose to connect them

Re: Water pump / steam line mod
what i did for mine was put a short piece of rubber hose on the port on the rad and put a brass fitting in it with a nipple on it and some clamps and ran my steam line to it. i can get pics if you want.

Re: Water pump / steam line mod
Here's my idea for it.
I found a tee at the auto parts store that should work nicely. I used a short rubber nipple between it and the radiator, run the steam line to the smaller side and will cap off the other side of the tee. It probably won't look all that great, but should do the job nicely.

Re: Water pump / steam line mod
It will do the job yes and as long as you dont mind the ways it looks who cares. I did mine with the water pump MOD as I cant stand having lines, tubes, wiring ETC going all over the place. It drives me nuts and in my mind makes my motor look cheap. Thats just me and maybe im too **** for my own good

Even with clamps? I'll have to check, but I thought it was a heater hose tee for... "the F word". Um, a Ford product

Re: Water pump / steam line mod
that looks like its a pretty solid solution if you dont want to drill the pump for sure.

Re: Water pump / steam line mod
The vacuum cap where I put the arrow will blow right off its not going to work. You can either put a bolt into another piece of hose with clamps or get an elbow etc but that little cap will not work

Re: Water pump / steam line mod
Oh. Yeah, I just put that cap on there to keep the debris out. I'll put a hose type cap on it when I get it in the car. Thanks for keeping an eye on me though

Re: Water pump / steam line mod
Ok, here is what I came in the mail from Summit
Autometer radiator hose adapter part #2282 ($50 shipped)
I had to go buy a 3/8 to 1/4 npt adapter, then a 90 to get what you see here. ($15 at Ace Hardware)
then found a suitable place that didn't interfere with my CAI and cut the hose there. I am using the stock 4th gen upper hose. Cut out about 1/2" to get it perfect.
now surprisingly this made filling up motor with coolant very easy. I disconnected the adapter, and just pivoted the upper hose thats still attached to the waterpump straight up, and filled the block. The air came up the steam tube, and once coolant started running out of the adapter, I stopped and connected everything. Added a little more to the radiator and I was done....

Re: Water pump / steam line mod
I still had to add some coolant after I fired up the motor..... had to burp the heater core too..... still, a lot easier than the last time I replaced the water pump two years ago or so....
the adapter is above the TB, and it is upstream from the motor too. I am really happy with this so far and it seems to fit a lot better than the ls1 radiator I was using. Just a cleaner look for me.......

Re: Water pump / steam line mod
Hey guys, I am looking at my steam tube options, does drilling and putting a fitting on the water pump actually work? I would think that is creates a mixing flow in the coolant...no?
#41
Re: Water pump / steam line mod
I wouldnt recommend it. Its a steam line to relieve hot spots from the 4 corners of the cyl heads and greatly aids in bleeding the coolant system. It does show some promise in the design
Id grab two of them for a 4 corner setup, then cut and tee the crossover lines. Port it to the WP like shown or radiator

This is the best solution, IMO.
Wish I would have know about it before doing my swaps. It's what I'm going to be using in the LS swap in the '57.

I know this is old, but did you still drill and tap your water pump? I like the set up you went with, I just dont want to have to drill into my waterpump if I can avoid it.

Re: Water pump / steam line mod
Nope, I did not drill my waterpump
I specifically wanted to avoid that route just in case I am out of town with the car and the waterpump craps out on me........ I usually carry enough tools to change a waterpump, but not to drill and tap one.... lol

Re: Water pump / steam line mod
I tapped the bottom of the water outlet by the thermostat, that way the steam is pulled into the radiator and if I need to change the pump, I can do it without having to modify it. Don't need to change the outlet too often. I bent a nice piece of 1/4" stainless tube to go under the TB then down along the WP then down and around the outlet, but behind the nipples for the heater. If you weren't looking for it, you would never know it is there. I wanted to keep from putting another hose/tube to the radiator
