Waterpump: Heater Supply Outlet Block off?

I have this type of a water pump on my 1969 351W.



Is there a part or something that I can use to block off the Heater Hose Supply Outlet on the far left side (facing the water pump)? Is this thing pressed in or does it screw in? I was thinking about using a freeze plug if I could find something the same diameter, but would rather just block it off temporarily.

It is in a 54 Ford Customline with no heater. I do plan on putting in a Vintage A/C unit, so eventually I will need to hook up the heater, but until then what can I do to keep the water in the system?

I tapped mine for pipe thread, and then used a standard brass block-off fitting

Re: Waterpump: Heater Supply Outlet Block off?

It is a water inlet, not a water pressure outlet. Water flows into the pump from those two connections.

You should close loop from the water outlet ( to heater core) on top of your intake manifold, to that lower water inlet on the pump.

I would really hate to go into this again, and I will not be dragged into another fight about this..... but you should not starve the water pump for water, by plugging it off. May cause overheating of your block from lack of waterflow, when the thermostat is in the closed position.

Or you can listen to counter arguments, and possible risk damage to your motor.

desertdroog...........
You can just buy some rubber caps the go over the water heater supply nipples at any parts store... You need to cap both of them as they are both open to the inside of the water pump... one is out to the heater and the other is the return from the heater...

NO Mike.... Those two nipples don't flow water into the pump.. .. Well one does but it just the return from the heater core.. and the other one supplies the water to the heater core..

It shouldn't cause any over heating issues unless the raidator is insuffent.. or pluged.. or the fan isn't working properly..

Re: Waterpump: Heater Supply Outlet Block off?



The tube you want to delete is the heater return hose. Look at the Ill. PN 8A500 is what FORD used on Heater Delete in the old days as has been mentioned. I would do what the other poster suggested and remove the tube (pressed in) and pipe thread it to accept on of those pretty anodized aluminum hex plugs. You can then insert a threaded inlet tube once you need the heater.

The tube above this one (WP bypass) is the one that cannot be blocked off.

Thanks for the idea. Where on my manifold would I connect that water outlet to? I have the one closest to the center going to the manifold already. I have the one on the outside open with no where to go. Some images would help me figure this out. I am using a 351W mainfold off of a junkyard Bronco as the longblock I got did not have much to start the rebuild.

I am not trying to argue one way or another, I just need clarification about what you are talking about as I am not totally familiar with the SBF in this capacity. Hence, coming here for questions.

That diagram which shows Ford PN's for the block off is interesting. Where could I get those if I decide to go that route. I don't have access to dies and taps to get a brass plug in there and unfortuneately, the waterpump is on my car with a new radiator, etc.. as I did this last night only to find I had an open outlet with no where to go.

Re: Waterpump: Heater Supply Outlet Block off?

I did the rubber cap on my stock water pump before I got an edelbrock water pump.(threaded from factory) You can usually get the rubber caps in the "self help" isle of your local auto parts. Be carefull with the rubber caps, mine broke once then a new one lasted 3 years before i changed the pump.

Re: Waterpump: Heater Supply Outlet Block off?

By the way the waterpump I have is exactly the one in the first image I posted. The way my radiator was set up required me to use Ford Motorsports Water pump with a drivers side outlet.

I don't know if that is the wrong one for my app or not, but I trust that Ford Racing sold me the correct part for my engine.

That is what someone else told me, to always check that rubber cap if I go that route. Due to the heat in Phoenix, Az he says that will be the first part to fail on my cooling system, as long as I don't overpressureize the radiator with a cap that is too heavy (16 lb on a 7 lb radiator). A headache I don't want to live with if there are better options.

So Edelbrock sells a waterpump with that outlet threaded? I may have to look into that for a long term solution.

I am still interested in learning about closing the loop as Mike66 recommended.

Re: Waterpump: Heater Supply Outlet Block off?

Don't use the caps if you can at all help it. They do NOT last very long and will fail when you least need it, of course. Pull the nipple and plug the hole with a brass threaded plug or at least a brass freeze plug. If you are plugging off heater connections, they have zip to do with water flow in the engine.

Yes I have the 8841 water pump, it came with threaded nipple for the heater hose, i just took it out and put in a plug.

Re: Waterpump: Heater Supply Outlet Block off?

The only outlets on a centriugal pump are those that come from the outside of the vanes. Any passage that goes to the center portion is an inlet. I don't know whether you can starve the pump or not by blocking off those two ports but I do know that the rubber caps fail. Just use a short piece of hose from the engine to the inlet ports and forget about it. the hose you use will last 10 times as long as those caps. If you are going to need them later for the A/C then it does no harm to make a simple loop to keep them from getting rusted and full of crud.

Re: Waterpump: Heater Supply Outlet Block off?

Of the two inlets on the passenger side of the water pump. I have the topmost one going to my manifold. So I cannot loop the inlets together without addressing the manifold. Is there another water inlet/outlet on my manifold that I can put the bottommost inlet connection to?

Here is how my car is set up.


If you look at the thermo housing inlet, there is a smaller inlet that I connected to the topmost waterpump inlet. The one to the left of that on the water pump is where I don't know how to loop it into my manifold.

I figured this would help since my terminology isn't the best. I am learning guys, thanks thus far!

Re: Waterpump: Heater Supply Outlet Block off?

You have a plug in the top of the thermostat housing that is normally used for a temp sender, you could use it. If you have put in a temp sender then just to the rear of the distributor, on the driver's side is another plug that goes to the water cross-over. You can put a fitting in it to connect to the other pump connection. That way when it comes time to install your heater you will have all the stuff to do it with.

Re: Waterpump: Heater Supply Outlet Block off?

HHHMMM
I was under the impression that both nipples went to the heater core???
"SORRY MIKES66"
......but then in the exploied view it shows only one cap on the lower nipple?? did the other one go back to the block or manifold instade of the heater core??
