Deleting heater hose

I got rid of my heater and need to know if you can block both hoses off at the water pump and manafold or do you have to have the one feeding from water pump to the manifold that how I have it now just to be safe but looks ugly with hose from pump to manifold it's a street machine hope you can just plug em

As far I know you can block them off with no ill effects. The one from the water pump is just pushing water to the heater core and the intake hose just is a return back to the engine. I see no reason not to block them off if you are no longer using the heater core. The way you have it now is how we used to bypass the heater core when It leaked or if one of the heater hoses blew while on the road.

Thanks I didn't know if the manifold used water or if its a dry manifold and like you said if it just returns back to the block then I can plug them both

Yes you can plug them I have them plugged on mine the intake gets it water from the thermostat when it opens and the bypass on the thermostat housing beside the top rad hose

Thanks guys Appreciate the info this site is the best at Knowledgeable BBF guys that get right back no matter how small your Problem is

Ignore.

Edit because this post is wrong you can't block off water pump and intake ???

Was gonna say that, but then got a bit confused. You can block both ends of heater hoses. You cant block the hose between manifold and pump unless you use a thermostat with bypass holez in it. Otherwise you wil dead head the pump. I was gonna say this in my edited ignore post but then thought you just wanted to do the heater.

Ok thanks for looking out

Forgot to mention if you want to plug your manifold to pump hose, you can make your thermostat into a bypass one just by drilling a few holes in it or as you are not running a heater you could just leave it out, or take the centre out so as you still have a restriction. There still seems to be a bit of debate as to whether you need to restrict the flow in the water system and as to whether leaving a thermostat out can increase engine wear by delaying the time the engine takes to reach optimum operating temperature. Therefore if you decide to block it I would go with the bypass option these are available from the likes of summit, jegs etc, or like I say just drill your own.
I cant remember the stock configuration of the pump to manifold hose, but on mine I just have a very short piece of silicone hose between the pump and manifold, I seem to remember I installed at the same time as the pump it was a little fiddly and you need to remember to put both hose clamps on the hose before you fit the pump. I think it looks quite neat and it negates the need for any bypass etc.
As for the other hose that goes from pump to heater to manifold this will be fine just plugged in fact I read somewhere it is better to plug it than to loop it out.
Hope this helps

So lets make sure I have what you are saying besides plugging the heater hoses supply and return your saying I can get rid of that pain in the but 2 1/2 long hose from the manifold to the pump by drilling some holes on the out side edge of the Thermostat or they sell one already drilled from summit or jegs if I am understanding you right what size hole and how many to drill in Thermostat and this won't give me any over heating Problems

Hey I just looked on summit can someone check this part # EMP301 and if it is for Eliminating the short hose from water pump to intake manifold thank would like to get rid of that one to if I can

Don't now if Mentioned it but this a street machine and its a 429SCJ that was a virgin in 1984 when I built it and it has less than 10K miles on it. This is my baby and I don't want any over heating problems its in a 79 F-150 but has a F350 Radiator and was also think of putting an oil cooler on it I've read that with boarder line Pinging witch I had no problem in the 80s with 93 octane and its still Does okay I buy 93 no Ethanol gas and mix in some 110 octane because my CR is 11.5 to 1 and bored .30 over just want to have my temps the best I can and from all the dyno sheets I've seen on here the oil temps were 130 to 175 degrees and I've read oil and water temps should be the same

That will be fine. Its what you do when running an electric water pump. As to octane and oil coolers you should maybe put that in another thread with another title. All I know is you need to run the pipes to the cooler as large as Possible
