Heater Tube Delete - Plumbing

[RotFox90]

Hey Guys,

I know I’m not the first to do this so I want to see how everyone did it to give me some ideas lol.

I installed an elbow where the heater tube was plumbed into the lower intake and figured I’d get a piece of heater hose right to the water pump and that would be it, but I forgot about the alternator bracket & that’s in the way of the hose. Get a taller nipple between the fitting and intake? Modify alternator bracket? Do I just plug it off?

I’ll post a picture shortly.

If the car is injected you need to find a spot for the ECT sensor and make sure that it is not in a dead spot. My understanding it you need to install the ECT when the heater tube assembly installed on the lower intake and get the sensor portion into moving water. The nipple on the water pump can simply be capped with a plug and hose clamp.

I bought a thermostat housing with a threaded hole for the coolant temperature sensor.

Capping off that nipple on the waterpump won’t hinder any coolant circulation through the engine?

It that I’m aware of. To my knowledge it’s only for flow through the heater core. My buddy has it this way on his 69 fastback and zero cooling issues.

I opted for that route. Let’s give it a shot!

I’ve been running mine the way you plan to for several years. Works good for me.

Very cool, which way? The way I stated in the first post or in the picture posted by AeroCoupe and then my picture?

Awesome. That’s always reassuring to see someone else has had it that way with no issues lol thanks.

But will you still have heat?

Do you have heat though? The other spot on the heater core that the hose ran from to the coolant temp sensor part of the tube does that still need to function when you get rid of the heater tube? It seems like coolant is circulating thru the other side of the tube which goes into the lower intake.

The thread it titled "heater tube delete"... He does not have heat

Cap the pump and pipe plug the intake, that flow path is specifically for the heater core

And just saw this is an old thread

Yeah I've been doing so much research sometimes when I reply to something I forget what the title is lol. So I definitely want heat and from what you just describe it doesn't sound like I will have heat?

Yeah I always look and see when the when the person was last seen so I always usually check that. But my thing is just because they weren't not seeing for how many every year it doesn't mean they will not get a notification and reply to something that will help someone LOL

And by the way to fill you in on what I'm doing I'm adding a vortex V3 to my '94 and yeah I definitely want heat. The ECT sensor needs to be relocated because of the alternator being moved and so some people have put the ECT and the location where the tube actually screws into and so in doing that of course now I'm trying to see what people have done for still having heat and still having a functional circulation of the heater core to the intake. My research today has given me some pretty good or a pretty good idea of what to do and which route to take but like I said I like to try and find folks who have done it first hand
