AC to Non-AC Heater Hoses

[73TopBanana]

ok thanks

[Shoooter]

I'm almost done my AC car. Right now I don't have any underhood ac parts installed other than the heater lines and fan  Are you saying I won't have heat? I can turn my blower motor on and off.

@Shoooter Do you have an AC heater box? If yes and you don't have some kind of temperature control valve then you will have heat all of the time and no way to shut it off.  If you have an AC heater box and a temperature control valve, you can have heat when you want it and no heat when you want it.

 I have the AC box but no temperature control valve. Where can these be purchased? 

[headejm]

Not sure how original you are trying to keep your underhood area. I went with a factory looking valve that worked with the factory fender bracket (see photo above). I bought it on Ebay but the history of the order is gone.

Another option is a company called 4 Seasons. They sell different kinds of valves on Amazon, Ebay, Summit, Rock Auto, etc. Here is a valve that should work but you have several options. You probably want a cable operated valve like the original (and you can use the cable that goes to your dash lever).

Is that four seasons style correct for a 71 Cuda?  Does anyone have a number for a factory style one? 

Also could you post a picture of what the factory style looks like?

Thanks

1970 factory-looking style valve.

[Shoooter]

Thanks for the pictures. Both adds say 70 to 74 e body is your style for the 70 and the other style for a 71 and up? Do the 71and up have the mounting plate attached or is that separate like the 70?

[Shoooter]

I found a old thread. The 71 is the silver one. I just ordered it up. Thanks again for all the help.

Hi Skidmark, would you happen to have any photos of this bypass method in place?
Not sure where to install it.
Thanks

[Shoooter]

If you are eliminate heater core wouldn't it just jump from the intake to the water pump depending on motor size?

[Skdmark]

Remove the two short length heater hoses that go from the heater control valve to the firewall/heatercore. Pictures 1-2
Put a pair of rubber caps on the heater core nipples sticking out from the firewall (you might want to siphon out the coolant trapped in the heater core).
On the backside of the heater control valve install the bypass hose with a pair of hose clamps. Picture 3

I picked up my bypass hose and rubber caps from my local auto parts store (Advanced, Autozone etc.)

Should take about 5 minutes.

Pics below. The image with the bypass hose shows it laying on top of where it should be installed.

Hi Sdkmark, nothing like photos, this is want i was looking for. Just curious, what happens if i do not siphon out the core?
Thanks

Nothing really, other than having coolant sitting in the heater core not being moved around the cooling system. Worst case your heater core develops a leak and you get a wet passenger side foot well.

I used the bypass setup temporarily so I could still use the car while I was having my heater core rebuilt by Glen-ray. Once I got my heater core back I reconnected the heater lines.
