I need a one, as i broke mine.. does any one have one handy? This is the black thing under the hood with 3 hose going to it..Thanks Jeff 713-298-2078

 

Not to be an ***-hat, but this is a readily available part (O'Reillys, etc.)
and to the best of my recollection a Jackson ought to cover it.

 

Parts stores carry them and they aren't that expensive. That's one part that you would rather have brand new.......

 

I bought one today 18.00 new from the auto parts store, I'm not sure.. why i thought these were obsalete? Thanks, Jeff

 

What exactly does the "heater control valve" do anyway?

I don't think my car came with one.

 

I belive. under vacume, It opens a valve that alows hot coolent to flow to the heater core. my spelling sucks today

 

OK, that's what I thought also, just wasn't sure.

My '82 never had one.

 

how did yours do it? i would be interrested in getting rid of mine and going to a non valve system.

The water always flows through the heater core. As long as the temp control is not set to "heat" the air doesn't flow over the heater core and does not get hot.

Well, it might heat up a little...but it isn't much.

 

My 85 never had one. Some say that the water always running through the heater core is better in the long run as it never has a chance to sit up and rust due to non-use,which down here is about 90% of the time.

 

decided to do it when i pull the heads and redo the intakes and exhaust. im tired of all that rubber hose - and i have air so it does not actually get hot there.
i just want to clean things up and not have to deal with that 3 way valve.
i can always turn the heater off with a valve during summer if i want, but probably not.
