All about heaters.

Thanks!

I am also interested in this - also is there a trick getting the cables off at the heater? Mine seems to not want to come off easily

[red450ih]

Has no one else had trouble installing new reproduction cables due to poor fit (quality)?

OK you heater experts, hopefully one of you can help my poor old brain out. I have 64 with deluxe heater. Finally getting things hooked up, but what I am wondering is what does each slider do.

Is up the neutral position?

I would assume that the heat one is temperature and the down position is a hotter heat, correct?

What does the center one do beside turn the fan on. There is a cable, but for the life of me can't figure what function it is doing?

The def slider, if that to change from defrost (down) to heat (up)?

Sorry if it sounds like stupid questions, but I haven't found any explanation anywhere and use to controls with different labeling.

Oh the only clear picture I had was one before I replaced all the arms.

Thanks all

Palf70step all the way to the top on all three is the neutral or off position. Left side is defrost when it's all the way down it closes the baffle so all the air goes to the windshield to defrost, all the way up and the baffle lets all the air go to warm the feet. Right side adjusts the temp up and down the top is off, down is hot. The center control is the fan speed at top is off down a bit is low then medium then high all the way down. The workshop manual might have some info on the heaters I can't say for sure cause my knowledge comes from working on GM stuff for years it's been the same for a long time I believe. Hope that helps any....Vernski

I'll take experience over books most of the time. Thanks for the input Vernski. I just got the defroster tubes on imne hooked up right, so maybe I can tell the difference when I move the controls.

I have a 64 C10 with the thrift heater (one knob). I'm trying to take the core out to check it and I undid 4 screws that hold it in place. Each time I hear something drop like a nut or clip to thread into. I can't get the top off since there seem to be 3 screws on the back side that I can't get to without taking the entire until out. Do I need to take the glove box out to get to the bolts that hold the unit in?

[Captainfab]

You will need to take the entire heater unit off of the firewall. There are 2 studs that have nuts on them on the inside of the firewall. Then once you have the heater unit removed, you can separate the top and bottom halves apart. Then you can access the heater core and the brackets that attach it to the top.

[akqj9]

Thanks. I hope the guy who designed that is rotting in hell. It should be designed so the core can be replaced without removing the entire unit.

Thay are all a pain. I am doing a 1961 impala.

[argonaut]

Trust me, taking the hater unit off a 60-66 is 10 times easier than a 67-72 where you also have to remove a hood hinge and the inner fender just to get the damn housing off the firewall.

I installed a new core but the fan still blows cold air. My engine doesn't get any hotter than 180. Is that enough to have heat?

[Captainfab]

That is the '60-'63 deluxe heater with a '64-'66 heater core. It sounds like you are wanting the recirculating heater. Also known as an economy heater. Everything is inside the cab. It does not heat as well as the deluxe heater which may or may not be an issue for you. In cold climates such as here in Idaho, it is an issue. There in Portland you have mainly a lot of moisture to deal with.

[Captainfab]

Yes 180* is enough for you to have heat in the cab. It sounds like you have either a flap open that shouldn't be or one closed that should be open.

Is there any way to pull the “blend” flap on the thrift heater to maybe replace the rubber gasket around it? I can’t really tell if the rod that goes thru the flap is spot welded or just a wedge fit....not too big of a deal, but sealing it off a little better since it’s always “on” would be nice.

[Jferrante]

What am I missing here? I rebuilt a thrift air heater box last year with this same heater core without issues. Now this time the heater core brackets are too big? Were there 2 size heater brackets based on heater cores? I am just going to cut these down to size to make them work if thats the case.

[rvrfoot]

That looks a little thin.

Agreed - I am going to send it back and get the thicker core one.

[rvrfoot]

Show pictures when you get the other one.

[Captainfab]

It looks to me like the core may be the correct thickness but the tanks are not the correct size.

[Jferrante]

Here is the update from before - the new core came in today.
The thicker core fits the brackets

[botoepfer]

great thread I have the cheap heater in Our 63 and it appears the controls are Home made?

[Powerlineman06]

Anybody knows where to buy the control valve like the one on post #81. It is the control valve inside the blower box which is controlled by a cable on a 1960 c10 heater.

[jbgroby]

You can find some on ebay.

or this company has rebuilt units.

Need some help. Took me awhile to find a thread that talked about heaters. Yes, these 60-66 heaters can be a challenge.

I have a 1961 C30 Apache Stakebed. I need to replace the Heater Blower Resistor. This truck has the recirculating heater. On this particular year, it appears that the resistor snaps into position on the backside of the heater box. Its difficult to get your hand behind the heater box to replace it.

Two questions:
1. Where can I get a resistor for this truck?
2. Any pictures for a breakdown on how to remove the heater box to replace?

I've attached a photo on how it looks. It was like this when I bought the truck. Only thing I can figure is someone took it out and couldn't get it back in.
