Am I missing something on my heater assembly?

[tincan1966]

Does anyone have a picture or diagram from an assembly manual?

[65chevysub]

Sorry to break in on this thread, but can I change from a Thrift-Air heater to the deluxe setup on my '65 Suburban, and how hard would it be to do this?

[1963c-10]

Not hard as long as you have all the parts. The conversion will take an hour or two. I did the opposite conversion a few months ago. Went from a deluxe to the standard heater to make room for a big block. You will have to get the extra levers for the dash or just get a deluxe control panel, everything from the diverter box to the dash is the same, pretty much the extra cables and deluxe heater control box is what will be needed. You will not need the two delete plates....and will have to remove a piece of insulation for the deluxe heater to pass through the firewall.

Thanks 1963 C-10. I'll look for a lever set and start working on it.

[1963c-10]

If you look under the thread "all about heaters", there are some factory diagrams to help out. I believe they are the 60-63 cab, but the conversion is almost identical.

I have my truck in thousands of pieces right now so I got the heater assembly out and took a few pics. This is a completely stock, unmolested original with nothing missing. The hole is just a diverter for the air. There is a baffle in there just like the one for the floor/defrost baffle. One of the cables from the panel controls it. Pics are with is open and closed. I hope this helps. Anything else I can get you pics for, just ask.

[rideblue00]

I agree with pdxhall. My 66 C20 is also unmolested as well. And it looks like pdxhall's pics.

[jbgroby]

Ok Do either of you have a pressed board with a hearter relay still on your units?

[rideblue00]

Yea. Ive got 3 of the heater units and they all have that.

[pdxhall]

Yeah, my relay is still on mine also.

This is in the 1964 section of the Assembly Manual. It shows (4) Deflector, p/n 3843950, for RPO C42 (Deluxe Heater). There are no other pictures of it. So apparently there WAS a part. Whether it was later cancelled or easily fell out, who knows? I appears to be plastic. Anybody got one of these?

[BLK65K10]

victoriahardware thanks for posting that. I have had over 40 trucks most with deluxe heaters and I don't believe I have one of those but I will be on the lookout for one and share if I come across one.

[65 C20]

Well it looks like I may have the only deluxe heater with the original deflector.
I just looked at mine and it is still there.
It is made of plastic and it has 2 ears on it that are a friction fit in the slot on the left. One ear up and the other down. After that it slightly angles out from the side of metal box.
It is covered on the top and front, with the bottom and right side open.
Deflects heat down to passenger feet. It is a rather loose fit and I can see why most are missing. Acidently hit it with your foot and break off one of those plastic ears your done. I don't see why it couldn't be made up of thin sheet metal and a screw.
I know, I know you all want pictures.
I am not that good on this computer and will try to post something later.
Cal.

[65 C20]

Well now lets see if this works.
This is the elusive plastic deflector for the deluxe heater.
This is what it looks like installed.
I have more of it out, will add to next post.
Cal.

[65 C20]

Sorry it took so long, but this is my first try at adding pictures.
I have been watching this forum for some time now and am glad that I can contrbute something. I have learned a lot and now my turn to share.
In the pictures there is a gray swirl in the black plastic that I thought was a scratch or stress mark but it goes thru to the other side so part of the mould process. You can see those 2 small tabs that would be easy to accidently hit with your foot and break off.
Not sure if this could be made with one of those new 3-D printers.
If I was going to replicate this I would use thin sheet metal.
I would have a tab that goes in under the hole on the left slot on heater box, over the existing metal that is in between the two holes.
I checked and the angle that it flares out is 45 degrees.
The part that would be bent over for the top I would leave an extra 3/8 by 3/8 tab that could be bent up to go inside the right hole right side top.
The deflector is open on the bottom and right side so could get a screwdriver in there to bend it up to hold it in place.
Hope this all makes sense. I am going to try making one up myself and will post a template of it later.
I was surprised that of all the people that posted to this thread could not come up with an original.
I wonder if any of those Lambert trucks had any.
On another note I have noticed while looking at varios engine bays on this forum that a lot of people are missing the heater core outlet support brackets. I have recently purchased 2 from a member in this thread.
Hope this makes sense and can help out some members.
Certainly looks better that a piece of duct tape.
Cal.

[BLK65K10]

Very nice. Thanks for sharing. I will be searching for one. On a side note how is it you have one of those and need all these other heater parts from me!! LOL!

[Sharps40]

I gotta look again...I am pretty sure I have 2....a 64 and 65 W/o the hole.

[hemifalcon]

Wow... Finally--the hole can be filled.. Just a small deflector--guessing those little pieces of plastic dried up when the heat was in use--or in hot weather and just turned to dust.. I think I'll probably make a small deflector as well--I wonder how much of a difference the little thing makes in getting heat to your feet!

Glad I could help.
When you make one up post a couple of pictures of it before and after it is installed.
I have a couple of ideas as how to do it but want to see how your idea looks like.
I'm sure there is not a lot of heat deflection for pass. feet but with out it you could be robbing air not going up to the windshield defrosters.
I realise that for some of the members in their climate it would be just for looks but up here it is nice to have a funtional heater system.
Cal.

[Sharps40]

Double checked....neither my 64 or 65 have that hole. Intead each has a 1/4 x 2ish inch opening in the bottom of the duct to blow a touch of air on the passnegers feet.

[BLK65K10]

Thanks to 65C20 I knew what I was looking for and I found one in my stash. It has a broken leg but I also found one that was broken off but the two retainer legs were still there. So I can make one out of two. Always check the glovebox as you never know what you might find in there.

That deflector part # 3843950-grp.# 9.783 is in the original price guide (.06) dealer price !!! But it isn't in the original parts book from 1964.
(I'm telling my age) I worked at a chevy dealership as a young kid in the parts department and I remember those little plastic baffles that people would come back after a few weeks and raise hell about them breaking or falling off and us having to keep track of all the customers wanting replacements. So finally the service manager had the new car get ready guys to just remove the baffles to stop the madness !!! These were on the deluxe heater units.
I wish I would have collected up and saved all those baffles.
