As I recall the only seal is part H and it goes between the fan case and the evaporator case on the firewall.

Re: Need a diagram/exploded view over the AC STV valve for a 1963-66 factrory AC Corv

Ok Hary i see. So there is only a seal between the blower motor and blower motor fan case. No seal between the blower motor fan case and outer AC box
Have a look at the insulation on the evaporator housings in the pictures(the pictures are not of the AC boxes on my car but a helpful friends car)
All of the inside is insulated and i wonder if i should copy that. The insulation on the outer AC boxes looks really good to me
I have a insulation kit(DocRebuild)for the outer AC box but it is not so many parts as seen in the pictures but that can be easy made

I am going to have the new AC heather core soldered around the pipes and pressure tested. Should i pressure test my new evaporator as well? It is brand new and made in the US

Re: Need a diagram/exploded view over the AC STV valve for a 1963-66 factrory AC Corv

Claus, that is not what I was trying to say. I believe the seal is between the blower motor fan case and the outer AC box. No seal between between the blower motor and blower motor fan case.

I will continue to look at this just to make sure.

Re: Need a diagram/exploded view over the AC STV valve for a 1963-66 factrory AC Corv

Thanks Harry that makes sence because when i tried the seal on the blower motor and blower motor fan case it really did not fit
Thanks to Harry i know why
What do you think of the insulation on the AC boxes?
I suppose there is more there than original?
I do not have all of those seals in my DocRebuild complete AC seal kit

Re: Need a diagram/exploded view over the AC STV valve for a 1963-66 factrory AC Corv

Since two of them are required I guess one goes on each side of the fan case.

As Harry said the seal between the blower motor and fan case does not have a good fit
But when reading the instructions it says there is supposed to be a seal between the blower motor and fan case
It also looks like there is a seal between the fan case and AC box(see the link under where it says 2 is required)Individual Outer AC Seals(2 is required of seal G )
That must be 1 seal(G)between the blower motor and (1 seal G)between the fan case and outer AC box

Seals O,P,S looks like it is supposed to be placed vertical and horisontal on the evaporator itself? Am i wrong about this?

Yes harry it looks like it is so but when i put one of the seals on the blower motor fan case the seal covered the holes for the screws.
It is only the seal for the blower motor/blower motor fan case that is made of rubber in this set. The rest is insulation and that is not made of rubber
Seal parts O and P is to be glued on insulation i have attached so i think i have figured this out

There is only one seal on the non-AC car. A second seal between the motor and case would also cover the holes and the motor could not be installed.

When looking at parts(among these is the vacum for the AC) there is a difference on some parts like early and late 1964



I suppose m 1964 coupe built December 5 1963 is a early built 1964 coupe?
On the pictures is my tool for loosening and tighten the knock off wheels(it is great tool)

Insulation on outer AC box.jpgInsulation on evaporator housing outer AC box 3.jpg
I agree with you Harry but according to the instructions for how to place the seals that came with the AC outer box seal kit says there is one seal on each side of the blower fan case.
I will have to check the assembly manual
Here are the outer AC box with insulation glued on. Still have some more parts to glue on I plan on put insulation on all of the inside of the evaporator lid(the picture to the right)
This is a job i like to do because i can sit in my livingroom and do this. Also parts that have been restored and is going back on the car is great fun

Should i have my brand new US made evaporator pressure tested before installing it on the outer AC box?(i want to assemble the outer AC box and to do that i need to install the evaporator)

I wonder how many 1964 coupe`s with factory AC, 365 hp, 3:08 rear axle, 4 speed manual transmission, AM/FM radio and power brakes was made? I think the car came with tinted glass as well

Roger -

Nobody knows - no records were kept of multiple COMBINATIONS of options - only the number of each individual option that were built.

Noland Adams documents that there were 243 64 Coupes with 365HP(L76) and Factory A/C (C60) produced. I have one but with AM/FM radio, tinted glass, manual brakes and, of course, manual steering. So with power brakes and the other options, it must be less than 243.

Good luck with the A/C. Took a while but mine works perfectly with the old refrigerant. Had the Compressor and STV valve rebuilt, other minor parts replaced. Blows super cold.

STV valve diaphragm that must be turned.jpg
Here is the STV valve and marked in red is the diaphragm that i have to turn before i put the STV valve together Is there anything else than the diaphragm and piston i that is usually checked or replaced when restoring a STV valve?

I marked the washer that sits under the spring blue. From what i see that washer can only sit one way(you can turn it upside down but i have not done that)
If they usually change the spring in the STV valve i think it is no need to do that in this valve because the tension in the spring is really strong

Re: Need a diagram/exploded view over the AC STV valve for a 1963-66 factrory AC Corv

I have insulated the evaporator lid(had to make 4 more pieces to cover all of the inside of the evaporator lid)
Part 1 on the evaporator lid came with the kit. Part 2, 3, 4 and 5 i made myself
The one thing i have left to do is to put on sealant where the insulation pieces comes together

I suppose that it is more insulation inside the evaporator lid do not make the insulation interfere with the evaporator?

I have seen that some are using insulation inside the blower fan casing but i will not do that because if it comes loose i suppose that you will hear that when the blower motor is in operation and the fan is spinning around

The outer AC box on the picture to the right have enough insulation i think

Do you think i have put to much insulation on the inside of the evaporator lid?
