AC install in the Suburban

[Plymouthy Adams]

From bare firewall through fiberboard mockup

[Plymouthy Adams]

transfer to metal, the transisition and the eventual hanging of the unit..the fun part is the wedge that makes up the tunnel for the plumbing..

[Young Ed]

Tim are you cutting a freshly painted firewall?

Tim, as a fellow Suburban owner, and West Virginian I applaud you for your incredible fabrication ability. I hope you are keeping copious notes, and patterns so that I might follow in your footsteps. Sadly I am still unable to get email to reach you, but follow your every move here on the forum.

[Plymouthy Adams]

yes I had to cut it..I backed the inside with a soaking wet sponge to prevent overheating the metal as I used the ziz wheel.. went with a different unit than when I first started out..perils of changing horses mid stream..was not quite what I wanted to do..but it will be fine...the transistioning piece with the plumbing stick out looks right decent and gives you connection room. It would have been a bit hard to plumb it any other way...

Charlie..keeping my pattern handy..have sent you a PM with proper e-mail addy..you get ready for this phase and wish to do the same..notes and pattern are yours..

Tim, I'm sure it will be great when it's done. My hats off to you.

Is that a AC and Heat unit? And who did you get it from?

Looking good BTW.

Danhard..00204HC with defrost

Nice job! I see some er, recycling in your efforts, cough, mil-specs on your sheet items...heheheh and a little sheetrock, I never throw a scrap of that away drives Esmey muy loco:)

[Plymouthy Adams]

no doubt in my mind, the shop where I got the scrap does a ton of contract jobs..the other is some fiberboard I had left over from backing a cabinet...wish I could pick willy nilly out of his left over bin...

Tim, isn't it nice when you get recognizance for your design work? After the car is finished most of the neat stuff never shows. I can see that with you it is the design, build and problem solving that keeps you doing this and not the finished product to drive and show. So many who show have no idea of what went into their pride and joy as all they did was write the check to buy what some else built.

[Young Ed]

Tim that looks like a nice compact unit. I believe you've stated before a preference to mechanical controls-does this one have that? Out of the 5 outputs how many are heat or defrost or AC? Back two defrost front 3 heat and AC?

[Plymouthy Adams]

Yes Ed, this is pure T analog control. The on switch applies and provides power to the thermostat/de-ice trough the safety valve to the compressor. Defaults to low speed at this first setting and then next two positions are medium and high fan. The top lever of my control is for slide temp regualation of the hot water valve. The original trun (screw) operated cable will be for switching to defrost mode while the lower slide will operate the de-ice switch and as it is marked summer/winter..will be the actual mode select switch..getting the analog unit makes all the 1951 factory controls totally useable without need to remark anything. This makes it nice...plus if you have never had a bad propreitary controller go bad..count your lucky stars..the testing and replacement gets involved and expensive fast.

The top two ducts sticking straight up are the defrost dusts and if you look at the one picture of the unit mounted inside, top right of unit you will see the body pinch weld defrost duct from the factory..simple plug and play here the other three will feed the left, center and right dash registers. The unit is compact and therefore perfect for the Mopar with the sunken firewall..

Only real drawback to the 51/52 install is the negative angle that was the need for the pass-thought trough for the plumbing.

Defrost can be hot or cold as to your liking/time of year...it is screw cable activated..

Sad part is I only snag a moment here and there for my cars..but every thing I do today is one less thing for tomorrow..

My project for someday down the road would be AC in the 40 pickup. This looks like it would fit. I was thinking if I ever do AC of mounting one of those 50-52 heater controls under the dash for it. The triclky part for mine will be adding the heater/ac outlets somewhere.

[Plymouthy Adams]

look at my profile page this forum..go to albums..51 Plymouth.pictures of the dash in there with the registers cut into the dash..may give you an idea or two..

[Young Ed]

Here's the dash of the truck I would want AC in. Its very plain and there are no removable parts to add to or modify.

[Plymouthy Adams]

Ed..go to Danhards website..there is a center standing console unit that would probable do well in that truck...thinking back to my 41 Dodge..it would have been a nice fit...
