A/C Air Conditioning install GEN IV Magnum VintageAir 1965 C10

[TR65]

I use my truck as a daily driver and it gets pretty hot in SC. My wife also asked me to put A/C in the truck (or else she wouldn’t be riding with me in the summer). So, I set about it.
I corresponded with CoolAir our board member that works for VinatgeAir and he recommended that I use the VintageAir GEN IV Magnum unit because of it’s superior electronic controls. VintageAir doesn’t make a GEN IV kit specifically for our trucks so I had to do a custom install based on their universal evaporator kit.
My truck has a LS2 drive-train from a 2005 SSR and I had the OE Sanden scroll compressor. It mounts low on the passenger side, out of sight so I wanted to maintain that. I also wanted to maintain the ECM control of the compressor. The ECM is set up to protect the compressor and to operate the fans to control the high side pressure, so the fans come on only when needed.
I also wanted to minimize the modifications to the truck, no dash chopping, excess hole drilling etc.
I couldn’t find a real detailed custom A/C install thread for our trucks to I decided to document what I did so it could maybe help someone else in the same boat.
The system works great to date. I would certainly recommend VintageAir.

Wow, you did a really nice job! Can you feel the air blowing on your face with the vents mounted below the dash? My '63 is my daily driver and last week it was around 100 every day. It felt like I was sitting in a dang sauna. My only means of cooling down are a $12 fan that plugs into the cigarette lighter.

Yea, it is NOT a dry heat. Well I was riding in it everyday last week and I didn't have to run the fan much past halfway to be comfortable. You can't blow it in your face but I don't like that anyway.

I Love You Man! I have just bought my evap unit and about to start the install as soon as I rehab from shoulder surgery. You will save me tons of time!!

I suffered in the heat last summer, it is nice riding in the cool.

Thank you very much for taking time to put this together TR. This is extremely valuable information. Hey thanks for posting in your other thread or I would have completely missed it!

Thank you for developing and posting this thread. Excellent information and accompanying photos. The thought and workmanship that went into the project are obvious. I also like the x-brace being bolted in (which had never occurred to me). Admittedly it’s a tiny detail in the grand scheme, but a handy modification for anyone keeping the brace. I’ll be doing that to mine the next time there’s an opportunity.

The drain you designed is certainly more professional looking than many of the holes I’ve seen punched in a variety of floors from back in the 60’s when many took the easy route.

Thanks Markeb,

I appreciate your posts and threads, I have learned a lot from them. In fact, I am figuring how I am going to copy your backup light solution for my truck right now.

Beautiful installation, as usual. One question as I will be doing the same soon, why didn't you use the stock GM compressor?

[coolair]

Dean, It is the stock compressor. Used on SSR's and a few other cars. I like the idea of a scroll compressor as opposed to pistons.
