Looking good.

The ducts are in the dash like spaghetti.

Awesome,......

Re: '72 Cheyenne K10
 

FedEx said my compressor and controls were delivering yesterday but they didn't show. So today I played with wiring for the new gauges. Temp and volt gauges will be custom fit into the cluster, and the tachometer will hose clamp onto the steering column.

Jimbo, you will love your VA unit. Had mine charged Friday and took it out today to the Placerville wine country, high 90's to 100 and blew ice cold. Took no time at all to start blowing cold after starting up in a hot cab. The original AC in my truck never worked, so I can't compare to stock, but I really don't think it would be better than this.

Re: '72 Cheyenne K10
 

Did you put a fan in front of the condenser, or just the regular Vintage Air setup?

Question - does it use a regular factory AC belt?

Re: '72 Cheyenne K10
 

Here's the belt I used, Gates, pretty sure 58" I think which is what VA recommended, stock pulleys. Not sure what you mean about fans, I have a stock setup.

Re: '72 Cheyenne K10
 

Custom voltmeter and temperature gauges are in the instrument cluster. They look good in the daytime, but I wonder how they will look at night with the lights on.

They look good. Don't forget to take a night pic for us.

Re: '72 Cheyenne K10
 

Today's progress (so far):

• The dash is all back together and the tachometer is installed
• The Vintage Air controls are installed
• Compressor brackets sandblasted and painted
• Inner fender reinstalled
• Alternator belt reinstalled

How does an old work truck not have any tie-down anchors? I fixed that.

Here's that night dash photo. The tach ground is not hooked up yet, and I have to figure out why a few of the LED bulbs aren't working.

Re: '72 Cheyenne K10
 

I’ve only briefly messed with my dash lights, most work but not all. From my research it maybe the circuit board that is causing some of the lights to not work. Some of my sockets work and some don’t even after changing the bulbs, knowing the bulbs worked in a different socket. I’m probably gonna order a new circuit board and see if that is the issue.

Re: '72 Cheyenne K10
 

It’s all looking good, great job.

Compressor install was easy. I really appreciate the previous owner using anti-seize on the exhaust bolts. Now I am on the hunt for a shop with the crimping tools to make the AC hoses.

Can anyone tell me if the main power for the Vintage Air is safe to hook up to the battery side of the American Autowire Megafuse?

Looks really good Jimbo, you are flying along compared to how long it took me. And, yes, you can wire directly into the megafuse terminal coming from the starter. I called AAW about exactly the same thing. They also said most people doing the VA install wire the negative lead to where the negative battery cable attaches to your engine. That's what I did too, looks cleaner.

Re: '72 Cheyenne K10
 

I got the AC hoses made and installed. I need a heater hose fitting for the top of the water pump and the heater hoses will be done.

As I suspected, there was no working thermostat. The spring was broken and it was stuck open. I replaced it with a new 180° thermostat.

Perfect, thank you!

Re: '72 Cheyenne K10
 

A trip to the hardware store solved my heater hose plumbing. There was silicone RTV on the plug in the intake, so I put some on the new hose fitting too.

Re: '72 Cheyenne K10
 

I finished up the last details for the Vintage Air install today. Wiring is finished, controls are programmed, fans and vents all work properly, and the compressor belt is on. Duralast part 17580 works well for the belt. (I tried parts 15580, 15585, 15570, 17570, and 17590 which all do not fit). I believe it is finally ready for the refrigerant to be charged!

Vintage Air install is complete! System is charged and everything works! Hot heater, cold AC, and a fan that will blow your hat off.

Re: '72 Cheyenne K10
 

Awesome. Can I have your old AC parts? :)

Re: '72 Cheyenne K10
 

Great and it looks nice too.

Re: '72 Cheyenne K10
 

Nice timing Jimbo, now you can sit in your truck this week nice and cool when it's 108 out!

Re: '72 Cheyenne K10
 

Jimbo,

I am installing a vintage air right now as well. Which hose is supposed to be vertical (ie the dent shape in the cove box)? Is it the passenger defrost or passenger side vent?
