Re: '72 Cheyenne K10
 

[QUOTE=jimbosprint;8790806]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.

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.

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.

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?

Re: '72 Cheyenne K10
 

I ran the passenger vent in front of the passenger defrost. I don't know if this is correct, but the other way pushed the defrost vent out of the dash.

Spare tire is mounted in the bed securely. I got the bracket on Amazon for $29 (Rigid Hitch in-Bed Spare Tire Bracket (RHTC-35L)). I only had to modify it slightly and buy a longer carriage bolt because of the big tire.

Re: '72 Cheyenne K10
 

Yikes! The AC belt stretched a little after a drive across town and it started cutting into the lower radiator hose. I tightened up the belt and pulled the hose down with a zip tie for better clearance. I should probably replace the hose soon. Worth noting that the longer the belt, the closer it gets to that lower radiator hose.

Yowser!! Not a good scenario. You may need to make some kind of a hose guard...

We shall see if this vacuum reservoir helps any with my crummy brakes. I'm too tired to even test drive it around the block tonight.

Re: '72 Cheyenne K10
 

Looks interesting, let us know how it works.

Re: '72 Cheyenne K10
 

I figured out why the truck would start in any gear and the backup lights didn't work: busted neutral safety switch. Fixed!

Re: '72 Cheyenne K10
 

I was skeptical about the vacuum reservoir, and it did not really make any noticeable difference. I think it is an adjustment of the linkage or a bad vacuum booster, but I can't get any shop to work on it.

I hate brakes. Such a simple system, yet I always have problems.

Re: '72 Cheyenne K10
 

The brakes on mine are hard as a rock, also tried a vac canister, no difference. Have a new booster on order with Pickmup, will let you know how that works.

Re: '72 Cheyenne K10
 

That sucks......

Re: '72 Cheyenne K10
 

Maybe that is just the way they are supposed to work? I am definitely interested if a new booster helps yours.

The best way I can describe it: It has functioning power brakes for most of the pedal, but feels like manual brakes at the bottom. It takes a lot of foot to make a complete stop, and there is no way to make a sudden emergency stop. They feel even less safe going downhill. I cannot lock up the tires no matter what.

Re: '72 Cheyenne K10
 

I adjusted my headlights tonight. I should have taken a before picture. The passenger side was pointed at the ground instead of my fence. The bulbs don't match so the driver side is a little brighter, but at least they aim the same way now.

Re: '72 Cheyenne K10
 

Lights are nice and white....

Re: '72 Cheyenne K10
 

Seriously, please, i have a similar booster. all you have to do is pop the master off. You'll see a small stub in the booster hole that should have a hex shaft. That's adjustable. It actually pushes the master's shaft. You should feel it make contact juuuuuust before the master bottoms out on the booster, but you should feel it. Look up master cylinder/booster engagement. They make a tool, but I just did it by feel. I had mine way too far engaged, and the fronts would lock themselves in a couple of miles. I got it all set right, much better now.

Re: '72 Cheyenne K10
 

I did try adjusting that the best I could. However, I don't trust my own work on these brakes so that is definitely worth revisiting.

Re: '72 Cheyenne K10
 

My new Summit ram's horn manifolds (2.5" collector) showed up the other day, and the Calyx manifold dressing showed up today. I have an appointment with the exhaust shop on Wednesday for new 2.25" pipes and 18" Magnaflow mufflers.

man, what a fun posting to read! You have a really nice truck and good luck on your tasks! I look forward to reading updates and I hope at some point I make Chevy Truck friends like you! LOL

Re: '72 Cheyenne K10
 

Just got the truck back from the exhaust shop. It is fairly quiet at idle and has a healthy growl when you give it gas. I'm pleased overall. I asked for the pipes to come out at a 45 (not a 90), but it still looks good.
