Idk, I was very hesitant to slap a new drier, tube, and compressor on without flushing the system or doing the condenser and evap as well. But we did cause hes poor and I didn’t feel like fronting more money. Pressures are great and it blows cold as can be!

Good job. Orifice tube did what it was supposed to do

Is that its only purpose? For some reason I thought it did something more

Should have flushed

I need to get a compressor at the new house so I could have at least hit it with shop air. But alas we shall see how it goes. The truck is a total POS imo, it’s got a long list of stuff that needs doing and I’d be shocked if he kept it another two years.

Not sure that's its sole purpose, but it does act as a filter.

Filters are good.

Totally unrelated but I did make some new house garage progress. These hexagon lights are fantastic for the price! $100 for those. The tote storage workbench trend is hot and I see why, it’s very easy to build and works great.

Orifice tube is basically the metering valve and what causes the freon to go from a High pressure/liquid state to a Low pressure/gas state. As the gas expands it gets cold.

Good to know. Every time I've had a mechanical failure, it's been full of debris. Good to know it's actual purpose

Looks great. I really like that style of light. Have you considered painting the ceiling black?

Yeah, the filter is there to keep trash out of that little tiny orifice.

Yes but that requires work and more whiter is more brighter

Well it might not have worked completely. Buddy said he heard a knocking sound and the AC belt shredded. I didn’t look at the belt or install it so maybe he screwed it up or it was old but I’m thinking more junk clogged the new orfice tube and the compressor died.

Hard to say. Most of the time when you have a lot of trash on the orifice tube it means the compressor isn't long for the world, or it already crapped the bed... lol

The old one did, we replaced it, the drier and the orfice tube. Pressures were great and air was cold. Key word “were”

Assuming compressor came pre-filled with proper amount of oil. Did you add any extra oil?

I like to add a tad, I always figure a bit more won’t hurt and so I really trust the factory?

I have drained the oil from new compressors and measured to be sure it was the correct amount. You are correct a little more won't hurt but too much could cause slugging and possibly break a belt.

Turns out his tensioner crapped out. He put a new one on and a new belt and has been good for two days. So yayyy!

Keep an eye on it. I thought the problem was my tensioner on my 2007 a couple of years ago because the A/C compressor kept throwing its belt. Turns out it was the compressor on its way out. I took off the A/C idler pulley and installed a new compressor and a stretch belt (I used a 2012 Yukon XL part number) instead of the tensioner-based one. No problems since.

Didn't know you could do that, very interesting.

I forgot to add that it kept throwing the old tensioner belt after I installed the new compressor. I put a camera in there to watch when it would happen, and it was always when I had to step on the gas to accelerate quickly, like merging into traffic. Speculation on the interwebz at the time was that over time, the compressor mounting plane had warped ever so slightly over the 230K miles of heat/cooldown cycles on my aluminum block L92. But who knows. I switched to the stretch belt and never went back. No problems whatsoever in the few years and 25,000 miles since.
