Daryl Z71's 2006 Silverado Z71 Re-build

sahls01gmc · March 17, 2015

Compare the first pic to the one on your truck. On the side, you have the electrical connector on the left side, and the piping connects on the right side. Notice the bolt is on the top side, and the one in the 2nd pic shows the bolt on the side.

Long story short, get the first one! Also, make sure you get the orifice tube and clean the lines really well. My A/C works better than most new cars now! And replace every gasket and O-ring possible!

Got ya. It's definitely the first one, not sure why I couldn't see all of that. I have a new orifice tube in my toolbox. I'll also order any gaskets and orings I can find while I'm at it. I'd imagine it'll help out since the truck has 234k miles on it.

They sell a universal seal kit on rock auto. That's where I bought mine

I see two kits listed for mine. Four Seasons brand, and GPD. The GPD one says all seals for A/C, but the other one looks like a kit too. Doesn't seem like it matters which one. Edited March 17, 2015 by Daryl Z71

Seal Kit

You should be in good shape! Make sure to clean the lines out as well. And add the proper amount of oil into everything.

How and what did you clean your lines out with?

sahls01gmc · March 18, 2015

This is what I used:

The bottle on the left is for cleaning out the lines. You just pour it down the lines and blow it out with an air compressor. It also comes in a spray can if you don't have a compressor. I don't remember what color it was when I poured it in, but it came back out black! Must have worked.

Then with the proper amount oil (bottle on the right) and new seals, it was good to go! I used the over the counter freon and filled the lines myself. First time I ever did an A/C job, and didn't have any problems!

Truth be told, I tried to cheap out originally and only replace what I thought was bad. By the time I got it to work, I had replaced everything (what you have listed). It's worth the money to just replace the whole system.

Good luck!

I also had my entire system replaced last year, from the accumulator to the condenser, pretty much errthing was done since the compressor had imploded. This and the tranny are the only things we haven't done at home. Well worth the $$$$ in the hell hole that I live in. lol

Sounds like a plan. Now my last question is where did you pick up that cleaner and oil at?

Daryl Z71 · March 19, 2015

Found the cleaner, but it came in a can instead of a bottle like yours. Found some oil too, but not the same exact type like you have pictured above.

sahls01gmc · March 19, 2015

You beat me to it! I got them both from O'Reilly's. The can is fine, I just wanted to make sure I could blow the lines clean if the can were to run out so I went with the bottle. The refrigerant oil you found should be fine....mine wasn't anything fancy.

white1500 · March 19, 2015

For those that are doing this yourselves, how are you taking care of the moisture evacuation?? Do you take it to a shop after the install but before filling up?

Okay, found mine at Autozone. I'd have preferred the bottle, but they didn't have it. On Autozone's website they recommend this oil.

I'd like this info as well.

Daryl just to let you know I ordered an ac compressor on rockauto.com and mine came prefilled with PAG oil. They said to dump it out from the old compressor and match the volumes to the new compressor. I just hooked it up, forgot to read the instructions first lol. Runs fine but I missed the part that says to match the volume of the old compressor
