Ok all, since this is in the heat of summer, I got sick and tired of sweltering in the heat. I just finished up a great pictorial on overhauling the A/C system with LOTS of pics! I cover expansion valve replacement, compressor and drier removal and install, proper flushing and everything in between.

And...I got the air to blow 38 degrees at the vent on almost a 90 degree day with high humidity.

YOU can fix it yourself, so get out and do it!

Let me know if this helps anyone and suggest other items I can do a pictorial on.
When you get on the page scroll down to neat the bottom of the page.

I just saw it in the other thread, well done!

Stuff I need to tackle soon, I'm seeing how hardcore I am before I really need AC in Klaus... it's only been in the low 90s and I can take that but the upper 90s/low 100s are looming so I must act here pretty quick.

I guess I am missing something, I couldn't find anything to do with AC on that site.

Yes you will have to scroll down toward the bottom of the page. I don't know how to put an index at the top of the page that is clickable, so it transports you to the right spot.

I tried everything on the page after the odometer, my computer shows nothing but the return lines.

Here is a quote directly from his procedure:

"Not shown is flushing the conedensor and all other lines. You must do this to make the job complete."

Nice writeup, by the way

Hope this helps,

I perused the write up quickly, but since I'm on a dial up I did not wait for the pictures. It was pretty well done and gives good advice.

The only things that I worry about are that a rebuilt compressor was used. The R4 has shown itself to be a poor candidate for rebuilding and I'm personally not convinced about the synthetic oil but it might be the greatest thing since sliced bread.

Good job!

well done site! good info!

everything looked good until I saw the FREEZE 12 refrigerant.

609 Certification

This is my opinion of Freeze12 Dural cool and all the wannabe replacements for R12 Freon.

You can compare the them in this manner....

On one side you have Anaa Kornikova...(R12 Freon) and on the other side you have Rosie O'Donnal (the other stuff).

Sure both are women....they have women parts and they both can funtion as women.

But what would you rather have?
