Riding around in southern Louisiana Friday and i see freon leaking away. First I thought it was an engine fire, only because I haven't gone in for the recall, got home popped the hood, and... Both high side and low side rubber pieces had holes in them. I ordered new hoses from OEHQ.com(great site by the way), and it seems i can do this by myself. Looks like I'm gonna have to remove the air box and master cylinder. Anyone else ever have to tackle this problem? Let me know. Thanks.

I'll give this one a try...Changing an A/C hose assembly is one of the easiest jobs you can do under the hood...Just be sure to use new o-rings and replenish the lost refrigerant oil...I would be more concerned with why they "burst" as that's almost unheard of...It would take tremendous pressure to do that...Can you post pictures of the hoses?...

Also this would be the perfect time to replace the drier and orifice tube if the system has been open in Louisiana humidity for any length of time...

Next consideration is whether you have the equipment to draw a vacuum on the system after repair and before re-charging...If not, you'll need to hire that done... Exclamation ...Ben

Here's a tip. If you think it's spelled Free-On, leave it the hell alone. Take it somewhere before someone gets seriously hurt. It's Freon. And the stuff in your car technically isn't freon. R134a is an HFC, whereas freon is a CFC.

And if your Impala has ABS and you have to remove the master cylinder, bleeding the air from the master cylinder requires a Tech II if I'm not mistaken.

I really don't understand why you need a license to purchase refrigerant for residential and commercial A/C systems but not for automotive systems.

That would be correct. When I replaced my brake lines last year, I thought my master cylinder was shot. Figured it wouldn't be a big deal to replace, but I quickly learned that its pretty much a dealer job due to the need for a Tech II to bleed the damn system.
