Model: Tahoe
Engine Size: 5.3
Refrigerant Type: r134a

Hey guys wondering if you could help me out, hit a deer the other night took out my front end and a/c condensor. Gonna replace it this weekend wondering if you could hook me up with-
how many oz. of r134 it needs
what pag oil it needs
how much pag to put in for a straight condensor swap?

It is an 03 Tahoe with rear air and auto climate controls. Thanks in advance, your help is always appreciated! Stanley J

Pag 46 add about three ounces with dual air..I'd rather an ounce to much than an ounce short.. system calls for 43 ounces R134a but double check the sticker under the hood..Be sure to pull a deep vacuum and charge into the vacuum..Hope this helps..

hey Chic wondering if you could help me out, I vacumed my system verified it held at -29psi, then i tried to add freon I ran 12oz cans through my gauges. the problem was it would not suck everything out the can. seems like it would only take 80%. So i added 4 12oz cans, maybe 80% of each. I got the compresor to kick on steady and blow cold air but it didnt get ice cold. My low side readings where around 36 psi and high side I believe around 175-200. Did I not add enough freon? Im here in upstate NY and it was only 65 degrees out, was that my problem in extracting the freon? Its off to the body shop now so I cant really screw around with it but when I get it back should I try to add half a can to get it up to speed?
Thanks in advance. Stanley

65 degrees is not the best to charge a system, without being sure you can get the proper "weight" into it. But once it's over 70 degrees, and hopefully we'll have some more of those temps, (I'm in the NY area too) then you can charge it by running the AC, hood down, let it get warm under the hood, then charge by feeling the inlet and outlet of the evap...They should be the same temp, with the outlet slightly cooler..Once you get that colder suction line (and knowing you have the approximate charge in it) then you're done.... Hope this helps..
