How many cans / oz of r134a needed 2003 AWD

[Hank]

Well after three years of weak compressor I broke down and ordered a kit on ebay. Side note, the one that failed was installed by the dealer under the extended warranty, it went weak a few days after the warranty ended and the dealer wouldn't honor it.

Anyway, harbor freight has 12oz cans on sale. With front and rear A/C how many cans should I get while they are darn near half price?

My 94 required a shot of juice a couple times during the summer, I started using this stuff called enviro-safe. Its only $6 a can and this stuff is ice cold. Its compatable w 134. Good stuff. Its from a place in Perkin, Ill. Not sure if its a local thing or if its available elsewhere.

I started using this stuff called enviro-safe.

Hey zzimmer3,
I researched enviro-safe earliest article I could find dates to 2001 so it's been around awhile. It is suppose to be 32% more efficient, requires less to recharge system, no need to pull a full vacuum and is a direct replacement. You said it's ice cold. How much of a difference in temperature compared to old refrigerant?
Anybody else on the site use the stuff? sure like to hear feedback.

Saved Big Money at Menards, R134A $5.00 or something per can, save your receipt get the 11% rebate later. $$$
Evacuate the entire system Check for Leaks, (THE COMPRESSOR IS USUALLY BAD), prior to charging. Don't waste materials. God Bless the United States of America.

My 1999 Safari SLE with Front and Rear AC took 4+/ 12 oz cans. Get a Fifth can for bleeding the lines.
Check my site for Compressor Rebuild tips. I've done Two rebuilds HT6. Both are working great.
Good times...

I just got my Astro, it's a conversion van. I don't have a rear ac control knob, so taking a stab, I probably don't have rear AC right?
I need to refill, nice chart!

Probably not. It is behind the rear seat. If you did have it there should be a vent on the wall, plus vents on the roof facing the front of the van.
