omfg, due be quiet. its not a band aid... it is actually a fix and the tool your talking about to "withdrawal" freon (its actually called recovering freon and you need a recovery machine) and then you will also need a vacuum pump to vacuum down the system that's the CORRECT way mr gearhead....and is not needed here if he uses the sealer.

dont take me wrong alexus im happy to debate this with you but as i said to jeff this is how/where i make my living. i manage a HVAC supply house i've been at for 9 years and we have over 300 stores nationwide so i do know a bit about HVAC. no, im not a major gearhead and will probably never teardown/rebuild a car motor but i can do most heating/air things in my sleep


OP the freon i recommended to you...(if you had read that post about it, you would know) its a direct drop in for 134, it runs 10 degrees colder than 12 and is cheap (like $11 a can). i have it in my gs430 and can get my air to mid 40's on the interstate (verified with a temp gun) and my old es300 had it and the sealant and it would get down to mid to high 30's on the interstate. you can buy it from probably any HVAC supply house....i know we carry it ( if you pm me i will tell you where one of our stores is located nearby you)
