Hi I am wanting to do my a/c seals since it is almost winter time. I bought the metal rings and the green rings. The car is only keeping a charge less than 2 weeks. I seen a/c pro makes a super sealer. I know it is a gamble with this but will it work. I know it could clogg the lines or the filter. If I change these seals out do I need to use a torque wrench to torque them down. If not how tight do these need to be. Thanks.

I would never use a sealer they can ruin the compressor evap core etc. As far the lines go there really isnt a torque spec. You just use common sense to tighten then up. Do you know where the leak is at?

Once I get it tight then I should give it a quarter turn. I can not find the leak. I imagine it is the seals because there is black oil stain on the lines where the seals are and also black on the accumulator. My neighbor has the firebird and he had the same problem and he changed the seals and he has never had a problem sense. Thanks.

Some of the lights they have in the kits are junk. Was it just a small little flash light one that takes AA batteries?

Yeah the ez chills are the most expensive ones no matter what size can you buy. Walmart could be more now last time I got one it was 11 but that was a while ago. At the local auto parts store by called star auto I get the 12 oz cans for under 9 with my discount.

Man you are so lucky. I am thinking of buying a 200 30lb r134a tank. It is on eBay and it is new. It is cheaper buying the 30lb than the cans that I buy.

Are you kidding me my parents have memberships. I can get them to get it their for me. I wish I knew that I will have to check with mine. Is it in the auto section by any chance. Also I know you don't have to have a license to buy 134a but if they do require it I am certified and so is my dad I have a universal CFC license so does my dad and I also have a 410a license and so does he.

You shouldnt need it the r12 you did I have the robin air cert. Its in the auto section where the coolant jacks etc are. Take a trip to sams with them before they stop selling it getting towards the end of the season.

Yeah I will do that. Yeah I know you had to have an MVAC license which me and him have also. I just took the MVAC test in 2010. Yeah I know anyone can buy r134a. I just wasn't sure though because the SAMs club here is picky. Let me ask you one more question I have been out of havac for over 3 years is it illegal to vent r134a. Also if I do my seals do I have to have the system refrigerant recovered or can I just vent the little bit that is in it.
