Well, like a total Dick I stupidly overcharged my AC on the '99 Sunfire because it wasn't cooling well. That blew the compressor and sent debris all through the system. My orifice tube is clogged with metal shards, the accumulator has powdery metal in the oil, and the condenser is clogged too. So I'm replacing the whole system, that's why I posted about the name-brand parts being made in China. This is such a bitchy b*st*rd of a job I want to do it right. I want to weight the R-134 I put in, not just keep adding while watching the temps. I will be using a 30lb can. What can I use to weigh the R-134 without buying an expensive electronic scale?
