north west arkansas | It seems like on the combines the low pressure side will be around 25 to 30. You can use the bubbles, but I never have on anything. On any A/C system once the low pressure side at the compressor starts to sweat the system is fully maxed out and cant do anymore. I personally woukdn't buy a set of R 12 gauges if you only have a couple of cans left. I would just use whatever you have been using and then I would just check the air temp in the cab and check to see if my low pressure line was sweating back. | |
