A refrigerant compressor will be hot when running whether or not the charge is too high or too low. If the charge is too low, the compressor will cycle on and off. If too high the compressor may not run at all.
Excessive refrigerant charge, or (less likely) a blockage or kink in the high side piping.
Excessive superheat, caused by a low refrigerant charge.
You can find the refrigerant charge port on top of the air conditioner compressor. The refrigerant charge port will be labeled as the low pressure port.
No. You will risk injuring yourself if the can of refrigerant blows up in your hand.
r 134-a
You cool it and run it through a metering devise.
Your recharge your air conditioner with the type of refrigerant which it was designed for.
Depends on ambient temperature and level of refrigerant charge low charge will not build sufficient head pressure to turn compressor off high charge will cause high head pressure and therefore a "short run" cycle
Check the refrigerant level. Your vehicle probably uses 134A refrigerant so it shouldn't be too expensive. If the refrigerant level is low, someone can add refrigerant for you or you can purchase the tools and do it yourself. Refrigerant is added with the engine running, and to the "low" side. Never allow the "High" side to be over pressure.
Because it's the only way to recover it. You recover from the high pressure side, and charge it on the low pressure side.
