Need more info like year, make and model.
To properly read air compressor gauges, first identify the pressure unit (usually PSI or bar) and the range of the gauge. Then, check the needle position to determine the current pressure level. Make sure to monitor the gauge regularly to ensure the compressor is operating within the recommended pressure range.
Yes, in order for the compressor to take on the new coolant and oil charge the compressor ideally should be running. It is posiible to begin charging the system with freon prior to compressor initiation, however to get an accurate reading of the pressure in the system the compressor should be cycling with differential valve operating properly. If it is clogged or the compressor is not cycling then then low side reading will give an elevated pressure while charging the system. Does that make sense?
The air compressor was indeed created in the 1809 by German Mark Pork. As for where did he make air compressor tank, I have no idea about it but I am happy to learn that too.
Yes
see API 618 description
your torque spec will be 65ft.lbs. Make sure you have the torque sequence too.
95 ft inches of torque , make sure it is in ft inches of torque and not ft lbs.
Yes you need an air compressor that will give you an adjustable air suspension.
I need to know the type of compressor (make) before I can answer that question.
Somthing to do with the AC.
When calculating the torque you would use the lenght of which ever tong that is connected to your load cell.
