Re: what should be pressure in car ac hoses?
The static pressure(engine off) and operating pressure(system operating) will vary greatly due to many factors including outside air temperature and humidity. That is a question that can't be answered in a simple manner.
If you are attempting to DIY air conditioning work you should read up on how they operate and find "the chart" that shows pressure for a properly operating system at the outside air temperature that your car is in. Also keep in mind that AC service is a regulated service. DIYers can do their own but shops needs certification.
