What pressure should the Auto ac be charged to for the above car. Thanks in advance
Refrigerant is best filled to capacity by weight, this link shows 28.5 ounces R134a.
Pressures will vary by outside temperature, engine speed, speed of cooling fans, etc. Good rule of thumb is about 30 psi low side, 250 psi high side, measured at about 1500 rpm. Others may now better numbers.
Definitely fill by weight if it is a stock system you have a specification.
