Question
Do you have the specs for the high and low pressure readings for a 2003 Dodge Ram 3500 pickup?
Hi Tim
All books say your readings should be 35-45 low side and 175-225 high side, but that depends on your ambient temperature. So if your temp. is 60-80 degrees those pressure should work for you. If the temp. is 80-97 your pressure can be in the range of 40-55 low side and 225-275 on the high side. If you can weigh the refrigerant you should add
26 oz. of R134 from empty
