A/C charge port located on 1990?

[Guest reatta71]

Hello, I found one port on the driver side by the radiator near the round alluminum dryer? Where is the other port located? Which one should I use to charge? Thanks

[Guest Mc_Reatta]

You want the one on the accumulator itself. (either one if there are two)

The one you found and the one under the cowl cover in front of the driver are the high pressure ports,

Only use the low pressure port, is your Reatta still R-12 or converted to 134a?

Hello and Thank You for the responses. The a/c is 134a. Where is the low pressure port located? I see the one by the accumulator by the front driver side headlight area but cant find the other?? Thanks in advance.

The port on the accumulator or on the line going to it is the low pressure port. One is all you need. If you have two low pressure ports I doubt both will have the 134a adapter installed.

Ok I understand now.. There is 2 there I believe..Let me check tomorrow to see which one fits my gauges for 134. Thanks again for all the help!

The connectors for the two sides are different whether for R12 or 134 so the low pressure hose (usually colored blue) will not fit on the high pressure side. For R12 you need an adapter to connect the high pressure hose (usually red). For 134, it is a different sized fitting. The charging hose (usually yellow) likewise will only fit on the low pressure connector.
