A/C refrigerant amount in lb.

Does anyone know how much refrigerant (r134a) is needed to properly charge a 98 V70 turbo. I was unable to find the amount through searching the forum.

TIA

Well what did you replace?
If you are only topping it off then add about 1 oz.

You only have a low side port on your car. It is located between the passenger side headlight and ECU box.

There is a black cap on the port. You do everything through the low pressure port.

The top pic is the low side port where you do everything from.
The second pic is the low pressure sensor. If you are low on freon that switch will stop the system from working.
