Q: How to remove the accumulator on Chevrolet Astro?
A: To remove the accumulator, start by discharging the system and disconnecting the negative cable from the battery. Then, disconnect the inlet and outlet lines of the accumulator and immediately cap them to prevent any leakage. Loosen the bolts and lift the accumulator out of the bracket, making sure to pour the oil from the accumulator into a measuring cup and noting the amount. For installation, pour an equal amount of the appropriate refrigerant oil into the new accumulator, along with an additional two ounces. Use new O-rings lubricated with refrigerant oil during the installation process. Finally, for both removal and installation, it is necessary to have the system evacuated and recharged.
