Remove the reciver dryer and drain. A good portion of the oil will sit there. all of the comp that I know come fully charged with oil. What year of vehicle/
What he said. Excess oil will hang in the bottom of the drier. Just make sure when you drain it put it right back in order to minmize the amount of time it is exposed to open air. Vacuum it down and then charge it up. You did vacuum it down the first time right? If not get an electric vacuum pump from Harbor Freight and have at it.
