Remove
- Connect the A/C machine to power, turn the power switch on, and select gas type.
-
Place the vehicle on the 2-post
lift.
Tip: Ensure the vehicle is not charging.
- Open all doors and lower all windows.
- Recover the A/C refrigerant. See A/C Refrigerant (Recovery and Recharge) (Maintenance).
- While recovering, perform the vehicle HV disablement procedure. See Vehicle HV Disablement Procedure.
- While recovering, remove the fresh intake duct. See Fresh Air Intake - HVAC (Remove and Replace).
- While recovering, remove the LV battery. See LV Battery (Remove and Replace).
- Remove the A/C hoses from vehicle.
- Remove the front aero shield panel. See Panel - Aero Shield - Front (Remove and Replace).
- Remove the desiccant. See Desiccant (Remove and Replace).
- Weigh the desiccant bag. This is considered the "wet weight."
- Determine the "dry weight" of the desiccant bag: Inspect the bag for a label that contains the Part Number (P), Serial Number (S), and Dry Weight (W). If the label is missing, or if the dry weight is not visible, assume the dry weight is 90.4 grams.
- Subtract the dry weight from the wet weight. This is the amount of oil that must be added to the system in addition to the oil that was removed during refrigerant recovery. Note this amount for later.
-
Stick a steel ruler into the accumulator to measure the refrigerant oil level inside
the accumulator.
NoteLevel will vary per vehicle. Keep the steel ruler vertical during measurement, and record the measurement in millimeters.
- Multiply the measurement by 5.6 and add 15 to convert it to grams. Record the measurement in grams.
- Calculate the total oil loss from AC recovery, desiccant bag, and accumulator. Record the total oil amount. This amount will be used for oil injection at later step.
