Procedure
-
Place the vehicle on the
2-post lift.
Tip: Ensure the vehicle is not charging.
- Open all doors and lower all windows.
- Place the vehicle in Service Mode by using the touchscreen. See Service Mode.
- Unlock the vehicle gateway. See Gateway Unlock.
- On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap Run, and allow the routine to complete. , click
- Disconnect the LV battery power. See LV Battery - Li-lon (Disconnect and Connect).
- Remove the rear skid plate enclosure. See Skid Plate - HV Battery - Rear (Remove and Replace).
- Position a coolant drain container underneath the LH rear of the HV battery.
- Disconnect the LH coolant hose from the rear of HV battery, and plug the ends of fittings as soon as possible to avoid coolant loss.
- Remove the fir tree clip that attach the coolant hose to the rear subframe shear plate.
-
Disconnect the rear drive
unit inverter inlet tube from the LH rear of HV battery, and plug the ends
of fittings as soon as possible to avoid coolant loss.
NoteCoolant loss greater than 1L requires vacuum fill.
-
Attach the 90-degree coolant
drain hose adapter to the PCS outlet hose coupling.
NoteMake sure the locking tab is fully seated.
- Attach the coolant drain hose adapter to the coolant hose extension.
-
Attach the coolant hose
extension to the coolant drain hose.
WarningThe coolant may spill. Make sure to wear safety glasses.
- Position the coolant drain container underneath the RH rear of vehicle.
-
Disconnect the rear PT
supply hose from the rear of HV battery, and plug the ends of fittings as
soon as possible to avoid coolant loss.

- Remove the coolant drain hose adapter from the PCS inlet hose coupling.
-
Remove the plugs on the ends
of fittings, and then install the coolant pressure test plug adapter to the
PCS inlet hose coupling.
NoteMake sure the locking tab is fully seated.
- Slowly open the valve on the pressure regulator, and allow the pressure to reach specification.
- Close the valve and wait for 2 minutes to let the pressure settle, and then record the reading.
- Perform the coolant pressure leak test.
-
Wait for another 4 minutes and record the reading.
NoteThe delta should be no more than 0.35 psi. If the pressure test fails, check if the coolant hose is fully seated.
- Disconnect the compressed air from the coolant pressure tester.
- Open the P1 valve to release the system pressure.
- Remove the coolant pressure test plug adapter from the PCS inlet hose coupling.
- Remove the pressure fitting adapter from the coolant pressure tester.
