- Position a coolant drain under the rear RH side of the HV battery
- Disconnect the rear powertrain supply hose from the RH underside of the
penthouse, plug the female fitting of the hose, and allow the battery to
drain.
- Connect the coolant pressure test adapter to the RH side male fitting
under the penthouse.
- Connect the hose from the drive unit pressure test fixture to the
coolant pressure test adapter.
- Close both valves P1 (inlet) and P2 (outlet) on the test fixture, and
connect a compressed air supply line.
- Fully close the regulator, and then open P1 (inlet valve)
- Set the pressure regulator of the test fixture to 50 psi.
- Position the coolant drain under the rear LH side of the HV battery
- Disconnect the rear drive unit inverter inlet hose from the LH underside
of the penthouse, plug the female fitting of the hose, and allow the battery
to drain.
- Connect the coolant drain adapter to the LH side male fitting under the
penthouse, and direct the tube to the coolant waste container.
- If the coolant waste container is a bottle, push a shop towel partially
into the bottle neck, to prevent coolant from splashing out.
- Slowly open P2 (outlet valve) to speed the drain.
- Wait at least 2 minutes for the coolant to fully drain.
- Close P2 (outlet valve) when no more coolant is expelled.
- Move the coolant drain under the rear RH side of the HV battery
- Interchange the coolant pressure test adapter and the coolant drain
adapter on the male fittings under the penthouse, and direct the tube to the
coolant waste container.
- Slowly open P2 (outlet valve) to speed the drain.
- Wait at least 2 minutes for the coolant to fully drain.
- Close P2 (outlet valve) when no more coolant is expelled.
Caution:
Though not visible, there is still residual coolant in the power
conversion system thermal block and input and output tubes. When servicing the
power conversion system and input and output tubes, make sure not to spill any
coolant, and to immediately wipe up any coolant that has spilled.
- Disconnect the air supply from the test fixture.
- Remove the coolant pressure test adapter and coolant drain adapter from
the HV battery
- Perform the service procedures that required the penthouse coolant to be
drained.
- After the components have been replaced, refill the coolant. See
Refill.
