FAQ:

Q: How do you drain coolant from a Prius?

A: You should see turbulence in the inverter coolant container and you should not hear air bubbling in the fluid. Then make the Prius IG-OFF. Drain the inverter/transaxle coolant by removing the 24 mm hex drain plug at the bottom of the transaxle. Do not confuse with the transaxle ATF fluid drain plug which requires a 10 mm hex key socket to remove.

Q: Why is my inverter NOT working on my Prius?

A: Your symptoms are consistent with overheating, due to the pump not working. A short run, on a cool day, will not overheat the inverter system immediately. But the problem is there, as it is on most Gen II Prius, and you need to replace the pump now or face some much more serious problem, like inverter failure.

Q: How can I tell if I need to replace my inverter coolant pump?

A: Start by making the Prius IG-ON ( not READY) and listen to the sound of the old inverter coolant pump, so that you have an idea of where you need to end up when you are done. You should see turbulence in the inverter coolant container and you should not hear air bubbling in the fluid.

Q: How can I tell if my inverter water pump is not running?

A: If you are referring to the inverter coolant pump, you can verify that it is not running by making the Prius READY, then looking at the inverter coolant reservoir, mounted on the side of the inverter, for fluid turbulence. If you do not see turbulence then the pump needs to be replaced. Bryan lasseigne likes this.
