What is inverter coolant in Prius?
What is inverter coolant Prius? Inverter coolant cools the device that turns DC power (batteries) into the AC power that runs the electric motor. Has nothing to do with engine coolant. An inverter is a device that turns DC into AC.
What is inverter cooling system?
The inverter converts the high–voltage direct current of the HV battery into the alternating current for the MG1 and the MG2. The inverter generates heat during the conversion process, and this heat could damage the inverter if a cooling system is unavailable.
What does Prius inverter pump do?
Toyota Prius Inverter Water Pump Recall The Toyota Prius has a device on it called an “inverter” which takes high voltage direct current or DC from the traction battery and translates it into alternating current or AC.
What is code poa93?
OBD-II Code High voltage system may overheat is defined as a Inverter “A” Cooling System Performance. The Inverter for the hybrid system utilizes a separate cooling system to maintain proper operating pressure.
What kind of coolant does a 2007 Prius use?
Zerex 1 Gallon Red 50/50 Coolant/Antifreeze.
What is inverter coolant refill?
Inverter coolant cools the inverter that coverts DC to AC current. If you have hybrid, it is what cools the device making power for electric motors. That being low is not good just like low engine coolant is not good for the gasoline engine.
What is hybrid cooling system?
Any combination of Air Cooled Condensers, Cooling Towers, Surface Condensers and Air Cooled Heat Exchangers is commonly termed a “hybrid cooling system.” These hybrid cooling systems are commonly used when water is available but not in the quantities necessary to support a 100% wet cooled system.
How do I know if my Prius is overheating?
Your Prius will be equipped with a temperature warning light and/or a temperature gauge. The most common symptom of overheating is the temperature light coming on. If this light does come on, make sure that you get off the road quickly and safely. Driving while overheating can cause long term engine damage.

The water pump is driven by an accessory belt at the front of the engine, or by the timing belt or timing chain. As the engine runs, this belt turns and keeps the pump working.
What is a inverter water pump?
As part of the cooling system, the inverter coolant pump translates high-voltage direct current generated by hybrid batteries into alternating current for the motor to keep the system at the proper operating temperature. Each part is designed and manufactured to keep key components at optimal operating temperatures.
Why does the Toyota Prius set a p0a93 trouble code?
No matter what the reason, the inverter will overheat and cause your Prius to set a P0A93, Inverter Cooling System Performance DTC. Though the recall covered 2004-2007 Prius, these pumps can still fail on 2008 and 2009 years as well. Toyota did do a part redesign for the coolant pump (part number G9020-47031) to solve the issue facing Prius.
What is the code for the inverter on a Prius?
The cooling system is blocked (kinked hose, e.g.) 4.) The cooling system has an air pocket Regardless of the reason, the lack of circulation will cause the inverter to overheat, setting a trouble code. On the second generation Prius (model year 2004-2009) that code is P0A93, information subcode 346: “Inverter Cooling System Performance.”
What causes a Prius water pump to fail?
If turbulence is missing, one of the following is true: 1.) The inverter water pump has failed 2.) The pump circuit is open (no power e.g.) 3.) The cooling system is blocked (kinked hose, e.g.) 4.) The cooling system has an air pocket Regardless of the reason, the lack of circulation will cause the inverter to overheat, setting a trouble code.
Is there a recall on the Toyota Prius?
