Inverter Pump and Coolant Question

white spots = aluminum oxide? That is not normal or good. I wonder if some clogging has formed within the inverter coolant passages.

I'd encourage you to have the coolants replaced before your trip, if you can fit that into the schedule.

 

Sounds normal. I cleaned the white/pink stuffs. I made a video when I changed my coolant. Does your look like mine?

I changed the coolant in my inverter a couple of weeks ago and was observing the fluid in the reservoir with the pump running. There was just a gentle motion of fluid, not turbulent or "boiling" looking at all.

 

The pump is one speed so it is not variable.

If I were to imagine on a boat in the coolant, the boat will be rocking and it will make me dizzy and probably throw up. It won't be like a storm or tsunami.

 

Question
If you have bad inverter. You have replaced one inverter pump and have a still had bad inverter. Now you replace inverter should you also possibly replace inverter pump again???

 

Well, you need to decide whether the inverter pump is functioning or not. Here are the indications that the pump is working:

1) Make the car IG-ON (where instrument panel warning lights are on). Does the pump sound like an aquarium pump, without air bubbles? If yes, that is good.

2) Look at the inverter coolant reservoir. Do you see fluid turbulence within when the pump is running? If yes, that is good.

If the inverter pump is running, then there's no need to replace it.

 

Please help me out i have a prius 2004 in which runs good no problem on it, recently around 3 months i replace the P0A93 code the inverter pump the electric one in the fender with a new dealer one and 6 months earlier i replace the other pump down the fuse box the car. my car runs well but after all day using it long tris around town the vsc lights and red triangle lights up, i scan the car and no codes on it, then next day still the same and after driving it a little lights get off if i drive the car in short trips no problem but then after driving long ones lights come on again, then also get the car scan and the code P0A93 return but the part already replace recently, also i try to purge the system but the same problem can someone help me out on getting this solve????
