P0A93 2003 2004 2005 2006 2008 2009 Prius inverter pump failure fixed 

Super straightforward fix, had it done in less than two hours and this was my first ever car project! Thank you for this video!

For anyone wanting to go the inexpensive route. All the tools I needed or used was A socket wrench, 10mm &12mm sockets, A 2 or 3 inch extender. (I had all this and more in a cheap ass socket set I got from advanced Auto for like $5-$10) A flat head screw driver, a Philips screwdriver driver. A set of two metal hose Pinchers ($12 from autozone) with these a little coolant still spilled but not enough I needed to add any. And hose pincher pliers? Not sure if that's what there called but they look like thick hook shaped pliers with a screw on the end of one handle that you use to widen or shorten the mouth. (I used these to squeeze the metal hose clamps so I could move them up and remove the hoses from the broken inverter pump and onto the new one).

This worked like a charm! So glad this was just as easy as the video. Super helpful!!!

Great video. Really helped me out. Took me about 45min. I used the bleed valve to get the air out as well. I used 1/4in inner diameter vinyl tubing from home depot to bleed the air out of the system. It was stupid easy. It was shocking how much air there was so make sure you don't forget this step. Having air in the coolant system is no good. My CEL didn't turn off automatically but I just reset/cleared it with my OBDII bluetooth tool. It's been working great for months now without anymore issues.

This made it real easy for me to follow thx! My inverter kicked the bucket. And your straight forward video was very helpful. For some reason after putting it all back together, there's like a mm of space below the headlight, like it's not quite flush as before, yet everything is as fit as I can figure out. Everything's screwed in. So hopefully that won't cause any issues when it rains. My error 🤷‍♀️🙃

hardest part was removing the headlight on my car. great video, thanks.

best video that shows the easy way to replace it by taking out the headlight for more room. easy peasy 10min job. thanks again

Great video, I can tell that you have quite a bit of experience by your techniques. Thanks

Excellent video, I followed it and did mine in about the same time! ❤

I was going to say why not just use the replacement metal frame but it turns out that the screw that holds the frame down on the left can "die" (break) easily so yeah good idea to replace it at the 3 screws instead.

Funny I just went down the front of the inverter to change mine. A little maneuvering and in and out. Didn’t have to remove the bumper. 2005 Prius.

Great video, bleed coolant

Hi, I popped the same code. When I checked initially, the coolant still looked like it was circulating. Should I still go ahead and try replacing the pump? It hasnt been replaced to my knowledge since I have had the car, but could there be something else triggering the code since the coolant was moving?

The best one on youtube Thanks bro

There are 3-10mm bolt in the area behind the bumper cover that you pull away to remove the headlight. Of the 3 it is the front lower one..........

Thanks helpful video, quick question tho. Will the check engine light automatically shut off after the inverter is replaced???

How should i burp the system of air after doing this? There are 4 or more ways to purge the coolant system of air.

Great job. For the average guy this is harder than it looks but the more you do the more you learn.

So do you not remove the air from the system I’ve seen 2 video they don’t and 2 they do

If I do it this way do I still have to bleed system ?

Thanks a lot for the great video! Really made the job easy.

Did you notice turbulence in the reservoir. I just did mine. The pump is running I feel the liquid going through hoses. Bled the system but no air. Any thoughts? Thanks!

Excellent tutorial. Thanks for sharing

I just want to see the "pump" which I think is the 3 way valve but I'm not sure since showing the part seems to have been edited out of the video

I was told by a dealer ship that pump don't kick on until engine reach's temp

Mechanic ASMR.

Also can you list all the tools you used?

Is this for a 2007 Prius too?

Great video! Thanks

Every video about this replacement glossed over how to unplug the electrical chord of the water pump.

What all do you need to change the water pump? Ty...this is a 64yo female asking. Just in case you're thinking, "boy this person doesn't know much" lol

Thank you, it was helpful

How much was your pump? And will the pump be running if the engine is cold?

Explain how you are removing plastic fasteners. We don't understand just by watching. Don't assume we see what you are doing.
