I did this very job on Monday. Unlike some other people, I received no error codes or warnings. I was driving down the street doing 40 mph, and my car just shut down. I slowed down, rolled into a neighborhood, and waited for the tow truck. I googled while I was waiting the 3 hours and determined it was in fact the AM2 fuse due to the inverter coolant pump going bad. Got the car home that night. Did the job the next day. It was hell, but I got it done.

After watching this a few times, I still don't understand how yall accomplished anything without removal of other stuff. You go from removing the 2 inverter bracket bolts and then next clip "we got it out." Great explanation there guys!!

You check your success by opening the inverter coolant tank and looking for ample turbulence. That's it.

This fixed my prius! Thank you for the video! Very informative. We're not mechanics, and it took us about two hours, but your instructions were awesome!

Thanks guys, this video helped me make quick work of replacing the inverter pump on my wife's 2007 Prius. The original OEM pump lasted an impressive 107,000 miles, so I decided to get another OEM one from my local Toyota dealer at a cost of $171.99 plus tax... OUCH. Would have bought it on Amazon for a little less, but I needed it right away.

Thank you for problem statement (it matched my case) and the unique way to replace the pump, I tried it, but was hard to pull out and work in that limited space. So, I followed another video to remove the headlight assembly. It took me around 4 to 5hrs start to finish. There is easy way to test if the pump is not working, you don’t have wait for triangle Hybrid warning indicator (KZfaq). Also you can reproduce this by pulling out the AM2 fuse. Thanks again, wouldn’t have done this without this video. First time I fixed something major in a car.

Last week I bought a one-owner 2005 Prius for my daily driving, which I had pre-purchase inspected. All was well. The shop gave me a thumbs up. Then… Literally on the way home from buying the car, while in the middle of nowhere, my car went crazy! Mass warning lights. I had No cell signal and was 20 minutes from the next exit. So I gingerly drove, PRAYED and in 25 minutes was at a Toyota dealership. It was the inverter pump. Cost me $671! What choice did I have? Needless to say I was off to a bumpy start. I’m praying it’s a fluke, lol!! A friend of mine who works on Toyotas is flying in next weekend and will do my front and rear brakes, all fluids, all filters, the water pump, all belts, pretty much everything he can fit into a full Saturday and half a Sunday. It’ll cost me a fraction of what I would pay from a dealer. Basically, I’m all in on this car and hoping I have not made a terrible mistake with this investment. 😎

All I can say is thank you and everybody reading this should learn how to work on their own car because these car mechanic places all they're doing is Google in it and following the instructions just like you would except for the fact that they won't run off with your money 🔥💵

Great vid. Didn't realize just how easy this unit is to access - should have done this two years ago just to prevent this problem - and yes, my pump is dead. Tested it. Since the car is a 2009 w/300K miles, it was bound to occur any time. Also, I have the Prius touring model so the car does have the self leveling headlights and it is still a breeze to remove the pump. And no, I certainly did not remove the head light - lol. All one has to do is first, removed the coolant lines (and used proper hose clamps for that job; these are extremely inexpensive plastic ones and they work great so really should get them for this job. Don't want to replace a hose!) Then in order to remove the third bolt under the leveling mechanism just use a short, open end 10 mm wrench. Easy to reach, and there is plenty of room to both access it and remove/rotate the bolt. I can honestly say, this is the simplest pump on a Prius to replace as far as access - which there is more than enough.

Hey fellas, hailing from down under here (Australia). Thanks for the video. I checked a few videos out before following yours mainly because unscrewing and lifting the inverter up to get at the pump is a lot less trouble than removing the front headlight, etc., (that other videos suggest). It was a pretty easy fix, on my own with the help of my neighbour's tools (a ratchet that reaches around corners is helpful). I haven't done any mechanical work for decades, so I'm pretty pleased with myself. Thanks so much! Cheers.

Thank you for posting; I just got off the phone being quoted $611 from the shop to fix; you will save me this money. Nice work!

You can also get to it by pulling out the headlight. Gives you a little more space.

Did you guys bleed the air out of the cooling system after you installed the pump? Also did you look in the reservoir to see the turbulence? Thanks

Thanks guys! It looks not so hard. I had mine replaced at the dealer last year like a DingDong. $900. So stupid I am. Anywho, doing it myself this time. Much appreciated.

I also have a Prius from 2007. I do all the maintenance myself too because it's simple. And it's a reliable car.

Just replaced the Coolant Flow Control Valve a month ago and now this. Almost looks alike, but is a separate unit. Key to know! You must have the right plyers for the clamps! NOTE! Burp the coolant reservoir with 3/16 tubing to bleed cap 10mm or the red shield from hell will appear as to the temp in the inverter will get hot from air gaps.

Drove from San Diego all around Oregon almost 3k miles I went total. I’m an hour away from home after all that and BOOM the danger is popping up and I’m like oh shit not the hybrid battery! Turns out I read a code on the transmission on my ODB and this popped up. Glad it’s an easy job. I had to pay dealership price because I needed the part asap.. $194 jeez. About to hit it right now. I got a 2007 as well as him. Drove 7k miles in 4 months and had no issues besides this.

I think the removal of the headlight gives you much more room to work. It's only a few bolts. About to tackle this soon. More concerned with the bleeding part.

Interesting, when i did my inverter pump it took me 3 hours... i was Door Dashing and was close to my house, so I delivered the food and went to O'Reillys to have them scan to double check and buy the part, then drove home (2 mile drive). I wish I knew about lifting the inverter up... it took me 2-1/2 hours because it was dark and I drained the coolant removed the headlight and loosened the bumper... a rusty bolt fought me on the bumper which took 1/3 of my time... you way looked way easier

To anyone who wants a easy test to see if there pump is working drive at high speeds with AC on High if the air is inconsistent or comes out hot then your pump is malfunctioning and car is over heating cause it’ll be taking a toll on the inverter I have this p0A93 code happen a couple weeks back turned (07 Prius 135+ miles) car off and it was fine since then It comes back like once a week when im running AC/Heater but im getting the pump fixed next Tuesday its been a pain finding a shop that deals with “Hybrid” issues but im scared to order one off RockAuto im buying the part from Toyota for $150 and the shop is charging $200 for Labor (Instalation, Fluids, and draining…etc) which is a good deal I think lol

Watch out for the high voltage when working on your hybrid.Anything orange can potentially kill you if mishandled.

Good video and yes it is quick to replace the pump if you have the tools. I had bought the doorman pump and installed on my 07 but pump only lasted 3 months. Signs of failed pump... vsc light comes on and few minutes later triangle of death and when you brake, sound of a bad water pump. Decided to just pay up and get the oem pump from dealership.

That Prius looks good in black!

Wow you are the best you did it in very shortime Thanks for your time we always learn something

Only had my 2006 Prius with 128klms a week in Canada wish I had you two in my neighborhood I have the dreaded triangle hope to deal with it soon thanks for all the great info gary canada

AISIN is the OEM maker of that pump. you can find it on rockauto or where ever. Im buying a $35 pump because of free same day shipping and great review, time is money. Later down the line ill buy the OEM asap swap it out when the aftermarket go down. O and one of the symptoms of it going bad is A/C won't blow cold consistently or at all.

Beginning my binge watch of your vids...

Nice description. Thank you guys.

My 2005 Toyota Prius inverted making a ticking sound when ever push the brake pedal down & when ever I open the door it make a ticking sound . Does anybody know what could be the issue? Also the vehicle won’t go into reverse or drive . My code reader doesn’t detect any issues!! Please help

To trip the triangle for the inverter pump you have to work the electrical system. So driving a lot on battery only will generate more heat and trip it. Unfortunately, I know more about the inverter pump than I would like to. The dealer would not change mine for recall originally and then 4 years later insisted that I change out the good one that I had already replaced. The worst part of it was that it was a defective pump and is out again!!!

I just changed my inverter coolant pump on my 2007 prius, it fixed the code warning, but now the check engine light has come back on but this time its saying my Air/Fuel Ratio Sensor Bank 2 Sensor 1. Could this have anything to do with the Inverter Coolant pump, possibly being low quality? Maybe I got coolant where it shouldnt have been like in the electric wires on the plug that goes to the pump?

This prius 2nd Gen is huge popular in Cambodia , especially in Phnom Penh City. I do have one and it's very liable to ride around town. Actually the price is very expensive in my Country. it's cost 13K.

Great video always enjoyed watching Josh . He is the kind of friend everyone wishes they had. I am very pleased Hoovies garage sent me over.

Elliott, you’ve done it again! You made another awesome Prius video, but with a very special guest this time, with a man who’s got an incredibly outfitted garage! It comes complete with a double, doubled stacked electric wall style oven. Josh is capable of incredible feats of strength from his arms and chest that makes him the human engine hoist.

Did yall have to remove the headlight to change the pump out?

I would have dumped the coolant since it probably needs to be changed anyway, changed the pump then refilled it. Nicely done though!

Seems like I can always trip mine up with having cruise control on all of a sudden something loses vacuum and then all the errors of course with the constant crazy other pump running

Nice video, did you unplug the safety plug? How do you know when it needs to be replaced? CEL code or hybrid assistant to see if the electrical motor 1 and 2 temperature under 200F and so?

Dudes didn't show shit.. Didn't Even bleed the system. Good job

Mustve missed it. What was the symptom that you were trying to force?

If you you are shopping for a car and want to stay cool, save fuel, avoid idling in parking lots etc .. buy a white car. At 700 watts per square yard, the sun really can load down your drive train just to move more heat somewhere else. It's a losing battle.

Min 8:05 In the background the brake fluid is it supposed to be the light color? We have purchased a 09 Prius and it's the same color I thought I might need a brake fluid / bleed job? But most I see online are the same color. Thank you, great videos. We started our (Prius) journey with a first gen did this same job on it not too complicated. Now in the process of rebuilding the hybrid battery system of this newly acquired 09 second gen.

I thought the video was very good but some details needed to be added to make job go smoother. You’ll need a good swivel socket to remove/loosen some of the bolts especially the rear inverter bolt. Rear inverter bolt needs to be loosened about half way to get good inverter clearance. I found after taking bolts out of old pump that because hoses had been on for many years couldn’t get hoses off without putting one bolt in old pump and pulling on hoses to remove. The electrical connector on pump needs to be removed with needle nose plier squeezing on locking part of connector, unable to see d/t wire harness blocking view of locking part of connector. Hose clamp should not be replaced until new pump is positioned so that bolts line up with holes in mounting plate. Job would be less messy and easier if proper hose clamping pliers to prevent fluid loss were gotten before starting job.

What do you use on your headlights?!? 🤩

Can y’all do this to my Prius? Lol I need this done tooo

I put the stock wheels from my BRZ on my prius too 😄

How does it drive on 17s?

Thanks for the video! My moms 05 needs this and Toyota wanted ~$300 in labor. (What a joke)

172k miles.... how to check if waterpump needs changed before it breaks down?

I have the same problem red triangle in screen twice so I wait 10 min until the car get cold and I added antifreeze to the radiator so one more time the triangle come again the Mécanique told we have to change the inverter electric water pump I will change it tomorrow I hope that the pump is the right problem, everything will be good smouthly and I don't want to see this triangle no more

Last week I brought my 2008 prius gen 2 with 141k miles (I bought it last year for 7500 usd from an old couple) to the Toyota dealer in The Netherlands. A big red triangle on the dash with the car and exclamation sign on the touchscreen came up. It said there was something wrong with the hybrid package. The dealer did some reading on the car, and they told me the dc converter did not convert well so the risk of getting a short circuit in the hybrid system is pretty high. They told that the dc converter cost without taxes about 3000 USD, with labour cost it will cost around 5000 to 6000 USD in total. However, they said that when you replace the dc converter it is still not problem free. Other problems that are connected to the dc converter or hybrid system might occur. Is this true? Or is this a protocol of the dealer to communicate such things? They offered me to sell the car to them for 2000 USD. Should I keep and fix it elsewhere or sell the car?

Sweet! Thanks dude! Going to do that on my G1 soon!

Is thia the same pump that was with a high pitch sound in your car?

Going to preventatively replace mine right away on '08 with 248,000 miles. Has never been done.

Holy shit dude you're a lifesaver. I watch all of JR's video and and I've seen you in them along with the other guy and now I watch this video when randomly at 231,181 I got the triangle of death and the POA93 that's triangle of death it would not go away. Our inverter is creating no turbulence in the reservoir meaning it's dead no warning , no blown fuse. but with this now I feel confident go on RockAuto by a new one fix it putting the new one in, thank you so much.

I had a huge service at dealer and I think this was supposed to be a warranty item for Gen 2. Looking at mine it looks rusted like it’s original. Is Toyota required to do recall work if a bulletin is issued? Thanks

These pumps are higher priced now. I guess its because they actually last compared to the original pump.

i replaced mine but my red triangle hasnt went away any thoughts?

Hey... Nice vid!

did you bleed the air out of line?

Love quick and easy fixes!

Did you change the coolant?

Could you tell us what the sound is like on your next video like this just so we have an idea?

these last about 100k miles which isnt horrible but because they're electric they're not as reliable as the belt driven pumps. i've replaced it twice on my 220k mile gen 2

Check the fluid levels. Always.

do you know if prius c water tank also show turbulence

Mine failed at 110k mi a couple years ago and I replaced it like this with a pump from Amazon for $60 (non OEM), plus the cost of some coolant. You can get similar knock-offs for $30 or less. They are probably crap. That pump just failed after about 20k more miles. I will buy the original Toyota part this time if I can get one. It's like $160, but it's the labor. Most people sure will take an hour to fix it, but add in another how many hours of futzing around, scratching your head, putting on the code reader, calling around for the part, waiting for shipping or driving to the auto parts store, figuring out the clamps etc. I don't know about you but a part that is three times the cost but lasts 5 times as long is a bargain in my book. In 12 years I have not spent a lot of money on parts for a Prius! Also, I will add like others that you need to make sure the coolant is actually circulating through the pump and the lines bled of air.

Is this similar for 3rd gen? Thanks!

great video bro

Beautiful 2nd gen.

I'm smelling battery acid. It has a new battery pack I was told when the pump starts going out it does not cool the inverter off properly and it will let off a battery acid smell. Enjoyed your video. I've been trying to find some rims for my car would you happen to know the name of yours

Thanks Guys for a great video.

You know, I have to replace the drivers side headlight igniter also, it may open the world up to take the headlight loose also.

I’m having the same issues with my 2008 Prius it doesn’t say danger on the screen it’s a problem

Sure is a nice looking Prius

Take out the headlight, you’re welcome

So that’s what that circle in the front of the car is for!

The coolant pump and water pump are different right?

Is that pump still performing? I read quite a few negative reviews on Amazon and opted for a cheaper option ($35) with higher reviews.

I bought an aftermarket pump but it looks like the pigtail adapter to the factory pump won't fit the connection of the new pump. I have looked up several of the aftermarket pumps and the connection looks the same..any suggestions would be helpful.

Torque app for Prius

Hi from where did you get the part?

The battery fluctuating like that and the poor gas mileage are good indicators that the hybrid battery is failing.

I love dropping jaws. Most people think a Prius is a dog, I give a lot of people a moment of confusion.

FYI this replacement won’t work for models that have the headlight adjuster. I have a 2008 and spent an hour trying to make it work but this part is too tall. You have to get the one that’s like oem

From testing my car it took 24 km / 16 miles before it would trigger a warning. Was a 30deg C day

When my pump failed the car shut down after 4miles total power out I’m hoping to god that was a protection feature so the car didn’t overheat

You definitely want to bleed the system and top off the coolant after replacing the pump.

Can pump cause you to lose motor oil or cause ac to stop working?

If I tried to do this it would probably be an hour fix...maybe even 2 haha

Easy fix on a 2010 prius?

If the car keeps blowing the AM2 fuse, will replacing the inverter coolant pump fix it, also smokes from driver's side under hood

You'll know if it was a successful swap if the P code disappears.

Awesome!

Nice video and probably the only one on replacing inverter pump on 2nd gen ( though I am looking for on 3rd gen Prius) , assuming it's almost similar process on 3rd gen Prius. So, do we have to disconnect hybrid battery ( pull the orange safety plug on hybrid battery ) prior to this process ? And will it throw any errors after reconnecting the orange safety plug? And , can this pump be replaced from below instead of lifting the inverter ( thus not disturbing the inverter ) ? I subscribed .Thank you

No bleeding air from the system?

I also have the prius. But i think it’s a shame that you can’t take the badges/letters off from the back of rhe car for a cleaner look. With almost every simple car you can do than this times but with the prius you see holes

Thanks 🙏
