- This is a 2012 Toyota Prius. We are doing a Inverter coolant drain and refill, it's pretty straight forward and easy to do. We didn't use Techstream so we had to manually turn on the inverter pump to bleed out the air in the inverter cooling system. You want to do this maintenance every 120k-150k miles.

The Toyota dealerships charges $184 per coolant system and at least 2 hours wait time to do this for you... lol. They also will tell you how the price is justified because "its complicated since its a hybrid car and has 2 coolant systems." These videos are a huge money saver for people and you will be able to sleep at night since you know you aren't getting ripped off by the dealership.
Yeah, i did the engine coolant change when i cleaned up the EGR pipe, intake manifold and throttle body. You can access the engine coolant drain after removing the airbox, so don't need to crawl under the car to remove the under body panels
@@yslee1401 how do you access it by removing the air box ?
@@mitchelltomky175 yeah, after removing the air box, you just have to use your hand from the engine bay to access the drain plug, which can easily be turned anti-clockwise to bleed the coolant
Thank you for making this video. My 2010 Prius has 100,000 miles and I think I'm about due for this change
Mines 110k due, gonna do next oil change lol
I hear do it 50k/5y not the 150k they say on the bottle! old red coolant used to be 50k but the extend range they now quote are ridiculous. coolant gets acid and will eat your head gasket and inverter. so cheap and easy to change coolant.
your videos are so detailed and helpful. It's astounding the number "modes" the Prius has. I had no clue these modes existed until I watched your videos.
Thank you! So far, the 2021 sienna hybrid maintenance is the same as the 2012 Prius. Toyota vehicles are pretty easy in terms of maintenance.
I'm a 56 yr old woman and I was able to follow this (hate mechanical work!) However, HATE the fee's dealers and professional mechanics charge even more! I thank you my friend!!
Nice work!
Thanks for your Prius videos. I have saved a ton of $ from not paying dealers overinflated prices. Keep up the good work. My 2010 has 220,000 miles and still going strong!
Have you had any problems with your 2010 burning oil?
How many miles now? Any issues?
@Carolee Overmann No one cares about your scam hacking software. You need to develop some morals. Didnt your parents teach you to be a good person? Do you really think you are going to have a better life by promoting scams in TH-cam comments? Go make something of yourself.
@Carolee Overmann I bet you get through a lot of rent boys 👦.
There is a sticker on the inverter coolant reservoir stating that the coolant change interval is 150,000 miles. What i did on my CT200H (same engine as 3rd gen Prius) is to change the engine coolant at 80,000 miles and both inverter and engine coolant at 150,000 miles
Hi There
Did the inverter and engine coolant change as well as transmission fluid change on my 2012 Prius all by myself (first time ever) by watching your videos.
Thanks a lot. And keep them coming.
Vikas
Nice work!
@@NutzAboutBolts Hey what inverter coolant did you buy the link for the coolant in the description does not work ?? exact name or brand and does the coolant from the radiator and the inverter use the same coolant correct?
Is not tank for transmition fluid?
@@NutzAboutBolts Could i use Prestone coolant instead of the Toyota coolant? Thanks
@@tardeliesmagic NO and HELL NO !!
Hi there, This might be a dumb question but it looks like it in video but I was wondering if engine and inverter coolant are exactly the same. Love your work. Your the one to watch on TH-cam when it come to this stuff. Simple, to the point, no BS.
Yes, they are the same fluid.
Thank you for asking this important question!
Thanks for your video tutorial! I just did some major maintenance on my vehicle and saved hundreds of dollars doing it myself by just watching your videos! I'm an IT guy so not really a mechanic but this was soo darn easy to do! Thanks again!
Thanks for posting this very informative video. I have a 2010 Toyota Highlander Hybrid that needs this service plus the transmission fluid change as well. I am at the 70,000 mile mark right now. The local Toyota of Melbourne wants a small fortune to do these two tasks which I would do myself if not for vertigo. I crawl under a car and immediately get nauseated because of this issue. I have a local ASE certified mechanic in West Melbourne that i can take my vehicle to and have these maintenance items accomplished for much less that I was quoted at the Toyota dealership. People need to be very careful about being gouged when they bring their cars in for service at dealerships!
I just called Toyota. $3XX.XX for THIS. "WE FLUSH." That system doesn't need a flush. A straight change will be fine. I do recommend driving the car and rechecking as a stubborn air bubble might be in there. P.S., they said the parts/labor is about 50%-50%. Did you see $150 worth of labor in the video? I didn't. They wonder why they never see their vehicles after the sale.
Wow, I saved $150 today thanks to watching this video that explained the " do it yourself " process very clear, after watching the video 3 times it was a piece of cake😎
Yes I’m gonna do it myself what tool do I Jed for this and how much coolant do I need to put in Toyota 2015? Thank you
@@passangsherpa6831 5qt/1.3gal for engine, and 1.6quart for inverter. 2 gallon did both exactly on my 2014 prius.
This was the last done since the engine undercover removal is a pain in the butt, so I did trans fluid, two coolants all at 103K miles. It is wonderful to feel car's power to transmission being tightly coupled. Thank NutsAboutBolts for sharing.
Thanks your video it helped alot! For info should it help anybody it is very similiar process for the LEXUS IS300H 2014-2020, the only difference is there is a white plastic drain valve for the Inverter & it is on a rubber hose.
I feel these procedures will be the same throughout the hybrids for Toyota and Lexus.
Thank you very much, your videos of the Prius also work for the Toyota Camry hybrid (2012). I followed your procedure for the invertor and engine coolant on my Camry hybrid and it worked like a charm. Also the 10mm bolt was the same. This procedure will probably work about the same for all Toyota Synergy drive systems. Your video was a life saver because there aren't any videos out for the Camry hybrid.
How did you do yours I have 2007 Toyota camry hybrid and want to do this
What’s the part number for the bolt gasket?
No need to replace
I believe this service costs $160 at the dealer, thank you so much, learned so much by your videos!!!
Do they do this at the dealer at a certain mileage? My prius has had every recommended service it's whole 176k life
@@brandoncostner7437 at 150k they suggest to change the inverter coolant.
290$ in NY -_-
Just the tutorial i was looking for, cheers mate 🤙
Do you happen to know if the inverter coolant and engine coolant change procedure is the same with all Prius models? I have a 2013 Prius C so it's a little smaller. Not sure if the engine is the same or not.
I believe the Prius c uses the 1.5liter engine
Can inverter coolant be done with front wheels up only, or does it need to be level like for the transaxle?
Really nice video. Thanks, Mr. Nutz. Two tips I discovered while doing this 1) a 10 mm hex socket for the drain plug is essential. Don't try this with a 3/8 or any other size or you'll strip it and you're SOL. 2) If you live in an area where salt is used on the roads, that drain plug gets rusty and a breaker is essential to loosen it.
Hey, thanks for the videos it helped alot. Do you have a video on a radiator support replacement?
No sorry.
I wish you could do my service for my Prius. The Toyota dealerships in the Bay Area charges an arm and a leg for these work
How much did it cost you?
Thanks for making this video. Very detailed and informative. Can you make for for the inverter coolant pump replacement?
currently our inverter still working... once its not, we'll sure to film it. sorry!
Don't you have to bleed the inverter system as well, or does cycling the power on and off do that?
Be very careful of which Anti Freeze you buy as the ZEREX PINK COLOR G40 IS NOT the correct chemistry for ASIAN CARS it is for EUROPEAN CARS? ZEREX makes a RED color for ASIAN cars HYBRID when mixed with PINK it changes color, WHY DID VALVOLINE even make the same color for FOOLS LIKE ME that wasted my money I called VALVOLINE and the run around was wasted? TOYOTA charges more for the REAL PINK COLOR that makes the correct specifications.
Good video very good information 👍
Hi Mr Nutz & Everyone.
Is the coolant must be Super Long life 50/50 Prediluted Pink color? I purchased a Toyota Long Life Coolant Factory Red Fluid from Amazon. It need to dilute with distill water. It is the same after diluted and can it safe to use on Prius Gen3. It's Toyota part No 00272.
Ryan Hsing this is not the one you need , yes has to be super long life ready mix pink colour
The colour pink and red are different products. Best is to use the correct one which is pink
What does the inverter do? Does it convert DC electricity from the hybrid motor to an AC current for the electric motor?
during driving, the inverter converts DC power from the HV battery to AC power for the motors. during deceleration, there's diodes that converts AC to DC back to the HV battery, motors and also helps with the regenerative braking system.
In addition, it contains the 12V 100A DC-DC converter for the 12 volt system.
the way to check this pump is working is observing the surface of the coolant reservoir and watch for turbulence like in the 2nd gen
This might sound dumb but I bought my car used and the fluid looks exactly like the fluid you just changed... How do you know when it needs to be changed?
Is there a fluid tester for this? Is there a noise that occurs?
airos52 there should be lines on it that indicate "low" or "max" when its on low or below low, it needs to be changed I assume. I could be wrong lol.
@@kingkav6589 Lmao wow, yeah you're very wrong. Probably shouldn't give answers to matters you're not sure of smh. The fluid should be changed based on the maintenance interval per the service manual.
I am looking for a video on replacing the hybrid water pump for it.
Great video When you put the car into Ready mode to bleed the air from the Inverter reservoir do you allow the engine to start or are you quickly turning it off? Any help appreciated. Thanks in advance!
No, we only power it on to cycle the inverter to suck in the coolant and turn it off
Thank you for the video. I just changed my 2012 Prius engine and inverter coolant today at 191708km. Instead of removing the whole engine cover, I simply removed the driver's side clips. Those darn clips took me over an hour to remove. I had a screw driver and a clip remover tool that looks like a pair of pliers. Unfortunately, I stripped one of the inner bolts due to rust. With the car jacked high enough, I was able to bend the undercover and reach for the inverter drain plug. The inverter plug was tight so, I had to use a short breaker bar (18").
I filled the inverter reservoir about 3mm above the fill line and asked a helper to add coolant as soon as he sees it drop. My helper did nothing and the first time it dropped to empty. I hope this didn't mess up anything? There should already be air after the inverter pump as the air came in from the plug when it was removed. Took it for a test drive and didn't see any codes.
| the first time it dropped to empty
I too had this happen. I did the ready+stop 3-4 times like the video and it dropped a little, but then the engine decide to start and I killed it right away but the reservoir was empty. at the end I put in 1.6qt for the inverter (~5wt, or 1.3g for engine). drove and no issue.
Hello NutzAboutBolts, Do you need to put the car in Maintenance mode to do this service?
Thank you so much for all the asome videos.
No
Pls may I know what will happen if I use tap water instead if coolant in my prius inverter hybrid system?
You will fry your electronics
Dealership asked me to pay 500$ for these easy steps 😂😂😂 I will do it by myself thanks for your video
😬
what kind of gasket is that? i am trying to find the item to purchase. thank you in advance.
No need to replace
24x18x2mm aluminium washer same as gearbox oil torque to 35Nm
My inventor coolant is at e i have a 2015 Toyota Prius c i see the line is not far apart from full and empty do i need to change to whole coolant thanks ?
What’s the mileage?
Mr nutz, do I really need 2 gallons for this? I'm also doing the engine coolant change. Would 3 gallons be enough for doing both engine coolant, AND inverter coolant? Thank you...
Yes
Hello,
Do i have to drain it, or can I just top it off?😳
You drain at 120k miles, you can top off before that
is a full drain required? Wondering if there's anything against just topping off the coolant when it looks a little low.
Yes. Coolant goes bad over time and can even become corrosive. Luckily This kind of coolant lasts a very long time and only needs to be changed about every 7 years
Thank you mate your videos are great it helped me a lot , saves me lots of money. Keep going men you are doing great 😀😀👍👍👍👍👍
I have a 2011. Changed out engine, water pump, sensor and thermostat. I have issue when I drive high speeds 70-80 mph up hill. Reservoir hot but not boiling like before. Temp red light would turn on or flash and then when I slow down it will eventually turn off. My mechanic replaced literally everything minus the radiator and the inverter coolant pump. Can anyone please help????
No codes or no check engine lights just the red light engine temperature turns on when driving high speeds up hill for long periods of time.
Is the issue temp sensor on EGR pipes?
My mechanic has replaced with all OEM parts. Any advice?
Toyota service rep says might be inverter water pump, radiator clogged up, or water pump
Why is so important to replace de coolant rather than just filling it ever since the drained coolant looks as new as the one to be replace.? Thanks.
Because overtime, heat from the engine will dissipate the chemical compound that’s in the coolant that prevents the engine from overheating. By just refilling the coolant when it’s low and not doing the drain and refill, you’re just diluting the coolant effectiveness overtime. It wouldn’t be 100% effective in cooling the engine, so it’ll start damaging your engine by overheating.
Can I use Prestone or other mainstream brands Coolant which is much cheaper than Toyota's brand?
No because they will sludge
Help my hubby did everything on your video and now the car won't start.. what went wrong?
Is the battery dead?
Ok but I need that reservoir behind what you changed changed it’s bone dry how do I get the fluid
Which fluid reservoir? The inverter coolant reservoir?
God I love working on electric cars, they are so much cleaner to do maintenance on. Nothing like my F350, Camry or the Jetta TDI. Never again. Never again.
Michael M lol, the new Camry isn’t too bad. All the other car is a POS 😂😂
@@NutzAboutBolts lol 😂
Thank you for the video. Actually, took the invertor radiator out (it broke), but do not what screws/clips go where. Do you have any video or a diagram you can refer me to on the internet. Which screws/clips go where. Thanks !
Video tutorial is wonderful! I can follow instruction and do it easily, not spend $200.00 and 3 hours waiting on line. However "its complicated since its a hybrid car and has 2 coolant systems". One coolant you show me, which one is another? Please explain to me. Thanks Very much.
hello greetings I have time following your channel and I know you know many of these hybrid cars. I have a problem for some time my car is a 2007 prius with 115 thousand miles. At this moment it cannot be driven and throws the code p0a78-287 which speaks of the inverter. I changed the inverter and it did not work and I have tried everything even with the original toyota program to be able to scan and remove the subcode but I am afraid to change the transmission which is the only thing I am missing and that is not the problem ... do you recommend me ? Sorry if you don't understand some words, I'm already using the translator
Anyone know where the drain plug is? Is it near drivers front tire?
Hi are you using Toyota brand fluid here?
Yes
When cycling through ready mode, is your foot on the brake pedal?
We step on the brake pedal when we’re ready to hit the power button. Make sure to turn off the vehicle before the engine turns on.
Hi
How to replacement the inverter water pump toyota prius 2010
Thanks
it looks like you have to go from underneath but not too sure... we haven't done one yet.
I took Engine radiator and Invertor radiator off. Now I do not know which pipe goes where. There is one pipe come from Invertor and another from the transmission area. I am pretty sure these hook up to the invertor. Appreciate if you can confirm...
How long do you wash hands after getting antifreeze on bare skin? I usually wash for 1 minute with soap, constantly rubbing hands.
Antifreeze on skin isn't all that dangerous, though it can cause skin irritation/rash. I usually just wash my hands normally & have had no problems. Drinking it is deadly, and that includes pets like cats & dogs, so please dispose of the used antifreeze at your local auto parts or wherever you can safely dispose of poisonous fluids, & don't just flush it down the toilet or pour it down the sink.
@@deniswauchope3788 If something can make you blind or kill you, why would want trace amount of the substance. Even auto parts store do not take it. I have to go to hazardous waste facility. Do you really want something like this touching skin - even trace amounts? Over long term, it can have health risks. I wash my hands 20-30 times when I work with it, even with nylon gloves on.
Hopefully this will be the same for my 2016 Prius. Looks like TH-cam is removing Car repair videos -_-
Question since I just got a 2010 Prius.... for the Inverter coolant drain system can you pull a vacuum to refill the system? like using an AirLift? I'm in the process on learning about hybrids right now... As for the Engine coolant system, I presume you can pull a vacuum ...
Don’t need to pull any vacuum. Just refill and turn on and off the engine to have it sucked into the inverter.
@@NutzAboutBolts Thanks....... now what about the regular engine can I pull a vacuum?
@@haywardkong1213don’t need to, let gravity drain the fluids. Just follow the video and you’ll be fine.
Very concise Video. Thank You. I assume this is the process I follow in the replacement of the inverter coolant pump.
is this work as per the shop manual?
yes.
wow the old fluid looks so clean. is it because it wasn't driven much or it is supposed to be clean?
I have a 2019 Prius Prime with the 4th gen P-610 transaxle. Is the inverter coolant drain plug in a similar position to the one in this video, on the bottom of the transaxle? I haven't removed my engine under-cover yet, so I can't see anything down there.
I’m not sure since I don’t have a 2019 Prius prime.
I’m not quite at 110k. About 5k short. Can I juts top off till I reach 110k ? Reading low.
My dealership wanted to charge me $200+ to do the inverter coolant change at 106k. Not only am I relieved that it's not necessary till 120-150k, but watching this video I feel confident I can do this myself!! Thank you!!!
Anyone can do this 👍🏼
do NOT wait for the published 150k long life. all the reviews I see say to to 5y/50k as collant get acidic and you are wearing your head gaster (much bigger problem) and inverter. Cost $30 worth of coolant and
@@alaind831 Agreed... but you can also do test strips to see how the coolant is doing too.....
Very calm video. Its like watching Bob Ross maintain a car.
I want to drain the inverter coolant when it is very hot. This will remove all stuck garbage. How do I go about doing this?
Couple quick questions:
1: When you cycle on and off are you pressing the brake so the engine comes on?
2: you don't have to put the car in maintenance mode for this procedure?
Yes, you need to step on the brake pedal to run the engine for a few seconds and turn it off. You just want the engine on to suck the coolant into the inverter. No, you don’t need to put it into maintenance mode.
@@NutzAboutBolts according to the prius owner's manual, the inverter coolant doesn't need changing until 150k miles, and regular coolant at 100k. Is there a reason why it should be changed earlier than that, other than topping it off if it gets a bit low?
@@TerryUniGeezerPetersonI’m down there replacing the engine coolant at the same time, 2 birds one stone type of deal, if you want to wait till 150k, that’s fine too, I change mine at 120k. That’s why I listed as 120-150k. Also depending on different climate. Harsher weather you want to change it earlier too.
@@NutzAboutBolts oh, my mistake, I must have missed your mention of mileage intervals. Thanks for clarifying.
@@TerryUniGeezerPeterson no worries 👍🏼
Can do this wish i have garage
Nice video and nice voice lol. Im excited I get to charge more for this coolant flush
thanks for the informative video, however, i have small question. do i have to remove the whole engine undercover?or it has a tiny removable/ portable part such as for oil drain? is there any way to remove the coolant using suction machine?
you will have to remove the whole under cover to get access to the bolt. There's no way to use a suction machine for this process.
Hi, can you use that type of coolant in the engine too?
Yes
How do we dispose of the coolant?
Kathleen McKee Firestone, any automotive shops
Oh one more thing... what gasket do you use for the inverter drain plug? By any chance would be be the same gasket as the transmission drain and fill plugs?
this the gasket I use amzn.to/42OsRfL its the same gasket for the transmission drain plug
@@NutzAboutBolts Thanks again :)
@@haywardkong1213 no problem 👍🏼
Manual says every 50k miles after the first 150k (or first 100k user pref). It's been another 50k (i'm at 230k), time to replace. I think reasoning is because it is sealed from factory? Maybe every 100 to 150k miles won't hurt? I don't know so i'm sticking to the manual. Thankful for the prius videos.
Great video. I'm a mechanic and just needed a little refreshing on what do do. We don't see many of these where I am.
Prius bad coolant
Jose, is the plug and process the same for a 2016? Great videos!
How often you have to drain and change the coolant and the converter coolant change?
120k miles
Thank you
Is the invertor radiator system different than engine radiator system. I have Toyota antifreeze (50/50), but plan on getting concentrated antifreeze (100) asian car version - diluting to (50/50). I will not mix, but use one for engine and other for invertor.
They’re both separate system
The Toyota super long life coolant the right one to get?
Yes, they’re 50/50 premixed already, they’re the pink color.
Will 2 gallons be enough coolant to do both inverter, and engine cooling systems?
Yes, I used 2 gallons for both
@@NutzAboutBolts Thank you so much!
Dealers are robbers
very helpful.....
It would sure be nice to know WHY changing it is so important because what will happen if you DON'T change it regularly... NOTHING mentioned in the video... Not wanting to change it because I have nothing better to do.. or money to spare.
You could always google your specific question.
Can you vacuum fill coolant inverter tank??
Never tried it.
My car is making this noise 5:46 every 20 seconds. What do you think causes this
How often do I do this service? Just bought a 2014 pruis 1st time owner, I notice that to level is on the "Low" line is this normal? Also How often is oil changes ? TY
Coolant is 120k, you can do it early too. Oil change is every 10k miles.
Is yellow coolant okay to use instead of pink?
It’s an aftermarket coolant, we only use oem
My car ran code p0c73. Any advice on the first steps to repair?
Did anyone else only get 1.5L out of the almost 2.75 system? Working before and after, wasn’t low to start. No air bubbles left.
Does the car need to be level? I only had the front of the car on jack stands if that makes the difference.
You dont show the coolant yoy are using?
It’s in the description box
Your torque wrench in your link and specs to torque down don’t match, you would need a torque that goes up to 348+/- in/lbs
Does it actually need to be torqued to 29ft/lbs or was it just a typo when you meant in/lbs and not Ft? Thanks otherwise, looks very easy, I’d be happy to do it when this gets answered!
Cool
what brand would you recommends? or should i get it from the dealer? excellent video man. by the way your voice sounds like you just chilling. lol
Most place sells Toyota coolant 50/50 premix. Make sure to get the pink coolant.
Thank you so much, You did the best job detailed.
When you repeatedly turn on the car, was the A/C running as well?
Air Conditioning has nothing to do with this.. this is coolant that literally cools the inverter.
Wait. I just compared info in description on both engine and inverter and it does say "Toyota Super Long Life Coolant" So nevermind my last question. Awesome work. Thank you.
cant you just suck it out from top with a suction pump?
that wouldn't be considered a drain then. it would just be sucking the fluid out of the reservoir and refilling it.
What will happen if u use water in place of this pink coolant ?
Most likely blow a head gasket
Nothing in short term and a lots of trouble in long term
Corrosion, failed pumps and blocked passages, complete inverter failure also possible
@@toninocars what if I wanted to flush the engine coolant with distilled water for a few minutes ?
