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.

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.

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!!

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!

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!

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.

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.

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.

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

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😎

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!

Just the tutorial i was looking for, cheers mate 🤙

Thank you mate your videos are great it helped me a lot , saves me lots of money. Keep going men you are doing great 😀😀👍👍👍👍👍

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!!!

I believe this service costs $160 at the dealer, thank you so much, learned so much by your videos!!!

Very concise Video. Thank You. I assume this is the process I follow in the replacement of the inverter coolant pump.

great prius videos your the best

Thank you for making this video. My 2010 Prius has 100,000 miles and I think I'm about due for this change

Thank you so much, You did the best job detailed.

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.

Nice video and nice voice lol. Im excited I get to charge more for this coolant flush

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.

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.

Good job. Thanks.. Very easy

Thanks for the videos

Good video very good information 👍

And the great videos keep coming.... subscribed!

Thank you. Well taught

Dealership asked me to pay 500$ for these easy steps 😂😂😂 I will do it by myself thanks for your video

Nice video 👍

Awesome looks easy.

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 KZfaq when it come to this stuff. Simple, to the point, no BS.

THANK YOU!!!

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

Can inverter coolant be done with front wheels up only, or does it need to be level like for the transaxle?

Thank you for this video. It really helped!

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.

Jose, is the plug and process the same for a 2016? Great videos!

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.

Thanks for making this video. Very detailed and informative. Can you make for for the inverter coolant pump replacement?

thanks

wow the old fluid looks so clean. is it because it wasn't driven much or it is supposed to be clean?

My dealership charges $309 as Hybrid Cooling System Service, 3yrs/60k. I am going to do it myself. So easy to do.

Cool

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 !

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.

I am looking for a video on replacing the hybrid water pump for it.

Hey, thanks for the videos it helped alot. Do you have a video on a radiator support replacement?

I need to buy one of the oil catch can mounts do you have any?

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?

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.

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.

Can u make a video bout cleaning or replacing fuel injector

I had a question about the radiators in the front. I see that they're kind of split into two individual ones right behind the front bumper. Can you tell me which ones the engine radiator, AC condenser or invertor radiator?

Is the Drain Gasket and the Fill Gasket the same size?

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!

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.

Is this the same procedure as a 2014 prius plug in?

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 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...

Great Video. Do you believe the PCV valve should be changed at around 50,000 m or os this not really necessary?

Hi my prius is 2009 is it the same process ?

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

I’m not quite at 110k. About 5k short. Can I juts top off till I reach 110k ? Reading low.

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?

👍👍👍👍👍👍

Thanks for explanation! My prius 2012 has 60000 miles. Do I need change coolant ?

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...

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

What does the inverter do? Does it convert DC electricity from the hybrid motor to an AC current for the electric motor?

Great videos! Two questions- is it possible to get the inverter drain plug out with just a standard ratchet? I see yours has a curved handle and that there is some kind of support bar there that might be in the way other wise. Also, per another videos instructions I only bought two jugs of the coolant. Is it possible to just top off with the used coolant afterwards? Thanks!

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

Anyone know where the drain plug is? Is it near drivers front tire?

My car is making this noise 5:46 every 20 seconds. What do you think causes this

Great video! What are the benefits of changing the coolant? Does it go bad over time?

When you repeatedly turn on the car, was the A/C running as well?

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.

My car ran code p0c73. Any advice on the first steps to repair?

For the bolt gasket for the invertor, is it the type the oil plug has or the type the transmission plugs have?

all 3rd generation prius have same 10mm hex key drain plug for inverter coolant? or some other sizes in different variants?

What exactly is the inverter coolant for?

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?

How much coolant is required for this job? I'm here in Fairbanks Alaska and have to mix mine up 65/35 to deal with the extreme cold, and need to know how much to buy.

Thanks for this video. However I have a question, I replaced my inverter cooling pump but I still have the leak issue. looks like the air bubbles causing this. do you know how can I remove the air bubbles out of this systems? Thanks in advance

is a full drain required? Wondering if there's anything against just topping off the coolant when it looks a little low.

This is necessary before working on manifold/egr valve?? Prolly the other vid on engine coolant?

When you turn the power on to “ready” does the inverter pump work by itself or you push some buttons? Sorry, new to Prius

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.

When cycling through ready mode, is your foot on the brake pedal?

thanks for the video. But why and how often I must drain and refill? will the fluid lose its characteristics after a specific time? thanks again.

hello i have a 2010 year toyota prius and the cooling pump that I have compared to second generation of prius it seams different, 2nd generation one is boiling but mine is still so does it mean mine is damaged?

Rather than getting under the car to drain it, could you pump it out the top like you did with the brake fluid?

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

now if only I could make what dealers make doing these

What brand, what kind of fluid do you use? That is essential information!

Question: Maintenance mode? What brand coolant are you using?

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 ?

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?

Pls may I know what will happen if I use tap water instead if coolant in my prius inverter hybrid system?

Hopefully this will be the same for my 2016 Prius. Looks like KZfaq is removing Car repair videos -_-
