How to replace your Toyota Hybrid Inverter and Engine coolant

[@TheCarCareNut]

The engine coolant information doesn’t apply to hybrids with the 3.5 2GR engine and hybrids with the dynamic force engine.

[@bholahakshaye2627]

Great video as always AMD. I have a question. The premixed coolant isn't available in my country. We have the concentrated one, which we have to mix with water in a 1:1 ratio. I wanted to know if I can mix the coolant with deionized water (used for car betteries) as distilled water is really expensive here. Thank you.

[@TheCarCareNut]

Hi! Honestly I’d rather you leave the coolant alone than not use distilled water. It’s expensive but the components you are replacing the coolant for is even more expensive

[@bholahakshaye2627]

@@TheCarCareNut Noted. Thanks a lot for the advice!

[@MS-ql8xl]

Thanks for the video! Great information.. since this doesn’t apply to which I assume 2018+ camry hybrids. Would we be able to vacuum fill a camry hybrid and be good to go? Also this question is off topic but while watching your other video about the new engine with vvt-e.. when or if ever the electric motor fails would it be a diy job? Just plug and play or it would have to be calibrated?

[@TheCarCareNut]

Hi! Vacuum filling the coolant on that engine might be an issue because of the closed valves. I would still bleed afterwards. And the motor for the variable valve timing on the A25A needs calibration after it’s installed

[@thedavidlynch]

Man I do not miss living in Wisconsin for this very reason, HOLY SALT!! My goodness, I remember so many of my first vehicles were rusted so badly; brakes failing from rusted lines, suspension shot, you name it. Not to mention when I went to replace a wheel bearing, I had to replace every single suspension part I had to remove because I destroyed them trying to remove them. You're doing the lords work, cheers!

Hello, I have a question, when do you know that is time to change your antifreeze/coolant? I just bought a used 2010 hybrid Prius but i don’t know how to recognize if I have to change it already :(

[@chrismasters4951]

@@igorrosales1799 I’d ask the previous owner of the coolant was ever changed and when they changed it. If not, it’s not going to hurt anything to put new coolant in your hybrid. Better to be safe than sorry because major repairs to hybrids are expensive. Relatively speaking, coolant is cheap, a new motor or hybrid system is expensive.

When I asked at the dealership, they all agreed that 160,000 km is the time. My car has 162,000 km.

Maintenance mode: power button once (no brake), gas pedal floor twice, hold brake and go to neutral, gas pedal to floor twice, hold brake and put it in park, gas twice again, hold brake and turn the car on. Before you start turn off the heater completely. Bleed the car with the heater off. Make sure the garage is open because there will be fumes

[@sayedmohammadkhatimi6389]

Great explanation!

[@andrewziem370]

[@ThinhNguyen-en1yh]

Why do we bleed this with heater off vs on

[@claude77573]

To get into Maintenace mode on my 2017 Prius, I first had to turn the engine ignition on without starting the car. To do that, I have to press the power button TWICE without pressing the brake. Pressing once only turned on the accessories circuits without turning on the ignition.

[@claude77573]

According to Toyota Techinfo, otherwise known as the Toyota Technical Information System (TIS), for my 2017 Prius, the factory procedure for bleeding the engine coolant is to (1) turn the AC off, (2) set the heater for MAXIMUM heat, (3) set the blower speed to the lowest setting.

I just had my Inverter Coolant, My Engine Coolant and my CVT Tranmission Fluid changed at my Toyota Dealer at 70,000 miles on my Wife's 2014 Prius.It cost me $625 with tax for this service. I was able to watch the Technician perform these services from the open garage door. I did not observe him doing the Purge step as I have problems with standing for long periods because of my knees and back. The Drain and fill portains of all of these procedures are very simple. The key to this whole thing is getting the Car up off of the ground far enough so you can work on it comfortably. Several years ago I changed the CVT Transmission Fluid on my 2008 Prius it was a very simple process because the CVT Transmission has no pressure on it, it also has no Filter on it so it just drains easily. I can no longer do this work as I cannot get down on the Garage floor on my back because of my knee and back problems. I used to do about 80% of the work in my 2008 Prius myself when I was healthy. I had my own Maintenance Manual for my Xar which covered everything. I have owned Priuses from Gen 1 thru 4 they are excellent Cars. The 2008 had 197,000 miles when I traded it in and it was in excellent shape. I only traded it because the Dealership beleive it or not made me a deal that I could not resist. In conclusion I will also say this the Gentleman that makes these Videos is the Absolute Best Toyota Technician that I have ever seen and I have dealt with a lot of them since 2003.

[@rodcros]

Thank you for this informative video. I picked up two jugs of super long life coolant at my local Lexus dealership and ran my 2014 es300h up on the hoist. The 10 mm hex plug in the transmission required a leap of faith and a firm twist to loosen, but as promised, it bubbled out the pink coolant, so all was well. If I had turned a plug that hard in my Cayenne, it would have stripped, but this is a Toyota product. I reached up with a beverage tube to fit over the tap under the radiator, so I could just watch as a clear plastic jug filled, so the combined operations were pretty much drain and pour. My wife started the car while I waited to add coolant to the inverter reservoir, but it took little. Total yield of used coolant: half a jug from the inverter and a full jug from the radiator. The rad fluid seemed much more worn than the inverter fluid. I'll check the reservoirs after a drive, but there's a lot of snow this morning. Rod

@@ScottHancock I filled the radiator 1st then filled up to the line on the reservoir. At that point I ran it and kept an eye 👁 on the level. If there isn’t any antifreeze in the system.

I just replaced the inverter coolant on my 2006 Highlander Hybrid with 3MZ-FE engine. On this model I removed the front plastic grill to make it easier for my hand to turn the upper and lower inverter radiator stopcocks. The inverter radiator is in front of the main radiator. Crack open the inverter radiator cap and open the lower stopcock to drain the inverter radiator and then open the 10mm inverter drain plug under the car to drain the rest of the coolant. About 0.6 gallons drained out for me. Once fully drained, close the lower stopcock, open the upper stopcock to bleed the air, and refill from the inverter reservoir. Close the upper stopcock when coolant comes out and continue filling the inverter reservoir. You will add the same amount of Super Long Life coolant as you drained, about 0.6 gallons.

Thank you for posting your videos. Using a coolant test strip I found my coolant was still good for temperature control but needed changing due to corrosive content. I changed the coolant of my 2017 Avalon Hybrid after watching your video and seeing how simple this was vs the $250 quoted by the repair shop and dealer. You are right it can get a little messy but manageable. The instruction on switching to maintenance mode was especially helpful. A couple of comments: I would note that for my Avalon you need to press the start button 2x. I discovered this because you cannot shift out of park if you only press it once. My second comment is that because you were working on the Prius, you did not mention draining the overflow tank of the radiator of my Avalon. Only problem I had was waiting for the fan to kick on 2x - I thought I would hear them turn on. I guess my music was too loud and I had a lot of coolant overflow from the radiator when it heated up. I am glad I found your channel and it feels good to support a LOCAL channel. I also appreciate your info on how a hybrid works - very informative.

Is the engine coolant fully drained from the engine block by only using the radiator drain or is there a plug in the engine block as well, thanks

[@TheCarCareNut]

Most engines will have a block drain however Toyota almost always put it in a very difficult place to drain and what you drain is a small amount so it really doesn’t justify the pain of getting to the block drain. And when I do drain the block and take the engine apart there’s still a good amount of coolant still left in the engine. You’ll never get every last drop of coolant out of the engine. You replace enough that the new fresh coolant quantity is much greater than the old.

Excellent Video! I have a 2010 Prius with 188K miles. I want to do the coolant exchange by myself, but I have a question. What coolant do you recommend if I don't want to use the Toyota coolant?

[@jalex19100]

Thanks for the reassurance! Will take a look underneath. A friend (he and I have an Avalon hybrid) said “I spoke with a hybrid trained mechanic today. He said to change either coolant requires special tooling. Solenoids to the tranny, heater core, etc can only be opened by the tooling. He also said this machine uses a vacuum to draw out all the old fluid and suck in all the new. He said it's hard to bleed out all the pockets without the use of the vacuum.” I knew it was all B.S. Toyotas have always had a more basic, although possibly more time consuming way to do about anything.

I just followed your directions step by step on my lexus ct200h, it was easy. I am very grateful, thank you for such a great video. .

That's useful to know. There is one of them in the family which will soon need this job.

[@blacktreewall9039]

Thank you so very much. Just after finishing the procedure, I see my temp gauge in my Lexus gs300h 2014, shows a tad higher temp value after driving for 20 mins or so. Is this normal? Thanks you 😊

[@emmanuelmeyermeyer1083]

Love the videos. No one else on KZbin explains it and ads the detail you give your viewers. I went to your store to buy the bleed funnel and I see 3 listed. I don't know which one to buy. I have a 2010 Lexus 450h. The one says it's for radiators only. I only have a coolant tank. No radiator cap. Thanks for any help.

[@TheCarCareNut]

Hi! You can get either of them. Without any adapters they will sit on the coolant tank.

[@dabernathy15000]

@@TheCarCareNut thanks for this video. MUCH appreciated! Two quick questions; why would I flush vs just change fluid? Also, I'm at 115k on my 2013 450h and haven't changed fluids for inverter or radiator. Since I'm going to change now, even though the manual says the radiator should be changed at 100k and inverter at 150k, why not just do both? Thanks!

[@TheCarCareNut]

Hi! Flushes are not recommended unless there’s contamination. And I would replace the coolant for the inverter

[@dabernathy15000]

@@TheCarCareNut thank you!

[@Btu555]

do you recommend using radiator flush cleaner with distilled water and drive it couple days to clean the system?

[@howwhy650]

Thanks. Seen many of your Toyota maintenance videos and you saved me lots of time and $!! I'll reiterate other's mentioning to wear eye protection, want you safe and making more excellent videos.

Hi there, thank you for the great video. I have already completed the inverter coolant before watiching this video on my 2nd generation prius. I saw a lot of videos that talked about opening the bleeder valve for the filling of the engine coolant since it was tough to fill it up with the same amount that comes out. i did not want to turn the car on even with the maintenance mode without filling enough coolant in there. Please advise if this concern is valid. It does not sound like you have any troubles filling up the coolant though to the same amount that come out.

[@TheCarCareNut]

Hi! On the 2nd generation it takes a bit longer and you just need to turn the key on to get the pump going. So just press the start button twice without pressing the brake pedal and the pump will start going and you can continue to top it up and it stops then go into maintenance mode and let it push the rest of the air out

[@ryanwill1147]

Hello! First of all, your video was of immense help. Truly appreciate it! So here is my issue: I also replaced the water pump and thermostat while doing the coolant replacement. Used Toyota parts and they were very easy to replace. Followed your procedure for bleeding using maintenance mode and even after 50 minutes, my radiator fans never came on. The fluid levels in the reservoir did drop a bit and had to be topped off, I saw bubbles and circulation, and yet no fans ever came on. I had an OBD reader checking the temperature and it never got above 201°F. I also tried another video’s suggestion of turning the heater on to HI and still nothing. I have not taken the car for a test drive yet but will soon. Hopefully it still bled properly even without the fans coming on. Also, just to be sure, I turned the AC on to force the fans to turn on and they did without issue. Thank you so much in advance!

[@igorrosales1799]

Hello, I have a question, when do you know that is time to change your antifreeze/coolant? I just bought a used 2010 hybrid Prius but i don’t know how to recognize if I have to change it already :(

[@gloryshine1660]

Prius prime 2017. It looks like the drain plugs (yellow) are one above the other on the left side viewing from under the car. Can you confirm this is correct? It looks like it is but just want to make sure first. Thank you so much for your time and for creating such helpful videos!

[@briancwir1036]

I have a 2022 Sienna. Could you do a video showing how to change both coolants on that model please? My main concern is the transmission oil plug verses the inverter plug, and do I have to do a bleed anywhere? Thanks.

[@nickloughrey9841]

Why dont you use the vacuum rig coolant method ?for the main engine ? Have you a reason why not . I have used it on a few toyotas /lexus .......... it works great

I love your videos, all are very informative and helpful to those who wants to do their own maintenance. I just have question, my car is a 2009 Toyota Camry hybrid and the inverter coolant is leaking. It seems it leaks on the gasket and the drain plug. My question is what is the part number of the gasket and the drain plug? Thank you.

Perfect, I have a 2010 Prius and was just getting ready to do this. I also want to change the transmission fluid. I went to the dealer to get washers for the fill and drain plugs. The parts guy stated "There is no drain plug for the transmission". I said there has to be, so I asked him to just give me two washers for the fill plug because they are probably the same size. I can find very little info on the transmission service. Great videos, thanks so much for all your hard work and information. I will use your affiliate links.

[@TheCarCareNut]

Hi! Thank you for watching my video. A comprehensive video on Toyota hybrid transmission fluid replacement is coming out next week. And the washer for the inverter drain in this video is the same part no. For the transmission drain and fill plugs

Great Video man! Don't forget your eye protection under the car minimally! Excellent video!

Great video. The bleeding has been a concern of mine.

[@quail209]

I'm curious why you said to turn the heater off while in maintenance mode? I know there is coolant trapped in the heater core, is that because we want to avoid accessing it?

[@roberttadena]

I’ve seen this video a few times already in preparation for my first coolant change on my 2022 corolla hybrid le. My engine coolant reservoir have two caps. Do both caps off and to fill which one to fill from? The main cap does not go directly to the reservoir unlike the inverter coolant which only have one cap same as in your video. Will I be looking at two drain holes for the inverter coolant? Thanks!

[@riceburner4747]

HI AMD! I'm just reviewing some of your old videos. Could u tell me why Toyota fills coolant/brake fluid in the middle/in between empty & full & not top off at full? What should WE be doing???🤔 U rock!

Thanks Brother. Everything went exactly as described ( except I had to press the start button twice). God bless you and yours!
