In this video I will show you the procedure to replace your Toyota and Lexus hybrid inverter coolant. And since it's the same coolant with the same interval, I also included the engine coolant as well.
This procedure is very simple and very DIY friendly. Follow the steps in this video and you will successfully save yourself a lot of money in servicing your Toyota hybrid and making it last a long time!
Neglecting your inverter coolant could cause inverter case leaks or worse transmission coolant leaks (in models equipped). I have seen these cases through my over a decade of experience as a Toyota master diagnostic technician currently working in a Toyota dealership.
Tools needed:
10mm socket to remove shields and covers
10mm HEX socket if your hybrid has a transmission drain.
fluid catch can.
flat heat screw driver to remove clips for the covers.
Spill free coolant funnel
small coolant funnel for the inverter reservoir
Jack and jack stands.

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

[@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 :(

[@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.

[@rodcros]

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

[@coltonlapp4193]

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]

Whoever came up with this knew the Konami code

[@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.

[@KHIJAPAN]

Man I can't thank you enough for this video!! I was looking for how to do the hybrid system. A Lexus mechanic told me in the early days not to attempt to do so because is dangerous. I am a motorbike tuner but I never worked on Lexus hybrid. I learned a lot from you! Thanks 😊

[@Tsaki1425]

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. I wish you, your channel and garage the best of luck. Thank you.

[@hondoman454]

Those fans are hard to hear on the Prius as well. I thought they turned on a couple times in the half hour in maintenance mode. I'll just keep an eye on the coolant levels initially. Cheers!

[@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

[@alex15a30]

Good to know I am not alone. I was fighting this %$#*&%#*!! inverter coolant drain plug on my 2014 Lexus ES300h today and lost. Tried a breaker bar with a 2 ft pipe extension, electric impract wrench and a compressed air impact wrench. This thing just does not bulge! I broke my 10mm hex socket in the end. Sprayed everything with WD40 and PB Blaster and will try again with a new socket. Steel + aluminum + rust belt salt just don't make for a good mix.

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.

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.

Very informative video. I am curious. Why do you not turn the heat on so coolant can run through the heater core after refill?

Very nice and clear explanation.

I’m really glad Toyota made self bleeding while the caps are off, not that older model bleeding were hard. It was just extra, and coolant mess with bleeding.
