How to change (& bleed) the INVERTER coolant in a 2004-2009 Toyota Prius (in 20 minutes or less)

[@alexanderdishes5384]

Thanks for the great vid, just a note for ppl watching the drain plug has torque spec of 29 ft lbs.

[@cityinthesky1341]

This is the only video I have seen that shows how to bleed (burp) inverter coolant for 2nd gen Prius. Thank you!

[@anothermortician]

Super easy video to follow, thank you! FYI to anyone who runs into this issue- after refilling the coolant and turning the car on, the pump was running but there was 0 movement in the reservoir and nothing coming out of the bleed valve. After freaking out for a good minute, I ended up repeatedly sueezing the inlet hose of the water pump which helped dislodge a ton of trapped air, which then got the fluid moving.

[@gracepryor9960]

Just did this today, and I probably spent five minutes squeezing air out of that inlet hose before fluid finally went down it!

[@willrietveld4317]

I had the same problem, but squeezing the hoses to/from the pump and no luck, so far.

[@petermoylan8969]

[@ericwilliams1989ew]

I did this today while changing the inverter pump. I drained the old coolant first, then I proceed to change out the inverter pump. It created less of a mess and didn't have to clamp the hoses off. After the pump was installed I filled it with the new coolant like in your video. The small plug where you bled the line for me didn't have much air in it because I forgot to open it when It was draining . but this definitely works!. Best way to kill two bird with one stone, also taking the headlight off gives you more space to work on the inverter pump. Thank you for the video!

[@Dlroper95]

I had to go through a dozen videos to find someone that wrote out “BLEED = GET RID OF AIR BUBBLES” Thank YOU!

[@RphC74_mo]

Thanks for making this vid, very clear and made the job easy! At 245,000 miles I was long overdue. I had put it off thinking it was a difficult process. I will also add that I used a 24mm socket on the drain plug, since everything else on this car has been metric.

[@MountainSpringsAdventures]

Yes, they were sold out of the metric size plug when i went to buy it. Glad it was helpful

[@JesusRodriguez-vp9hg]

Just wanted to say thank you so much for this DIY VIDEO!! you helped me save thousands by not taking my Prius to the dealership!!! Spent less than 100 dollars!! Much love for our Toyota Prius community!! God bless!

[@markmarkell9209]

Also, the drain plug is a 24mm. 15/16 turned out to be very snug. Great video. Good detail.

[@FoodTrucksForDummies]

I just replaced my inverter coolant pump on my 08. Nice video!

[@halfpac5]

How did that job go? I live in milwaukee where all bolts and nuts are a bit crusty....

[@MountainSpringsAdventures]

Nice 👍 was it hard? I haven't done that yet

[@alanachristen699]

Awesome video, saved me having to replace my whole water pump because I just needed to burp a little bubble from the coolant that was tripping the engine check system. NOTE for other viewers: I had to use a 1/4” OUTER diameter, 0.170” inner diameter tube on my 2009 Prius. The 1/4” inner was too big for my car.

[@mytube92369]

Such a precious info man, thank you much!!! I have 415k with my 08 prius,amazing car but have heat issues I hope this will help especially now in the winter,no heat in the car.

[@HowtoRestoreHeadlights]

Inverter coolant shouldn’t have anything to do with heat inside the cab. Check heater core and possible low coolant in the radiator on the resourvoir on passenger side

[@RogerPack]

Any check engine codes?

[@justinhaller2055]

Thanks I just bought a 2007 Prius with 255,000 miles on it and I've never seen such a complicated car before.

can you make a video for doing the engine coolant? this was really good! thanks!

[@adrianbyrne3413]

Thank you for taking the time to share your informative video. In order to make your video/channel even better, can you please consider conveying measurements, volumes, lengths, diameters, capacities, engineering units etc in metric as well . The car was manufactured in Japan using the metric system and other than a few countries like the USA uses the metric or ‘the system or ‘international units’. I will be subscribing to your channel now and thank you again for your time and effort making your videos.

[@davechavez5788]

Thanks! I'm getting ready to change inverter coolant pump, and will change the fluid at the same time.

[@MountainSpringsAdventures]

Good luck!

[@KaBuKiM]

Quick question: I see you are doing the whole process, from start to finish, with the key/fob in the socket (as if just before turning the car ON). I saw multiple processes with the car that needs the fob to be far from car so it doesn't turn on various systems. Is it not the case here? ie - is it perfectly fine to do the whole process with the fob in the car? Also, thank you for a very informative and well-explained video!

[@skepticalmechanic]

That’s an old beast you have there.. inverter is HUGE!

[@peterdunn6124]

My 2006 prius decided to come up with the trianle of death. The duagnosis was inverter cooling pump fail so will drain the fluid first, replace the pump and then refill as per the very clear and logical steps in this video. Cant believe someone used green stuff. Definitly more suited to copper related systems. By the way ive recently had to bite the bullet and replace my hybrid battery after having replaced various failed cells over the past few years. Also had to replace the hybrid battery control board due to corosion caused by module leakage over time. Only done 110K km so wirth keeping until I can afford a Tesla (2nd hand) that is.

[@trapsthetics4660]

Will bleeding the fluid get rid of the triangle ?

[@robertsteadman4226]

Awesome thanks bud, needs doing after 19 years

[@daks4s]

So if that clear hose is not spitting/leaking it must be that the pump is not working?

[@hayyankhan6150]

I recently changed after market coolant which is pink,I think I will need doing this as well. Question is what was the effect on the drive. My car does not drive well on battery it just struggle 😫.

[@elmurillo82]

Question for you..@MountainSpringsAdventures While your doing the burping or bleed per say ..its in Aux mode correct?..With the hose attached leading to the reservoir.. just double checking.. (Double press the Start button W/out the brake )...

[@waheed3894]

It's perfect and easy helpful video I saw couple videos was to complicated.thanks again God bless you

[@MountainSpringsAdventures]

You are welcome 😊

[@lmc2375]

That was great, helpful. Separate matter entirely. What would you maybe know about why Ready light comes on, won't stay on? I thought it was 12V, replaced it and new neg ground wire. It did Ready on, then started acting up by turning itself off a min. or less later The hole for ground wire screw had a tiny screwdriver scraping for any residue, corrosion, not much, but that did at least make some difference. It then kept Ready light on for about 15 min., drove for a block and back, then went off again. I really hate going to dealer, they clearly rip people off. I've caught them twice in outright lies so, I now avoid them. Few others seem to know a little, but not enough. I know just one rather knowledgeable place, but they're 4 hrs. away in Bakersfield. Found them super helpful once on way back to Palm Springs. Will drive there if I have to, but figured I would make a few more inquiries to see. It is an 09', should just buy a new one. Though, one of my dogs sheds, and thought of that in a brand new car is a huge turn off. I do drive it even though Toyota said "You can't." I disconnected Neg cable and its ground wire. Ran a single cable clamp to neg post, its other end to nearby ground. It is a pain to unclamp, wait 30 sec. reclamp, but it is possible to drive. Yest. I started it that way, then removed clamp to reclamp for some reason and to my surprise all remained ON, did not go off like it usually would. I actually drove it around like that. Not sure how that was possible, but I did it anyway. Another looking at it said "You can't drive it with its single neg cable disconnected, but I showed him that I was/am. I left bc if he could not see how that I drove it just like that to him. What help is he really going to then be. I even went to 2 electrical shops, they did not know, they wanted to bolt the single cable clamp on. Why? Then I would have to unbolt to reclamp to start it? No! I do not know a lot about Prius, but I found these two guys are not thinking too far ahead, mwybe should not have them working on my car if I know a bit something more than they do on that one idea. I could end up with other problems. I have had things before so, I'm leery. Just asking what would be your thoughts as to what it could be, if you had a min to say. Thank you.

[@JWbabyshark]

When you have the hose connected to the bleeder valve, you should let it drain into an empty container NOT in the reservoir. This way if you have any old coolant in the lines it will not contaminate the fresh coolant in the reservoir.

[@OranJuno]

He said he flushed it again with distilled water before putting in the new coolant

[@destal721]

i attempted to do this today but for some reason once i get to the step where you fill the reservoir the coolant will just empty out the overflow tube do you know why it is not holding while i fill with engine off? thanks

[@destal721]

i figured out that my funnel was not long enough and when i was filling up the reservoir with coolant it was just going straight into the overflow tube

[@BenjoC8632]

Would I be able to simply add a little pink coolant to my reservoir? It’s a little low

[@marcb7231]

You can top off with Toyota Super Long Life (pink) Coolant as long as you know that's what is in there already. I'd advise against mixing and matching different brands. Not all pink coolant is the same.

[@ashlynnwilliamson3253]

Trapped air bubbles can cause issues with the inverter coolant pump you just put in. Best case scenario, the pump wouldn't function optimally. Worst case scenario, the new pump breaks and causes damage to the inverter.
