Do not be fooled by this mans cheery nature. This was a truly hellish job

The best tutorial to change this pump. Thanks to you I did it in about 1hour.

I just replaced my inverter pump on my 2008 Toyota Prius with about 154,000 miles. I went through the bumper cover & headlight method. Pretty easy and much less than $750 my dealership wanted including flushing and replenishing the coolant! In my opinion, it made sense to completely drain and replenish the coolant at the same time. Love my Prius, KZfaq and Amazon make driving and owning my Prius even more affordable!

Great job. Good camera skills. You don't waste time talking about pointless things and everything is hands on. No blurring shots. I admire the fact that you work with what you have. Example hammer for a lift and needle nose pliers to take clams off. That's exactly what I'll have to go through. Thank you for the video.

My prius has gone through two of these since I've owned it and I've watched your video each time to help me replace it. Thank you!!

May I add that the invertor water pump, that is next to that module you replaced, protects the $4,000 invertor. The invertor water pump fails every 3-5 years. It costs $70. Just buy one & keep it in the trunk. If you don't see " turbulence " in the invertor circuit coolant reservoir, STOP. Tow it to mechanic or your home. It is diy type replacement. Peace.

I have used wine corks to plug the 3 hoses! Lol. Same for when I changed the invertor water pump. Worked well, probably best to stick with the dense rubbery kind not the kind with crumbly cork material, don't want little bits falling into the hoses obviously. As you disconnect each hose place your thumb over the opening, reach into your pocket for the wine cork and plug it (thin corks fit as plugs, not thick ones). Simple remedy. Some of you manly beer drinkers need to drink more wine, ha.

I had the Code P1116 after replacing the Coolant Control Valve myself. The hoses was messed up while I installed it, but I didn't aware of my errors. This video helped me so significantly. Thanks Vlad!

Thanks. For REAL. Toyota Dealership quoted me $110 diagnostic (comes off final labor charge) & their hourly price guide for this was "maybe under $500" This part new at Autozone is $75. I hate having to work on my own car but always have. At 50-I hoped to never have to again. Thanks to your video I can see I can do this. Friggin-A. ✌

I went to Auto Zone after the signal light went on and they checked it and the code said the coolant control valve in our 2008 Prius was broken. I ordered one online. I was able to drive for a few days with no problems overheating. To begin with, I used car ramps on the front and one of those flat scooters to get under the car, chocking the car at the back with rubber blocks. No problem with the top bolt or bolts, but on advice of a local Toyota mechanic I used a smaller 1/4 ratchet with a 10 mm socket to get the bottom bolt off the bracket that holds the part to the car. It was stuck and I was afraid I would ruin it. I finally got the control valve out from the top of the engine. It was a tight squeeze. To get it out, I shimmed in a wood block to hold the inverter up after I took the two front brace bolts off the inverter. Sorry but I don't think I really needed the special hose clamps to save the coolant fluid from dripping out. After a struggle, I ended up just letting the coolant drip out into a container. I don't think you will lose more than a gallon, anyway. The real problem was getting the crummy original hose clamps off. Toyota should have just put regular ordinary screw hose clamps on these. You need to get some long-handled, long nose pliers, cheap at Harbor Freight to help with the dratted original Toyota hose clamps which took me several hours of work and a trip for longer tools and a decent ratchet to Sears and Harbor Freight. I used the long nose pliers, one that came in a set at Harbor Freight with a bent end for hose clamps I guess, and a couple of vice grips, one of them small, along the way. I am not as good as this video guy, for sure. I am wet and dirty but just put the new part in. I did buy the special clamps for the hoses to avoid losing fluid but it was a waste of money and I think the best thing to do is what this guy does. These clamps got in the way. I learned that I could actually let the coolant leak out and save it and pour it through a filter back into a container and put it back into the car later. I used a coffee filter to funnel the spilled coolant into a container. I then poured it into the radiator slowly through a funnel and allowed the bubbles to come out of the system -- I ran the car in park and it took a couple of hours for all the bubbles to come out as I watched the open radiator. I had bought a gallon of pink Asian coolant at the auto store which they told me was the same as Toyota brand and I haven't had any trouble with it for the past few months.

I put mine in from the top just like this, thanks for the video!! I do have a trick to make it even easier. Remove the drivers headlight assembly and it makes using 2 hands so much easier!! Especially for that bottom hose 👍

I've had to replace this part several times now (in different cars) and I always come back to your video. Thank you so much!!

I've been putting off this repair on our 220k mile 2006 because most videos made it look like a royal pain in the ass with draining, bleeding and filling everything while having to jumper the hybrid coolant pump. This is a way more straight forward approach and I'll be tackling this after the clock spring.

The trick with this one is that unless you clamp pinch off all the hoses first, once you take one off all your coolant is going to flow out of the valve itself (it comes in from underneath). So either accept it or pinch them all off. You need big hose pinchers, I think harbor freight has some but the little C shaped ones I got from autozone weren't enough, O'reilly's didn't seem to sell any either. Taking out the headlight is a huge help...got one at salve for like $20

I couldn't get leverage on the clamps or pulling the hoses with this method. Just way too little room. I ended up pulling the front bumper and right headlamp assembly. Note this is the same trick for replacing the inverter pump assembly. Its only a few screws and pops. Once you clear that out of the way you have far more room and can get the hoses and hose clamps off. I drained the system and replaced the coolant. Burped the system at the upper valve below the top metal (#6 hex wrench) while refilling. Works like a champ. Error codes gone.

I took the headlight out and it made it way easier

Thanks for the vid! When you put it in idle, Can you put a note on it to push the break on the last step when you push the power button? That took me a shameful amount of tries to realize...

Thank you “again”! For this video. I watched this to replace mine 3 years ago with cheap controller from Amazon ($40) it only lasted 3 years…. Lesson learned! This time I purchased one from my local toyota dealer for $130 w tax and this should last longer than my head gasket. 2007 Prius w/ 200k miles 🎉🎉🎉

First I repair the Combination Meter with your video, and now here I am on your Pump video because I'm starting to hear the constant clicking of the pump motor failing ..... what's next!!! LOL

Just changed this in Pahoa Hawaii , your accent reminds me of the islands. Thankyou for your simple video and inspiration. It was not easy but I’ll fill it tomorrow and let you know how it goes. Mahalo peace

I went by your video but still was struggling so I took the metal bracket off of the valve and it made it alot easier

Great vid/tutorial! Glad to learn about the engine idle hack and about how to remove from on top... both of these made the 2nd repair of this (same valve failed 2 yrs back) much easier!

For those who have tried it, how well did it hold up over time? This is the first video that didn't go completely over the top about purging and the effects of air in the system. Since the presence of this valve already Indicates that Toyota took a completely simple concept and jacked it up, I've been worried that the air bubble issue is legit

thanks, my check engine light just came on and throwing this code P1121. just order the part and will be doing this weekend

Just to let anyone know when want to put the car on idle the last step when you have press the power button you have to press it with the break

Took me four hours, those clamps are hard to get off and there is not enough space to easily work with. Glad that it's over. Thanks for the video, unfortunately had to go underneath the car to unclamp the bottom hose. *Shudders* ugh the bottom hose :( Glad to get it done!

Did this job in about an hour. If you got big hands, a long ratchet would be helpful

This was super helpful when my husband and I tried to replace the coolant flow valve in my 2008 Prius!

I would recommend the clamp tool... not too expensive 6:33

You make it look so easy.My mechanic is afraid to work on it ,so I may give it a try.

Thanks for posting! For an ‘easy’ job, this turned out to be a B!TCH for me! That 10mm bolt on the fender apron rounded on me! I came close to taking out a sawzall. The key was borrowing a super-short handle vise grips. Also, if you have big hands, don’t even try this job. Lastly, what u need are plugs for the hose ends - not clamps.

I couldn't do it this way. I had to remove head light. I can't afford to mess up my hands in the tight spaces.

Thanks, I'm changing mine, should I change the water pump at the same time, I do it every 90,000 miles.

Excellent! Thank you for the step by step instructions!

This was super helpful. Just wrapped up my repair. Thank you!

Hello, why do we need to put the car in idle (minute 7:00)? Great video btw!

Wow just u did very easy for us we learned well thanks for time

So helpful video for me! I have the same error code so i'm going to replace the valve as well and now I know how to do it easier. Thanks a lot!

Worked great. Thanks. Looked up a different video on how to bleed the system. Its pretty easy.

Here's my fix in Mn. at -10-15* F : remove CCV; clean ; remove gear cover; remove worm gear and plastic drive; manually turn valve so ports all align(small hole on 3-way valve goes down into hose that goes to hot coolant resevoir and the others will be full port FROM engine and TO heater pump). Crazy glue gear into place so ball cannot move; replace cover and reinstall; use big black funnel to refill what was lost while running in maintenance mode; (jack up front passenger wheell off ground to help expel air): lower jack and drive. It works good, never dealin' with that 3-way CCV again-DONE. Oh, the only light you get will obviously be a p1121 CCV but otherwise it's fine.

I'm going to have to do this soon. I really appreciate the video because it was helpful! :)

love it nice video bro keep it up the good work, i liked the end part where you get in not knowing what in it just like me..lol

Best Video for this job!! be sure to bleed system!

Did the check engine light come off?

Wonder if you have air pocket problems after repair

AWESOME thank You for the extra little tips in between! You're saving me sO much money 👏💗 APPRECIATE YOU

@here what was the symptoms. I m not sure if I have issue with it. My radiator never get hot else drive fine if my heater is on full fan on. I guess that valve has issue.

Thanks a lot for this Video! I did all you said in this video. I saved hundreds!

Great video. Did you have to go in and clear the code or did it go away by itself after replacing the pump?

Great video. Thanks you saved me a lot of money. Happy new year

Great video thanks for sharing got to change mine now

Its rare I ever see these but we had one come in today with a really bad one

Seems hard to do, in any case thanks for the tutorial.

Nice job. Thanks for video.

Hello. Do I need to disconnect the hybrid battery before doing the process,

Very grateful for your help! Thanks! I imagine the hardest part is removing and replacing the bottom hose clamp. How'd you do it?

How the F did you get that bottom hose off!?

Follow this video to a T but anyone who is watching be sure to burp the cooling system, anytime you change any part of the coolant system the Prius is extremely sensitive to air pockets since coolant runs throughout the entire car. I forgot to do it and the code P1121 came back.

Thank you for the video. It Helps a lot

Just the other day. I was with my mom and I noticed coolant was leaking by the left front wheel. I went to an oil change shop and it appears to be the issue

Thanks I did that too. But the top bolt was so rusty I end up breaking it. Now only one bold holding the valve... Is it bad?

Thanks!

If I clamp the hoses and don't loose much coolant is a flush necessary? Or can I just run the car, let the pump prime itself if I don't loose coolant. Thanks!

thanks you so much for made it look easy

ah that's what that is i was thinking it was a pump every time i shut off the car i hear it whining loud

Great video just fixed my gfs Prius

Thank you!

Was yours making sound before completely failing?

Why does this keep going out? We have changed ours 3 times in the last three years and now it's out again??? We buy Toyota brand parts and Toyota coolant.

👍

I replaced mine at a high cost last year. I still get the error periodically. What else could it mean?

My Prius is 2002, looks like this part is not the right one. Is it the same part # or diff?

Very well made video. Thank you for making it.

Thank you for the awesome video! I changed the valve and it seems working, but the dead triangle light went on couple of times when I was driving. Do you have any clue?

just finished fixing the combination meter, and i get hit with this curveball. i'm driving 2k miles to and from new mexico next week. should i fix it now, or is it only prone to completely failing in colder temperatures?

Did you have any symptoms before the error code?

How important is it to bleed the coolant after?

I know that this is an old video, but I'm guessing it's not necessary to change the coolant with this job? Did you just clamp off the hoses temporarily while you did it?

The coolant valve which this is its not the same thing as the coolant pump

Why not remove 3 nuts and remove the headlight?

Thanks for the tutorial! It looks like the hose clamps you recommended are out of stock, is there an alternative seller?

is $405 a fair labor cost for this repair?

I have Gen 2 Prius (Japanese Import) but I have NO Coolant Control Valve! How is it even possible?

What is this part name? Please let me know.

Great video….is this also referred to as the coolant bypass valve?

Did your car experience any symptoms before the code went off? My Prius heat is not working correctly at the moment... It works sometimes and its really hot and then sometimes, even at highway speeds, it'll just output cold air even after an hour of driving. I'm thinking some valve is stuck and this may be it? No code so I can't confirm.

Great job except tell us how many miles you had

I HAD SAME ERROR, BUT I CHENGED BUT VALVE BUT A PUMP - AND IT WAS A PROBLEM. NOT A VALVE.

So I saw another video where the coolant leaked out so they had to "burp" the system to make sure there was no air in the system. Something to keep in mind.

So it has two pumps... Just replaced one lol.. gotta replace this one now

7:50 rumble in background.....next video, how to replace the ABS actuator pump........

I have an 05prius with 121000miles, I have a new 12v battery. The death triangle shows up on the dashboard and the new battery doesn't hold a charge. Please any idea what's wrong, thank you

What scan tool did you to read the codes on 2006 Prius

Do I have to disconnect the battery?

Hi, will the triangle and engine light reset automatically? If not how do you reset? Thx

that's under recall you should have Toyota fix it for free bro>

راءع

What does this part do anyways? What happens if it dies completely? What would not work? I think mine is shot, here is video of the sound it makes: kzfaq.info/get/bejne/m6-FodZz0MeUl5s.html

I completed the install but occasionally get a temp warning. I think I have a lot of air in the lines. I tried the bleeder. I also don't see a good flow in the tanks. Any thoughts? Thx
