2010-2015 Toyota Prius Engine coolant drain and refill
HTML-код
- Опубликовано: 8 фев 2016
- This is a 2012 Toyota Prius. We are doing a engine coolant drain and refill. We didn't use Techstream so we had to put the vehicle into Maintenance mode so that the vehicle can idle without the hybrid system interfering. Make sure not to drive the vehicle while in Maintenance mode, or else you can damage the vehicle. After the vehicle radiator fan kicks on, you want to turn on the heater to high so that the coolant can cycle through the heater core. After that, you are finish. You want to do this maintenance every 120k-150k miles.
Also note, some models don't have a coolant bleeder valve, such as my 2012 Prius. I believe later year model has them, you can use that to bleed extra coolant out but its not necessary. Top coolant off to the B line
Tools:

Maintenance mode: power button twice, gas fully twice, brake once (hold), neutral, twice gas, park, twice more gas pedal
How to turn off this mode ?
@@Doinformowany Turn engine off with start button and it will revert back to normal
Nice cheat code
up, up, down, down, left, right, left, right, B, A and Start
Will this give my engine infinite lives or any special powers?
Super helpful.
Anyone else think the Maintenance Mode process feels like a video game cheat code?
Thought my Prius was going to start floating or something
🤣🤣 up up down down left right left right A, B, Start
This channel is such a hidden gem! 💎 Thank you for sharing your expertise in such a beginner-friendly way!
Great video and instructions for engine coolant and inverter coolant replacement. Based on dealer quote, this saved me $550.
I was about to take it to them i will do it myself 😂
Man that was way easy to change out the fluid. Great Video sir, keep it up.
Thanks!
Using a trim removal tool, gently wiggle out the plastic pins that hold the splash shield so you don’t break them. Reinstall them in same location. Have spare plastic pins ready. You want that shield just like it came from the factory.
Thank you for the video, it helped me so much to do the coolant change and to do the whole process again when I had to replace the water pump. Maybe next time you can add the video about that too, even though is actually not bad to do. Only 2 hours tops.
for sure when ours go bad, its electric water pump, so it shouldn't go out on you...
Thanks for helping me diagnose this. I’m headed Valvoline but I didn’t know where to turn before. Thanks.
Thank you for your video i use this videos for change the spark plugs, transmission oil and the water pump and coolant
thx man. I just bought a hybrid prius and didn't know how to work these new cars. thx for the help and I'll share this with everyone I know
thank you, we appreciate that :) You can also check out PriusChat forum as well, they are pretty helpful in questions in case you have any problems with your vehicle. :)
thx will do
helpful video for "maintenance mode."
i'm going thru changing the water pump and thermostat now. if someone doesn't want to remember all those steps for maintenance mode you can just place an item on the accelerator pedal and the car will start and stay running. if you want or need to get to 2500-2700 rpm you can place an item heavy enough to get the pedal to get to those rpm's. bleeding air out of this car was more of a challenge then i thought it would be. had to compress the inlet hose(at the t/stat) many times to prime the pump. good video. thanks.
My 2014 prius almost at 120,000, and I'm planning to replace the water pump on the enging. Should I replace the thormostat as well? Have you ever had to replace them on your car?
Put a piece of vinyl tubing on the radiator drain petcock, and run it into a jug/container. No splashing!
how does it good to inspection mode do I wait
Great Prius maintenance video!
Absolutely what I needed, thanks 🙏
How long should it take for the fan/thermostat to kick in?
How long should I let it run with the heater on?
What is wrong if the fan never turns on? Been having overheating issues. Sensor?
Prius 2014: my engine coolant is at the “low” mark and the inverter coolant is a little over the “F” line. Is this “ok”? (When to the Toyota dealer/side job with mechanic). The measurements are with the car cold, sat over night. Southern California climate of that makes a difference.
Should I just add a little distilled water?
Thanks
You put the cap back on before running the heater? Wouldn't that keep more air bubbles from coming out?
My thoughts exactly
@@mattgreen4611 I think the coolant runs through the heater core whether you have the heater on or off. It's like a little radiator inside the duct work or heat and air assembly.
How about air bleeding the system?
Thank you for this video. It really helped!
Excellent video. The explanation was very good !!
Is there not, an engine block drain plug, also? All the coolant you are getting, is out of the radiator bottom?
First I want to thank you for this awesome video. My 2010 wouldn't pick up. Then I found your video. Now my car picks up, runs in the maintenance mode but for a few seconds and then shut back off. Please what else can I try? Thanks in advance.
Thank you so much for those information sir that gain our knowledge thanks and awesome
If i have a Techstream what i need to do after refill ?
I now know the cheat code to my car. Thank you.
Thank you for the video. I took engine radiator out, but do not what screws/clips go where. Do you have any video or a diagram you can refer me to on the internet. Thanks !
Man, you and this video are pure life savers. This is exactly what I needed. Thank you very much. New subscriber
Glad it helped 👍🏼
@@NutzAboutBolts how long does it take for the fan to come on. it's around 50 degrees outside where I am
@@Juss-Saiyan if you idle it, it’s usually longer than 30 mins. If you keep it at 2k rpm, it’ll probably turn on between 15 mins to 25mins.
@@NutzAboutBolts the fans started kicking on and off so I guess it worked. I have hot air, but what's strange is I'm use to seeing a lot more movement in the water when it kicks on. Also weirdly enough I had it at exactly full and now it's like an inch over full..? That's a first as well
At what temperature does the thermostat open? Shouldn't there be a noticeable drop in coolant level when it does? I'm bleeding mine after replacing my water pump and refilling coolant and temps got up to 215 Fahrenheit without any drop in coolant level.
Did you also replace the thermostat?
I have a great question for you. I have a 2014 toyota prius v and I have low heat after driving for 10-15 mins. I changed the thermostat and that only made a slight difference. I make sure my coolant level is to the top. Maybe is obvious but I do have a bad head gasket that doesn't mix with oil just burn coolant and the heat was working even with that issue present. I put the car into maintenance mode and left the car on reving to 2000 rpm for about 40 mins with the tank cap off and the heat on high and the car never gets hot even in full speed and max temp. I also squeeze the lines awhile it was on with the tank cap off. I changed the cap and still no heat. When the cooling fans kick in the hoses from the thermostat is hot and I measure the temperature of the two heater core hoses and they were the same temp 102c. I also flush the heater core before this and made no difference. After all of this is it possible there is still air in the cooling system? Is it may be that three way coolant valve that is causing the issue even tho I don't have the p0 code for it?
So to summarize when you want heat the car isn't blowing hot air? Does your car still blow cold air when you have the AC on? If yes then most likely the heater core is clogged up and if a flush didn't work it the core will need to be replaced. If the cold air isn't working either most likely the blower motor is out. A heater issue has nothing to do with the head gasket and the obd 2 system so you'll never get a code for it not working.
@@MrTmenzo Just a update in the matter. The AC system in the car isn't usable since the ac compressor was causing a high voltage leak which will turn on a hybrid code light so i just disconnected the compressor from the car, its still there and the lines but no com with the compressor since i disconnected from the wiring harness. It blows cold air when i have the heat on and after 20 minutes of driving it would get Luke warm but not warm. I found out that if leave the car in maintenance mode for 20 minutes than i get good heat. Don't worry i am not driving it with maintenance mode on because that will ruin the transaxle but if I wanted to take a nap that's what i did since i know i am not going to be driving it. Both the heater hoses are hot and i did flush it but honesty I don't think that its clogged since i eventually got great heat after being left in maintenance mode for a long time. Before that i replaced the thermostat twice and both times i found it closed which is the way it supposed to be because if I found it open that would be the cause of my problem. Most of the time having head gasket issues wouldn't effect the heat on cars but i found for some reason if you have a head gasket issue on a prius it will allow a lot of air to be mixed with the coolant so you would never get the heat you want. By leaving the car in maintenance mode or driving the car nonstop for 70 or more miles without a break any air that gets in the coolant would bleed out because of the temperature of the coolant would be so hot and the engine will stay on which would mean that the hoses and all will cause any repeated air coming in will just bleed out. I still have the prius now but i already have a 2000 lincoln continental with 105k in good shape so i am just waiting until i have the money for the registration and take it to a shop to get the inspection done. It's been a good run with the prius, i got it at 320,000 miles from a mechanic that my dad was great friends with but both him and my dad died of co-vid 19 not so long after. Right now it have 372,000 + with it misfiring from here to there and burning crazy amounts of oil even after replacing the pcv valve. I just put a heavier oil for more protection and that it last longer and i get a big hit on the mpg for that but for me it's better for the car to run with 21 mpg rather than having to check it everyday for oil and having 50 mpg but one day i forgot to check and the engine throws a rod. Thanks for trying to help out but unfortunately having a head gasket issue is a death sentence for the heat. After i tried everything i came to the conclusion and many people on the prius forums have come to that conclusion after all the crazy things they have tried to get their heat to work.
Tha kool for video . I have a 2017 Prius two. I’ve driven 35k mikes . When should I change my coolant liquid?
Dealer says Toyota coolant good for 100k it's long life coolant, but good idea to do it at 80k
You don’t turn the heater on when you are on the maintenance mode?
There's a vent valve on the heater return pipe on the transmission side of the engine,open that to get the air out quicker
It’s only on 2010-2011 models
Will it work on the Camry hybrid?
Good info! Thanks. My 3rd gen Prius has no heat.🙁 coolant level is about 1/4” below the low marker. Car had been driven about an hour earlier. What to do?🤔
Did you follow the procedure? Why’s it below the low mark?
Thanks for sharing. Did it exactly following your procedures but in the last step to put the engine in service mode did not see much coolant going down the funnel. The fan just won't come on since it's freezing code today when I did it. Any thoughts on if I need to do anything else to bleed air out? Thanks!
+Yi Ni like we said in the video, when you're in maintenance mode, you're not suppose to be driving since all of the system is off or disable. Just run the engine until the radiator fan comes on. Check the overflow hose that goes to the reservoir until its hot as well. Eventually your radiator fan will come on, you can notice that our coolant starts bubbling because the system is hot and a couple minutes later, the fan will come on.
@@NutzAboutBolts how do you put into maintenance mode? Another reader explained how to get out of it by shutting the engine off.
@@harsep we showed that step in the beginning of the video
At 316 they go thru steps for maintenance mode. Then turning on ready mode (idling) to cycle cooling system.
If you turn your heater on "full blast" the gasoline engine will keep running until the engine warms up and cooling fans energize and the heating t-stat opens up. I don't think there's any need for the elaborate "maintenance mode" ordeal.
you can also get dr.prius mobile app and use the free tool to go into service mode.
That's I'm thinking
Hi, Thanks for the nice video. I have 2014 Prius V (3,30,000 KM). It keeps on blowing cold air in the morning when it is cold outside even after the coolant temp is 85C. Also electric water pump stays at 6375 rpm. However if I restart the engine then pump runs at 2975 rpm and it blows hot air with no problem afterwards. Recently I got the error code P148F (Engine coolant pump over revolution) which I cleared. I have already replaced the thermostat but I think the old one was also good. Please advice if I need to replace the water pump? I appreciate your help. Thank you!
There’s a Facebook group called Prius Nation, I think someone was asking something similar to coolant, you can join and ask them. they should be able to help you with your answer
Hello, great video! I have a question regarding the water pump, how many miles can you recommend to replace it? I have 170k miles
I know it’s easy job but some people saids that if you get the light alert maybe it’s to late!
Thanks in advance
Mines still running at 240k miles. I’d change it when it alerts me lol
mines is still running at 392K, but I did replace my first pump around 28k something was wrong with the oem water pump. I did replaced it with another OEM pump. I was looking at this video, on how to bleed the coolant, since I just cleaned out the EGR and EGR cooler. How ever my fan is not turning on, might need to run it till 20min.
does the method of getting into maintenance mode apply to Lexus CT200H as well? (same 1.8L engine)
To anyone else reading this now, the answer is yes
@@hiwrenhere thank you, a bit late (3 yrs old) , but I guess it beats never
Thank you very much. So well done!
Hi, how long does it take until the cooling fans turn on during maintenance mode?
45 mins of you leave it idle, but if you rev it up like we do to about 2-3k rpm, then it takes around 15-20 mins.
@@NutzAboutBolts 3
The fans kick on when the coolant temperature reaches 95°C, so if you have an OBD app or some other means of checking the temperature, you can watch your progress instead of just waiting.
@@bearsneaglesentertainment3901 what would cause it to get up to like 215 in maintenance mode while doing this process. It kept climbing up higher so I shut it off, but I’ve got new pump and thermostat no leaks fans came on just didn’t help to drop the temp
There are access holes for both the drain nozzle and the tap. No need to take anything off underneath.
We were filming the inverter coolant drain and refill video as well, so that’s why the undercarriage panel was off. But yes, you don’t need to remove the panel since there is a hole for the radiator peck cock from the buttom.
hi nice video thanks for help I m having issue with hot air it's not coming out of vent and it's engine getting hot as well from the time I have changed radiotor looks like air blocked what should I do
whats the history of the vehicle? suddenly it just doesn't blow hot air?
khurram manzoor shahid might be thermostat.
How much coolant did you use?
Appreciate your awesome videos, NAB! Ever done a Gen 3 prius thermostat replacement? I heard it's just 3 nuts where 2 is easy and the 3rd one is hidden in the back (hard to get to). The hard to get to last nut.... is that a nut or is it a bolt? What socket to remove last 'hard to get to one' . Thank you
The hidden third one is a bolt and you can take it with 10 mm

@@kumara5492 Appreciation, brother
VERY INFORMATIVE THANK YOU
You're talented
Спасибо.
thank you easy done with your help.
Hi nuts about bolts, does the Prius have a coolant temperature sensor do you have video on how to replace it? (if it does) And is this maintenance the same for the 2014 Prius plug-in model?
Marcos Cisneros yes, it does, it’s connected with a 2 wire connector between 2 coolant lines I believe, I haven’t look for it myself. And the maintenance should be the same with the plug in
Great video per usual.
+Mr. Buttermaker thanks
Wonderful video as usual @NutzAboutBolts2 , one question, does that means it is flushed? or do I need to use the flush with flush fluid?
I think flushing involves draining the fluid, and then adding distilled water, and then dumping that, maybe repeating a few times. This will get absolutely all the old coolant out of the system. If you just drain a little bit may be left. After you add all the distilled water and drain the system empty again you can close the valve and add the new coolant. I think this process is recommeded if you put the wrong coolant in or had really old bad coolant that you want to make sure is out of your car.
@@devoidbmx1 thank you! I sold it
Pls may I know what will happen if I use tap water instead if coolant in my prius inverter hybrid system?
Pure water will boil or freeze far easier than coolant. New Coolant acts like a lubricant in the cooling system as well. Old coolant over 150000 miles breaks down into heat and friction causing salts. Only use water in emergencies. You could probably get away with water only as coolant if it never drops below 32 degrees and you never turn the air conditioning on. Still, a water cooled engine will overheat the hybrid system, turning it off... And then you only get 30 MPG instead of 50...
How much coolant should I buy if I'm going to do the inverter and the engine at the same time?
2 gallons.
Thanks!
When you start draining the radiator, I note that the outlet might be able to put a bit of hose on it to direct the flow (you even complained about a splash in the video).
Any idea what size (ID) hose that would be?
Faded or loaded off the Ron
Would this procedure apply to a 2014 Prius C? Would there be much difference in steps?
I dont believe so since those models range from 2010 to 2015 its practically the same thru those model yrs!
exactly where is the drain had a hard time seeing it is it on the driver side or passenger side or dead center does the whole plastic need to come completely off
on the driver side under neath the radiator.
great videos man. quick and easy and great quality!
+Jesse Ramirez thanks!
I just bought a 2010 Prius with 130k miles on it. (Hopefully it will last 200k). How can I tell if the coolant is old and therefore, needing replacement.
you'll need a antifreeze hydrometer to test the concentration of the coolant to know if it needs changing or not. If it hasn't been changed, we recommend it at 120k miles.
Question, theres a plug right next to the engine coolant reservoir that has a black plug on it. My prius is leaking coolant from that plug, i took it off and noticed that the bottom of that plug it has a gap, is that how it supposed to be or mine just craked because that is where the coolant is coming from.
Luis Carrillo, is it a small black rubber cap, on reservoir tank??
I was getting ready to drain the coolant and I noticed that the reservoir is slightly below the low Mark in my car and in your video. Is some coolant loss normal at 100k miles?
That’s your head gasket failing. Clean the egr pipe and cooler
Its normal . it says in your book to a dd engine colllant at 100thk miles
Thanks again for the great videos!!!!
np :)
@@NutzAboutBolts hey is this the same coolant you use for the inverter coolant change and what is it called exactly the coolant ?
Thanks for this great video.
I followed all the steps except keeping the engine running in maintenance mode until fan comes up.
It was fine in city driving but after like 10k kilometers I had to travel on highway, where while driving on constant high speed of like 110km/h for like a minute or so temperature warning light came up, and now it comes up on highways on above or higher speeds and the light goes off when I remove my foot from the pedal.
I got the coolant from a Toyota dealership in town but he gave me Toyota pre diluted long life coolant, it was in red color not pink like yours and made in Thailand.
My question is wether the above problem is because of (a) faulty coolant; (b) not removing possible air (though I did run my engine on maintenance mood but not long enough for fan to come up), or (c) my water pump not in perfect shape (and how to check water pump's performance).
Its possible that you didn't bleed the air in the system. I would recommend redoing the procedure, and use the 50/50 pink coolant. The red coolant is a different additive for older Toyota vehicles. You need the 50/50 pink coolant and redo this procedure and make sure to wait for the radiator fan to come on. Good luck.

Haseeb Ahmed did you find out what it was
Did you figure out what was wrong with it? I'm having similar issues, thanks!
What's up Haseeb...??? Did you ever get to the bottom of this ???
I have a 2015 Prius and it looks like there is a 2nd coolant reservoir on the drivers side. It’s pink in color as well. What is that!?
It is for the converter only, not the engine, although it takes the same type of antifreeze
So my coolant was bubbling up for 20 minutes or more and then when it slow down just a little bit I turned on the heater to let all the air out and it was still bubbling up a little bit and I close the cap while the coolant was still hot and turned off the vehicle am I going to be OK?
yeah it is fine, its bubbling because the engine was hot, ours did the same thing.
Good
Hi, what you should do if at the end the heating is low because there is air? Thank you.
Bleed the system by draining the coolant and then refill and run the engine till radiator fan turns on
Hello! Thanks for the video. I have a prius 05 and change my first time coolant system. After done, I noticed a water flowing from the passenger cabin I don't know why. Could you please explain to me how to fix it? I really appreciate from your time.
Sovann HEAN it’s possible it could be from the AC drainage hose...
@@NutzAboutBolts I have checked there is no leak on the floor mat. But it just a sound of water movement that I noticed. Is it cause by AC?
Sovann HEAN that’s probably the coolant flowing through the evaporator behind the passenger dashboard. You’re fine.
@@NutzAboutBolts Thank you so much!
i just bought a 2010 prius second gen. with 106k should i change the cooling? previous owner told me they never did.
Yes change it
What is inspection mode?
Thank you for the helpful video!
You’re welcome
Could i use a hand pump to suck out the coolant from reservoir so i dont have to take off the under pumper?
Let gravity do the job, it’s easier, and hand pump won’t suck everything out of the engine block...
I find that just run the heat on HI will make the engine run. you can also hit the gas. that fluid looked new. LOL
Looks can be deceiving on coolant. You can use a test strip on it to see if it is still good
I just got a 2011 and am having the head gasket replaced so ai will have new coolant. what other fluids do I need to worry about?
No, just coolants.
Is this supposed to be done at 100k miles?
Per Toyota yes
Is there any difference between bleeding in maintenance mode vrs just letting it run with the heater on ?aside from wasted time when the engine kicks off?
If you don’t run it in maintenance mode, your engine won’t be on, it’ll be the hybrid system on. If you run in maintenance mode, the engine will be running the whole time so it’ll circulate the coolant throughout the engine and warm it up.
Thanks I did as you said but my ac is not cooling any idea what happened.?
was it cool before? This doesnt affect the AC if that’s what you’re thinking. If your AC isn’t cooling, I’d check if the freon is low or leak in your AC system line.
what if it's low? can you simply add more coolant?
Yes, but it still needs to be changed to remove the salt build up from old coolant. The longer you go without a change the faster the coolant boils off and leaves behind even more salts
When do you take if off maintenance mode, or what do you do to put it back in ready mode after you turn on the heater on Hi??
Mario Eric, I was wondering the same. Any answer???
To take it off maintenance mode you turn the car off and when you turn it back on, it’s back to normal.
What kind of coolant you used?
Your video is awesome. I have a Prius 2013. Do I have to drain the coolant on 60K maintenance? Or is it good enough to refill the coolant only? Thanks!
Refill till 110-120k miles
Hey guys, I put a bottle of the K&W stop leak in the reservoir to fix most likely a leaky head gasket.. (burns maybe a couple cups of coolant every 10,000mi or so)
..And like 3days later I just got the "check hybrid system" limp mode thing while driving.. I also basically lost all heat in the car after I put that bottle in..
I noticed the car was also overheating when it went into limp mode... so did I clog up the system? I've always heard that was a possibility with that kinda stuff, but this is the 1st time its ever happened..
Can I flush it/high pressure it out? I was gonna drain it tomorrow and pump a bunch of water through the reservoir or that top hose.., hoping to clear out as much as that stuff as possible..,? or does it not work like that?
It also looks like the Inverter has its own reservoir and drain plug as well.. Can I 'flush' that like a radiator? Does it matter which line I use? Are they dangers to pumping water through the system? I'm obviously going to fill it with the factory coolant when I'm done, but any advice would be appreciated..
how did that go for you?
@@nastytaco420 Not well.. I flushed it a bunch.. the system would randomly unclog itself a for a few moments, but it eventually stayed clogged..
Since its like a 9hr repair job for the heater core, and the transmission was having problems too, I decided to just buy a new car. Got the awd corolla hybrid. Sold the prius for $2k to a back yard mechanic. No clue if he fixed it or not.
Hi after water pump changed screen show me maintenance mode . What’s the mean it is ? Is it dangereus or ? Pls unterstand I’m female driver . Help me pls
Perfect. Thanks
For a Prius Hybrid, you did not also drain the inverter, which should have a drain plug under the car?
We did another video for it
You mentioned maintenance mode and inspection mode
I see the you used the same Super long life coolant 50/50 for both Engine and Inverter Coolant. It should work well right?
Yes, that’s the oem.
@@NutzAboutBolts thanks for your great video and answers to my query 👍🙂
2010 prius is making a knocking noise when driving. Any way to fix that issue? Thanks for this video. Im going to change the coolant in my car today
Cylinder(s) misfiring. Do you have a check engine light? If so, go to your local auto parts store and ask for them to put on a code reader (if you don't own one).
@@troybonner91 the driving noise is a loud knocking when im driving at a lower speed. Imagine a lawnmower, that's how it is. Toyota told me its the engine

Most drain plug for the radiator is on the bottom by the back of the bumper support bracket.
Can you write the steps on bringing the car in the maintenance mode please and how to bring it back to hybrid mode before driving it. Thanks
Romeo maloco any response?
YES I did put out there how do you get into maintennae mode? I know how to get out of it by simply shutting the engine off.
How do you empty the coolant reservoir? i changed the coolant of my Prius C but the only way i saw to change the reservoir coolant was to remove the little hose from below, i did not wanted to do it since it was quite stick in there and it could break.
you can remove the reservoir itself to empty it. its either held on by bolts or clips.
@@NutzAboutBolts Do you know if the same can be done on the Prius C? i think it might be the same but i did not bothered to take a look and see how to remove it, i guess i will have to wait to the next coolant change in 100,000 miles or 10 years.
@@hedgehogthesonic3181 I haven’t worked on a prius c before, but from what I can tell from Toyota vehicles, they’re all the same, either held on by bolts or plastic clips or sometimes it’s just slid on to the body frame. Also, you don’t have to wait to empty the coolant reservoir, you can just remove the back flow hose and empty the reservoir and clean it if you want.
@@NutzAboutBolts I see, good thing that Toyota make their cars simple, well i will take a look later. Thank you very much for answering.
Thanks for you video! Do I need to lift the car to reach that drain valve? I have 2013 CT200h, is the same procedure as your 2012 Prius? I heard they are using same hybrid/power system. Thank you!
We jacked it up and put 4 jack stands under it since we were going to do the inverter coolant as well. Its better this way since you need to remove the undercover to get access to the inverter coolant. Also, both system needs to be changed out every 120k miles, so 2 birds 1 stone :)
Thanks! If I only replace the engine coolant at this time, do I need to buy two gallon coolant? or just one gallon is fine? @@NutzAboutBolts
@@jasonkung2861get 2
Is it necessary to flush the cooling system with distilled water?
no, you don't need to.
Can I just top it up with the old coolant or antifreeze
I'm worried that the Gen 3 Prius (2010) I just purchased has a head gasket leak. I performed the EGR pipe, cooler cleaning along with the intake manifold and i still get the periodic engine shake at start up. I have a OBDII scanner showing a p0301. Which could be a blown head gasket?
I just recently replaced the spark plugs with Bosch Iridiums.
Question, can you perform a block chemical test on the prius via the coolant reservoir? This should be a sure fire way to tell of it's a blown head gasket? I would assume so but you guys seem well versed in Prius and your videos, btw, are super helpful.
Ricardo Santiago, what was the issue? Blown head gasket? Can you preform that test? I have 2014, milky dip stick, cold start knocking, low coolant ( no sign of leaking on ground). No check engine light.
@@terrytorres7075 I did perform the test using the coolant reservoir and it was inconclusive. I didn't have the milky dipstick, but think for sure it was the head gasket in cylinder one. My fix was simple, a $12 bottle of K-seal into coolant reservoir and almost 8K miles later, no shakes and no coolant loss. Disclaimer, these block sealers don't work 100% of the time, in my case it did and I believe I was just lucky. I know I'm on borrowed time but until then 258,000 miles and counting.
The awful banging sound you hear is a piston preparing to slam its way through the side of your engine block. It is now dead. New engine is now required
@@metrork1 Maybe you're right but not the destiny of my little Prius. A bottle of Kseal seems to have fixed my issue. 8K miles later the Prius continues to rock along. I have been making trips to and from West Palm Beach and Sarasota and averaging 40 mpg at 70-75 mph. Amazing machine. Granted, I know the engine can go at any time and I'm ready for that till then...
@@avidskier73 Update?
Hi, I took my car to the dealer to have the radiator coolant replace and I don't know if they knew how to put the car on maintenance mode anyways after that my car over heats going over 45 MPH I think they didn't bleed out the air by putting the car on maintenance mode and that could be making it over heat. what do you guys think?
I’d take it back to the dealership and complain about the issues to them…
Hi
I have a 2017 Prius.
Do I need to add water with the coolant or just pour the raw coolant?
And any idea how much coolant I need to bleed both the inverter and the engine coolant?
Thanks
It comes premixed already. Use the pink 50/50 mix. You’ll need a gallon and a half for both inverter and engine coolant.
@@NutzAboutBolts Thank you!
I have a 2017 Prius Two with 110k miles. I bought 2 gallons of Toyota 50/50 coolant & took it to an independent mechanic. He was unwilling to flush & refill the coolant & said sometimes the engine overheat after changing the coolant. Is it true? He also said I may need 3 gallons of coolant. Should I buy anither gallon or 2 gallon is enough?
Thanks again!
@@shujayethossain6554 never had issues of overheating when I did my drain and refill. We only used 1 1/2 for both coolant system
@@NutzAboutBolts I was wondering if you are near New York. I live in NYC and would love someone like you to change the coolant who knows what he is doing. I have had several bad exepriences with independent mechanics ranging from damaging the ABS sendor to overtighten the oil drain plug. The dealer is too expensive.
Thanks again!
@@shujayethossain6554 ah, sorry, we’re in California and we only do tutorial videos. I’d suggest yelping for a reliable hybrid mechanic. This job isn’t too difficult either, just need some tools and you can do this yourself for cheap.
