2010-2015 Toyota Prius Engine coolant drain and refill
ฝัง
- เผยแพร่เมื่อ 8 ก.พ. 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

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?
This channel is such a hidden gem! 💎 Thank you for sharing your expertise in such a beginner-friendly way!
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
Put a piece of vinyl tubing on the radiator drain petcock, and run it into a jug/container. No splashing!
Thanks for helping me diagnose this. I’m headed Valvoline but I didn’t know where to turn before. Thanks.
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.
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
Great Prius maintenance video!
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...
Excellent video. The explanation was very good !!
Thank you for your video i use this videos for change the spark plugs, transmission oil and the water pump and coolant
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.
Absolutely what I needed, thanks 🙏
helpful video for "maintenance mode."
Thank you for this video. It really helped!
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
@@woprconner 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
Thank you so much for those information sir that gain our knowledge thanks and awesome
Спасибо.
great videos man. quick and easy and great quality!
+Jesse Ramirez thanks!
I now know the cheat code to my car. Thank you.
Thank you very much. So well done!
You're talented
Great video per usual.
+Mr. Buttermaker thanks
Thanks again for the great videos!!!!

@@NutzAboutBolts hey is this the same coolant you use for the inverter coolant change and what is it called exactly the coolant ?
VERY INFORMATIVE THANK YOU
thank you easy done with your help.
Thank you for the helpful video!
You’re welcome
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?
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.
How long should it take for the fan/thermostat to kick in?
How long should I let it run with the heater on?
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
Perfect. Thanks
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.
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
Is there not, an engine block drain plug, also? All the coolant you are getting, is out of the radiator bottom?
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 does it good to inspection mode do I wait
How about air bleeding the system?
What is wrong if the fan never turns on? Been having overheating issues. Sensor?
Thank you!
Np
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.
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 !
You don’t turn the heater on when you are on the maintenance mode?
Thanks!
Thanks for this video places want like 230 bucks to flush and replace.
Yeah they’re pretty pricey
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?
If i have a Techstream what i need to do after refill ?
Will it work on the Camry hybrid?
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
How much coolant did you use?
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
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 Much appreciation, K.A
@@kumara5492 Appreciation, brother
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?
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
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
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?
I used an Airlift tool when I refilled the coolant. It eliminates the hassle of the bleeding process and speeds things up considerably. The third generation Prius has a very extensive cooling system. Air bubbles are real concern. I also squeezed the radiator hoses (from the bottom of radiator, to remove air bubbles) after the thermostat opened in the engine.
+farmerinchico you know, the funny thing is, it didn't take long for the engine to heat up and bleed all the air out of the system. It was much faster than my Honda Accord when I bleed it. We covered up the plastic under panel too early so we used the over flow hose by the coolant reservoir to check if it's hot enough, and sure enough, it was hot and a couple minutes later, the radiator fan kicked on. I think people make these hybrid vehicle maintenance out to be harder than it is, when it's really that easy.
+NutzAboutBolts It's all those noises a Prius makes as it just sitting in the garage: )
+farmerinchico I know what you mean lol!! Darn Prius noise.
+NutzAboutBolts
you didn't flush the system
21boxhead
that's why its called a drain and refill...
What kind of coolant you used?
If anybody is watching this video just know this process is incorrect! You will be fine if you stick with the same coolant more than likely, but just realize since he didn't drain the cylinder block drain cock plug most of the coolant is still in! Don't accidentally mix it if you're trying to swap colors! Coolant capacity is about 5 more quarts than he was able to get out just draining the radiator and leaving the coolant in the engine!
How do you flush the engine
@@stn7172 pull a line on the exhaust heat exchange and let it drain. For filling you use the burp port near the dash.Just open it though. You fill up to the burp line on the coolant tank.
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.
@nutzaboutbolts I’m new to your channel but so far I love it. This is the only video I have questions on. Any clarification is appreciated. I tried seeing if anyone in the comments had the answer first but no luck.
The questions are:
At 1:52 after you’ve drained the original coolant and closed the valve by hand, how did the reservoir drain again? Did you open it up again off camera?
At 3:16 to enter maintenance mode, do you push the power button twice WITH your foot on the brake or off?
You also mention a maintenance mode and an inspection mode. Are they the same thing just a different name?
The reservoir uses vacuum to suck out all the fluids out from the reservoir due to the fluid being drained out of the radiator.
Foot off the brakes when pressing the power button.
Maintenance mode is for the engine to be on all the time without the hybrid system being on.
Inspection mode is to use to flush the brake fluids by using the electric brake pump to flush out the rear brake calipers.
@@NutzAboutBolts so even when we close the valve at the bottom, it will still continue to drain when it’s filled up again?
@@Jeremy-vz9gr no, as long as the petcock is open, it’ll keep draining out the coolant.
1) Toyota Prius has two coolant reservoirs. You did NOT say anything about the reservoir on the driver side. Is that drained in a different way separately or are the two reservoirs connected to the same system? 2) Do you recommend getting the engine hot before commencing with the draining process? 3) How do you make sure the coolant in the heater core is also drained?
Yes, we know this vehicle is equipped with 2 coolant reservoirs. The one we’re doing on this video is for the engine coolant, not the inverter coolant reservoir. We have a separate video on that where we explained how to service that as well. You can drain the coolant when it’s hot or cold, doesn’t matter. The heater core will drained as much as it can, but it’ll have a residual amount of fluid in there still but it’s fine. Just follow the video and you’ll be ok. Make sure to use Toyota 50/50 pink coolant for this service.
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.
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
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
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.
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
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
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
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
THANK YOU!!!
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.
You mentioned maintenance mode and inspection mode
Why maintenance mode? The engine runs with the hybrid system on? Seems fun to control the computer with such an obscure button pedal mix! Thanks I will definitely plan to do this myself, slowly and carefully!
Maintenance mode bypasses the hybrid system. It’ll let you run the engine only so that the engine gets up to the proper temp for the thermostat to open up to finish bleeding the system from air bubbles.
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 👍🙂
I could flush the engine coolant of my Gen III Prius (2013) without opening any panel at all. First I memorized the position of yellow knob of valve which was visible from top . Then there was a rectangular hole (aprx 6" x 3") in the sheet metal at bottom where I could put my arm and my hand could reach the valve at the estimated position (reach of others may depend upon the thickness/girth of their arm). With some effort I could open the valve by hand and most of drained coolant came out through another smaller hole in the sheet metal, though not very cleanly. Around 1% of coolant splashed and came out from a couple of other holes. In retrospect, I wish I would have drained slowly and had additional pans ready which may have reduced the mess. After draining I could close back the valve from the same hole at bottom.
Yep same here (2014 Gen3 Prius) @ 155K (first one I think - liquid looks good). If you ONLY have to drain the engine coolant (the inverter was replaced by Toyota so they changed that coolant), you don't need to remove the panel. Easy rolled on ramp, to reach in there and turn (if really slow it drips straight down, if faster it will splatter and will come out 2 holes further back in the cover as well. I cut a gallon milk jug to collect those secondary drips. used dr.prius app to put into maintenance mode and torque app rev to 2500rmp and heat coolant (89c stated boiling in overflow, no fan though).
I used Zerex Asian pink for toyota. Same organic coolant at $11/g vs 33 at dealer a long drive away. easy peazy...
@@alaind831 I have same 2014 Prius. We have to change inverter coolant???
just like the engine one it has a limited life and could get dirty and is exposed to heat as well...looking at maintenance log p50 it shows [] replace engine/inverter coolant at 100k / 10y BUT inverter is 150k - with this side note:
3) Initial engine coolant replacement at 100,000 miles/120 months. Replace every 50,000 miles/60 months thereafter.
Initial inverter coolant replacement at 150,000 miles/180 months. Replace every 50,000 miles/60 months thereafter.
Refer to “Engine/Inverter Coolant” in the “Explanation of Maintenance Items” section in the back of this guide for
more information.
@@alaind831 what guide sir?
@@terrytorres7075 "maintenance log page 50" as stated above
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...
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
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!
What is inspection mode?
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
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??
Faded or loaded off the Ron
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.
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
These videos are fantastic..thank you so much!
I am in a bit of a jam as I forgot the sequence and drained the fluid before removing the fill plug on a Gen3 Prius. The fill plug is now 100% stripped, rounded out even though I was using a 10mm allen plug...not sure how this could have happened. Anyway,, it is stripped and interested if you or anyone here encountered the same and, if so, how it was fixed? I am close to drilling out the plug however concerned of accidental damage to the threads and/or metal shavings inside the transmission case (and think even compressed air might not work given there is wet fluid liner inside.
Which fill plugs stripped? For the transmission?
@@NutzAboutBolts The top fill plug for transmission, for this video. The plug that is tucked behind the axel w/very little room to work. The 10mm allen socket plug went from looking like a square to now looking like a circle. Tried vice-grips on the outside, no luck and that chewed up the outside a bit....the plug continues to degrade.
@@PixelRogue3 try using a flat head screw driver or something sharp to create a dent, and use a hammer and hammer the bolt in reverse to twist it out.
Think there might be one shot left to create a dent (did this earlier w/effort of knocking it loose.) To confirm, 'in reverse' you are saying hammer the same direction to unscrew (counter clockwise?) No risk to damaging threads?
As backup, is there any other way to fill the transmission (with a close measurement on volume?)
UPDATE: Used a chisel to create an indentation, then screw driver and once it had a grip it spun out as if it were brand new! Happy days. Thank you!
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.
How does the air in your heater core bleed out if you already put the pressure cap on?
The radiator fan turned on, there’s no air in the system.
How much coolant should I buy if I'm going to do the inverter and the engine at the same time?
2 gallons.
Thanks!
ANY HELP IS APPRECIATED!
Can't figure out why I have no hot air. Changed blown head gasket, changed water pump and thermostat, and still no heat. Bread the system for 45 min to get no bubbles in a raised funnel. If I wait for 30 min, the cabin heat warms up to hot, but as soon as I hit the A/C on button, it starts blowing cold air again. (Room temp).
If you turn on the a/c, it’s not going to blow hot air, it’ll blow cold air
@@NutzAboutBolts that's not how it works. A/C should blow hot air if the temp is set to max. I have 2 prius, and the other one works fine.
Hi NutzAboutBolts, thanks for sharing this video. Do I need to run things in Maintenance mode if I'm just adding to a system low on coolant?
Nope
@@NutzAboutBolts Appreciate the quick reply. To ease my anxiety, I think my prius C 2014 is low on engine coolant which is generating a check engine light. I notice two places where I can add coolant. One reservoir looks like the one in the video but I see another one on top of what I think are radiator fans. If I add coolant to either inputs, would I need to worry about pushing the air out of the system? Thanks so much for your time.
@@bch6707 from the looks of it, I see your inverter has a reservoir but I don’t see your engine coolant has one. In that case, you can remove the radiator cap and use a spill free funnel to add coolant from top.
@@NutzAboutBolts Thanks a lot for the follow up. Last set of questions I had was that I only noticed the coolant was low from not seeing any pink in the "expansion tank" that's closed by a black cap labeled coolant. It sits next to the radiator cap. Should I not ever being filling that up? And how would I know if I added enough coolant to the radiator?
@@bch6707 There should be a full and low hash mark on the coolant reservoir to tell if it needs refilling 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
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.
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...
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.
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
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 ???
