- This is an overview of the steps needed to replace a 2010 (3rd gen) Toyota Prius head gasket. For more details, consult the toyota workshop manual.
Note: The car has been driven and now sounds amazing (even though it didn't sound like it without the exhaust).

The exhaust , the gear closest to the windshield, will have a blue spray mark next to the gear tooth to be aligned with the timing chain colored link. The intake gear, closest to the radiator, will be aligned with the slit that has a punch mark on the face just below the slit. The third colored link down at the crank shaft will be aligned with the punch mark upon that gear face. That's it. Just recently replaced my head gasket and followed the above instructions and starts and runs good
Awesome video man! I just completed a head gasket replacement on my 2010 Prius thanks to your video
Nice!
The 2010-2012 Prius and Prius V had weak head gaskets. It's important to change the poorly engineered electric water pump at 100k. The impeller has a plastic ring around it that eventually breaks/splits after a certain number of heat/cool cycles. A lot of head gasket failures are attributable to the electric water pump. That problem plus the EGR mess, the water cooled CAT, the PCV valve being mounted too low on the block make the GEN 2 much more dependable. The Toyota engineers blew it on the GEN 3.
Oh wow. Are the 4th gen Priuses more reliable?
I am not sure if any of these deficiencies were addressed. Surely, the change to lithium batteries was a good step for reliability but they are not user-serviceable like the old Nimh modules. There are a ton of head gasket videos on Gen 3 on You Tube. Just look up 'Gasket Masters". Many shops won't do a head gasket. They get a used engine instead. Besides a new water pump at 100k, the Gen3+ needs a catch can. There is also an updated EGR 25620-37120 and intake manifold 17120-37054 but owners are saying there is no improvement. When the intake manifold is removed, it is filled with oil. That oil when burned, is not good for the catalytic converter. That's why the Gen 2 engine is simpler and is the Prius that can go 400k with minimal issues.
straight forward job !!! I will stick to my old engines you could change the head gasket by the side of the road, maybe not in Canada in winter but certainly over here in France.
Its still a job you could do on the side of the road, the problem is you'd be there for a week..
Previous owner hit the windshield on outside too right before we bought it 😂. By the way, really critical to change the pcv and clean the whole egr system. That adds quite a bit of time!
Really satisfying interesting film Ludi. So much stuff to come off though, wow. Will stick with my 2.25 three bearing engine in my 2a Half Ton.
Keep up the good work. 😊👍🏻
Hahah thats the way I want my range rover to be, simple !
I used a bottle of Steel Seal to fix my head gasket, drained the coolant, removed the thermostat, flushed the cooling system really good, Then use a radiator cleaner to clean the cooling system , Make sure to flush out all the cleaner 100%, When engine is 100% cold add steel seal with distilled water, turn heater on high & let idle for 30 mins with the radiator cap off........Let it cool for 1 hour the let idle again for 30 mins with the radiator cap on...........next morning let it idle for another 30 mins then removed all water from the system to let the steel seal cure for 24 hours, Replace the thermostat, fill with coolant and your good to go. Mine has been running perfect for 70k miles now as i use the car for uber & lyft, Only cost me about $120 total.
Well done man ! Love straight piped Prius ! 😁
Hahah sounds different for sure 😂
Wish i watched this before I did mine. I missed those 2 beads of sealant under headgasket. seems to fine so far. Also note there is a bead of sealant around one of the timing chain cover bolts. I have done Civic head gaskets before than this took me 9 to 10 hours total. What a pain in the back lol. It makes a clatter on the first start up. Its a 14mm triple square socket. inverted. They sell a kit at Autozone. was 21.99. I forgot the hook up the Pcv hose on start of and got all kinds of failure to start check hybrid system on the first start. easy fix. though. Only of a Toyota would you not buy a new timing chain tensioner. LOL. I bought a new head gasket and head bolts. I reused everything else. I used Honda bond on the sealing surfaces. It seemed to be they over apply sealant from the factory because a huge amount was pushed out inside the cam area and timing chain cover. I went lighter than they did. Fear of sealant clogging something. I also left out the deaded EGR stud on install will save lot of trouble later down the road. It needs to be cleaned every 50k or so. Cheers. subbed. I did a time-lapse on my channel. czcams.com/video/5mxdjthsbuQ/video.html
Yeah I was kinda worried of getting sealing in the oil feed myself! The next time I have to do this I might be able to get the time down to 10 hours like you ! Glad you enjoyed the video :)
Thanks for the info on the PCV hose! I started mine up after doing a head gasket and it ran horribly. After realizing the hose was disconnected, I connected it and it ran perfectly! I was literally so frustrated before I figured it out that I wanted to scrap it haha.
10:43 You don't have to make a puller. You can use two of the shorter 12mm water pump bolts from right next door to remove the harmonic balancer, but clean the hole threads first of any road crud so you don't mar the bolt threads, and oiling them helps. When the bolts touch on the timing cover, alternate little equally partial turns on each bolt to back it off evenly.
The Toyota manual suggested using a puller, here things get very corroded so I would not want to risk putting excess pressure on that thin timing cover.
@@ludwigseeley6359 A fair point. I live in Southern California, so there was no corrosion for me to worry about. I see from outside of your shop that you are not in the same conditions. 😉
Pretty solid video . I’m on the fence @ 100,000 miles wether to sell my CT200H or tackle this inevitable job
Don’t fix it unless it’s broken! This one had 186k miles so yours maybe has a long way to go.
Mine did not go till 250k miles. I did it in a week casually working on it. I had new valve seals put in, and the valves cleaned up, added a catch can setup as well. Glad to drive it many more miles. The felpro head gasket is good for these compared to oem has more sealing material.
Awsom!!!
36 ftlbs torque for head bolts. 5:30
where can I get that apron that you are wearing from?

That smoke you saw at 9:38 - mine did the same and I immediately turn it off afraid to turn it back one, what was that smoke, did you do anything extra at that point?
Hi its worthed to fix the headgasket and the car backs to normal or still issues
Yes of course, when I took it apart the cylinder walls still looked perfect so the engine should be good for a very long time!
@@ludwigseeley6359 thanks I'm going to fake it to fix thabks
@@ludwigseeley6359 that helps nobody gives info after replace head gaskets it's going to be pricey
Please loose the music!
Please learn to spell
How many miles did the car have when you did the gasket?
About 300k
@@ludwigseeley6359 thanks man. Subscribed!
It's hard for Gen 3s to last that long.
can you put amazon links in the description of the really important tools to do this job?
Pretty sure there was only the 12 point 8mm that was out of the ordinary, the rest is normal stuff :) (you can use an allen key or triple square if you dont have it) Also need a custom little puller for the harmonic balancer!
I just finished up on replacing the head gasket on my 2010 Prius. The head bolts of the Prius require a metric m12 triple square male socket. All of the rest of the bolts require a good set of metric sockets ranging from 9mm to 19 mm female sockets along with the 3/8 inch or 1/2 inch ratchet to go along with what ever drive of socket you are using. You will also need a good torque wrench. Do not use a Allen wrench as shown in this video as for the head bolts. You stand the chance of stripping out the center of the head bolt. A life time membership for online Haynes manual can be purchased for around $25.00. It will have all the torque specs and procedures you will need to use along with pictures. Just so you know, lifetime warranties on tools can be found at Menards for half the price of Craftsman tooling. Also, purchase a good head gasket set from Felpro.
@@metrork1 which Allen heads do you recommend for the torque wrench??
Also what makes felpro good for the heads gaskset
@@davidvalens3337 I recommend no Allen heads. Use a metric m12 triple square male socket for the head bolts.
Do you need to replace water pump? Did yo ever replace it on your Prius?
Not sure if previous owner did but I did not.
Did you notice milky oil cap after this job?
No but that’s possible
@@ludwigseeley6359 The job was done about 2 months ago by a professional shop. Even after 2 oil changes, I still see the milky foam on the oil cap. I clean it every time but it keeps depositing. I took it back to the shop and they told me that it could take up to 10 oil changes to get rid of the coolant...I'm not sure if that's true :(
@@FWDSlip Sorry I read that wrong, you should NOT have milky oil! Oil should float on coolant so the coolant will be the first thing to come out of an oil change technically. So 10 oil changes seems pretty bogus.
what's the part that you compress ? and where goes? Thank's
timing chain tensioner
I hate my gen 3 prius, sooo many problems and only 135k miles on it. I leased a 2017 corolla and returned ot when it had only 21k. It had lot of little issues from quality control to creaking noises when going up into a shallow driveway. I will never buying a Toyota again, what a joke.
