I'm a prius mechanic, and I'll be honest, that sealant is a only a quick temporary fix but causes more damage then it fixes, the sealant clogged your radiator and all your coolant passages, literally cancer for your car, DO NOT USE

Hi what do you think can I flush the radiator or leave it like this

Hello just watched the video and my question is before adding the head gasket fix to the coolant compartment. Did you have to drain the coolant before adding the gasket fix?

Was this a 2010 model issue or did the 2014 have the same problem?

Question: did you use the whole bottle or only half? I bought the same thing, followed the directions and according to the box with the coolant capacity of the car, it should only use a half bottle. Did it a little over a month ago on my 2012 Prius V. It fixed it, but last week I noticed the check engine light flashing when I was accelerating at highway speeds, P0301 according to my scanguage. I also noticed it was low on coolant again, so I added more. It’s not shaking at idle like it was though, and driving around it seems fine. Should I do the other half and redo the treatment, see if it lasts? I still owe over $6,400 on the car, and it’s my only vehicle right now.

Thanks Jake it has fixed my car with 330000 miles

You had a check engine light when the codes came up? Or the orange triangle? I dont have CEL but my coolant resevoir looks dark and the car is loud sometimes.

I did the same thing with my 2008 Prius and it's been running like a champ.

My prius is a 2011. It has not lost any coolant or anything you describe at the beginning like hot bubbling etc But I get the engine rattling when started. Has anyone use this product with exact same symptoms? Thanks

Gotta say I had little hope of this working. Sunday my Prius starting knocking. 2012 with 170K miles on it. Monday I changed the spark plugs and cylinder one was wet. Error codP0301 Cylinder 1 misfire error. I went out and bought this stuff and put it in. First day did not work. Followed the instructions and was still banging every time I started the car up after half an hour. Did this a few times and drove around. The next day no more knocking in the morning. 3 days later no knocking. So far so good. When you put this in the reservoir it just sits an the bottom so I guess it takes a while to works its way into the Radiator. 4 days after putting it in the Reservoir I can still see it laying there. My radiator fluid is pink but this stuff is grey and I can see the grey about 1 inch thick on the bottom. Thanks for posting.

Thank you so much this is work for me my 2010 Toyota Prius no more knocking no shaking Runs 🙏🙏 perfect almost 2 weeks God bless you you help me a lot

Thats a temp fix at best. I am not a mechanic, but i replaced the headgasket myself with a help of a youtube video. Saved 2k. I spent 120 bucks on gasket, oil, radiator fluid, and spark plugs. It looks daunting at first, but once you dig in...its pretty easy.

Do you know if it works in the sec generation?

I had misfire in my Prius. It started smoking white and all the coolant was gone. It overheated so I decided to clean the egr valve/cooler, changed all spark plugs and cylinder 1 spark plug was kinda black and had oil on it. I used the head gasket fix which I added to coolant. It stoped the car smoking and no loss of coolant anymore but it’s still misfiring and sounds really bad. I don’t know what might be wrong.

Hey I have a 2014 Toyota prius that I’m fixing up and I saw this video when you mentioned these symptoms of a bad head gasket my question to you is about that product how long did that sealant last you?

I was super skeptical, but I tried it and it worked! … or so I thought.. Long story short, this stuff kept me worry free for just short of 5 months. The same issue came back, but I’m going to repeat the treatment tonight. If it works for another 5 months I’ll consider it a W Pray for me boys

hello i have a question, it did this knocking problem when i was going to start the car last night, but it hasn't recurred for 3 days, do you think it's the ignition?

Thank you man!!! You saved my car. I had exactly the same problem.

Is it the same with a P0303?

Is the cars still working?

interesting this is, I have coolant leaking under the car in my 2011 prius. I thought it was the head gasket, then a mechanic told me that if it was a blown head gasket, I would have coolant seeping into the engine block, and the coolant would mix with the oil, and the oil level will rise, and be creamy in color. Well my coolant is leaving, but my oil level is stable, and its not creamy. I wonder if the misfire I'm having is related in some way to the coolant leak. . . I filled up my tank, and a week later, without driving the car, the tank drained 2/3rds. I get that misfire shake prius have on every engine start. I wonder what else it could be if its not a blown head gasket...

I have seen the stop leak fix a head gasket for six months. Others claim longer. Obviously it has to be a very small leak and ideally has not caused overheating. Overheating will warp the aluminum heads compounding the problem. Sometimes the coolant will suck into the cylinder during a off period and causes issues since its incompressible. On Prius it is common on gen 3 engines, especially 2010-2015 along with oil burning. How is your car doing?

Where did you pour your in?

You just pour it into the coolant reservoir?

My 2010 Prius just started knocking. Check engine light turned on and it has coolant in cylinder 3. Steam coming out the exhaust and the coolant level is going down. Please help!

Is your prius still running perfectly till now?

Hey I have a 2010 Prius head gasket blew on our trip to SD. I got a bad deal I financed the car through like one of those random corner dealer lots with no warranty I bought the car AS IS... and I still owe like $6500 on it the cars not even worth that much. Trying to get $ together to replace the whole engine but then I heard of this technique... did it work for you or how’s your Prius doing?

Ours is p0303 is that the same?

How long did it last for? Did you do it again months later, I have seen no updates. thanks for posting!

How do you let the car idol? Did you put the car in n maintenance mode?

@Jake Tiesler: Jake will this additive damage / plug the electric water pump? I’ve tried the same thing you did but with a different additive from AUTOZONE and it lasted less then a moment and the engine started bubububu again and drinking coolant as a MF. plus I’ve to spend additional $490 for new OEM electric water pump (parts and labor), because that additive (different then the one you are using $70 per bottle) damaged and plugged the water pump. Please let me know. Thanks brother. Nice and professional video. Blessings and stay safe !!!

I’m a single mom and you just saved my life thanks so much ❤️

Great video! Thank You :)

Jake, can you give us an update and how many miles have you driven since the repair?

From what I understand, it’s a failing water pump that causes engine temps to rise enough to cause the gasket to fail, but not enough to trip the engine temp code. People who replace their water pump before 100k / before the gasket fails don’t have any issues in the future.

Had the same car and same problems as you did, and used the same formula. It lasted 1500 miles and then started to have misfires again in the morning, but it didn’t shake at all just a odd sound after starting and still drove perfect. I’m just going to spend $100 and fix the head gasket myself, there are so many videos here and it looks easy enough.

Hey thanks for this video. I had the exact same problem and was able to fixed it by following your instruction! So happy!

I’m about to try this. Have a 2011 CT200H, same engine as Prius. Have over 263k miles and just now got these problems come up, exactly as you described. Engines here in town are $1k... was about to just go ahead and swap the engine but I’ll try this before. Keep us updated lol

Where do you pour the head gasket fix liquid?

Very helpful nice 👍

is this still working out for you? dealer is telling me no to do this cause it causes issues with the hybrid portion.

I used the same approach. It worked once for about a year and a half. I needed it again so I did it again. But you have to be careful because I believe it made my water pump freeze and I had to replace that. Still cheaper than replacing the head gasket...

Question is here. Did you have to put more in 3yrs later now or did the one time fix it still?

Do you know if Toyota fixed this issue on the 2015 prius?

Check engine light came on first ever n shop checked it, they said coils n spark plugs, why both? 2010 prius 93k miles

Do you have a follow up? Did it work long term

Just curious, you said that you hadn’t started the car in weeks-(after using the leak seal). You then stated you had been driving it like that for a month-(after the leak seal). Did I misunderstand?

Omg i am having the same problem with my 2012 prius. I dont even drive my car that much. I work from home so no need . I will try your method. I was told to just give up sell it and whatever i get to be glad i got something for it.

I just see the video now and kind of interpreted but I don’t believe it to work for long term, anyway any update after 4 years you posted the video if you still have the prius ? Thank you

is it still alive?

Great video. I think many people do this but never talk about it. I being one of them. I have a 2010 prius basic. Paid $1500 bucks for it with 250k miles. Had a suspected blown head gasket. I'm a tinkerer so i pulled the egr system and intake and cleaned everything in hopes it would fix the intermittent shudder. It stopped shuddering for a week or so and then it's back. Still losing coolant so at that point I know it's the HG. What do I do? well, I did what you did, except I went with K-seal. Just pour in the reservoir and literally seconds later the car stops shuddering. 8k miles later it started shuddering again. Now from cylinder two. I actually did a quick test and unplugged the cylinder two spark plug and it stopped the shudder. I haven't tinkered with it yet but hoping its a fouled plug or bad wire. Like you I too like this little roller skate of a car. How many cars can go, anf go, and go and get 45-50 mpg. Granted it's not a hauler but it's a work mule. Wish I knew someone in South FL that did these head gaskets relatively cheap. In case anyone in South FL is reading this and you're that person, respond, please.

Thanks 🙏

What's that little meter on your pillar?

I fixed my head gaskets. It’s still misfiring. Should I give this a try??

This product broke my water pump. I used the blue it was much better. A little more expensive but works better

Changed sparks, coils and egr system then thermostat coz apparently it leaked! Now going for waterpump. Cleaning manifold inlet ports would be last if it's still vibrating. For leaking head gasket I might have to prove it further with a borescope scan..

Hey brother, you are my saver today 🤝

Thanks Jake, every time I go into Midas they always try to upsell me to the max limit on my midas credit card. I took my prius to 4 different shops. I will keep your suggestion in mind. Thanks!

It seems like this stuff would clog up your radiator and heater core as well.

Just used this on my 2014 with only 140k miles. Hope it works because I owe like 8k on it.

I got a 2012. It was roaring like a truck. I DID PUT BARS SEALER IN IT BACK IN NOVEMBER. HAVENT DRIVEN IT ONLY BEEM STARTING IT BUT THE VIBRATION IS GONE

⚠️🚫ATTENTION 🚫⚠️ I watched another video where they actually did the head gasket, after someone had tried using the seal sauce that you showed. They reported that it does temporarily work, but the also clearly showed and demonstrated that the gasket seal sauce gets stuck and gunks up all the ports where the coolant flows. You can clearly see the gasket seal stuff hardened on the head gasket where it was leaking (where is temporarily fixed the issue), but you can also see it clogging holes where coolant flows around through your radiator and engine. You’ll need to replace radiator too if you use gasket sealer. PS just finished a HG on a 2010, it took my dad and his friend 3 days lol 😢.

Be careful, it will fix it but then you will have to replace radiator, water pump, heather core, over and over. What happened this cover leaks and at the same time it will block coolant passageways too.

Is this fix still working for you Jake?

Hey Jake, 4 months later, how is the gasket?

That stuff eventually ruins your engine, it’s probably good to mention that

help, my engine is doing the same but no codes at all

Bro that happened to me exactly and I been to mechanic he did same think to it put some pink liquid that you show and fix the pb. he charged me 20$ .... No to bad . Hey thanks for sharing your experience 😊☺️

Sounds great. I have a 2012 Prius with 260,000 miles with same issue. I used K Seal. It works perfect. In your video, it sounded like a rattle for a second when starting. With the K Seal there is no rattle at all. Just an observation. If by chance it stops working, give K Seal a try. Good Luck!

231K 2013 Prius. This problem pretty sure is due to in whole or in part of the EGR cooler/pipe/valve getting clogged over time. Toyota did not make this part to last. I think I have a small leak on head gasket. I also am reluctant to try the stop leak fluid because I've heard from multiple places that it is temporary and only a matter of time until it fails, unless I suppose one gets lucky on a very small leak. But then there is also more concerns that it has a good chance of causing more trouble down the road if the stop leak fluid clogs up in other places it shouldn't (which is maybe why as you mentioned the other person put the stop leak in a diff location). Your logic makes sense though when weighing the cost to benefit/value of car. You just confirmed one of my suspicions - The gurgling of water or coolant i thought, and it happens usually on the first start of engine or at certain temps. It gurgles for a few seconds. I also think my coolant level has a very slow leak going into engine causing the misfire briefly to happen a couple times every 100 miles I drive. If I replaced or cleaned the EGR cooler every 100k or sooner I believe it would have avoided the head gasket failing from the pressures over time. I don't get the cold abrupt starts, never did, which I think I prevented by cleaning out the EGR cooler, actually I replaced it the second time at 231K now, and cleaning the EGR valve/pipe along with the manifold. The symptom I get is on slow accel only, slight misfire then goes away quickly (there's a youtube video about this, slow accel misfire) I want to keep my prius as long as possible so I may have someone replace the head gasket or I may try it following a video, but it looks like too big a job.

Still running good

You know, that stuff does work lol

Yeah I'm having this issue because I let my coolant get really low. I didn't even notice. I went and got the oil change and I guess they didn't check the fluid levels for me like I thought they would. Shit and as I'm writing this the check engine light just came on. And it sucks cuz I was just getting ready to sell this fucking car. So hopefully this will work to fix it

maybe now would be a good time to sell it while it is still running well?

I had a 2010 Prius with 240K miles when a check light came on while driving in fast traffic on a very hot day. The car overheated and began to misfire. So it seemed. A motorhead neighbor mentioned a gas station mechanic he'd reccomend. I trusted the suggestion and ignored the messy shop. The problem was misfire on cyclinder #2 -- his computer said. He'd repair it in a flash by replacing its coil. He tested it himself, charged $300- then quickly left - abandoning his reputation. It solved nothing. I'd long ago learned that Toyota dealers are killing their brand with smooth personal relations and outrageous repair. I'd discovered that shortly after I bought my first Prius from a dealership. It was a year old and "certified", which meant nothing. It looked like new, but I soon found it had been in a major collision that required frame straightening. Their technican agreed, but the dealer didn't. The car looked new and ran well, but overtime small issues grew because of the collision. The overheating occurred after I added 200k miles. Head gasket they said. They'd replace it in a day. But, when I told them that I wanted to see what what the gasket showed, the repair required two days and a weekend. Toyota corporate, I learned, has no control over how dealerships make their money. After awhile, I decided to replace my Prius with another 2010 that had the same options but with 50,000 fewer miles. A small RI dealer promised to fix any problems at his expense, and half the cost for a year after that. But then I realized he was playing a game of waiting out the lemon law limits. 1,000 miles. On my own, I tackled the problems according to severity. The EGR problem was easily solved with Rislone cleaner, And BARS Head Gasket Fixer solved the headgasket problem in 20 minutes. The gasket fix continued to improve the more I drove my car. Two solutions saved several thousand dollars. Some easily solved problems --an ABS light and an engine check lite. The speed sensor connector wire to one of the wheels was disconnected. Reconnecting fixed it. The car also has a metalic rattle because of an exhaust pipe hanger. Otherwise it's quiet. Some DB high temp iron adhesive should fix it, if not some wire wrap probably would. My engine runs smootly, power and all, but now it's time to address the 43 mpg where I'm hoping to find 5 mpg more.

Any updates?

Actually, you don't pour it in the resevoir. Pull an upper radiator hose and pour it in there. There is a restrictor in the small line to the resevoir, and if you plug this with leak stop, it can build pressure and blow coolant hoses off...ask me how I know!

If I ever dumped something like that in my radiator I’d sell the car immediately afterwards

Hi!. I had the same issue with my 2010 Prius just last week and I"m so glad I stumbled upon your video about this product. I almost sold my car for $500! My car was shaking aggressively with white smoke coming out at the tail pipe with very strong odor. I got the product and used it exactly what the box instructed to do. I couldn't believe it did a miracle to my car! The noise, shakes and white smoke were gone after 20 minutes I poured the product in the radiator tank. I was able to drive my car to work on the freeway that same day at 65 mph. Thank you so much for posting this video. I also would like to know how your car is doing as of right now?

It fix my 2012 Prius for about 6 months I’m repeating the process again today

Bars aluminum radiator sealant fixed mine :)

How to fix a Prius: 1. Sell it

I replaced my water pump now my car is shaky idk 🤷‍♀️ what’s wrong now

Thanks Jake and good luck with the 40 dollar fix . Keep us updated . Was a warranty on the 40 dollar fix ? Miles ? Months ?

Highly don’t recommend doing this!!! It will do more damage to the engine… and water pump will fail if it gets gunked up

I hear this head gasket repair fluid will eventually fail and also destroy the water pump. But it also depends on the condition of the car and your budget

I understand the situation with the value of the car vs repair cost but that isn’t really a fix. Wait til you need heat in the winter and find out it sealed your heater core up as well.

If you can clean the entire EGR system and intake manifold approx every 100,000 miles, replace your PCV valve and install an oil catch can you may be able to avoid these issues. I have a 2010 Prius with 115,000 miles and I have done this. It burns no oil and has no knocking. Fingers crossed it stays this way for years to come.

if prius shakes it's pcv valve. 15 mins to replace

That actually doesn't fix the head gasket, it is temporary masking the issue, which still exist... It will actually make it worse...The only way to truly fix your head gasket is to take to the mechanic to fix it for real...

For Anyone watching this & are planning to do it to their own vehicle….DONT! It’ll work for a month then it’ll fail, If you decide to use head gasket fix in a bottle the stuff you wanna use is called “MOROSO CERAMIC SEAL” It’s about $25 & works every single time, My current car failed the gasket at 200k miles , After Moroso it’s now at 272k & still going strong…..Remember to flush the cooling system extremely well & remove the thermostat before the treatment, Then drain it out & let the Moroso cure for 24 hours or longer “I let mine cure for 48 hours”……Flush the system after the 24-48 hours , put the thermostat back in, Replace with fresh coolant & your good to go

🤣🤣🤣🤣🤡🤡🤡🤡👆👆👆👆👆🤮🤮🤮🤮🤮 The downside is you damaged the radiator the throttle and heater core for sure. The real problem is that you bought this car so cheap because it already had a Gasket problem. Who ever will do this they will damage their car even more.

Please update your results. Also: you saved more than $300 a month.

Stupid plastic water pump crazy idea from Toyota then even more silly idea no normal temp gauge crap basic engineering failure and to top it off these crazy thing spin motor over so fast on startup if the water from blown head gasket in cylinder can cause motor to hydraulic and bent break condrod videos on u tube with wrecker that has lots motors in a row with holes in block from conrod

And now you sell the car to a other guy, and he has a crappy car?

(sigh). Replace the head gasket.

Don't do this! It will appear fixed for a,very short time but will cost more to repair and could do a lot more damage! The shaking is because your antifreeze is getting into your cylinder overnight! This clogs the leak temporarily but clogs a lot of other required cooling ports in your engine!
