I have that exact car... even color. I'm having the exact issues and the dealership can't seem to find the problem after I spent money on a full diagnostic. I went back after I found the code and they replaced the water pump. At nearly $900. A month later, the problem is back. Now you show me this and I'm sure that's the issue. Thank you so much!!!
Thank you sooooo much sir. This really really helped explain whats going on woth my 17 prius. I have 250k on it and its always ran perfect...but now, it all of a sudden needs work. I love this car so much, its been so good to me. Now its time to give back and tune her up like new. Going to bypass my heat exchanger for now....but eventually replace that part. Cheers buddy
HI!Great video and details what is going on, when you mysteriously loosing coolant, that is not leaking or not going into the engine. Just dropped off my 2018 Prius Prime at the dealer with exactly the same problem. The person accepted the car at the register said is "a known issue" for these cars and yet I didn't find almost anything online until I got across this video. I got this car as a Toyota Certified Vehicle and I am just hoping that this is covered by that or there is a recall on it. Thank you for the great video.
Yes, I had this problem on Prius v 2012. I notice when it dam on rainy or snow day engine went into shaking mode. So what I did was to losing the coolant engine reservoir cap. It help stopping engine shaking but I will have to refill engine coolant.
I had this happen 6 months after buying new…apparently coolant is routed to cat converter for quick engine warmup…it was covered under warranty…but that was a $9k warranty claim😮
It should be noted that the gasoline engines for the hybrid vehicles that Toyota produces go through an exponentially higher number of hot and cold cycles compared to a full, 100% gas drive engine. So, you will see a Prius engine, mainly from 2009 to 2014, have a head gasket failure between 120,000 and 150,000 miles. So, the newer ones are better engineered and, while this particular car was obviously used for some sort of delivery or taxi type service, we don't expect to see head gaskets failing at the rates that the previous generation suffered from. The heat exchanger is a unique element to the gas hybrid vehicle. It is an efficient use of heat and is wonderful engineering. Considering how easy it is to total a Prius, or any hybrid or vehicle with radar sensors in the front and back by any manufacturer, after an accident, those heat exchange systems should be readily available at junk yards at an extremely good deal. It's the catalytic converters that they demand all the money for.
THANK YOU. Totally correct! Same for my 2017 Toyota Prius (Canada)...the part is not available here but should be a recall and warranty. Hope to find out what happened after you made this video. Driving without heat and either replacing coolant (without a bypass) or burning gas. This is known issue by Toyota...how to get the part (1,700 in Canada AND some compensation?...help!) Have a great independent brilliant mechanic who figured this out after a lot of guesswork you know where.
I’m going through the same problem right now with my 2017 Lexus ct200h. Essentially the same car and parts. They’re telling me they need to replace the water pump but after seeing this video I’m going to have them look at the heat exchange. I’m surprised this isn’t a recall !!!
_I'm sorry sir, as a certified Toyota technician I'm not allowed to perform such a modification.

My 2016 Toyota Prius has a refrigerant leak. I fill it up every day and it runs empty a few hours later. I don't see any signs of leaks on the chassis. I've driven it for about 270,000 miles. Toyota Longo 4s said it would cost $4,800 to repair it because they found water in the engine with a probe. Is this crazy? Such an expensive repair bill!
@@monteburgesshi brother! Do you mind explaining what happened to you? Is it bad to drive the car with that leak even though I replenish the coolant whenever I can?
I'm hoping to rule this problem out, but I can't tell where the leak's coming from yet. We had about 2 tablespoons of coolant that dripped down from the front passenger wheel-well onto the garage floor. The engine reservoir only needed a splash to bring it up to the FULL line. Inverter is full. Don't see signs of any leak poking around the top of the engine, trying to look around the sides, and under the car the best I could without raising it. No coolant signs around the tailpipe. Needs an oil change this weekend, so we'll be lifting it, and looking further.
I thought it was my head gasket on my 2016 prius but thanks to your video I figured out it was also my heat exchanger!!!! Im saved lol if it was my head gasket Id be fuckeddddd
Hello, I have a 2017 Prius with 120k miles and suddenly I see that the engine coolant reservoir is empty while the inverter coolant is full. I didn’t find any driving underneath and the engine doesn’t overheat. Why is it happening and what should I do? Thank you!
116k miles on my 2017. Same problem. Same trip to the dealer which found “nothing wrong”. I’m adding a half a cup of coolant a week! So, how to fix exactly? Bypass?
My 2016 Prius emitted P00B111, P011511, P148F00 AND P319000 codes 4k miles after dealer fixed 170171P Exhaust pipe recall. my current odo is 51K and they are saying Engine has to be replaced
I noticed in the last video the new highway 101 sign. I wonder if that is a hint for us for something or perhaps a gift from a fan.. Anyway Pete, this Japan built Prius is one owner at 104 thousand miles. About 21k/year.. makes me wonder if he is an ubershare worker. Anyway. You asked me about recalls. This unit has possible faulty locking parking brake, hybrid PCU connection could short out to the box, and also if purchased from Gulf States dealers the spare was not set properly at PDI. That's all I see for recalls. Toyo unfortunately does few recalls and only if absolutely necessary as you maybe know from the service writers. Some people were denied oil ring repair if it did not drink over a quart of oil for the 2.4l-4 bangers of ten years ago.. maybe it was a TSB but I didn't care to look through them this morning. Peace to you crocodile.
And thank you for making the videos for us. Miss you on Sundays when you are off. Maybe you can post schedule a post for Sunday and take a break Monday and then back to the regular schedule.
I have a 2015 with coolant leak from bad heat exchanger. you mention that there is a 2013 Toyota TSB which says the coolant heater can be bypassed. Any idea why my dealer is unaware of this? When you say bypassed, do you mean I can connect the hoses together, or simply block them off. I assume you mean connect together, this is a $2700 back ordered part. Thanks!
@@minhphung9252 I’m sure they dealer can fix it but the TSB wont cover it if car is over 80k miles. Also TSB doesnt cover your model yr so it won’t be free.

So I had this problem & did the bypass- it worked for about -6 months or so - I drive about 800-miles per wk Later I found out that my overflow coolant was leaking into my engine & of course blew the engine- ques - how long so we do the bypass for like only -a wk or 2 ? I’m told I still need to fix the heat exchanger - I did replace the engine?? Thanks from CT
@@camposvazquez thanks so much - so I did have to replace the engine - with bypass still in place - now 25k later it’s leaking coolant on the ground - took it to dealer - they undid the bypass - and said I need a new catalytic converter

@@WilddogAB don't drive it much or at all or you could wear the head gasket and you will be in bigger trouble.

Where is your garage located?
My 2017 has a slow coolant leak. None in the oil though. Il keep an eye on this
If it’s in the engine & stop DRIVING IT ASAP - u need a new head gasket-now and fix the leak - ur going to throw a rod like I did

I didn’t find any driving underneath and the engine doesn’t overheat. Why is it happening and what should I do?
Thank you!
Two options. Bypass the heat exchanger (cheap) or replace the exhaust assembly (expensive).
Great information, I didn’t know that part even existed. It seems like over engineering in this case.
Built-in obsolescence
Hi, is it save to bypass the pipes?
Great video Peter! So this cools the exhaust?! I don’t get it. What for? Keep the batteries for getting overheated by the exhaust running near it?
I think it is to heat up the engine faster after startup.
@@tundramanq this is exactly the reason
You should show changing a Toyota wheel bearing. How you deal with the circlip?
How many miles does ot have Peter? Great analysis lookn inside tailpipe. Thot it would leak EXTERNALLY. 👍
104
HOW MANY MILES?!?!?!?
116k miles on my 2017. Same problem. Same trip to the dealer which found “nothing wrong”. I’m adding a half a cup of coolant a week! So, how to fix exactly? Bypass?

Very interesting 🤔
I wonder why they need that heat exchanger? Is it supposed to heat something, or cool something & why?
Being ICE doesn't run alot, coolant is piped thru heat exchanger so the interior of car heats quickly in sub degree weather.
What happens if you bypass the coolant line? heat will not work?
Engine will take longer to warm up
