I completed replacing the bypass valve on my 2020 Rav4 using Hot Shots BD Garage method of removing valve from existing hose. Took me about half an hour to wrestle off valve using three different size flat head screw drivers as prying devices. Installed a hose clamp on install of new part. Bled the coolant system with a no leak funnel kit ($20 on Amazon). Total cost out of pocket cost $75. Got quoted at Toyota dealer $700 for repair. No more "engine maintenance required" warning. Thanks Hot Shot!
I purchased a Chinese manufactured aftermarket part compatible with part #16671-25010. Amazon price $39.95. I don’t believe there is a lower coolant valve as he mentioned. No issues as of the time of this reply.
Hey guys, this seems to be a manufacturing issue with Toyota, for this car. Has any of you checked with Toyota and asked them what the story is? ... i mean, their mistake, and we pay for it. ... i don't think so!
There was a class action lawsuit started on Monday 6/10/24 regarding this exact issue. There is a defect in the control valve and Toyota knew about it and didn't notify customers. The defect caused cracked valve, defective valve, electrical system problems, engine problems and overheating problems. The lawsuit alleges that they knew of the defect and should be responsible for the repairs, issue a recall or buy customers vehicle.
My Rav4 2019 started showing this warning few days ago only when I turn on the AC otherwise it doesn't show up , also the coolant tank is 99% empty (topped it 2 months ago) which is worrisome This is a bad rep for Toyota and its reliability as a consumer-trusted company
@@markjasonlacson there has to be a way. I'm currently in the process of replacing it. I'll play around with the old part and see if I can disassemble it and fix it
@@RedPanther2030 if you do that you get a big problem, this vehicle is cooling systmen is running by coomputers if you do that you might end up confused the computer and end up destroying your cooling system, but it’s your vehicle you can do whatever you want with it.
@@geraldevans2535 when trying to get the bypass out of the hose, there’s a 90% chance that you’ll demage the hose. part comes with the hose, is better that way.
How has it been so far? The notification came up, and Im debating to DIY this or better of just having them do it. Ive read that the hose had to be replaced too but not sure
I took it to Toyota last week and they quoted me at about $600 in UT to change the “coolant control valve”. I haven’t gotten it fixed just yet, though since I might have a friend help out.
I have been also driving it for 4 months after it came on, and no mayor issues but the annoying message in the dashboard that requires maintenance that’s all
@@rustyg.7143 how's your rav4 so far? I've been driving mine for 9 months after the notification showed up, now I got a blown head gasket. My coolant was draining fast and no visible leaks. Turns out it was going into the engine
Just about to change this on my rav 4 due to the same code, after researching online and confirming with a shop. It opens the valve when the ac kicks on from what I can tell. If I were to drive without the ac on, it's very unlikely that the code will pop up.
@@tthanhtamae86i did it myself but i got the bypass with the hoses, that’s the best way to do it. spend $95 bucks for the part and $20 on a gallon of coolant. dealer wanted $850 for this stupid job.
@@pedroaquezada Nice, in my area the part is $200, and coolant $30. Dealership says its a common issue and they fix it all the time. I have extended warranty but only water pump is covered… they quoted me $200 to “see what the problem was” and said the job is $1000. Changed it out myself, the job was a littler harder for me because the hose clamp near the Bypass valve was hard for me to reach
@@tthanhtamae86 oh yeah i forgot to mention the $200 quote charge, that’s ridiculous. i had the same problem with the clamp too, man that was a pain in the a** for me. we have 2 rav’s in family and both had the same problem with less than 100k miles, there should be a recall for this issue, bad point for Toyota right there!
How hard is it to get the hose back on that barbed connector? I understand it's pressed on which is why people buy the valve with the hoses already on it.
If buying with hoses 16260-F0010 or if only bypass valve it is 16671-F0020. Hose is tough to remove. Also no one posted clearly how they did they remove the hose

Do you have the part numbers for the upper and lower coolant bypass valves?

There’s currently a class action lawsuit against Toyota for this very part.
Toyota is being trash lately. Look at what's going on with their engines in the new Tundras. They're destroying their reputation.
I would like to get in on this. Mine is doing the same thing.
As of today, August 2024, a Toyota dealer in Sout San Jose (Capitol Toyota) has an estimate of $1K just to replace that valve
775.00 to replace in 2021 Rav 4
@7983usmc do it yourself. It's much cheaper and there are bunch of tutorials online
Where did you buy tye bypass valves from and what are the part numbers of both?
Hey guys, I just change the one on the top, but check engine light came back on, so I guess I will change the one in the back of transmission.

There is currently a class action lawsuit, filed in July 2024, for this very issue (Corolla/ RAV4 2019-2024).

did you get it fixed already?
Coolant gets inside the plug connector that’s how it triggered it!
Is there a way to fix that part instead of completely replacing it?
@@RedPanther2030unfortunately there is non! 😢

best way to do this is buying the bypass with the the hoses
Why change the hoses too?
Not really, you can just replace that part if you know what you're doing.
@@RedPanther2030 i bet you haven’t done it. 🤦🏻♂️ if you say that you ain’t know what you talking about.

@pedroaquezada if you're careful enough you can do it.
It’s to pre condition the engine in start up to put the vehicle in closed loop quicker don’t admission reasons especially California vehicles

@leahtangedal5171 are you still driv8ng the vehicle? I have to drive to work tomorrow and this just appeared for me as well.

@@pedroaquezadayeah I was just quoted for $600. A little cheaper, but pretty steep considering the job.
The second bypass valve is installed on back of the transmission.

Easy
What is the part number?
