Either the Coolant Bypass Valve is now covered by extended warranty or my dealer made a huge mistake

Hmm, only applies up to year 2021.
What valves are installed in 2022+ models?

I ask because it's odd. The F0010 item still shows up as the "Water By-Passenger Hose Assembly #1" part for 2022 vehicles. So why the PDF only showing up to 2021? And as far as I know, F0310 or F0300 was not any part number until now.

And for readers here, Toyota has weird names for parts, "Water By-Passenger Hose Assembly #1" is what Toyota has on their parts site. Docs may show "HOSE ASSY, WATER BY_PASS", but the "pass" part is "passenger" on parts site. Very weird.

Perhaps the original valves in 2022+ are still covered by the standard 36 month warranty? And when they fail they will be replaced with the new part.

The customer support program 24TE04 appears to be an extended warranty program for older vehicles up to 2021 whose 36 month warranty has expired.

The same defective F0010 valve was used in ALL gas models (probably hybrids too) right through 2023 and early 2024. Toyota made a MISTAKE with the FEB 2021 free repair cut off. My model year 2021 was manufactured in April 2021 so I am NOT covered by the support program. My Basic Warranty (3 years) is expired. If you have a 2022-2024 and drive a lot of miles, then your Basic Warranty is ALSO expired if you exceed 36K miles. So in all these cars made AFTER FEB 2021 YOU ARE SCREWED!! You have the defective F0010 valve and no free repair if you are out of the Basic Warranty.

My '21 production date is July of '21, so I am also out of the three year warranty period.

Perhaps there was a change in production of the valves, but the part number remained the same? Has anyone with a production date after February '21 actually had their valve fail?

My initial thought was that Toyota had secret information the coolant bypass valves made by AISIN before FEB 2021 had a manufacturing defect --either in the electrical internals or the plastic. I was hopeful my April '21 valve was better somehow. Last night I tried to do a quick scan using the forum search bar for all 5th gen posts about the coolant bypass valve to SEE WHAT MODEL YEARS forum members' cars had the valves replaced on. I gave up after an hour because there were too many to read. I only found the valves being replaced on 2019 and 2020 model years. The problem is that later model years still may not have been driven enough miles for the valves to fail...or people with later year failures just don't post in this forum.

"The specific condition covered by this program is for a small engine coolant leak that can occur from
a specific valve that can attow coolant to drip on other parts of the vehicte. This can cause "Engine
Maintenance Required" to be disptayed on the instrument cluster or cause the A/C not to function
normalty. lf the condition is verified, the vehicte wiLt be repaired with a new flow shut-off vatve under
the terms of this Customer Support Program."

I don't like that: "small coolant leak " only.
Some coolant bypass valves can fail because of electrical problems or just "stack open".

Yes that wording is goofy. We in this forum have known for years that the internal mechanism and electrics on the valve can fail WITHOUT an external coolant leak. However the valve can ALSO crack and leak externally.

Also very strange and "cover your ass " language in the CSP because if the plastic valve DOES crack externally it can cause the engine and coolant reservoir to leak coolant, potentially resulting in the engine overheating and failing...yes the coolant will drip on other vehicle parts but Toyota fails to mention the engine could blow a head gasket.

This afternoon I spent a couple of tedious hours on the NHTSA.gov site looking for RAV4 coolant bypass valve complaints. I went through all the owners "complaints" filed for the model year 2019 through 2024 Rav 4 gas models. I used the site's subject buttons to focus on both "engine" and "engine and cooling" though I also checked out "electrical" and "unknown". There were several coolant bypass valve complaints for both the 2019 and 2020 model year cars. There WERE a couple of complaints for the 2021 model year. There was no way to determine if the '21s were manufactured before FEB of 2021. There were NO coolant bypass valve complaints for the 2022 through 2024 model year cars. Toyota WOULD know exactly how many valves failed for each model year car, and at what mileage, because they would get that information from the dealers' warranty claims records (for cars with valves failing within the Basic Warranty period). Did Toyota find that the valves quit failing after FEB 2021 production? Who knows. Toyota ain't saying.

Went to my dealer and got a print out of the customer support program 24TE04 (it was a hassle with the service department, but that is a another issue). I scanned it into a PDF file, but unfortunately, it is too large a file and this forum's server will not let me attach it. Not sure how to post it with that size limitation; perhaps I can leave off the last few pages which are just "questions and answers".

Somethings to note:
1. There is an associated T-SB-0112-24 with instructions for the installation of the new valve, but that also does not show up on a search.
2. The part number of the new valve is 16260-F0310.
3. It covers only through February 2021 for they hybrid and April 2021 for the Prime. (Was there a production change or a change of parts on those dates?)

Coolant Bypass Valve - dealer told me warranty extended

Just throwing this out there since I haven’t previously heard about this. I’m at the dealer this morning getting the roof rail leak addressed on my 2019 RAV4 XLE with 50k miles. Out of warranty obviously.

The service rep came and told me that I needed the bypass valve replaced too which I already knew. I was planning on getting this done at an independent mechanic that quoted me $600 for the job after a different Toyota dealership previously quoted $1100. I told him this and he said “well they just extended the warranty on the bypass valve too, so we can go ahead and take care of it if you want” - so I’m getting it replaced no charge by Toyota.

Might be worth looking into if you have this Engine Maintenance Required warning on your MID. Maybe it’s a mistake on the dealers part since I can’t find anymore info about this online and i haven’t heard anything since there was talk of a class action, but just spreading the word.

Thank you for this information! We had the Coolant Bypass Valve replaced this past June (2019 RAV4 XLE with 144k miles), and we paid over 1k out of pocket. After seeing your post, I called Toyota Customer Service (800-331-4331) to inquire about the extension and a possible refund, and they told me to place a reimbursement request here:

https://www.toyota.com/support/contact-us/ > Contact Us > Continue > Select Topic recalls > Reimbursement Request.

In the notes add Customer Support Program Campaign Name - 24TE04

Paperwork needed:
  • Proof of ownership (tittle or car registration)
  • Repair order from dealership on company letterhead (or they won't accept it)
  • Cause, condition and remedy statement

It almost seems like Toyota waited this out some, so DIY'ers would be excluded. Sad part is, DIY'ers were not installing the F0300 or the F0310 item, so at some point the F0010 is gonna fail, maybe still then the extended warranty covers it. TBD I guess.

From a different angle, would Honda have handled such issue the same way?

In one of these valve threads you had posted a pic of a failed valve, but it was from the coil getting too hot and it melted a hole through the plastic body, then coolant just leaks out. So we have 3 fail scenarios thus far:
1) the coil melts a hole in the body
2) valve body cracks
3) the coil burns out in some way (open circuit, high to infinite ohms)

I say that's a MM fail for that part! MM = major major ;)

Even more odd, these valves have been failing for many years now, and not just on Rav model. It's really a Whaaaa TF question for Toyota, why they waited so long to try and fix it? I wonder if they had huge inventory on this bad valve from AISIN?

Toyota is screwing ALL owners right up to the 2024 model year with the FEB 2021 vehicle manufacture cut off date in the CSP. All these cars up to 2024 have that defective 16260-F0010 coolant bypass valve and once they are past their basic 3 year/36K miles warranty there is NO FREE REPAIR! DIY guys are doubly screwed because they would NEVER be reimbursed for their labor
