This is not simple to fix but you did it efficiently..Thank you for sharing this expertise and please continue this teaching informative videos .. All the best

[@TheYoungBonsaiGuy]

i did this work today, asshole who put it together put every clip behind the hardest part of the engine to take out of. if the clips were facing me, this would have taken 30 min.

Great video first one I seen with correct bleed procedure.

[@MustafaAldhaheri]

Thank you for the Very detailed video The only hard part is to remove the hose clamps as their heads are Facing the engine I have seen some other videos replacing only the valve after disconnecting it from the original hoses but I am not sure it will be safe that way

[@RAV4Guides]

I thought about doing that as well, but you'll risk puncturing the hose, so it's not an ideal solution. I'd recommend replacing those clamps with ones that can be easily removed using a screwdriver. You can get them from any hardware store.

My 2019 RAV4 it went out at about 50,000 mi but I had the extended warranty so I didn't have to pay for it I was weighing in mine out on the highway

[@DreamImLivingln]

Mine has this issue right now but my sensor is dry. I don’t want to pay the $900-1500 to get it fixed. This video was helpful but I did get lost at certain points because I couldn’t see what you were doing.

[@RAV4Guides]

Which points if I may ask?

[@basitmuhammadimran1293]

Can we add 1500 watt inverter in Rav4 prime without tech package? If yes, can you do a video on that?

Toyota OEM part# coolant bypass valve 16671-F2020 for $101.68 and for By-Pass Hose part number 16260-F0010 for $119.45.

[@Rajkumar-pz3pi]

Can u send me the link where can I buy for rav4 2020 LE AWD

Could this valve fail and trip the "engine maintenance required" without tripping a DTC? I inspected the sensor on my 2019 Rav4 and its dry.

[@RAV4Guides]

There are 2 valves btw. The other one I think is behind the AC so that one might be faulty.

[@DONMARIO96]

Can I cut the bypass valve in stead replaceing the whole hose

[@RAV4Guides]

It's a press fit. It's either you replace the valve which is a bit challenging or the whole part with the hose.

[@marklo4416]

Good video but where is the sound of your voice?

[@Zeek800]

This is doable but not easy. Doing it yourself this on a Hybrid would be damn near impossible because of the hybrid cooling and Invertor being right there. Does it always show a leak and where would you notice it? Toyota is really falling way down on reliability, quality and even customer support. They need to stop trying to save $2 or $3 a part by purchasing low quality parts then charging owners $2000 to fix Toyota’s screwup.

[@RAV4Guides]

Yeah this isn't an easy fix, but it's doable if you have the patience and little bit of skills. Also I do agree, Toyota needs to do better. They're charging a lot for these cars with cheap materials and parts.

[@Zeek800]

@ there’s a KZbinr called the Car Care Nut who’s channel was so popular that he quit his job at Toyota where he was a Tech for over 15 years with a specialty in hybrids. His videos are great and are geared towards things you can DIY as well as information about newer Toyotas etc. He calls a spade a spade but when doing a fairly long video on the 2.5 litre engine he made special notice of this coolant temperature control valve and how amazing of a concept it was. He just left Toyota and opened his own shop about 2 years or so ago so maybe he hasn’t seen any of these failures because the engines were pretty much only a couple years old when he stopped working on Toyotas every day of the week. He still works mostly on Toyotas but anyone with this issue is probably still trying to resolve it at a Toyota Dealership under warranty. According to him, Toyota stands behind their vehicles and if there are issues like these they may take their time fixing it but they will ( in the past anyways. I don’t recognize this “ new” Toyota ). $1200 just for the labour? to install a replacement on the gas model??? The hybrid’s inverter is directly in the way so add another couple by the book hoursThe least Toyota could do is to design the part s9 that you only have to replace the plastic part of the valve where the failure seems t9 be coming from.

[@RAV4Guides]

@@Zeek800 It's cheaply designed and possibly done on purpose so they can charge people more money. Unfortunately, most of these companies nowadays care about making profits only. They focus on the marketing more than building quality products. In my other videos I completely replaced the 'premium JBL' sound system due to its cheap components. I'm not sure why they call it premium. But it's a way to suck more money out of the consumer under false advertising.

[@MrPfilip87]

They should fix this for u on warranty terms no?

[@RAV4Guides]

Usually this issue shows after your basic warranty is expired. However, If you have purchased extended warranty and still valid, they'll fix it for you (you'll still pay for the diagnosing fees). Still it's not a permanent fix and it'll happen again in the future. Toyota should do a recall.

[@MrPfilip87]

What millage you got?

[@RAV4Guides]

@@MrPfilip87 It started to show around 50k (km)

[@jjohnson2912]

@@RAV4Guides Just got quoted $1500 to change this; California. There is currently a class action lawsuit, filed in July 2024, for this very issue (Corolla/ RAV4 2019-2024).

[@RAV4Guides]

@@jjohnson2912 That's a complete ripoff. Unfortunately that lawsuit only applies in the US. I live in Canada and there's no such thing so far. Even if it applies to Canadians, we don't even know when it'll be resolved. It could take years until we get recalls and get it fixed. Regardless, if you get it fixed keep the receipts.
