TOYOTA COROLLA "ENGINE MAINTENANCE REQUIRED" MESSAGE DISPLAYED (HOW TO FIX IT)

[@nhano666]

You are very good at making videos. I live in Russia and these cars have little information on repair of any parts, thank you man!

[@moecalderon3555]

Because they hardly breakdown

[@riccisaliba6745]

Thank you so much for this video! I was able to order the part from rockauto for my corolla and my roommate was able to install it with this video. The engine maintenance required prompt is gone now.

[@TheYotaChannel]

Nice!

[@gageozee3625]

I am 25 and have never done anything but oil changes before this. It took me 45 min from start to finish. I would say with this video nearly anyone can do this.

[@ronkato4114]

Great video! One hint, you don’t need to drain the coolant. You don’t lose very much replacing the valve. Once the new valve is installed, top off the reservoir and get the engine to operating temperature to “burp” the system and remove any air pockets, then top off the reservoir again and you’re good to go. Make sure to use the pink super long life coolant (premix) and don’t add any water.

[@murppy9785]

This comment really helped too, I was curious to if I actually needed to drain the coolant or not, thank you.

[@victorflorencio8958]

Man, they tried to charge me 700 to replace that part, thank you for this video.

[@ibiro868]

The fact that this code has a specific warning message means they knew about it at the time of production

[@Billy-zo9bk]

It could be, but there also could be a system wide. check in place that knows what should be there and if it doesn't provide resistance/connectivity back it knows there is something wrong with it. But to be cynical and agree with you, oh yeah they definitely know certain things and with how these cars have the capability to communicate with radio (remote start from app etc) they can send ALL SORTS of information down to oil temp/level as these have oil levels sensors back to Toyota and I wouldn't be surprised if the OS inside these things allow them to "turn off" certain electronics. Scary world, the future of all electrics and that's why govt funded corporations are pushing those things so hard...but with how many electronics are in this and other cars, it's not much of a difference.

[@floodo1]

There is now a Customer Support Program for this 24TE04, so Toyota will replace the valve for free if you have the "Engine Maintenance Required" message on screen. Apparently there is a new part number for the replacement valve so hopefully this will fix the problem permanently. Everyone should be receiving letters in the mail from Toyota about this now. thx for the vid tho very informative

[@TheYotaChannel]

Thank you. You are 100 percent correct.

[@stephenh8092]

Best video of replacing this valve on KZbin. Any idea of what makes these valves go bad? Has Toyota brought out a new and improved valve in 2024? Keep it up man. I'm gonna link this video to Toyota Corolla forums whenever anyone asks about changing that valve.

[@TheYotaChannel]

Coolant over time seeps through the connector and short the terminal pins together.

[@Billy-zo9bk]

​@@TheYotaChannel Love the channel! Would putting some dielectric grease on the pins be a good idea to prevent coolant contact?

[@robertomontanez1163]

There are two very similar valves for the 2021 Corolla 2.0 liter with CVT: The one EVERYONE changes (16671-F2010) and another for the CVT (transmission). How do we get to that second valve (16671-F2020), and how do we test it?

[@jerryhinojosa566]

i have done this and the problem still consist, my heater not working. do you know if there is something else that can be the problem?

[@TheYotaChannel]

Did you bleed the air out of the cooling system? Sometimes, air pockets in the heater hoses can cause a no heat concern.

[@trishwoods2810]

3:09 I just got the same message on my 2020 Toyota Corolla with 60,000 miles. How long can I drive it before taking it to a mechanic for the fix?

[@TheYotaChannel]

You have time. I've seen customers prolonging it for weeks before getting it repaired. It will NOT cause the car to overheat.

[@trishwoods2810]

@@TheYotaChannel thanks so much I was so worried about that because I can’t afford it until next week. Thanks again.

You the best ! Love your job .smart question too​@TheYotaChannel

[@fus3669]

I've had this message on my '20 Corolloa with 76K miles for over 8 months. I'm still trying to find a person to do the job for a reasonable rate as I'm not very 'handy' and don't want to pay the $700-$800 quoted at the dealership for a $100 part and about an hour of labor.

[@jalalthejudge-cm4zm]

@fus3669 just close the gasoline box well . I did it and I'm food now

[@miltonblanchard]

What size how is that you used to drain the coolant?

[@josegodoy7607]

Where I can get the valve? Or the number part ? Thank you !!

[@reysantos3662]

Can you help me with the name of the part or part number ? Because o call the dealer and they told me about 2 valves

[@jaimealvarado-valadez4609]

HELP! What can I use in substitute if the plastic clip from the top of the valve broke when I pulled it forward?

[@natelove187]

The dealership. He said u can't be rough with it

[@Beastiedad]

Part number? 2020 2.0 se has this message.

[@Billy-zo9bk]

At what mileage did you have this problem?

[@JustinBeBustin9]

Nice informative video. Quick question, do you not have to pressurize the cooling system when refilling coolant?

[@RobertYonng]

How do you get the code portable scanners won’t read it?

[@Nonamenofame260]

I have a 2021 SE and I just got the warning light. 43k miles. Does this cause engine damage if not treated asap?

[@TheYotaChannel]

No, it doesn't need to be repaired right away.

[@Nonamenofame260]

Thank you so much. Any time frame to do so? Days, weeks, months? Thank you.

[@martogonzales881]

I took over a year to get it fixed , nothing happened

[@Nonamenofame260]

@@martogonzales881 the dealership changed it at no cost 👌.

@@Nonamenofame260 I have a bumper to bumper warranty. they’re looking at it rn. how did it get changed with no cost for you? I’m scared bc I see all over reddit with people having this exact same problem and it costing around $700 to fix 🥹

[@drsierra1]

Why can't the hoses be pulled off of the valve on the Rav4?

[@gilltalks]

Is it the same steps for a 2019 Camry?

[@flip5525]

Very educational man. How much coolant does a 2.0 corolla needs? 2019 toyota corolla

[@justinsenft5578]

What’s the part number on the bypass valve I have seen 2 different part numbers for bypass valves.

[@ChristianMena-ik4lu]

I just did an alignment and oil change and new tune up and changed one of the coils and still I get engine maintenance light.

[@djsalseromusica5433]

What size hose do you need to put on the radiator on the bottom to drain? Is it ½? I really wanted to drain my coolant so this will be a perfect time while I'm changing bypass val. I just start getting this engine maintenance at 90,5k on 20se

[@Poptartslol5]

Hey, what size hose did you use to remove the coolant from the radiator? my message came up last week and the part finally came.

[@RyanTellier-r5f]

Great video. Do you know a recommended technician in Orlando FL that can perform this repair?

[@TheYotaChannel]

Thank you. As you can see, it's a simple repair. Most technicians at Toyota will easily be able to perform this repair.

[@RyanTellier-r5f]

@@TheYotaChannel Thank you. Estimated cost?

[@carlosgoldsberry8341]

Hi jr. l have a 22 Corolla hatchback. Do I have to replace also ? Thanks

[@TheYotaChannel]

Only if you're getting the "engine maintenance required" message displayed. Make sure you have the same engine in your Corolla hatchback that you see in this video.

[@YungAzoe]

Do you have to bleed the system?

[@yardboy3955]

Good video, thanks

[@edwinortiz6686]

Is it for any Corolla? Mine is. Corolla 2020 SE

[@alvinsimba734]

It’s just for the 2.0 litre engine and your 2020 SE is included

Just went to the dealership and was quoted $750. NO! What is the part number so I can do it myself? I have a 19’ hatchback

Thanks for the how to new subscribers

Thank you for the sub. 🤝🤝🤝

[@dreid4760]

How do you remove the electrical connecter? You did not describe how to do the removal.

[@TheYotaChannel]

There is a connector tab facing towards the windshield. You need to press on the tab and pull up

[@dreid4760]

@@TheYotaChannel Thanks! I had used a mirror to locate the tab towards the windshield side of the connector about halfway down and in the middle. I had to press only in the middle of the connector and was able to pull up.

[@tunckeskin1151]

thanks for the video! Can I do this without draining the coolant?

[@ronkato4114]

Yes, you don’t have to drain the coolant. You don’t loose much when replacing the valve. Just make sure to top off the level in the reservoir, get the engine to operating temperature to “burp” any air pockets and then top off the reservoir level again.

[@jalalthejudge-cm4zm]

Its it too expensive to fix this ?

[@Ziomek26]

What causes the valve to fail? I drive 8-10 hours a day I have a 2021 corolla xse should I be concerned about this happening? My car is at 66,000 Miles. Thank you!

[@ibiro868]

Mine didn’t fail till 128k. I do a lot of highway miles as well.

[@julio-m2i]

I did the same but the engine gets very hot

[@TheYotaChannel]

Did you bleed the air out of the cooling system? And did it run hot prior to the valve replacement?

[@jeffestrada8]

Would this just be solved low coolant levels? Or with topped off level of coolant still causing the message? I have had the message for about 2 weeks now.

[@Hernsama]

No

[@pacitataylor1079]

Where r u

[@a14_herrera60]

My dealership charged me 530 for this lol could’ve done it myself

[@TheYotaChannel]

Yea, you really could've. That's why i always recommend you look on KZbin first to see if you can do it yourself and to see if the price is justified.

[@erikalopez958]

I went today and they are charging me $800! Just $180 for the diagnostic and I said no I’m not giving you $620 more
