DIY: Repair a Denso starter solenoid from a Toyota
HTML-код
- Опубликовано: 4 янв 2025
- Toyota says it is a "non-serviceable" part. Once it's worn out, you have to replace it with a new one. Is it repairable? Let's find out.
This one is from a Corolla but almost all Toyota cars use this kind of solenoid.
I admire your ability to make repairs using creativity and craftsmanship. Nothing better than fixing something that the manufacturer says can't be fixed.
NICE JOB!
Brilliant repair mate , you’re a breath of fresh air for all blokes of the world that’s programmed to just replace every little thing.
Thanks for all your videos - I like your style and ability to see potential in everything. My house is full of nice things that people threw away and I fixed, from computers to microwaves, stereos, toaster ovens, bicycles, washing machines, motorcycles, snowblowers, lawnmowers, power tools...everything. It kills me what is in our local dump - and now they won't let us take any parts. It's all "recycled" (i.e., destroyed).
AMAZING!! I GREW UP WITH A FATHER THAT COULD FIX MOST ANYTHING--LIKE YOU.I LEARNED A LOT BUT NOT ENOUGH. EVERYTIME YOU REPAIR SOMETHING NEW--YOUR KNOWLEDGE BASE INCREASES, SO FUTURE REPAIRS BECOME NOT AS FORMIDABLE. WHERE DO YOU "FIND THE TIME"? IT'S A DELIGHT ---WATCHING YOUR VIDEOS --FROM A MASTER OF MANY REALMS!
Great determination and very good video! It ain't broke until you cannot fix it anymore is something my grandfather used to tell me. When I was a kid my grandfather showed me how to drill out the rivets on a lawnmower solenoid, clean & grease the contacts, then put it back together with screws. I fixed a lot of them in my life and this is even a better example of fixing a "non-servicable" solenoid.
In México, you get a "10" when you do an excellent job. You've got "100"!
you are a thinker, brilliant, smart and very resourceful. thank you for sharing your knowledge and experience.
I'm an old geezer and this video brought back great memories! GOOD JOB!
Amazing job brother wish I had the patience and skills you do cause I would be fixing everything I could possibly fix by myself
If you were stuck on the side of the road this information is like gold. Ty sir!
I appreciated seeing the inside of your Denso solenoid because I am trying to diagnose why my starter failed the other day. If your Denso solenoid is similar to mine, which is for a 2004 Sienna, then there are 2 concentric coils inside your solenoid. One coil is called the PULL-IN coil. The other coil is called the HOLD-IN coil. Most ohm meters have a resistance in the meter's probe wires and you can determine that resistance by shorting the ends of the probes firmly together and noting the reading (mine was 0.4 ohms). Once you know the resistance of the probe wires, you can subtract that value from the resistance that you measure across each coil. Both coils connect to the same trigger terminal on the solenoid which goes to the key switch. The other end of the PULL-IN coil connects to the stud that receives the heavy braided copper wire from the starter motor. The other end of the HOLD-IN coil connects to the outer shell of the solenoid which is grounded to the engine. My PULL-IN coil measured about 0.4 ohms and my HOLD-IN coil measured about 0.9 ohms. If a bad electrical connection or a broken coil wire prevents the PULL-IN coil from passing current, then the current through the HOLD-IN coil alone will not allow the solenoid to do its two tasks, which is to switch battery current to the starter motor and push the pinion gear forward into the flywheel. After I cleaned up the outside of my solenoid, it is now working properly. I am left to conclude that my starter failed the other day because either the nut on the lower copper stud wasn't tight enough, or there was dirt between surfaces where electrical connections take place, or the miniature relay in the fuse box was not sending 12 volts to the trigger connector on the solenoid for some unknown reason. I hope this additional information helps.
Good work, sir. I also like to fix things as often as possible before throwing them in the trash or recycling pile. Thank you for encouraging me to save money and try this repair.
Very nice! Never considered repairing a starter myself. Thanks for taking the time to do this.
I’d love to see this man gifted a nice new set of pliers .
Legend, thank you, learnt and settled a huge case of curiosity that’s boggles the mind for some time now :)
🙏🏻
I basically done the same thing for my solenoid
For skoda 94
Instead of flipping the copper contact plate
I clean the contact area add a washer for compensating the worn copper it worked like new
You are very kind to show how to repair the car tool.
I did something like this and in addition i welded a copper wire to the worn copper sides with tig welder machine.
I think a small tack wield would be better to secure the crimped ring. Or better yet, have the manufacturer get part number and dimensions so we could buy another or make it to specs.
Great work!
Its a shame manufacturers don't make solenoids a serviceable item, so as well as saving money, the environment/landfill would also benefit.
Your a legend in my eyes. I think you just saved me 300 $
thank you on showing how it looks like inside
Much better if you put epoxy on the opened crimped area so that dirt and water won't go inside. Great DIY repair!
Great video...I'm grateful for your knowledge..sharing is your gift ..thank you have a blessed day and be blessed
Bloody top job mate 👍
Good to see some 'can do' thinking.
Thanks 👏
Wouldn't it be a fantastic world if the american politicians would regulations where a corporation or manufacturer had to make it where all parts could be repaired in pieces and not just throw things away or have to buy a new one. Good job sir.
How are you keeping the water out of the solenoid coil now that the seal is compromised?
Saw a method that I tried today,. You use a nail and hammer to push the folded over part up and away. Then de solder the leads to the coil and remove the top part. After you sand or file the copper contacts smooth you can put the top back on and hammer the metal back in, solder the leads and seal the edge with silicone. It worked very well.
Cleared video thanks for education South Africa motorist will always like you good work
This was great, thank you so much for showing us your skills and helping me...😊
Interesting, I just replaced my 2014 Subaru Outback Starter and plan on rebuilding it later. It's interesting the solenoid can be repaired.
Wow,I am impressed by your clear knowledge of that stater solenoid repair example.Is it possible to reach the solenoids 2 screws at the back to take that solenoid off the starter without removing the whole stater.Thnx
Thanks for teaching me this. Very valuable lesson. Continue your good work.
Thanks! The world needs more people like you. prior to opening is there a way to determine if its the solenoid or the starter motor itself that's an issue?
Absolutely brilliant my man!🇨🇦😉👍👍🎸🎸🍺🍺
wow! that was realy good sir you are awesome!! i wished you were in my family to teach us those things about cars
You sir, are a joy, and an inspiration. Thank you. You are amazing. Thank you for this.
You can compensate the worn by adding a thick washer or steel ball inside the weight where the spring is located
You can get away with this without dissambling
the solenoid
If Fucking Mc Guyver made a series in Vietnamese, you are that man!
Hey man, you are just amazing on repairing stuff. Did you know what kind of repair was required before you attempted to open the solenoid casing? Or you just opened it and came up with the solution as you troubleshot it? I look forward in seeing more of these uploads from you.
Probably just likes to save money and maybe has had this same solenoid with the same car, while also fixing other brands of solenoid’s that are essentially the same thing just made by a different . And im pretty sure he also learns or learned from watching other people make mistakes or make repairs on mistakes that anyone made. -the brain never stops learning-
Nice job. I will try it on my Toyota Allion starter. I removed it yesterday. The motor is rotating but the solenoid is not engaging. When I try to start it whilst attached to the engine its just clicking. The price for a new one is too much if it can be repaired!! The battery is in good condition.
Very good Video and I’m about to fix mine today. Thanks
i wished that all the mechanics were as bright as you are so we al, would have been appreciating the part as it still can be used for such a long time and not just waste the part and the money I WISH THOUGH!,,
This dude is +100% better than MacGyver.
Great video. Thank you. Do you know if this would also apply to a 1997 Toyota rav 4?. My starter keeps running after shutting off the engine. I think the solenoid may be stuck.
What is the problem when you on the ignition the pinion doesnt disengage and when turning off engine it always on even the key is off ?.. but when you direct the starter into battery the engine runs okay and the pinion disengage smoothly also engine off is good
What are the symptoms of a bad solenoid compared to a bad starter motor
Pure Genius!.. When in doubt Macgyver IT!👍
I'm impressed!, Thanks for sharing
What year is your starter from? I thought the older 80s & 90s Toyota starters had a lot more easily replaceable parts, but don't recall exactly. Unless just replacing the whole little solenoid part is the idea?
Good job but I believe the e-clip will last longer than the aluminum washer you installed as once it heats up it'll try to return to it's original shape.
Why didn't he use the circlip, maybe it was too loose?
you sir are a true genius
Good job sir.👍🏻
Brilliant. Saves me some cssh with this
So it's been 2 years how did it hold up
Hi
This is the best video ever made to fix the start motor !!
I subscribe your chanel !!
& wathing your all video~~
May I know what was the size of the thread tap and the screw you used?
Is this solenoid still working, or did it start not working again? 🤔
great video, I got stuck with assembly. everything is in the spec as shown but upon assembly the starter doesn't turn. any cheats
That worked great! Thank you my friend.
Great job buddy. Thank you for useful video.
Great Job in teaching me n bit of your Abilities 😊
Superb....Superb....very very useful ....pal
Superb instructions, Thank you
Did it stay reliable or did it break later?
Could you have soldered a blob of solder on the copper plate to make it thicker?
Good vid 👍
Great video Good job
Yes. Fix everything! 🙏
How do you know if whats bad is the starter is the solenoid?
Good question?
@@donald8354 not really, once is out, you conect it to the battery and you can see what's failing
When the bendix gear does not come out or stay out (bouncing in/out) the solenoid is at fault. If the starter does not spin then it the motor.
Very nice work,,,,worth subscribing
Why if bench test ford ranger starter, it not stay ingage if i keep small wire on pin. It uningage with start small wire on start point. It must only uningage only when i take of start thin wire, am i right or wrong?
Rrrrrealy hope someone can help me. Thanks guys.
Good job. Btw I love your accent.
Great job 👍👍
You’re awesome! 👍
I think you should do something to seal it. because water will destroy everything in the first winter!
You are the king!
Good job.
Great job
Great!, thanks for posting this video and I send you a like too!
Good information! Thank you!
dumb question is a solenoid really just a BIG relay ?
In a way, they are basically the same. They are both relays. The only difference is in their functions. Relay functions as an electrical switch to relay small current to a different circuit with a bigger current. Solenoid does the same thing except that it also needs to move the pinion on the starter to engage with the flywheel. Not only is it an electrical switch, it is also a mechanical switch.
@@vuaeco May I know what was the size of the thread tap and the screw you used?
You'd be dumber if you never asked.
Prob how "dEnSo DoEs iT", thanks for the info!
Exellent video. 100 pts
Can I mail you a solenoid? I'd need every tool you used to rebuild this. 1998 Camry
Amazing, thanks for sharing ❤
Good Job man👌🏽
Well done
An improved design would be: a thinner case w/ groves and shorter screws. What else?
Subbed! Great info thank you.
Sell that homemade clip. Add List of tools needed for this repair in description.
👍🏻👍🏻excellent thank you …
When I worked at Valeo repairing solenoids we used to get new clips for the contact. Much the same as what you made. I used to repair about 150 a day. Bosch 0331 303 ---. We had presses and automatic de solderers. Pity they moved it all to France.
Grate video bro I alway wounder. How that was don now know thank man now I do it my self
Hell yeah!
Was NOT able to separate the solenoid. Tried as shown but screwing the screws in resulted in two bulges in the solenoid housing, it not separating and the housing becoming useless and not rebuildable....
Thanks for nothing.....
You buggered it up, and now you're blaming someone else. Don't lie: Did you use an impact to screw in the screws?
Why not add solder to the worn down copper 😂
Its hard to solder to copper champ. You normally remove the copper enamel just to solder to it
Solder has a low melting temp, the arcing from the contactor creates hot plasma, which is why the copper gets so worn out. Solder would not hold up. Infact theres a chance that the solder could melt and Fuse the two contacts together.
Shape the copper plate smaller w/ a thin titanium coating or self healing amalgam to not wear out.
❤❤
I am surprised you didn't grab one of those 24v semi truck starter and make a bike or some old motorcycle frame in the junkyard 🕳️👅🕳️
See if you can ask another youtuber rhat spwcializes in 2d printing for a new case maybe a sealing band to bo around the crimped metal to plastic boundary
😎👍
Wow.
The C clip would be better it is made of spring steel, it would never come off
Great fudging video. 🎉👏🏻
