Gear oil change in a Hyundai Ioniq Electric 28kWh & fitting magnetic sump plugs

[@rossvincent7506]

Today (NZ time) my son changed the reduction gearbox oil in my newly acquired 2018 28kWh Ioniq Electric, at 81,000 km. We followed your guidance, and the job went very well. The oil was black and certainly needed changing! I got the magnetic sump plugs from our local Toyota dealership, and I got the 70W gear oil from Hyundai. Many thanks for providing the video - and all of your other Ioniq Electric videos.

[@GoGreenAutos]

Thank you. Glad you found it (and the others) useful.

[@igakostas]

​@@GoGreenAutosSorry, in 38kWh is the same oil?

[@dlittlester]

My neighbour has this same car, but he goes to the dealer for servicing. He said the last time he took it in for service, they reprogrammed the computer, and now he gets more range. Good idea for the magnetic drain plugs!

[@ImmortaL778]

I have an 38 KW Ioniq and at 144.000 km my reductiongear was broked, one of the beerings was damaged, they refuse to change under warranty, I pay for a new reductiongear and this video is very informative, I will change the oil from now maybe will last longer than 144k km .

Hello , thank you so much for the information works perfect , Do you know if on Hyundai Kona they are the same ? I think they are the same

[@RickyG84]

Really really helpful guide and tips Matt - I’m going to change the oil in my Ioniq gearbox this weekend so this video has been super useful. For anyone looking to do this I found a Toyota Specialist selling the OEM Toyota plug Matt used for £8.34, they are called Rough Trax and are based in Bristol. Their service was great and plugs arrived really quickly. Never foresaw changing oil in an EV 😂 but I think this is excellent preventative maintenance for any Ioniq/Kona/Niro owner 😊

[@GoGreenAutos]

Glad the video helped. You'll like a video coming up in two weeks time where I take apart an EV gearbox.

[@geo6307]

I change today the gear oil in my ioniq 28, at 100k km. The oil was very dark ( black) . I put some aliexpres magnetic screw with 19 mm socket. I use Motul Gear power lv 70w , 1,1l . Seems to by more quit , or is only my impression.Thanks, your vidéo helping my a lot.

[@williamarmstrong7199]

The oil change in my PHEV differentials frightened me! So I am keen on swapping the oil regularly. It seems to be a specialist oil though and it has to be unable to conduct electricity. I have an MG5 on 83,000 miles so far.

[@KiwiMechEng]

Regarding the comments about ferrous particles and magnets, (a) all gearboxes with steel gears use a magnet (either fixed or on the plug) to retain normal wear particles, it's an essential feature that few powertrain engineers miss; (b) once wear particles pass very close to the magnet (just by chance) and are captured, they don't come off due to the turbulence of the oil. Certainly they aren't just 'collecting' there when the car is parked. (c) Hyundai's round factory magnet is captured loosely in a pocket in the casting and rattles around (a design mistake that started with the Ioniq and continues with the Kona and original Niro, but in the Soul it's square) and as a result of movement under the oil flow rubs those captured particles against the aluminium creating much smaller steel and aluminium particles. Steel particles that are "worked" this way lose their magnetic attraction and go back into the oil. At the same time, aluminium particles rubbed off the housing make the oil black. (d) regarding the magnetic plugs I'm glad you used the Toyota and you're the first to do so, it's a good choice. However I would not suggest that Ioniq owners just go out and buy any 18mm magnetic plug, especially the aluminium-body type. The difference between an engine and a gearbox is that you cannot afford to have the magnet fall out in a gearbox. The reason why I originally picked the Votex DP007 in Nov 2020 was so that myself and other Kona owners could "vet" (validate) the quality of that part, which has since played out favourably. It's true that Nissan plug magnets poke out into the gear oil but I would not advise others to use a longer plug than the Votex or Toyota (in that 35mm clearance) without long term testing. There could be ramifications that are not immediately obvious. (e) regarding oil quality, type and gears, there is nothing wrong with the design of this gearbox. It is designed for the motor RPM and that's why the oil is thin. The only problem is the loose magnet. What you want to do is change the oil once at under 500 miles then again at around 3,000 miles. Adding a magnetic plug is helpful but doesn't completely solve the problem because some particles will still find and be 'ground down' to dust by the spinning factory magnet. But after those 2 initial oil changes the majority of the problem has been addressed as the break-in particle loading has been removed. Further changes could be around every 30,000 miles but the purpose is to clear out fine particles rather than replace worn oil. Hope that's all helpful. Two of my videos might back some of this up: kzbin.info/www/bejne/opWlf3d9l8-Kp8U and kzbin.info/www/bejne/j6LYio2GidCWo6s

[@GoGreenAutos]

Yes all very helpful and good points. I have a video of inside the Hyundai reduction gearbox going live in a few weeks too.

[@alexwade9921]

Drain plug magnets are strong. It’s very hard to clean one when it has particles stuck to it.

[@fire_stick]

It’s back ! I was 3/4 the way through the first time round 👍

[@GoGreenAutos]

Yes sorry. I found a couple of video editing errors in it.

[@tommoger]

Thanks very much! Been meaning to do this for a while. I used magnetic plugs on all my previous ICE cars. Simple things make a big difference!

[@rimgaudastamulevicius8614]

could you add the link where to get the magnetic plug?

[@Owsryudie]

Why a magnetic one? (Because it has an internal magnet which eventually collects debree) but how sure is this, and does it improve a lot of things? Or is it just unproven?

[@wfdTamar]

Just be aware that the factory Hyundai plug is M18. The Toyota plug some people are recommending is M17.

[@davidharvey5161]

Excellent, many thanks. Will you be changing the transmission oil on your Model S?

[@GoGreenAutos]

Yes I will do at some point. I've never yet done a Tesla. My drive unit was replaced under warranty just over a year ago, so there's no rush to do mine yet.

[@AzizIzgin]

@@GoGreenAutosdo you also have videos of how to make service on a Tesla? I’ve just bought a m3 sr 2019 and would like to know how to change oil and do other maintenance on it.

[@GoGreenAutos]

@@AzizIzgin No I don't. But you can download the Tesla service manual online.

[@yannickproulx8519]

@Go Green Autos , Ive just changed the oil in my reducer and the 1.1 liters of oil seem to be like « fill to spill » . I checked the level after putting 1.1L with a bended tierap and the level seem to be flush with the bottom of the fill hole.

[@GoGreenAutos]

Pretty close then. With most gearboxes, you just fill until the oil dribbles out.

[@Acamperfull]

Great info that applies exactly to a Hyundai Kona EV (and possibly Kia Niro/Soul) as well. Red Line MT-LV 70W/75W is another gear oil alternative which also is correct for this application.

[@azizmouminin5863]

I changed my gearbox oil for kia picanto 1.2l 2014 by a garage. He put 3L of 75w90 gl4/gl5 but my question s if should I worry about this amount of oil and the type of oil knowing that my catalogue says sae 70w gl-4 and Capacity 1.3 to 1.4 L? Thank you

[@ferencpinter5325]

Do you have instruction for ioniq 5 oil changing?

[@GoGreenAutos]

No, but all EVs are pretty much the same.....drain and fill back up to the fill plug.

[@dot7107]

Local dealer here in Fin also uses 75w oil because that 70w is difficult to get and that difference doesn't matter if you compare those sae specs. I need to chance those magnetic plugs also because oil in my 90 tkm driven ioniq was black and thick as a tar and there was only like 9 dl of oil left. I drained that oil through paintshop paint filter mesh and luckily there was almost no any metal particles in oil.

[@paska68]

Did you get the plugs and did you buy them from Finland? Can you provide links? Also where did you change the oil and how much it costed?

[@dot7107]

@@paska68 Finally I didn' bought those plugs and I changed only oil, twice. It takes about 30 min to drain and refill reduction gearbox

can I put two magnet, one on the drain plug, one on the filling plug ?

Yes.

[@geo6307]

Can you please tell me what is the inside diameters on the original plugs? Maybe is possible to find a magnet to fit in? Thanks

[@GoGreenAutos]

They're an M18 plug.

[@youtubesque]

for oil changing and tire rodating, I want to use floor jack to lift my ioniq 28 then put it on 4 jack stands. but if the 4 jacking points on each side of the car are used for jack stand, where should I put the floor jack? I can't find any tutorial or video on how lift properly an ioniq ev at home.

[@GoGreenAutos]

Just don't lift on the battery pack or plastic covered areas, but apart from that, they're no different from any other vehicle....jacking points on the cills, load bearing points on the subframes, suspension etc.

[@leejordanful]

If there is a gearbox is there also a clutch? What happens if you are holding the car on the brake? Thanks 😀

[@GoGreenAutos]

There's no clutch required in a EV. If you're not pushing the accelerator, the motor isn't spinning. You do hold an EV on the brakes.

[@judebrown4103]

Hi Matt, another interesting video, thanks. Random question: I use the auto headlights on my Ioniq 38 kWh and I can't find a fog light switch anywhere. Do they come on automatically in the same way main beam does, do you know?🙏 Tia👍

[@GoGreenAutos]

Fog lights aren't automatic. From memory, on your lights stalk (left hand side), twist the end for headlights (you have it on Auto), then look further down the stalk for the fog light switch.

[@royd63uk]

As a none mechanically minded person, i didn't even realise my Ionic had gears. For some reason I thought it was just a spinning motor. Your videos are so informative. Thanks. So is this something that will get changed at a main dealer during one of the services?

[@GoGreenAutos]

All EVs have a single speed gearbox like this, which is also a differential. I think Porsche has or was working on a 2-speed gearbox for their EVs. No, the oil change is not part of a dealers service. All manufacturers (apart from the Mitsubishi i-MiEV) claim the gearbox is sealed for life and no oil changes are required or include it in the service schedule. You might find this recent video interesting too kzbin.info/www/bejne/bZSTmGB5oqt7m5I, where I look at a reduction gearbox.

[@kiae-nirodiariesencore4270]

Thanks Matt for a another informative video. We’ve had a Kia e-Niro from new in March 2019, now on 73,000 km (we live in France)..The Niro and the Ioniq are built on the same platform, though the motors and battery sizes are different of course. I was wondering about changing the reduction gear oil at some point but as you explain below in the comments it isn’t something the dealer would do in the servicing schedule. With Kia warranty being 7 years I’m in a bit of a bind on what to do...not wanting to invalidate the warranty but wanting this car to be a long termer. Any thoughts?

[@GoGreenAutos]

Many worry about warranties. Getting it done by a garage will resolve this. But anyway, no garage would be able to tell its been changed, if you keep the original plugs. Leaving it until it's 7+ years old would be unwise in my opinion. With warranties, let's say you change your own cabin filter...and then the gearbox failed. They wouldn't reject the warranty claim because the cabin filter wasn't changed by them. They would have to prove that the different cabin filter had a knock on effect and caused the gearbox failure, which of course is impossible! Replacing the gearbox oil, if done correctly and with the correct oil grade, is only benefiting the vehicle and prolonging its life.

hi matt, my ioniq 38kwh just had its gearbox/reduction gear replaced under warranty by hyundai… going forward as an uber driver in london, what steps should i take so that it doesnt not happen again? oil change every 10,000 miles ? magnetic bolts ? is my driving style having any impact? i use alot of cruise control… i just want it to keep working, this incident has scared me because after 30,000 miles i will cross 100,000 miles warranty hyundai covers for any vehicle used as a cab.

[@GoGreenAutos]

50k oil changes and ideally add a magnetic drain plug. You could do it at 40K, but I really can't see any benefit doing it any earlier if using a good oil. As for driving, just don't floor it from standstill as the torque can put stress on the diff and gearsets. I've done two videos on the Ioniq reduction gearbox so you can see inside. See kzbin.info/www/bejne/iZ3Nh4donryCbMksi=avYTI_LkE74DWnJj and kzbin.info/www/bejne/g6LFm56crq-nrKcsi=VbtPpRh4ru8QZuYR

No, I've not done an MG EV yet. They may already have a magnetic plug in them. As for the size, you could remove the fill plug and measure it as its bound to be the same size as the drain plug.

[@patrickh7368]

Everyone says how the “EV” motor is directly coupled (via reduction ratio) through the gearbox to drive shafts, i.e no clutch or torque converter etc…. do you know how “neutral” works on transmission selector ..?

[@GoGreenAutos]

While most EVs do have neutral on the gear selector, it's not the same as neutral on a traditional ICE vehicle. The neutral on an EV is not changing anything in the gearbox or disconnecting the wheels from the motor. But instead it's just disconnecting the motor from the rest of the powertrain electronics. It's just just an electrical switch as it were.

[@GoGreenAutos]

Only required for towing or in the car washes that pull the car through.

[@patrickh7368]

@@GoGreenAutos not sure I understand that, do you mean an electromagnetic clutch ?

[@GoGreenAutos]

@@patrickh7368 Not as advanced as that. As far as I know, 'neutral' just turns off the motor controller or something like that. The motor still spins, as does the reduction gearbox. Its just not interacting with the rest of the powertrain (i.e. inverter etc) so you have no regen function either. Its probably just a tiny little relay on a circuit board.
