  1. I have ordered this
    from Mishimoto. I am hoping it will fit in the filler hole - will test it on receipt - and will also try it in the drain hole when I do the 10k oil change. I like the idea of a larger magnet.

    I would still like to see a used oil analysis on the old fluid. There are companies in North America that routinely do this - mainly for fleets, and it isn't hugely expensive.
  4. I'm a nervous nellie when it comes to this sort of stuff. I've already asked Votex for more info on how they secure and QA the magnet, to which they have replied:
    I bought a similar SST magnetic drain plug for a new VW Golf TDI in 2003. It was supplied with a plastic washer. By the next oil change both the plug and the magnet were loose. Of course the oil gets hot and the diesel engine vibrates.
    But we have the advantage of customer reviews these days and they seem to be highly supportive of Votek's plugs.

    The Mishimoto plug will fit fine but to a large extent the application details are left up to the customer. I'm not sure why Dowty washers are popular as it's not the sealing that's the primary task, it's keeping the plug secure. Dowty washers are made for high pressure hydraulic applications with steel fittings and I'm unsure if the aluminium surround will deform during the install in our lightly-torqued application. The soft washers we are using now of course deform to match the fine detail of both surfaces and as such are good at keeping the plug secure. Sealing against oil seepage is just icing on the cake.

    The long magnet certainly improves the chances of catching particles. It looks like a high quality part but the first thing that I'm thinking about is what sort of material is it (cast or formed) and will it resist the continuous impinging flow of oil. Will there be flow eddies that will induce a vibration and fatigue-stress the magnet in a bending mode? The other issue is differential thermal expansion between the aluminium plug and magnet and how the glue handles that, although the Kona gearbox barely gets lukewarm. My gut says all this is probably fine but my engineering side says don't start off being biased! My conservative take on this, since I don't have the tools to carry out a formal analysis, is that it's more risky than the Votex product and that alone would put me off.

    I believe the short Votex magnet will be sufficiently effective. Particles need to be right there at the magnet to stick, they don't get pulled from far away. Every mm³ of oil containing a particle of steel will have a very high probability of momentarily being adjacent to the magnet over a long period of running time, a wild estimate might be every hour driving. That time could be reduced by increasing the magnetic area or strength but it's going to be good enough.
    My Suzuki 4x4 has very weak ceramic magnets on the various gear oil drain plugs and the oil always comes out in great condition.
    One owner on Reddit said they'd do that but certainly in NZ there are no inexpensive consumer-oriented analysis services like there are in N. America. In any case I'm confident I know what's in it. It's not like in an engine where there are a dozen potential contaminants.


    I did write our NZ importer:

  5. Well, now you've got me dithering. Mishimoto have advised that the plug is on 6-8 week back order and have offered a refund. I want to try this plug but your reasoning has put me off. Maybe I will cancel my order and use a second Votex.

    I would also like to write to the Aussie importer. May I use your words as a basis? (TBH, plagiarise:rolleyes:) I would change the first sentence to something like
    "I have been discussing the following issue with a degreed mechanical engineer with a fair amount of industrial power transmission experience."
    I intend to stress the low mileage and include the photo of the colloidal metal in the oil, along with an offer to send an oil sample for their analysis.
  6. Yeah, sorry, I thought that might happen but I'd prefer to be honest in my opinion. Part of the reason I'd like to stick with a steel plug is that the thermal expansion will be similar or the same and and don't have to worry about cycling the adhesive. A magnet coming adrift in a gearbox would very likely be catastrophic, unlike in an engine where nothing would happen. I'll be checking the Votex at each drain interval.

    You can use whatever seems appropriate from my email and the intro you're suggesting. I also included photos of old oil, Konas identified only by country, model year and kms. And I added a link to the Canadian tech's video, The Off roading Mechanic.

    BTW, is your Kona the series 2 or facelifted version? I'd assumed it was, just verifying, as an owner here has asked if it affects those.

  8. Apology not needed. Though I'm ok with tools and have a tech bent, I never got a degree so am more than happy to defer to knowledge and expertise that's well above my pay grade.:)

    Thanks for the email stuff. I think it's important that Hyundai be informed. I'm not confident that dealers' sausage factory service departments would do any more than remark upon the dirty oil. I doubt they'd join the dots as has been done in this discussion and pass the info up the chain. I am hoping the near-new 4000km result will attract some attention.

    I'm a bit confused about model variants as each market has different spec levels and different names for same. What is the difference between Series 2 and "facelifted"?
    Mine was sold to me here as a 2021 model. It says on the sale contract it's a
    "Hyundai Kona OS.V4 EV Highlander TTR 150kW 64kWh". Build date 04/21. Compliance date (ie Australian Design Rules compliance. I believe you don't have an equivalent.) 05/21. Model code GKW5ZGZ7ZGGBB821.
    It has the plain face, not the dimples, and Michelin Primacy tyres, not Nexens.
    It also has the 10.25 inch screens and rear USB ports which I think are indicative of USA 2022 model/Series 2?

    I would think if it affects my April 2021 vehicle it will affect all of them unless there has been a transmission mod introduced since then which, though possible, I doubt. I think they might have been preoccupied with batteries:D.

  9. Thanks, that confirms it as a "Series II." The dealer just 5 min walk from here has two unregistered examples in white and light grey, both in the so-called "Elite" trim which has pretty much everything except a sunroof. They've been sitting there a while because they're priced too high to qualify (>$80k) for our $8,625 rebate. The base model qualifies, priced at $79,990.
    cheers ...

  10. Don't know if we (NZ and AUS) are the same market for Hyundai now, but here's a link to HA:
    Scroll down to " Find Your Kona Electric" and you'll see our Elite and Highlander feature lists side by side. Full Aussie specs attached.

    There are no federal govt incentives for EVs here - what else would you expect from that useless mob? - but the Highlander trim squeezes in under my home state's (NSW) incentives. I missed out - bought 4 weeks before the announcement came out of the blue:mad:
